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.
The simple answer is that snakes shed their skin because they are just like all other animals. All animals shed their skin â even you! In mammals, especially humans, this is an ongoing process that's rarely noticed. Skin shedding in reptiles is different. Instead of an ongoing process, reptiles shed skin periodically.
