Identify the following structure:
nika2105 [10]

Answer: I included a labeled graph of both a plant cell and an animal cell. I don't know if you needed an explanation of what they do, too, but I'll include it anyway.

Explanation:

The Cell Membrane, or plasma membrane, provides protection for the cell. It also transports substances in and out of the cell.

The Cell Wall (only plants) provides the structure for a plant, as well as added protection.

The Mitochondria are the powerhouse of the cell, providing energy for our cells to do their work. They produce a small molecule called ATP (adenosine triphosphate), where the energy is stored and sent to where it is needed.

The Lysosomes are the waste facilities of cells. They breakdown excess or worn-out cell parts, destroy foreign or invading bacteria, and digest macromolecules (carbs, lipids, proteins, and nucleic acids)

What is a likely result of crossing over during meiosis I?
shusha [124]

Given what we know, we can confirm that the result of crossing over during meiosis I gives rise to new combinations of genes in the gametes at the end of meiosis.

<h3>What is meiosis?</h3>

It is the process of cell division that occurs in the gonads for the production of gametes that gives four haploid cells. During the crossing over, what will happen is that the homologous chromosomes exchange parts and new combinations are given for the gametes.

Therefore, we can confirm that the result of crossing over during meiosis I gives rise to new combinations of genes in the gametes at the end of meiosis.
