The answer is viruses change their form when the immune system knows how to kill it and thats how they trick the immune system and viruses are much smaller than bacterias
Hypothermia occurs when a low internal body temperature interferes with the body's ability to regulate vital processes, such as metabolism and the heartbeat. One risk for hypothermia is getting wet, which vastly increases heat loss in the cold.
The right answer is the large intestine.
The colon is part of the digestive system. Also called the large intestine, the colon follows the small intestine and forms the last part of the digestive system. It consists of several parts:
the caecum (from which leaves the vermiform appendage);
the ascending colon (right);
the transverse colon;
the descending colon (left);
the sigmoid colon;
and the rectum.
Its role is mainly to eliminate waste, absorb water, maintain the water balance and absorb certain vitamins. Chyle from the small intestine lacks almost all (90%) of the nutrients already absorbed by the digestive system. Chyle mixes in the colon with mucus and intestinal bacteria to form the feces. Bacteria capable of digesting the fibers form new molecules that the colon is then able to assimilate.
