Answer:
For growing bacteria it is necessary water, a source of carbon and nitrogen, some inorganic salts.
Explanation:
There are plenty of kind of bacteria, even, all of them need water to dissolved their nutrients and to remove the wastes outside of the bacteria body. The source of carbon could be carbon dioxide for some bacteria that do not need a lot of it. In the other hand, there are other bacteria that are feed based on glucose, fructose or another carbohydrate.
Nitrogen sources normally come from air as gaseous element or some inorganic salts like nitrates.
Other bacteria need specific elements like phosphorous, sulfur, zinc, copper, etc.

Answer:
Repolarization
Explanation:
Repolarization refers to the phase during which the resting potential is restored after depolarization. This means that the inside of the axon membrane becomes negative again compared to the outside.
Repolarization is obtained by the functioning of K+ ion channels. The opening of K+ ion channels allows the K+ to move outside of the axon. Movement of positively charged ion (K+) outside of axon makes the inside negative again and the resting potential is restored.
Answer:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.
