Dry hopping refers to adding hops to the fermenting beer and letting them soak in it for a period of no less than 10 days. For the typical five-gallon batch of home brewed beer, one to four ounces is the appropriate range of hops to use.
Snakes shed their skin to allow for further growth and to remove parasites that may have attached to their old skin. As a snake grows, its skin becomes stretched. Unlike human skin, a snake 's skin doesn't grow as the animal grows. Eventually, a snake 's skin reaches a point where further growth is not possible.
In very hot weather (say, over 100 degrees F), they can easily overheat and die if they cannot find a cool place (such as a shaded rock or bush). This is called behavioral thermoregulation: the snake can't internally moderate its body temperature, but it selects sites that will help it do so externally.
