<span>Natural selection is a process by which organisms that are better adapted to their environment tend to C. evolve new traits. Evolution is a process of change through time. There are several mechanisms of evolution, such as natural selection, mutations, migrations, and genetic drift. Natural selection is the mechanism by which species adapt to their environment to increase their chance of survival and reproduction. It can result in progress and cause some organisms to evolve new traits they need. </span>
The cytoskeleton is in both prokaryotes and eukaryotes.
Answer: prokaryotic cells have no nucleus, no organelles and a small amount of DNA. Eukaryotic cells do have a nucleus, along with many organelles, and more DNA.
Explanation:
Polar bodies are considered byproducts of oogenesis. They are lacking cytoplasm and are much smaller than a regular egg cell. Typically they disintegrate after meiosis. It is unlikely for the resulting zygote to become a healthy embryo because the polar body was never meant to get fertilized. Therefore it is most likely lacking nutrients, and does not have the necessary resources for a healthy baby to develop.
