20-inch roof snow depth x 1.25 Ibs/sq ft = 25 Ibs per sq ft of roof snow load NOTE: Any ice build-up on the roof would need to be added to this formula. Add 5.2 Ibs for each 1-inch of ice depth. Notes: 1. Structures constructed in McCall with building permits are designed for 120 Ibs/sq ft minimum roof snow load. Older roofs may be of concern and may not meet this minimum roof snow load. 2. Until recently, manufactured homes were designed for a roof snow load of 30 Ibs/sq
-Eric Lai. Cells reproduction rate Cells reproduction rate is pretty fast. Different cells in different parts of the body reproduce in different rates. The skin cells reproduce really fast because the skin cells takes more damage then any other cells.If skin cells don't reproduce as fast as now, then your skin won't be able to heal as fast and you would get hurt easier. Skin cells reproduce about one million cells per second. That is how your skin heals fast.If you keep bothering your skin, then the injured spot won't heal as fast.f skin cells don't reproduce as fast as now, then your skin won't be able to heal as fast and you would get hurt easier.

Mitosis. The cell division process that produces new cells for growth, repair, and the general replacement of older cells is called mitosis. In this process, a somatic cell divides into two complete new cells that are identical to the original one.Human somatic cells go through the 6 phases of mitosis in 1/2 to 1 1/2 hours, depending on the kind of tissue being duplicated.owever, the process varies with the kind of cell. Somatic, or body cells, such as those that make up skin, hair, and muscle, are duplicated by mitosis. The sex cells, sperm and ova, are produced by meiosis in special tissues of male testes and female ovaries.
