Answer:
A
Explanation:
mtDNA is inherited from the mother of a child, this is because mitochondria are in the cytoplasm and the father's gamete (sperm cell) contributes very little or no cytoplasm to the zygote. We know that mitochondrial Eve came from Africa because the mutations in the mtDNA occurred before the <em>out-of-Africa dispersal</em>.
Density and distribution of stars are directly affected when the change occur in the size of the circle.
<h3>Effect on density </h3>
The density and distribution of "stars" changed as the circle gets larger because when the circle gets larger, its volume increase which results in the decrease in the density. The distribution of stars also changed due to more space or volume present in the medium.
<h3>Distribution</h3>
If the universe is more condensed, then the stars are more closer together but when the universe is more expand then the stars are present farther away from each other so we can conclude that density and distribution of stars are directly affected when the change occur in the size of the circle.

2 .The genetic makeup of an organism is known as its genotype. The genotype refers to the set of traits found within the cells of living organisms. These traits, known as the genetic code, are passed from one generation to the another during cell division and reproduction.
