Here are some diseases which are caused by gene mutations:- 1)Cystic Fibrosis:- Cystic fibrosis is a single gene mutation. This disease is related with secretory glands of the body like sweat and mucus. This is a hereditary disease.
Rime ice forms and accumulates on the leading edge of exposed parts, producing rough, irregular formations. FROST. âFrost is formed through the process of sublimation; ice crystals form when water vapor contacts a cold surface. Frost may form in the air and on the ground. When aircraft descend through a cold layer of air into a layer of warm, moist air, frost formation is possible. It may also form at flight level when aircraft pass from a sub-freezing air mass into a moist and slightly warmer air mass. On the ground, frost may form during a clear night with subfreezing temperatures.
Frost forms in much the same way as dew forms. Frost usually forms when a surface cools through loss of infrared radiation to a temperature which is colder than the dewpoint of the air next to the surface, AND the temperature of that surface is below freezing (32 deg F, or 0 deg.C).The source of this moisture is water vapor contained in the air.he heaviest coatings of frost usually do not occur at the coldest temperatures because very cold air can not hold very much water vapor. Instead, thick deposits of frost usually occur when the air temperature is close to 32 deg.
