Answer:
A fixed allele is an allele that is the only variant that exists for that gene in all the population
Explanation:
An increase in the membrane permeability for a solute will result in an increase in the driving force for diffusion of that solute through the membrane. This statement is TRUE.
Surface area and porosity/permeability are the two variables that are most relevant to diffusion via a membrane. Slower diffusion will result from a membrane with less permeability or less surface area, which will obstruct molecule motion. More permeable cells can withstand cold and freezing more easily, but they could also become dehydrated. Living cells are suspended in an aqueous solution, and as the cells move through the solution, ice crystals begin to form in the solution around them, increasing the concentration of solutes outside the cells.

Answer: ONLY CERTAIN SUBSTANCES CAN PASS THROUGH IT
Explanation:
1 only gases and water can pass through it.
2 substances need permission to pass through it.
3 only certain substances can pass through it.
4 substances need carrier molecules to pass through it.
5 ATP is always needed to move molecules across the plasma membrane.
Too much rain can be damaging. But of course, soil along with plants do need water to sustain life.
