Atransport process that does require direct input of energy in the form of atp can be described as _

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.

i do believe the correct answer would be the third one. location c, because earth is tilted away from the sun at this time

hope this

to this answer it would be edge enhancement
