Question

All living cells must maintain homeostasis or internal stable conditions in order to survive. Which of the following processes would best help a cell to maintain these conditions
(SC.6.1.142)
АО
using energy
BO
creating DNA
using carbon dioxide
creating water molecules

Answer 1

Answer:

None of the options provided is correct but some are close

Explanation:

One of the ways in which a cell maintain homeostasis is by regulating what goes in and out of the cell through the cell membrane (which is a semi-permeable barrier). The amount of water is highly regulated by the cell in this case so as to regulate osmosis (movement of water molecules from a region of higher concentration to a region of lower concentration). Other substances regulated are oxygen and carbon dioxide.

NOTE: The cell does not create water molecules neither does it use carbon dioxide to maintain homeostasis, it rather regulates these two compounds.
