In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.

Cellular respiration is the process by which glucose is transformed into ATP. -- It uses oxygen and gives off carbon dioxide and takes place in the mitochondria of the cells. -- It helps maintain homeostasis by transforming energy that can be used to do cellularwork.
The correct answer is B.
On this graph we can observe the workings of the stabilizing selection. Stabilizing selection tends to favor the average phenotype and eliminate the extremes. Essentially, this means that the natural selection is selecting the mean value of a trait as optimal. In our case, the mean weight of newborns is selected as optimal, because newborns born with less weight can be too weak to survive and the ones that have too much weight (are too big) can hurt the mother during birth.
