Answer:
Obviously, such rocks transmit only small quantities of water and are poor aquifers. By comparison, rocks such as fractured sandstones and cavernous limestone have large connected openings that permit water to move more freely; such rocks transmit larger quantities of water and are good aquifers.
Explanation:
The correct statement is :
Excretory system excretes waste materials from the body and is very important for homeostasis.
Answer: True
Explanation:
The given statement is true that the waste material that is produced inside the body needs to be excreted out.
This is an important part o the homeostasis that the waste should be excreted out of the body on time. This helps in maintaining equilibrium inside the body.

So, the correct answer is True.
Answer;
-The rate of the reaction;
The presence of an enzyme affects only the rate of the reaction.
Explanation;
-Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
-Additionally, the rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction. However, enzymes become saturated when the substrate concentration is high.
