Essay on Mammals Samples to Take Writing Cues From

Like many other United States National Parks, Badlands is unique unto itself with physical attributes that when they are seen one knows it is Badlands National Park. Located in an area rich with history, the Badlands was created and founded as a national monument in 1939 by President Roosevelt before officially becoming a national park in 1978 (Steiner, 1993). The landscape of buttes, ravines, and hills found in the midst of the prairie of Southwestern South Dakota influenced the Lakota Sioux to call the area, ‘mako sica’ or ‘badlands’ (“South Dakota Legends,” 2003). The Sioux Pine Ridge reservation lies ...

Analysis of GMOs Effects on Human Health

Introduction The study of genetically modified organisms has grown to be a topic of concern in the contemporary world. In particular, there exist regulatory procedures that guide the process of approval of the genetically modified crops and foodstuffs (DeFrancesco 796). The only technique that enables the assessment of such issues is the introduction of the mechanisms like the toxicological tests, for example, in mammals, through the performance of such a process over longer time intervals incorporating detailed blood as well as organ system analysis (Séralini et al. 1). However, it has been challenging to carry out such initiatives ...

Introduction

An ecosystem is defined as the interaction of the organism and other nonliving factors in a certain community. The living components of an ecosystem, such as plants, animals, and other organisms, can be classified as the biotic component of the ecosystem, whereas the environmental conditions such as water amount, humidity, soil nourishment, temperature, and the like are termed as the abiotic factors. In an ecosystem, both the existing biotic and abiotic factors determine what kind of species live there. For example, turtles, which require a large amount of water to live in cannot possibly hope to survive in arid ...

Animal cognition is the mental capacity of animals as well as the study of animals’ mental capacity. The study of mental capacities of animals has stemmed from comparative psychology, which includes studying the conditioning of animals and their learning. Working memory is a major executive function that makes up the cognitive system and deals with information by providing transient holding, processing as well as manipulation. The study of working memory in animals has mainly focused on spatial memory with most of the studies trying to provide a clarification for spatial memory psychological basis together with the hippocampus role.

Introduction

Climate change is among the significant factors impacting ecological diversity on a worldwide scale. The growth of industries and the increasing human population globally have resulted in a rise in the volume of greenhouse gasses, which scientists have argued are the greatest contributors to the menace. The Florida Keys is one of the ecological treasures of the U.S. that continues to be impacted negatively by climate change and anthropogenic activities. This ecological treasure, which is located at the tip of the state of Florida, comprises about 1,700 islands that stretch for more than 200 miles to the west ...

Over a period of 400 million years, animals in the vertebrate category have evolved to a diverse array of life adaptations on earth. Vertebrates represent animals that are most familiar with people and are used for food, adopted as pets and deployed for labor. They include fish, reptiles, birds, amphibians and mammals. The classification system that groups vertebrates according to each of the classes that have been mentioned above utilizes genetics, anatomy, and the evolutionary relationships. Animals are classified starting with the kingdom which is a large body that encompasses animals that have similar characteristics and end up with ...

Introduction

The process of learning in animals and humans come through a series of situations that come together to motivate, and ignite the brains and enable them to repeat specific actions in the face of certain circumstances. The basic logic presented by psychologists and biologists is that there is intrinsic motivation based on the brain which controls the nerves and models of an animal or human being. This implies that an external variable triggers an extrinsic motivation that gets the organism to ignite the internal or intrinsic motivation in order to undertake certain actions and internalize it in order to ...

Dr. Victor Babes and discovery of Babesiosis

Babesiosis also known as piroplasmosis is a tick- borne disease, which is an emerging intra- erythrocytic parasitic infection in human. The parasite first known to affect only cattle but later was found in other mammals as well. The parasite was later found to affect humans as well. The severity of the disease caused by this parasite can range from mild- to moderate- to severe, i.e., causing death by organ failure. Till date approximately 100 species of the Babesia genus has been identified yet only a few has been suggested to be pathogenic in humans. The symptoms more or less ...

