Reptiles College Essays Samples For Students

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

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 ...

Lesson 5 Answers:

24.) Plants are classified into four major groups: Bryophytes, Pteridophytes, Gymnosperms and lastly the Angiosperms. Bryophytes are the plants that do not have true vascular systems, which consist of the xylem and the phloem. In this group, includes the mosses, liverworts and hornworts. Together, they are considered as land plants that reproduce their own asexually by producing spores. Spores are produced in the ‘sporangium’ (plural sporangia), a bulb-like structure located at the top of the stalk. It can only be seen through the use of high powered microscope. Because they lack vessels that can bring the nutrients from the roots ...

Ordovician-Silurian mass extinction is one of the greatest mass extinction in the history. According to statistics, over one hundred families became extinct. This was associated with the movement and fragmentation of the supercontinent. Secondly was as a result of ocean cooling beyond levels the organisms could survive. While the organisms had initially adapted to the warm tropical conditions, the sudden transition to the cold climate was unbearable for most organisms (“Ordovician”,n.d.)..
The late Devonian mass extinction is thought to have been warm and dry period. It was characterized by Devonian fish that was the main components of ...

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.

Question2

Isolating mechanisms is the reproductive features which inhibit species from fusing. They are mainly significant in the genetic species concept, whereby species of organisms are distinct by generative isolation, that is, an absence of gene mixture. They include:
- Premating isolating mechanisms – these are aspects that cause species to mate with their own kind (assortative mating), thus prevents the union of gametes to forma zygote. An example is a behavioral isolation technique where prospective mates meet, but select members of their own species.
- Post-mating isolating mechanisms –this involves issues regarding genomic mismatch, sterility hybrid or in-viability which ...

The temperate climate of South Florida provides a suitable environment for a large variety of plants and animals in the area (Kras, 2009). Its unique water habitat provides a home for many reptiles and other endangered species such as the manatee, the Florida panther and the wood stork. In addition, most of the wading birds are endangered and need to be preserved.

Birds

According to Kras (2009), more than 360 species of birds exist or visit the Everglades. Some of this includes wading birds, of which currently about 90 to 95 percent have disappeared. This is because of construction of dikes and poor ...

Introduction

Evolution is the change animals and species undergo over time to adapt to certain environmental changes and eventually produce multiple descendent species. Evolution and natural selection are often taken as complimentary to each other. However, evolution, by definition, is a historical process of change, while natural selection is merely a mechanism that results in this change. Advances in technology and biology has thrown light on several causes and consequences of evolution. Some of the deepest understandings of evolution come from understanding fossils and examining phylogeny and from the study of natural selection. Evidences suggest that when natural selection is strong, the rate ...

God has created all creatures. It is amazing to discover that each creature is unique in its own sense and does not resemble the other creature completely. The various creatures on earth, including plants and animals differ greatly from each other on the basis of their outer morphology and inner anatomy. Humans are considered the most intelligent creatures on earth and they utilize animals extensively for research and development of inventions that may benefit the mankind in the future.
It is estimated that nearly 26 million animals are used everyday for scientific and commercial testing in the USA . ...

Background and significance of the problem

Salmonella species are a group of Gram-negative enterobacteria associated with human and animal infections. There are two types of Salmonella strains viz. Typhoid Salmonella and non-typhoid Salmonella (NTS). The former causes enteric fever that leads to significant morbidity and mortality, especially in the developing countries. The epidemiology of Salmonella infections vary considerably depending on the species involved. The enteric fever caused by S. typhi and S. paratyphi is severe and life threatening condition whereas NTS infections are self-limiting. Humans serve as the reservoirs for typhoid Salmonella that transmits predominantly through water. On the contrary, NTS strains harbor animals as reservoirs ...

Introduction

Geology is part science which deals with the study of the structure of the earth. Plate tectonic, climate and evolutionary history of humans’ shows the history of the universe and this is attributed to the large amount of geological information on the various processes. Geology also plays a significant role in explaining mineral and hydrocarbon exploitation and exploration, geotechnical engineering and also the natural hazards. Things like rocks and minerals, fossils and lithology encompass geology, and they are present in different parts of the world including Rolla city.
Rolla city is known for its many rocks, minerals, and fossils. ...

While anyone - regardless of the strength, potential or life experience - can be injured by threatening situation, for infants and young children the probability of this is higher. Childhood is a special time in the life of every human being. Light, joyful, carefree. Time when the trees seem to be big, and all the problems minor, because around are the closest people - mom and dad. Interestingly, as children we all dream to become adults, and in adult life, with a feeling of light grief remembering childhood (Van der Kolk, 2003). And no matter how many years a person is, he/she ...

Charles Darwin published his masterpiece detailing his theory of evolution by natural selection, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life in 1859. Despite the overwhelming consensus of the scientific community, there are still loud and politically active Creationists that insist that the earth is less than 10,000 years old because the Bible says so. However, the Bible never actually states how old the universe or the earth is. Belief that there is a Creator and in the theory of evolution are compatible for followers of ...

Jurassic Park (1993) is a theme park hosting an array of non-animatronic entertainment that delights, excites, and horrifies its tourists. Despite their beauty and aggression, some of the animals represented are not where they belong. Under a geological lens, not a few but the majority of the reptilian cast represented are sorely misplace if not lost from their respective place in time. Though several of them are present for the sake an audience, it matters that such a blockbuster hit names its main event after the wrong era.
The species of Jurassic Park whose range of existence was within one of the ...
