<span>if a molecule is too large it cannot pass. also it depends on the concentration of a specific substance inside the cell. similarly, if a molecule is polar it cannot penetrate the phospholipid bilayer.
there are proteins that work as channels and pumps that allow these molecules to pass

Answer:
A. Areas at high elevations have cooler temperatures.
Explanation:
Areas with high altitude or elevations have cooler temperatures because <u>air molecules are less in the air at high elevation that decreases the gas pressure leading to low temperature.</u>
Earth's surface absorbs heat and diffuses it into the atmosphere that warms up the earth's surface. Layers of the atmosphere in higher-altitude areas diffuses less heat and maintain the low temperature.
Hence, the correct option is "A. Areas at high elevations have cooler temperatures."
