Difference Between Anatomy and Physiology

Anatomy and Physiology are probably 2 of many different sciences necessary for the best understanding of the human body and how it functions. So I believe that in order to compare two things, you need to explain what each are first. ANATOMY is the study of the human body. It can also be defined as being the study of how various parts of the body interact and work together. PHYSIOLOGY is the study of how living organisms function. That includes…

Task 2

This article establishes diagnosis and management guidelines for the treatment of AOM. Additionally, the authors make recommendations regarding treatment options for the symptoms of AOM and address the concept of watchful waiting as opposed to immediate antibiotic therapy. Recommendations are provided for clinical practice and were created using a systematic review of clinical research, making it an appropriate source for nursing practice. Evidence based guideline (Block, 1997) Unfiltered Appropriate: This article contains up to date research obtained by the authors…

How Organism Evolved Physiologically

Organisms adapt to their environment but what happens when an organism’s surroundings and environment change? Physiological ecology is the study and understanding of that mechanism of living organisms and how living things work. Physiological ecology arises with an understanding of the influence of temperatures. Temperature, along with others, is one of the most important factors of Physiological ecology. “Water that is available is another major focus all the organisms that contain water in environments and disburse energy.” (“Adaptation”, 2013). Many…

Cell Bio Lab Report

The purpose of this lab was to test the biological activity of ConA by performing a hemagglutination assay. If ConA is active then agglutination will occur due to ConA’s free receptors being able to bind to the glucose residues on the sheep’s red blood cells. If ConA is not active then no agglutination will occur. To test the hemagglutination reaction, two types of ConA solutions were compared, a purchased control ConA solution in buffer as the positive control, and a…

The Role of Energy in the Body

In our bodies we need energy so that we could do things that are possible such as; move our muscles, talk and all the other things that we do. Without energy all people would be useless not being able to do anything. Energy is needed to extract the oxygen from the areas in our bodies and diffuse it into our bloodstream. As warm blooded people we can only digest food and function if our bodies are at a certain temperature…

Biology Lab Report _independent Assortment & Dihybrid Cross_

Introduction: In genetics, when crossing a purebred white flower with a purple flower, we might expect its offspring to be a blend of both colors. Instead, we see that its offspring is purple as well. This is led to be by one trait being dominant over another trait. Gregor Mendel came up with a theory that each member of a pair of homologous chromosomes separates independently of the members of other pairs so the results would be random. This law…

The Reproductive System

Human’s reproductive system undergoes through a sexual reproduction wherein the sperm cells secreted by the male reproductive organ meets the egg cell which fertilizes inside a female reproductive organ. In the case of Human who are considered as viviparous kind of organism, we are considered as life-bearing organisms wherein the young organisms or babies spend their development span within the female’s reproductive tract which is said to be the fallopian tract and when the time span of the young beings…

Omega 3 and Omega 6 Fatty Acids_ Balance of Essential Dietary Lipids for Good Health

Omega-3 and omega-6 polyunsaturated fatty acids are important lipids which are obtained by the body mainly from fish, nut, vegetable and seed oils. These are biomolecules which should necessarily be incorporated in the diet for proper development, physical and behavioral functions in humans and animals. Our ability to synthesize these fatty acids or to interconvert them from other molecules is averted by the absence of enzymes required for their production of transformation in the body. This class of fatty acids…

Etosha_ Place of Dry Water

Etosha is an ecosystem that contains many interacting species of organisms and their physical environment. As the seasons change, the temperature and climate affect the biotic and abiotic factors. Biotic factors are the living organisms that are affected by abiotic factors. Abiotic factors are the non-living or physical factor that directly affects the living organisms. Etosha displays all type of biotic and abiotic factors as the seasons change and the rainy seasons come again to start the cycle again. A…

Animal Cells_ Structures and Organelles

The following are examples of structures and organelles that can be found in typical animal cells: * Centrioles – organize the assembly of microtubules during cell division. * Cytoplasm – gel-like substance within the cell. * Endoplasmic Reticulum – extensive network of membranes composed of both regions with ribosomes (rough ER) and regions without ribosomes (smooth ER). * Golgi Complex – responsible for manufacturing, storing and shipping certain cellular products. * Lysosomes – sacs of enzymes that digest cellular macromolecules…

Alkaline Phosphatase

The Effects of varying p-Nitrophenyl Phosphate concentrations on Alkaline Phosphatase Activity Nathan Overholt Louis Settembrino March 5, 2002 Abstract: The enzyme Alkaline Phosphatase was set up in solutions of varying p-nitrophenyl phosphate concentrations. A fixed time assay was used to find the Michaelis constant and Vmax. All solutions were incubated at 30 C° for 30 mins. Absorbances were measured at 405 nm, and the Km was found to be 0.002 M (pNPP) and the Vmax to be 0.433 A/min. Introduction:…

Heart Dissection Practical Report

Introduction On the of July 2002, a sheep’s heart was examined by dissection. The heart is a muscle in all mammalian bodies that is used to pump blood and nutrients throughout the body. A sheep’s heart was used in this prac because like the human heart it has four chambers and is similar in size. Two of these chambers are receiving chambers called the left and right atrium. The other two are pumping chambers called the right and left ventricle….

Eukaryotic Transcriptional Activator

Introduction             Much of what was initially known about transcription came from pioneering prokaryotic transcription studies that followed the1959 discovery of RNA polymerase. During those earlier times, it was presumed that gene structure and transcription in bacteria were practically the same for eukaryotes. This later turned out to be incorrect since eukaryotic DNA assumes higher-order structural forms and transcriptional and regulatory processes in eukaryotes are much more complex. Thus, studies on eukaryotic transcription have become invaluable in further understanding this…