Primates are an order of mammals and while they share characteristics with other mammals, they also have their own identifiers that set them apart. For example, since primates rely more on their vision than their sense of smell, they have shortened snouts (Orzech. “Primate Features”). The fact that they rely so heavily on their sight makes perfect sense when considering that they have forward facing eye orbits which gives them the best position for taking in the most amount of visual stimuli (Orzech, “Primate Features”). Primates also have less teeth than other mammals, they do, however, have specific types ...

The climate of Canada is governed by a number of elements of climate which lead to a regional variety of weather patterns in the country. These weather patterns are pertinent in determining the type of climate which each particular region experiences. Climate has many impacts on a country’s ecosystem, sociology and economy, and is therefore a key component in the overall health of any economy. Disruptions to climate can have enduring outcomes for Canada and its people. This paper attempts to discuss the current climactic patterns which occur in Canada, and outlines some ways in which climate change ...

Theory 1: (PBS/NOVA) Peaceful bonobos and Violent Chimpanzees. Because chimpanzees are closely related to humans it is likely that some humans act very much like the violent chimpanzees, however, many humans are peaceful too. Although I would be more likely to state that the reason is within our DNA by strictly looking at the data for both primates, I am actually a believer in both nurture and nature, as evidenced by the fact that although most children are raised by the same people and can have siblings that are completely different in personality traits. Therefore, my belief is ...

Introduction

Seagrass beds are amongst the most productive marine habitats and their wide-ranging distribution. They provide homes and food sources for many marine animals, prevent erosion and provide nurseries for many commercial and recreational fish species. Despite their importance to the environment, seagrass beds are increasingly being decimated by the results of human activities. The destruction of seagrass beds may have serious consequences on the biodiversity of coastal regions and as a consequence, may negatively impact on commercial and recreational fishing, and ultimately all marine species.

Description of Issue

Seagrasses are flowering plants that live in marine and estuarine habitats. They are rooted ...

Scientists, the world over, have a common belief that over 90% of earth’s species have become extinct over the last three billion years that the planet has supported life . It is estimated that there have been at least five mass extinctions spread over millions of years at a time. The latest known mass extinction was towards the end of the Cretaceous period. It is most likely so well known because, the event which occurred over 65 million years ago, caused the end of the dinosaurs. Although in terms of the scale it was smaller than the previous four, ...

Bovine tuberculosis (TB) refers to a chronic bacterial infection of cattle that distresses some species of mammals. It is a substantial zoonosis that may spread to humans, mainly via the consumption of unpasteurized milk or the inhalation of aerosols. In developed nations, eradication initiatives have eliminated or reduced tuberculosis in cattle. As a result, human disease is currently rare. Nevertheless, reservoirs in wildlife may cause eradication challenging. Bovine tuberculosis remains popular in underdeveloped nations, and severe economic losses may take place from livestock mortalities, trade restrictions, and chronic disease. In some circumstances, this disease can similarly be a grave ...

The correlation between climate and vegetation is evident in Africa, where, despite the rapid destruction of natural vegetation by humans and animals, there are still vast areas of natural vegetation. There are two main zones in Sub-Saharan Africa.

During the pre-industrialization year, testing of new medicines was done on human beings, and it led to the death of many innocent people (Miller 327). As a mechanism to stop these deaths biologists and physicists opted to experiment on mammals such as rodents to come up with suitable medicines for various illnesses. However, as time went by and social movements were formed, animal activists groups emerged. The escalating issue that revolves around fighting for animal rights is argumentative and its course not surely justified. Activists for animal rights insist that animals especially mammals should not be experimented on. The ...

Introduction

Even though the concept of evolution is a typical narrative, it remains one of the most highly contentious of the topics. Major disagreements persist in the field, particularly when the evolutionary origin and physical modification of primates are the subject matter of discussion. Because of these differences, lots of significant finds in the field have attracted considerable amounts of opposition from experts depending on the species, or the side angle of evolution one recognizes (Ravosa and Dagosto). Disputes often center around locomotion and posture – whether a particular species was fully upright or could walk bipedally, brain size (intelligence), sexuality ...

