Vlada [557]

Answer:

  the very long river

Explanation:

Larger rocks tend to settle out of the water flow sooner than smaller rocks do, so the rocks remaining at the end of a very long river would tend to be very small. A very short river may still be carrying somewhat larger rocks.

The very long river probably drops the smallest rock pieces near the ocean.

_____

Perhaps the implied assumption here is that a very short river will have a higher gradient than a very long river. Another assumption is that rocks are picked up nearer the headwaters, and the gradient decreases with distance.

If both rivers end at a waterfall into the ocean, they may very well carry the same sort of rock size distribution. If the short river traverses muddy terrain, and the longer river traverses rocky terrain, the answer may be reversed.

- Are living things only the product of their DNA? Why or why'not?
Darina [25.2K]

Answer:

No, since DNA does code for certain traits, others are introduced or changed by the environment. For example, some adaptations are not coded in DNA, such as dying hair. According to the gene, hair is to be black, for example, but it can be changed to look pink. Another example is when a person is first born. When they are, some bacteria enter the system of the baby --- mostly good. Then the baby's gut will be different, and the bacteria in the gut are not coded by the DNA. So, living things are not only the product of DNA, as there are extraneous factors that affect living things as well.

Explanation:

Phew, that was long! Hope this helps (:

Hello,

I hope this helps!

chromosomes that carry genetic information align in the equator of the cell before they split off into two daughter cells

Explanation:

During metaphase, the chromosomes that carry genetic information align in the equator of the cell before they split off into two daughter cells with identical genetic material. Metaphase is the third stage of mitosis, which is a phase of the cell cycle where chromosomes in the nucleus are divided between two cells.
