These winds are opposite from each other. While valley breezes occur when the warm air rises up the sides, warm air in a mountain breeze will rise up the middle.
The correct answer is: A) The polarity of membrane phospholipids
Factors that affect membrane permeability are
1. Chemicals :
Some of the organic solvents such as chloroform and ethanol can dissolve the membrane and thus, destroy the selective permeability of the membrane.
2. Temperature :
Too high temperatures denature the protein that are in the structure of the membrane destroying its selective permeability. On the other hand, too low temperature slows down molecule movements and the permeability decreases.
3. Cholesterol:
Increases the permeability by reducing the barrier formed by phospholipids’ heads
4. The saturation of hydrocarbon tails in membrane phospholipids:
Saturated fatty acids decrease permeability of the membrane because they get very close together, which makes it harder for the molecules to pass through.
