Prenatal virilization. In the prenatal period, virilization refers to closure of the perineum, thinning and wrinkling (rugation) of the scrotum, growth of the phallus, and closure of the urethral groove to the tip of the penis. In this context, masculinization is synonymous with virilization.
[QUOTE=Greatnorth;481595]Well, usually I wait till there's a good 3-4 foot of snow because you don't want your skis to touch the dirt/ground or whatever isn't snow. Snowmobiles are made to operate on snow and that's all they should do. Really 3-4 feet of snow until you go snowmobiling??? They open the trails around here when roughly 6-7 inches of snow are on the ground. Never had a problem running my sleds in 6 inches of snow or more.
How many inches of snow equals one inch of rain? On average, thirteen inches of snow equals one inch of rain in the US, although this ratio can vary from two inches for sleet to nearly fifty inches for very dry, powdery snow under certain conditions. Is it true a person loses most of his body heat through his or her head? Yes, it's true.
