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.
Quick Answer. From egg to adult, house flies live anywhere from two weeks to one month. A female fly lays 75 to 100 eggs at a time. The eggs hatch a day later into tiny, legless worms called maggots. The maggot stage lasts 14 to 36 hours.
