This is the transfer of characteristics from parent to offspring.

Heredity

Explanation:

Heredity explains how characteristics (traits) are transmitted from parents to offsprings, making each offspring to resemble their parents since characters such as eye colour, skin colour, blood group etc are transferred from the male and female parents into the body of the new offspring.

Thus, heredity shows that an offspring inherit characterictics from each parent.

not only is it colder, it also becomes darker, less salty, and more dense.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
