The sugar and other organic molecules are transported through the plant by means of a special layer of tissue called phloem. By this means, nutrients can be moved from the photosynthetic site (the source) to the place where the sugar is being used (the sink) whether it is up or down the stem of the plant.
The cells that are transformed into plasma cells with the influence of cytokines are T-Helper cells. It is a very important cell in our immune system and it is used to activate antibodies that could help destroy microbes and pathogens entering the body. They are commonly produced in the bone marrow.

Answer:
The correct answer would be "The percentage of dark brown sea lions will increase, and the percentage of light brown sea lions will decrease".
Natural selection refers to the natural phenomenon by which organisms which are better adapted to the changing environment tend to survive and reproduce more as compared to the organisms which are less adapted.
As aquatic environment make dark brown sea lions more reproductively successful thus, the offspring of dark brown sea lions would have better chances to reach the reproductive age.
Hence, with the percentage of dark brown sea lions would increase and that of light brown sea lions would decrease.
As stated, the enzyme glucose-6-phosphate dehydrogenase helps red blood cells function properly. Therefore, G6PD deficiency can cause hemolytic anemia characterized by having low levels of red blood cells. The <span>parasite that causes malaria does not survive well in G6PD deficient cells since they appear to have resistance against the disease. </span>