Genome imprinting is the latest technique that has genetically modified the face of infertility; it is an epigenetic phenomenon through which the parental origin of a gene is determined based on its expression. 1 There are a vast number of genes in mammals that are marked with their parental origin, and the result of this phenomenon is a single parental allele. These marked genes are known as “imprinted.” They rely on the epigenetic machinery determining their parental identity and maintaining their origin-specific gene expression. There are 100 imprinted genes estimated in human and 200 ...

This social movement unites people with different points of view on the relationship between humans and animals. Maximalist approach adherents believe that we need to waiver farming, animal husbandry, hunting and other ways of using animals for human needs. The main idea can be expressed through a verbal formula: "Man and animals are equal and therefore have equal rights; to kill animals is just as crime, as to kill a person." However, this theory does not hold out to any criticism, as the idea of equality between men and animals is highly irrational. Animal protection extremists, or eco-terrorists affect ...

Did Human Bipedalism Evolve from a Knuckle-walking Ape Ancestor Did Human Bipedalism Evolve from a Knuckle-walking Ape Ancestor

Introduction

The narratives of human evolution are one of the oft-told scientific stories whenever the topic of the origin of man crops up. However, this topic is also one of the thorniest and most highly contentious. There are major disagreements in the manner in which man first came to be, and every interpretation of almost every new find on the matter will be sure to find opposition among scholars on the field (Harcourt-Smith & Aiello, 2004). While there are numerous causes of disputes ...

Summary of the article

Background and perspective Weaning refers to the gradual replacement of breastfeeding with other foods as well as different methods of nurturing. The weaning process is said to begin the minute the baby takes food from a source other than breast milk. This can be in the form of mashed bananas or formula from a bottle. From a medical point of view, it is important for babies to receive breast milk. It is recommended that for ideal and adequate nutrition, a child needs to be exclusively breastfed for the first six months. Medics also insist that nursing of a baby ...

strains?” Researches on viruses have been carried out since time immemorial. Several vaccines, therapeutics, and targeted drug delivery systems have been developed only through extensive research on virulent strains. However, genetic engineering and molecular biology techniques have enabled scientists to manipulate, and develop new recombinant strains that may not occur in nature spontaneously. Proper containment of these engineered strains is essential as they might have properties that are entirely different from their parent strains. In September 2011 a researcher from Erasmus Medical Center, Rotterdam revealed how he had engineered avian influenza strain H5N1, and made it “more receptive to ...

Abstract

The current paper talks about TNR (trap-neuter-release) program. It is a program where un-owned free roaming cats are trapped, surgically sterilized, and treated. The sterilization is done to reduce population. Different reviews by different authors on the matter are looked into in this paper. The paper focuses on the different advantages and disadvantages of the process. Despite it being a humane way of controlling free-roaming cats, it is deemed ineffective. The roaming cats pose a public health risk to humans and other animals. They also predate on the wildlife in the environs, such as birds, reptiles, and other small ...

Research Question: Does a diet such as low fat and low cholesterol really help lower LDL? Hypothesis: It may or may not. Early research sometimes suggested not eating eggs would help lower cholesterol. This resulted in limits for how many eggs one should eat, if any. Determine if a low fat and low cholesterol diet really works with the study outlined below . Compare two groups of patients: one group eliminating foods which may alter LDL levels and one which continues on with their usual diet before diagnosis of the high LDL levels. Foods to be considered are eggs, 2% ...

The fish family includes sharks, whales, hagfish, and lungfish among others. Fish are water vertebrates and can exist in both fresh water and salt water depending on their adaptability. All fish are aquatic, and they survive by breathing oxygen that is dissolved in water. The two primary groups of fish include bony fish and cartilaginous fish. The aquatic habitat and environment are what determine the ecological structure of the fish. The entire system in which the fish lives is what is referred to as the fish ecology. Fish thrive well on sea nutrients, which are found at the bottom ...

REPORT ON BACILLUS SUBTILIS

INTRODUCTION Bacillus subtilis is a gram-positive bacterium. It is saprophytic in nature. Mostly, it has been found that this bacterium exists in the form of spores rather than being biologically active. The ability to form these spores which are referred to as endospores enables them to survive adverse conditions. Some of the B. subtilis are found to be pathogenic for mammals and insects. The habitat of B. subtilis is soil, river and decomposing plant material . B. subtilis can be divided into two major types, one being that which is applied to the foliage of the plant and the other ...

