Biology

Marina CMI [18]3 years ago
3 0

Answer:

D) Even a slight reproductive advantage will eventually lead to the elimination of the less well adapted of two competing species.

Explanation:

The competitive exclusion describes relationship between two species that compete for the limiting sources, and cannot coexist. It is enough for one species to have slightly advantage to be dominant over the other. As a consequence, other species (the weaker one) will be extincted (shift to a different ecological niche).

What happens in animal cells when mineral concentration is high and low in solution
slamgirl [31]

Answer:

Diffusion occurs when there is movement of minerals from an area of higher to lower concentration, till equilibrium is obtained.

Whereas Osmosis is the movement of solvents rather then the solute, from a solution of lower to a solution of higher concentration with the help of semipermeable membrane.

Explanation:

Diffusion is the movement of substances from area of higher concentration to an area of lower concentration of minerals, which mainly results in animal cells. Whether solute or solvent, diffusion occurs for both. Diffusion does not requires any semi permeable membrane. Diffusion occur in all state of matter, that solid, liquid and gas, whereas osmosis occurs only in liquid state. Osmosis requires semipermeable membrane and rate of which is related to concentration of solute dissolution in solvent medium. Only movement of solvent medium takes place. Classical example of osmosis is exhibited by cell membranes of animal cells. On the other hand diffusion is the spreading of perfume or fragrances to the external air.
