Minerals are natural inorganic substances that are found in rocks and soil and are considered essential components for human survival. Minerals compose an estimate 4% of the body and are necessary for normal functioning of the body. Humans are incapable of producing minerals which is why it is necessary to obtain minerals from plant and meat sources. Soil contains nearly 45% of minerals, wherein plants absorb all natural minerals which is absorbed in the human body upon consumption (Ward 2014). 18 minerals are considered essential out of the total 103 known minerals. Some of the major function so minerals ...

Based on current evidence, most healthcare professionals, physicians, and microbiologists consider blood culture as one of the most essential parameters in laboratory assessment, especially in the emergency department (ED) (Patton, 2016). It is important for nursing professionals in the ED to identify, assess, implement, and evaluate effective strategies to prevent and control blood culture contaminations (Bentley, et al. 2016). As per recent guidelines and recommendations, nurses involved in the ED can follow the PICO format for the prevention and control of blood culture contamination (Snyder, et al. 2012). Population (P): Patients admitted in the emergency care department. Most ...

The study of endocrinology looks into ordinary and abnormal hormonal behavior. The endocrine system includes internal organs that secretes hormones. That is to say, endocrine glands secrete hormones into the bloodstream. These endocrine glands are essential organs of the human body that imperative to maintain various human functions, not to mention, life itself. Hormonal glands that make up the endocrine system influence many relevant factors such as pregnancy, capability to breast feed, and also the process of a child developing normally. The endocrine system aids in the regulation of a human’s basic bodily functions. Given that, these functions ...

Hypothyroidism is an endocrine disorder that results from thyroid hormonal deficiency. In the U.S. and other regions that have sufficient iodine consumption, autoimmune thyroid or the Hashimoto disease, normally causes hypothyroidism, while worldwide, iodine deficiency is the leading cause.

Pathophysiology

Hypothyroidism can be caused by malfunctioning of the hypothalamus, thyroid, or pituitary gland, as all of these result from the same “negative feedback mechanism” (McCann, 2011, p. 496). Despite belonging to the same mechanism the hypothalamus malfunction rarely causes hypothyroidism, and when it does, it is called ‘secondary hypothyroidism’. While the malfunction of the gland is referred to as ‘primary ...

The periodic table of elements, by far, stands among the most notable discoveries in the history of chemistry. Nowadays, probably everyone who has ever heard about chemistry heard about the periodic table of elements. Its implications on the scientific world are so enormous that it has even leaked out to the general public and have become associated with the chemistry itself. This is not surprising considering the scientific strength of this instrument. Using the periodic table, many characteristic properties of the elements can be predicted and many phenomena can be explained. This discovery put so much scientific knowledge together, ...

Human development patterns allow us in making generalizations concerning various stages as the infancy phase, childhood phase, adolescence, and finally the adulthood stage. For the first year following the birth, a baby is referred to as an infant. The childhood stage begins in the second year after birth and stretches until adolescence. Childhood stage is often divided into early childhood and middle childhood. Early childhood includes the pre-school years whereas middle childhood stage includes elementary school years, through the fifth or sixth grade. The adolescence stage is the second last stage of human development before adulthood. This stage is ...

Homeostasis refers to any self-regulating process by which biological systems attempt to maintain stability despite changes in the external and internal environment (Sturmberg & Martin, 2013). Biological systems interact with each other to maintain a suitable condition of the internal environment for the survival of the living organism. The biological systems of the living organism are in a state of constant change. The regulation of the systems within a given range of various conditions helps to keep the living organisms alive and healthy. The systems also interact with the external environment in different ways. The conditions of the external environment ...

Introduction: Plant cells photosynthesize to produce glucose. By doing this, light energy, coming from the sun, is transformed in chemical energy, glucose. Oxygen is also produced from carbon dioxide and water. The process occurs by light dependent reactions (in thylakoids) and dark dependent reactions (in the stroma). In the light, plants produce energy molecules, such as ATP and NADPH; in the dark, they use those molecules to fix the CO2. The excess of glucose during photosynthesis can convert into starch.

Purpose:

The purpose of this experiment was to determine the differences between leaves from plants exposed to the sun and ...

Abstract

Historical events have an impact on the lives of people living at the time, and those residing in the future. They also contribute to the evolution of societies in terms of their structure, attitudes, and preparedness for similar occurrences in the years to come. These events can be social, political, technological, economic, and ecological in nature. Nevertheless, one event can touch all these facets on either a minor or major scale. This paper explores some of the events that shaped human history, and their impacts on modern policymaking. The Chernobyl nuclear disaster of 1986 revolutionized the way industrialized nations ...

The Fukushima Daichi is a technological disaster triggered by natural calamities on March 11th, 2011, when a massive earthquake measuring 9.0 on the Richter scale hit Japan. The earthquake originated from Honshu Island, and it created a tsunami. Following the tremor, reactors one, two and three automatically shut down. Reactors 4, 5 and 6 had been previously shut down for maintenance and repairs. Due to felled power supply lines, the Fukushima Daichi reactor complex was cut off from the electricity grid. As the operating reactors had shut down, they could not generate power for them to cool down, and ...

Abstract

The experiment was performed to analyze the outcomes of temperature on the ability of fungal and bacterial amylase to breakdown starch to maltose. Therefore, the study will reveal the optimal temperature for amylase activity. The initial steps include preparing the materials and tools used during the experiment. A timetable for comparing temperature and function was generated. Test tubes and plates were properly labeled. Iodine was needed for every spot plate so that the fungal amylase, bacterial amylase, fungal amylase and the starch solution can be added to the iodine in a time and temperature dependent fashion. Observing ...

An organic molecule refers the molecules of living things composed of carbon atoms organized in rings or chains on which other elements like gasses (nitrogen, hydrogen, and oxygen) attaches themselves.

Purposes of the experiments

The experiment would test food sample for the presence of organic molecules i.e. proteins, polysaccharides, and sugar.

Question

Would reagent used in this experiment identify the organic molecules? Hypothesis Reagents Benedict’s solutions, Biurets solution, and iodine would establish the presence of sugars, proteins, and starch respectively. Setup of the experiment Materials Benedict solution that is a blue in color and contains copper ions. It is used in the laboratory ...
