The percentage is 89%. Took this test and got the same exact question.
By controlling what enters and leaves a cell, the cell membrane A) aids in maintaining homeostasis within the cell. Homeostasis is the process by which organisms maintain life through eating, growing, and living in variable conditions. It would not make sense to answer B) because organisms do not control the homeostasis of their external environment. D) also would not be correct because cell's do not control osmosis in the external environment. The membrane does not control osmosis because osmosis is generally a random process of molecular diffusion whereas the membrane acts in a conscious and controlled way.
I think the molecules that will easily <span>dissolve in water based on polarity not on size would be as follows:
</span><span>CH and small 3 with H OH
</span><span>CH and small 2 with H OH
These molecules would indicate they are alcohols which are definitely soluble in water. Hope this helps. Have a nice day.</span>
The process is Transcription
<span>No change in temperatures between seasons. Tilt is the angle between the direction of positive pole and the normal to the orbital plane. Seasons occur due to the tilt of axis. If there is no or zero degree tilt there will be no season. Season means changes in temperature. the amount of sunlight received remains same throughout the year which causes for no change in temperature and hence no season.</span>
