Physiology Linder Unit 1 Possible Essay Questions Chapter 1 1. Describe the concept of homeostasis. Explain how negative feedback and positive feedback loops effect the homeostatic condition. Use examples to explain your answer. Homeostasis can be described as maintaining a relatively internal environment even though the external environment is variable. Negative feedback loops effect the homeostatic condition by controlling it by bringing you back to your set point

Cycles in Biology Cycles in biology play a fundamental role in the world that we live in. Cycles occur all around and inside of us in many different forms‚ from the Krebs to the Calvin cycle. There are large scale cycles happening and they are essential in regulating the nutrients and substances that are around us which without‚ life on earth could no function. One of the largest cycles that occurs all around us is in everyday life is the carbon cycle. The current atmospheric

Ka Zhu The Importance of the Structure of DNA Understanding ideas at a macroscopic scale is simple. Looking at a clock‚ observing and understanding the movements of the hands over the numbered surface are‚ in essence‚ all one requires to use the device. In order for innovation to occur‚ it is imperative to understand the inner workings of the device on a microscopic scale to modulate its properties. Such is the case for many innovations in science‚ from the heat engine to penicillin‚ and is no

fertilization‚ this cell copied itself to make two cells. This was your first experience of mitosis. Soon after‚ these two cells copied themselves to make four and so on. You have been subject to mitosis ever since (billions of times). By copying the original 46 chromosomes‚ your body has created more than a hundred billion kilometers of DNA - that ’s enough to stretch around the Earth 2‚500 times. Mitosis has copied a total of about 100 ZB of data. As a rough estimate‚ this is equivalent to making

Biomolecules - Organic compounds is first due to the fact that every word on the list is an organic compound‚ as they are essential to life processes. Next‚ carbohydrates‚ lipids‚ proteins‚ and nucleic acids are all macromolecules‚ as they are very large molecules composed of thousands of atoms or more. The map then divides into the four biomolecules. Carbohydrates are composed of monosaccharides‚ disaccharides‚ and polysaccharides. Proteins are made of amino acids‚ which are themselves made of polypeptides
