Between 10% to 20% of heavy drinkers will develop cirrhosis of the liver (NIAAA, 1993). Acetaldehyde may be responsible for alcohol-induced fibrosis by stimulating collagen deposition by hepatic stellate cells.
Houseflies pass through four distinct stages: egg, larva, pupa and adult. The life expectancy of a housefly is generally 15 to 30 days and depends upon temperature and living conditions. Flies dwelling in warm homes and laboratories develop faster and live longer than their counterparts in the wild.
It is like a brown object in which larvae becomes an adult fly. This cycle takes 18 days, approximately three weeks. The housefly live according to the surrounding temperatures. If the climate is very hot, they live up to two weeks only. In winters, when the temperature is very low, these flies live for more than two months.
