Exoskeleton-external skeleton composed of calcium carbonate and chitin
Endoskeleton-body's internal system made of hard mineralised components.

Answer:
a) Most alcohol is metabolized in the small intestine.
b) Food in the stomach slows the absorption of alcohol.
c) Alcohol inhibits the release of anti diuretic hormone, which can lead to dehydration.
Explanation:
About 80 % of alcohol is absorbed by the stomach while 20 % of alcohol is absorbed by stomach. Food materials such as lipids etc slow down alcohol absorption by the intestine because the valve that is present between stomach and small intestine is closed if food is present in the stomach. Alcohol decreases the release of anti diuretic hormone, so low water is removed from the body and reduce dehydration.