Do we need that Endangered Species Act?

The Endangered Species Act of 1973 was an innovative measure for the future of nature and continues to protect the diversity of the animal and plant kingdom of the United States. This law is important to the survival of all living things because every living organism depends on the life of another living thing to survive, including humans. Aquatic species in Florida are essential for the health of the environment in which it lives. For example, because all creatures and plants depend on each other for survival, when one species is allowed to become extinct, all other species in ...

Sharks are fish; the term refers to a group of around 465 species (Elasmo-research.org).. Scientifically, they are classified in the order Seachimorpha, subclass Elasmobrancii and class Chondrichthyes. Sharks have an exoskeleton composed of cartilage; which makes it flexible and light enough for ease in swimming (Elasmo-research.org).

Size and body structure

They grow to averagely 4.6- 6m long. Due to the large number of shark species, their size vary, ranging from 1 centimeters to as long as 12 meters (Elasmo-research.org).They have 7 gills through which they breathe; the gills are located on both sides of the body. Their teeth are 300 in ...

Primates can be defined as members of the mammalian order Primates and are divided into two subgroups: the prosimians (lorises, lemurs and tarsiesrs) and anthropoids (human, monkeys and apes). Primates share many different traits and characteristics with other mammals, especially regarding hair, teeth, an ability to remain an internal constant body temperature, brain size and a capability to learn. However, there are also features that make primates distinct from other mammals. For example, in contrast to other mammals, primates remained generalized, which means that they keep some traits of their ancestors that other groups of mammals have lost throughout ...

Introduction

Genetically-Modified Organisms as used in agriculture refers to any animals or plants that have been produced using techniques which alter the genetic material in a manner that is outside of natural recombination. Although GMOs have been in existence for many decades, both scientists and the public hold different views concerning their adoption. Today, there are many forms of GMO food products. The majority have one of several of their genes altered while in some instances a new plant is created. For example, the triticale a new plant created by crossing wheat and rye. The biggest driver and what gives ...

Whilst the cumulative effects of global warming are as yet uncertain, what is known is that global warming will affect most of the species living on planet Earth, including cetaceans. Cetaceans are whales, dolphins and porpoises, and they inhabit most of the world’s oceans and some freshwater rivers and lakes in the equatorial zone. Evidence gathered over the last twenty to thirty years has shown that changes in the cetaceans’ habitat will impact on their range, behavior and sustainability. If the species is to survive, they must adapt to climate change. The following is a discussion of how ...

This paper argues that private property is an enduring than a universal feature of our existence as are other elements such as migration, markets, and the State. Private property is both the cause and result of capital and labour in an individualistic society. This description means that it serves both as the cause and consequence of alienated labor. The form of object ownership is one of the enduring aspects of humanity. Throughout history and ages, humans have acquired and valued objects as well as ideas to advance their existence. This realization shows that property is a vital part of ...

Ans1: Growth is defined as the increase in size and mass of a particular organism over a period of time. It is measured in terms of biomass (mass of the organic material). An organism grows by mitosis. Growth stops after certain age of the organism. Growth is quantitative and measured by taking the measurement of height, weight, size and shape of body organs like brain, etc . Development is defined as the process of cells differentiation which helps in the development of the body. It adds complexities to the body (such as organ development). Development of the organism is a ...

Polycystic ovarian syndrome is a common endocrinopathy of the women who are in reproductive age, which is a first cause of the anovulation. GnRH agonists are used in the IVF to avoid premature LH surge before the retrieval of oocyte. Research findings from this study can be significant to various Centers for Reproductive Medicine, and also to all the institutions that practice ART. ...

BP Oil Spill had many negative effects to marine wildlife these effects occurred shortly after the instance while others occurred after the long run.

- This oil coated bird’s feathers and as a result many of the birds lost their buoyancy and capability to regulate their body temperature. Moreover, the oil concentration on the birds’ skin and face led to skin and eye lesions. Most of the birds died following this while the remaining few where infected with diseases. Birds require preening of their feathers so as to remain warm and dry, be able to remove parasites and remain ...

