Answer:

Answer is A

Explanation:

As we know , for constant velocity we get a straight line.

The formula for this problem is s = vt which is similar to a straight line formula like y = mx + c.

If we put here c = 0 we get the formula for distance and velocity.

So the answer is A.

leonid [27]

Answer: C solar energy

Solar energy has the greatest  impact on primary productivity.

Explain what a concentration gradient is and what it means for a molecule to diffuse down its
MArishka [77]

Answer:

Diffusing the gradient ensures that most of the molecules in high concentration zone will wind up in the previously low concentration by the spontaneous movement of small molecules.

Explanation:

A gradient of concentration is the difference between in concentration of one place / area substance to different area. Having a molecule flow down its concentration gradient means moving the molecules from hypotonic areas to the concentration hypertonic areas

Diffusing the gradient ensures that most of the molecules in high concentration zone will wind up in the previously low concentration by the spontaneous movement of small molecules.
