Cell walls are supporting structures that help the plant to have a fixed shape and protect it from injury. Other than that, it helps to keep the plant turgid so that it can stay firm and upright. Because when it enters a high water potential solution, as water moves in, the water exerts turgor pressure on the cell wall and the cell wall thus exerts an opposing pressure to keep water out. Hence cell wall is needed for the plant.
On the other hand, animal cells do not need to keep the structures, as they have the skeletal system to protect the organs and cushion them against any
external injuries.

Answer:
B) a higher protein to lipid ratio.
Explanation:
The cell membrane of eukaryotes is known to be a phospholipid bilayer with embedded proteins. This implies that the first tube will contain a higher amount of lipids.
The membrane of the mitochondria is slightly different from the cell membrane in which its protein to lipid ratio is higher, containing a large number of integral proteins.
A compound that has Carbon and Hydrogen
Answer:
b. Some carbon dioxide will move from chamber A to chamber B.
Explanation:
The two chambers are separated from each other by a separator that exhibits the properties of the cell membrane. It means that the separator film is semi-permeable in nature. The concentration of CO2 in the chamber A is 80%. This is relatively higher than its concentration in chamber B (20%). The concentration gradient will drive the passive diffusion of some of the CO2 from chamber A to chamber B so that the concentration becomes equal in both the chambers.
Answer:
Reactivity.
Explanation:
I’m sorry, I don’t really know how to explain this. I just have it memorized. Sorry I couldn’t help more, best of luck!
