How can the two chromosomes that make up a homologous pair differ? they can contain different alleles for the same trait. they can contain genes that code for different traits. they can contain the same genes in different orders. they cannot differ in any way when homologous.

The small molecule cyclic amp (camp) takes about 0.2 second to diffuse 10 μm, on average, in a cell. suppose that camp is produced near the plasma membrane on one end of the cell; how long will it take for this camp to diffuse through the cytosol and reach the opposite end of a very large cell, on average? assume that the cell is 200 μm in diameter.

How do disease caused by bacteria and disease caused by viruses react to antibiotics?

Genetic orders can result when sister chromatids fail to separate properly during which phase is this problem most likely to occur
