Ap Biology Midterm |125 Questions| With Correct Answers.

Antidiuretic hormone (ADH) is important in maintaining homeostasis in mammals. ADH is released from the hypothalamus in response to high tissue osmolarity. In response to ADH, the collecting duct and distal tubule in the kidney become more permeable to water, which increases water reabsorption into the capillaries. The amount of hormone released is controlled by a negative feedback loop. Based on the model presented, which of the following statements expresses the proper relationship between osmolarity, ADH release, and urine production? {Ans: As tissue osmolarity rises, more ADH is released, causing less water to be excreted as urine.}A human cell in prophase of mitosis can be distinguished from a human cell in prophase I of meiosis by the presence of {Ans: paired homologous chromosomes in the meiotic cell}An increase in the rate of oxygen production by algae would be accompanied by a comparable increase in the rate of production of which of the following substances? {Ans: C6H12O6}Figure 1. A simplified model of the glucocorticoid receptor signaling pathway Which of the following statements best predicts the effect of a mutation that results in a loss of the glucocorticoid receptor's ligand binding function? {Ans: The glucocorticoid receptor will remain
