CAN SOMEONE PLEASE HELP ME ON BOTH QUESTIONS ASAP

A, A

Explanation:

Rivers pick up and move sediment downstream creating landforms.

I believe it is A, not 100% sure. However. heavy rain creates runoff that would push pollution into the rivers and ponds.

Question 1.  (a)

Question 2. (a) (But I'm not sure about it, I think it can also be D)

Explanation:

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
