BIOC32H3 Lecture Notes - Lecture 1: Homeostasis
Document Summary
Physiology: physiology is how the body maintains homeostasis. Homeostasis is the mechanism by which the body maintains a constant environment for all its metabolic functions. Body: a load of compartments pushed inside the skin, e. g. the respiratory system, the digestive system, the circulatory system, etc. All these systems are highly integrated and have intense levels of communication. The compartmentalization of these systems control the uptake and loss of controlled amounts of the right products. When homeostasis fails, we see physiological issues such as fever, nausea, dehydration, etc. The first step would be to create a good hypothesis. A good hypothesis must be testable and logical. Independent variable: a variable that is not dependent on any other variable, and one we can control during the experiment e. q. time, increasing ph of soil, type of food, gender. Dependent variable: a variable that is dependent on another variable that is being tested, e. g. plant growth, rate of decay, etc.
