<em>The correct option is D) It does nothing to protect the atmosphere over Antarctica.</em>

lora16 [44]

Answer:

The answer is A) You would find 46 chromosomes in a Haploid cell and B.) You would find 23 chromosomes in a Diploid cell.

Explanation:

A human haploid cell, such as a skin cell, is a complete unit. It is capable of duplicating itself and the new cell has exactly the same number of chromosomes, which is 46.

A human diploid cell, such as a human egg cell, has half the number of chromosomes, which is 23.

Hope this helps!! Have an Awesome day!!! :-)
