Review Sheet Exercise 1 Cell Transport Mechanisms and Permeability Activity 1: Simulating Dialysis (Simple Diffusion) • Describe two variables that affect the rate of diffusion: Two variables that affect the rate of diffusion are size and concentration gradient. The molecular size vs the MWCO size of the membrane can either increase‚ decrease‚ or prevent diffusion. The greater the concentration gradient the greater the diffusion rate due to molecules moving from areas of higher concentration

Are GMO’s are No or Go? There is much controversy over whether or not GMO’s‚ or genetically modified organisms‚ benefit us and should be allowed‚ or if they are more harmful and should be banned. Genetically modified foods are beneficial because they save money‚ have greater resistance to pests and viruses‚ and they can hold more nutrition than regular foods. One of the crops that have most widely been genetically modified is corn. Biologists can inject genes in the corn that make the corn resistant

CHAPTER 1 Coagulation Pathway and Physiology Jerry B. Lefkowitz‚ MD Introduction Our understanding of blood clotting is intimately tied to the history of civilization. With the advent of writing 5000 years ago‚ it could be argued that the first symbols used for blood‚ bleeding‚ or clotting represented the first published coagulation pathway. The ancient peoples of the world always held blood in utmost mystical esteem. Through the ages‚ this esteem has been transmitted to modern times in the

Physiology : Eating • Digestive system – stores and uses energy – Absorption & Fasting – See diagrams • Describe how brain & rest of body controls eating (100%) or role of Hypothalamus Metabolism – Absorption & Fasting When we eat we must obtain adequate amounts of carbohydrates‚ fats‚ amino acids‚ vitamins and minerals to construct and maintain our organs‚ to obtain energy for muscular movement and for keeping our bodies warm. Most of the molecules we eat get ‘burned’ to provide the

Genetically Modified Organisms (GMOs) Nature‚ Science and Moral Autonomy Genetically modified organisms (GMOs) and genetically modified foods (GM foods) have become a highly contested topic in public debate. The controversies are the result of differing views from scientists‚ philosophers‚ economists‚ and even politicians concerning the products of “new biotechnology” in particular with regard to recombinant DNA (rDNA) technology. rDNA technology has allowed scientists to move genes across species’

What is exercise physiology? Exercise physiology is the science that describes‚ explains and uses the body’s response to exercise and adaption to exercise to maximise human physical potential. Exercise physiology is very important in touch because the amount of physical activity our body can tolerate‚ the better we will play for the longest amount of time. ATP/CP system is used by the body to produce ATP quickly in the absence of oxygen. High intensity activities lasting for less than 10 seconds

2. Compare the development of lymphocytes with other formed elements. B lymphocytes develop in red bone marrow‚ T lymphocytes develop in red bone marrow and mature in the thymus; the other formed elements develop in red bone marrow 3. What is erythropoiesis? Which factors speed up and slow down erythropoiesis? Erythropoiesis is the process by which red blood cells (erythrocytes) are produced. If you lose a lot of blood‚ erythropoiesis will speed up; anemia can cause erythropoiesis to slow down
