Answer:

B

Explanation:

So lets go over facts of mieosis and mitosis:

Meiosis is sexual reproduction

Mitosis is asexual reproduction

Meiosis in animals is how they reproduce

Mitosis in animals is how they regenrate their cells

Mitosis copies the orgninal cell.

Meiosis mixes a male and female egg and sperm to form a zygote

Ok, knowing this. We can find our answer.

Since we know meiosis is sexual, and mitosis asexual, we can get rid of C.

We also know that meiosis is in animals, and so is mitosis, so we can get rid of A.

Finally we can get rid of D, since we know due to the male and female genetics(and through the swapping of chromesomes during prophase)that genetic variation occurs in meiosis, but since mitosis copies a single cell, it is not genetically varient.

<u>So the answer must be C, which states that Mitosis has genetically identical cells, while mieosis does not. </u>

Hope this helps! ;)

The atomic mass of an element is equal to the:
arlik [135]

The answer should be the third option "number of protons and neutrons." The atomic mass of a element is equal to the amount of protons, and neutrons added together in that element. So for example if we are trying to find the atomic mass of hydrogen you would add the total amount of protons and neutrons together to find it's mass although it doesn't equal the exact amount of it's mass but it's close.

Hope this helps.
