1.)Coral reefs are busy underwater ecosystems. Some people call them the “rainforests of the sea.” The corals look like rocks but actually are animals. They have hard calcium carbonate skeletons like clams. They form a base for lots of other organisms to live. You’ll find crabs, sea stars, worms, clams, sponges, jellies, sea turtles, and lots of fish. Coral reefs are complicated and very fragile. They are easily affected by pollution.
2.) Tropical rainforests are near the equator where it’s almost always warm and wet. These are the key ingredients for making lots of lush plants and trees. Half of the world’s plants and animals live in tropical rainforests. It’s a very busy ecosystem with many kinds of plants, animals, fungi, and microscopic organisms. Many of them live here and nowhere else.
3.) In the world’s many deserts, there is very little rain. The land is very, very dry. Here, living things have creative ways of finding and saving water. Cactuses are very good at storing water. They can live without rain for months. The kangaroo mouse lives in the Nevada desert. It rarely drinks water. It can get its water from the food it eats.

Answer:
False
Explanation:
When the proteins change its conformation and attain a 3-Dimensional structure therefore they form a pore or cleft like structure. This cleft is formed by the different part of the amino acid sequence which helps from the weak bonds between the proteins to the substrate.
The substrate gets attached to the active site and the enzymes lower down the activation energy of the reaction and thus proceeds the reaction at a faster speed.
Since the active site is the site for the attachment of the substrate and not other enzymes therefore False is the correct answer.
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.
