Rod photoreceptor cells are responsible for vision in dim light. The figure shows the pathway through which a rod photoreceptor cell senses light. Predict whether the following mutations will result in a) night blindness (poor or no eye-sight in dim light), or b) prolonged response to a short light flash. Hint: Blocking the activation pathway will result in night blindness; whereas, blocking the inactivation pathway will result in prolonged response to a short light flash. Rhodopsin is mutated and permanently inactive [1] The cGMP phosphodiesterase is mutated and permanently inactive [2] Regulator of G-protein signaling protein is mutated and permanently inactive [3] Rhodopsin kinase is is mutated and permanently inactive [4] The guanylyl cyclase is is mutated and permanently inactive [5]

Each part of this question will be worth 3 points. State whether the following questions are “true” or “false.” You must explain your reasoning to receive full credit. Please record your answer by typing the letter that corresponds to the part you are answering. For example, if you are answering part a, type “A) your answer.” A binding price ceiling must be set above the equilibrium price. 写下错误答案。 Consider a $5 unit tax imposed on a market.

A price ceiling, such as rent control, creates a shortage. 写下错误答案。 Under a tariff, prices of imported cars increase but prices of domestically produced cars do not change. 写下错误答案。