DISCUSS THE ROLE OF ION CURRENTS IN DETERMINING THE SHAPE AND DURATION OF CARDIAC ACTION POTENTIAL

Introduction Selective permeability to various ions is an important characteristic of cell membranes, one that determines myriad cellular functions. In animal cells, ion permeability and the electrical potential generated thereof determines the activity of neurons, myocytes and the like. The electrical potential depends on the concentration of the ions inside and outside any given cell, the permeability of the cell membrane to the ions and the ion channels that are present on the surface of the cell. Cardiac cells also possess different ion channels on their surface. These determine the two types of electrical potentials, namely, resting membrane ...

The Ozark Big Eared Bats (Corynorhinus townsendii ingens) are found in different habitats accross the United States. They are limited in number and are found in Missouri, Arkansas, Oklahoma; however, it was reported that they are no longer found in Missouri because of the destruction of the environment. In Oklahoma, they are found in Adair County and adjacent parts of Cherokee and Delaware counties. In the early 1970s, the Ozark big eared bats were documented to only be a hundred in Missouri. With efforts in the l980s, it was reported that an increase in number among these creatures have occurred. ...

It seems that there is no subject surrounded in so much taboo as when it comes to sexual attitudes and behaviors. With such a myriad of what is considered “normal” within a certain society or culture, trying to identify what is socially acceptable can be, at times, tricky. Media bombards viewers with images of scantily clad individuals in various adulterous escapades and the spam folders of emails are chock full of advertisements for discreet illicit affairs. With companies catering towards married individuals boasting over 20 million customers (Woo, 2013), is it possible that humans are not meant to be monogamous? ...

In this paper, I would like to give an in-depth discussion about human evolution. I prefer humans to any other species because they are the most advanced. It is the only species which has the highest degree of moral sensibility and mental capacity. Hence, it has a portrayed a behavioral modernity characterized by a highly developed culture, technology and language (Johanson, D. & Wong, K., 2007).

According to Charles Darwin, the process of human evolution took place so gradually. It was as a result of divergence that this species was able to transit from others. Initially, the mammals were living together and had ...

Define the terms ecology, ecosystem, and biosphere.

Ecology may be referred as the study of how organisms interact in their environment including both the physical (abiotic) and the living (biotic) aspects of the environment. Ecosystems endure through the (abiotic) and (biotic) relations within them. It also studies the community and the population, and assesses cause and effects of the reactions of communities and populations to change in environment.

On the other hand, an ecosystem may be referred to as a community of organisms that interrelate with each other and the non-living elements for sustainable adaptation and development to varying conditions. There many different forms of ecosystems that ...

The current status of our wildlife species has been the focus of may ecological advocacies because of the fact that most of the wildlife is becoming threatened. The main cause of this is due to anthropogenic activities, which includes destruction of habitat by men, hunting, illegal trade and medicinal value.

It is not a secret to anyone that our body and the systems it consists of are controlled by a number of things. Naturally, everyone thinks of our brain as a control organ, when it comes to sending order within our body, however, not everyone knows that there are also hormones that shape our entire life. There are two regulatory systems by which the body adjusts to changes in the environment, circumstances and our daily routine. The first one is our central nervous system, with our brain as a major organ in that system, quickly transmitting a signal (in pulses) via a network of nerves ...

Infant care and production in tamarins

Infant care and production in Tamarins: An Introduction Parenting patterns vary extensively both amongst human and primates. Cooperative care is rather unusual in the primates, however; it is found mainly in tamarins (Saguinus oedipus), the small monkeys. This report delves into infant care and production in tamarins, in a social system, explaining the methods they maintain their relationships in a cooperative care.

When offered an option for caretaking of mother or the father, infants generally prefer the father, who offer more care. Hence, in biparental and cooperative breeding groups, the infants do not create a major fondness to the mother or ...

