an increase in Earth's temperature is global warming. Global warming affects the ice caps. therefore, an increase in temperature will melt the ice caps

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.
