There are four questions, 30 pts total    You may include diagrams in your explanation. 1. Negative and positive feedback mechanisms are used to maintain homeostasis. Describe one negative and one positive feedback regulations that we discussed in BIO 305. (8 pts)For each negative and positive feedback:What is the variable? (0.5 pt)What is the normal range? (0.5 pt) Which conditions may change the variable? (0.5 pt)How the changes to be detected? (1 pt)What is/are the response(s)? (1 pt)What is the final effect? (0.5 pt)2.   Different types of nervous system are involved in neural regulation, including somatic motor, somatic sensory, autonomic sympathetic, and autonomic parasympathetic nervous systems.  Describe one organ that uses at least two of the aforementioned nervous systems to regulate its functions. (7 pts)Name the organ. (1 pt)Name the functions to be regulated. (2 pts)Name at least two of the nervous systems involved. (1 pt)Describe how each of the nervous systems regulate the organ’s function. (3 pts)3.   Neuroendocrine mechanisms control homeostasis. Describe a homeostatic regulation that involves both neural and hormonal regulations. (7 pts)Name the homeostatic function to be regulated. (1 pt)Name the tissue/organ involved. (1 pt)Name the neural and hormonal factors involved. (2 pts)Describe how each of these neural and hormonal factors regulate the organ / tissue’s function. (3 pts)4.   Different systems (such as the circulatory system, digestive system, respiratory system, urinary system, skeletomuscular system, etc.) cooperatively regulate homeostasis. Describe a homeostatic regulation that involves two or more different systems (except using only the nervous system and the endocrine system). (8 pts)Name the homeostatic function to be regulated. (1 pt)Name the tissue/organ involved. (1 pt)Name two or more systems involved. (2 pts)Describe how each system regulates and how these systems collaboratively regulate this organ / tissue’s function. (4 pts)
