The sediment was being deposited in a new location. <u>Option D.</u>

<u />

Chemical weathering describes the process by which chemicals in rainwater change the minerals of rocks. Carbon dioxide in the air dissolves in rainwater, making it slightly acidic. Weathering describes the deterioration or dissolution of surface rocks and minerals.

Water Ice Salt Plants Animals Changes in temperature are all factors in weathering. When rock is mined, rock fragments and minerals are carried away through a process called erosion. When flooding occurs streams erode Also the same amount of sediment builds up creating a new equilibrium. Plants and animals' air and water are the main causes of weathering.

PLEASE HELP. I REALLY NEED THIS!!!!
Viefleur [7K]

Answer:

In nature, populations are usually evolving. The grass in an open meadow, the wolves in a forest, and even the bacteria in a person's body are all natural populations. And all of these populations are likely to be evolving for at least some of their genes. Evolution is happening right here, right now!

To be clear, that doesn't mean these populations are marching towards some final state of perfection. All evolution means is that a population is changing in its genetic makeup over generations. And the changes may be subtle—for instance, in a wolf population, there might be a shift in the frequency of a gene variant for black rather than gray fur. Sometimes, this type of change is due to natural selection. Other times, it comes from migration of new organisms into the population, or from random events—the evolutionary "luck of the draw."

I hope this helps a little bit.

Please answer 5&amp;6. Thank you.
erastovalidia [21]

Answer:

5. The correct answer would be an option A. ova

Note: I assume that all the samples are of human origin.

DNA (deoxyribonucleic acid) content of somatic cells of humans consists of 46 chromosomes or 23 pairs of chromosomes. Gametes (sperm or ova) are haploid cells produced by the process of meiosis and contain half the number of chromosomes found in parent cell. Hence, they contain 23 chromosomes.

6. The correct answer would be an option J.

Sperm formation or spermatogenesis is the process by which spermatozoa (haploid gamete) is produced from germ cell with the help of meiotic division.

Meiosis results in the formation of four haploid (n) cells from single diploid (2n) parent cell. Here, 2n is given as 8 so, n would be equal to 4.

Meiosis I results in the formation of two secondary spermatocyte cells (both haploid or 4 chromosomes in this case) from single primary spermatocyte (diploid or 8 chromosome in this case).

Both the secondary spermatocytes undergo meiosis II to produce 4 spermatids (each haploid or 4 chromosome in this case). Spermatids differentiate and mature into spermatozoa.

How did robert hooke contribute to the cell theory?
Blizzard [7]

Answer:

<em>Read explanation.</em>

Explanation:

Robert Hooke defined what a cell, in other words, he gave that name to what we now know as a "cell".

How he came up with that name is simple, and doesn't involve science or biology itself. All happened when he was looking to a sample of oak bark, and saw this tiny enclosed structures, that reminded him of a cell.

Hope it helped,
