The answer is A. The mutation of the gene was a beneficial
one. It happened in a few individuals
and increased their survival rate. The mutation
was also inheritable hence was passed down generations. The new gene probably altered a protein involved in

deleterious and neutral.
The primary function of the lymphatic system<span> is to transport </span>lymph<span>, a fluid containing infection-fighting white blood cells, throughout the body. The </span>lymphatic system<span> primarily consists of </span>lymphatic<span> vessels, which are similar to the circulatory </span>system's<span> veins and capillaries.</span>
The answer is that this is a organisms/mircocellular prokaryotes and eukaryotes
Explanation:
What your showing me right now on this image is a tree of prokaryotic and eukaryotic organisms through different forms and traits, each prokaryote or eukaryote changes to a more multi-cell type.
Stem cells can differentiate into any type of cell so they can be used to produce/repair nerve tissues. Advantage of using embryonic stem cells is that they are easier to extract than adult stem cells.