- The stromal cells that are found in the developing gonads of tetrapods begin from the medulla from the peritoneal wall and the cortex from inter-renal blastema or mesonephric. Hence the gonads have a dual origin. - Spermatogenesis occurs in a syncytial complex because it involves the formation of sperm from undifferentiated cells that are first attached to rachis. Syncytial cell complex or syncytium result when cells with single nuclei fuse to for a cell with nucleus. Syncytial cell complex is vital in oogenesis in that it assists in the differentiation of cells. One other developmental model is vitellogenesis. - ...

Nature is structured into ecosystems that play an important role in keeping the environment and biodiversity healthy. Being a part of nature, humans too can help maintain the environment and wildlife health by creating the garden ecosystem. Building a garden ecosystem enhances biodiversity since it attracts a host of wildlife and provides them with food and a safe habitat for living and reproducing. Such an ecosystem also benefits the environment by limiting air, water and soil pollution. It also regulates local atmospheric temperature and flow of water. Specific types of garden ecosystems also allow for organic farming that permits the production of healthier ...

Analysis of Temporal Trends in Persistent Organic Pollutants in

Analysis of Temporal Trends in Persistent Organic Pollutants in Air, Water, Food Chain and Humans in United States Introduction Persistent Organic Pollutants (POPs) are synthetic organic chemicals, which are persistent in environment. Its long-range transport leads to global pollution. These materials are lipophilic and they are accumulated in the food chain as they are found in fish and marine mammals (Arnot & Gobas, 2006). These toxic materials are spread in environment through different human activities. They pose adverse effects on air, water, food chain and humans. In United States, over the last two decades there has been a continuous ...

Climate change in the Arctic region can be considered to be the most serious environmental issue that is threatening the Arctic environment. Apparently, the annual average temperature in this region has been gradually increasing by approximately double the total global average temperature (Symon, Lelani and O W, 123). It has become evident that human activities are the single most cause of climate change, even the government of US has at last admitted to this fact. During the past few years, the Arctic environment has warmed at alarming rate, and scientist predict that it is still going to continue by ...

Sensory Perception

The Nervous system plays an important role in many mammals including man. The nervous system is responsible for the coordination of different stimuli in the body. Environmental changes can be felt in the body due to the nervous system present. The sense of touch, vision, audition and taste can be understood solely due to the nervous system. A minute change or deficiency in these senses could lead to fatality. A failure in perception of any of the senses makes an individual dependent. Sensory perception is essential for all living organisms and forms the basis for homeostasis. A ...

Oceans and seas seem to be safe from over-exploitation of man. However, research proves that the above statement is not true. I want to argue that the marine ecosystem is not safe from man’s abuse of its resources which leads to the decline of marine mammals such as whales, and dolphins. Whaling is a highly controversial issue amongst the animal rights movements. Because of the decline in the number of marine mammals, whaling is a barbaric deed that must not be tolerated. Marine mammals such as whales are certainly in the brink of extinction (Climate Institute.org, 2014). Commercial whalers and ...

Introduction

The study explored the homological characteristics of 22 species. The organisms were human, pygmy chimpanzee, common chimpanzee, gorilla, orangutan, white-handed gibbon, macaque (Cercopithecine monkey), horse, bison, cat, dog, bird, bat, frog, rattlesnake, alligator, fish, whale, wolf, pig, bacteria, and cow. The species were categorized as mammals, reptiles, birds, fish, or amphibians. However, humans and apes were further classified as primates. Moreover, the research sought to determine whether the species share characteristics that link them to a common ancestor. The research hypothesis was that if the evolutionary path of the 22 organisms were traced, then a common ancestor would be observed.

Canine Micro Biomes Affected by their Diet

Canines Micro Biomes Affected by their Diet Abstract Dogs and other cats alike suffer from similar maladies faced by humans. The similarity in the maladies between the two groups of organisms stems from the ability to suffer infections from microbiomes of the gut. However, most of the research and knowledge on canine microbiome is not comprehensive to enable the deduction of accurate and precise conclusions. Recently, the molecular studies conducted on the cat family indicated that there are complex microbiomes in the gastrointestinal tract of then organism. The family of microbiomes includes archaeal, fungal, bacterial, and viral ...
