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.

All human body cells contain 46 chromosomes (two sets of 23 chromosomes). Only the gametes (i.e., the sperm & eggs) contain 23 chromosomes (one set of 23 chromosomes) because two gametes combine to form a new person with 46 chromosomes in his body cells.Body cells grow and reproduce by the process of mitosis.For each human body cell (with 46 chromosomes) that undergoes mitosis, two identical human body cells (with 46 chromosomes) are produced. Gametes (i.e., sperm & eggs) are produced by meiosis.For example, in the testes of a man, for each body cell (with 46 chromosomes) that enters meiosis, four sperm (with 23 chromosomes) are produced. (Meiosis is a two part process, thatâs why four gametes are produced, not just two).nly the gametes (i.e., the sperm & eggs) contain 23 chromosomes (one set of 23 chromosomes) because two gametes combine to form a new person with 46 chromosomes in his body cells.
