The following facts that support the endosymbiotic hypothesis are: Mitochondria and chloroplasts have a single circular chromosome.Mitochondria and chloroplasts divide by mitosis. Mitochondria and chloroplasts have 70S ribosomes. Mitochondria and chloroplasts have histones to organize their chromosomes. Mitochondria and chloroplasts have peptidoglycan in their cell walls.

Explanation:

1.Mitochondria and chloroplasts have a single circular chromosome.

2.Mitochondria and chloroplasts divide by mitosis.

3.Mitochondria and chloroplasts have 70S ribosomes.

4.Mitochondria and chloroplasts have histones to organize their chromosomes.

5.Mitochondria and chloroplasts have peptidoglycan in their cell walls.

age range would be the answer

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
