Answer to Question 1

ANS: D
Gas gangrene is a special type of gangrene caused by infection of injured tissue by one of many species of Clostridium. Fat necrosis is cellular dissolution caused by powerful enzymes, called lipases, that occur in the breast, pancreas, and other abdominal structures. Wet gangrene develops when neutrophils invade the site, causing liquefactive necrosis. Gangrenous necrosis is due to death of tissue and results from severe hypoxic injury.

Answer to Question 2

ANS: B
In apoptosis, cells are programmed to die. Apoptosis is not associated with cell atrophy, regener-ation, or aging.
