If you know that wrinkles are caused by muscle contractions around the eye, and you know the effect of Botox on acetylcholine release (CQ3) and, therefore, muscle contraction (CQ4), what is the effect of Botox on wrinkles?
A. Induces wrinkles by inducing acetylcholine release, and, therefore, contraction of muscles around the eye.
B. Inhibits wrinkles by preventing acetylcholine release, and, therefore, preventing contraction of muscles around the eye.

2a. Creatine supplements are touted as a way to increase energy to muscle and therefore be stronger and faster.Based on what you know about creatine, would creatine be more effective in helping enhance performance for a sprinter or for a marathon runner? Why? b. Shortly after beginning to take creatine, users’ muscles increase in mass, but this is simply due to increased water in the muscle. Why would taking creatine supplements lead to more water in muscles? (Hint: Creatine is...
