Explain the relationship between genetic change and adaptation.

Natural selection is the process by which adaptations occurs over a series of generations, while mutations can cause instant adaptations. A mutation is an alteration of the DNA sequence. Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment.

does this help?

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.
