A) Increase its size.
B) Engulf another cell.
C) Divide into as many small cells as possible.
D) Adhere itself to another cell.
E) Move around quickly in its environment.

Quizplus · Accepted Answer

By dividing into as many small cells as possible, each individual cell will have a higher surface area to volume ratio, which allows for a greater rate of exchange with the environment. This is because a higher surface area allows for more interactions with the environment, while a lower volume reduces the amount of chemical activity needed to maintain cell function. Increasing size, engulfing another cell, and adhering to another cell do not necessarily increase surface area to volume ratio, while moving around quickly may require more energy and chemical activity.
