1. What changes occur to your skin as you get older __//**Answer:**//__ The epidermis thins and the amount of callogen in the dermis decreases.

2. The rate of water loss from the skin of the hand was measured. Following the measurement, the hand was soaked in alcohol for 15 minutes. After all the alcohol was removed from the hand, the rate of water loss was again measured. Compared with the rate of water loss before soaking the hand of alcohol, what difference, if any, would you expect in the rate of water loss after soaking the hand in alcohol?

__//**Answer:**//__ I would say that the rate of water loss from the hand soaked in alcohol would be greater because the alcohol takes away the oils. The oil was blocking the water from coming out so as soon as it is removed, the water starts to come out more easily.
