Kile should know the answer because of the morphology (part of biology that studies the estructure and the form of something). The plant cell presents a rectangular form, while the animal's cells presents a round form.
There are other main differences. As their parts and the size. Before I explain that remember that a cell can be of two types eukaryotic (cell with nucleus) and prokaryote (cell with no nucleus). In the other they can be neurons, nefrons, etc...
The plant cell contains for example chloroplasts, cell wall and vascuoles; while animal's don't. Both of them have nucleus, cell plants are generally larger than animals. Those are the main differences.
Thankyou.
Sorry for my bad english, It's not my native language.
Answer:
B. separating strands of DNA
<span>This would be an example of a mutation, because the changing of allele frequencies would be a change within the gene itself, which would be a mutation in the DNA. This is evidenced by the fact that there is now a form of human resistance to malaria, due to changes within human DNA itself.</span>
Sexual reproduction is a form of reproduction where two gametes fuse together. Each gamete contains half the number of chromosomes of normal cells. They are created by a specialized type of cell division, which only occurs in eukaryotic cells, known as meiosis.
So i'm gonna say that the answer is..B. helped maintain a slow rate of evolutionary change.
