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

As discussed in the intro‚ the purpose of this lab is to observe principles of homeostasis and osmosis in action. The results of this experiment showed that eggs placed in a 4 M sucrose solution lost mass over time and had the greatest percent difference in mass compared to the eggs in other solutions‚ with the 4 M egg having an average of -25.13% difference in mass. The 0.0 M solution egg only had a 12.28 average percent difference in mass‚ the 0.5 M egg with 10.39%‚ and the 1 M egg with the least

elimination of urine. Formation and elimination of the urine is important for the human body because it contains nitrogenous wastes of the body that must be eliminated to maintain homeostasis. The urinary system is important for keeping the internal environment of the body clean. This particular system maintains proper homeostasis of water‚ salts and nitrogenous wastes (Iqba‚ 2010). There are four major organs that make up the Urinary system. The four major organs are the kidneys‚ ureters‚ urinary bladder

Bio 104-03 Lab #3- Acids Bases‚ and Buffers 1. An acid is a substance that releases hydrogen ions as they desolve in water and ranks lower than seven on the pH scale. An example of an acidic substance is lemon juice. A base is a substance that accepts hydrogen ions and ranks higher than seven on the pH scale. An example of a base substance is hand soap. A neutral substance ranks a seven on the pH scale and has equal concentrations of H+ and OH-. An example of this is pure water. Electrolytes

life. I was sitting on top of Mount Everest for what had been three days now. I was cold scared and had little food‚ I was doing my best to stay warm but I wouldn’t do it alone my body had to help out. My body was doing its best to maintain homeostasis. The brain is using my spinal cord to shake my body‚ (shivering) so that I may stay moving and stay somewhat warm. At this point I’m terrified almost certain that I wasn’t going to survive. Another cold

illness. Walter Cannon used it in 1926 to refer to external factors that disrupted what he called homeostasis. Homeostasis is a concept central to the idea of stress. In biology‚ most biochemical processes strive to maintain equilibrium‚ a steady state that exists more as an ideal and less as an achievable condition. Environmental factors‚ internal or external stimuli‚ continually disrupt homeostasis; an organism’s present condition is a state in constant flux wavering about a homeostatic point
