Answer:
Bacteria Evolution
This process is called Endosymbiosis.
Explanation:
Symbiosis is a relationship in which organisms from two separate species live in a close, dependent relationship. Endosymbiosis (note that endo means within) is a specific type of symbiosis where one organism lives inside the other.
This causes bacteria, mitochondria, and chloroplasts to be similar in size. Bacteria also have DNA and ribosomes similar to those of mitochondria and chloroplasts.
Based on this and other evidence, scientists think host cells and bacteria formed endosymbiotic relationships long ago, when individual host cells took in aerobic (oxygen-using) and photosynthetic bacteria but did not destroy them. Through millions of years of evolution, the aerobic bacteria became mitochondria and the photosynthetic bacteria became chloroplasts.
In the amygdala, which is part of the brain that is linked to fear, and lower activity in the prefrontal cortex.

Answer:
Explanation: The sugar and phosphate group make up the backbone of the DNA double helix, while the bases are located in the middle. A chemical bond between the phosphate group of one nucleotide and the sugar of a neighboring nucleotide holds the backbone together.
Answer:
B- finding new sources of freshwater
Explanation:
To solve the world water crisis we need to conserve water. Finding new sources of water increases the rate of drought, famine and water scarcity in zones. It can also act as a factor of desertification. We need to reduce, reuse and recycle when trying to conserve a resource.
