Fill the chart. First one is already done. Btw this is Edge cell structure project sheet.

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.

in tropical forests it typically is hot with a lot of rain. when what is hot, it starts to evaporate and turn into water vapor.
