Competition is central to the theory of natural selection. Why does competition occur? Organisms typically produce too many offspring, and resources are limited. All organisms, including prokaryotes and eukaryotes, use essentially the same genetic code.

Explanation:

All organisms, including prokaryotes and eukaryotes, use essentially the same genetic code.

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.
