Answer: A, Natural selection favors G6PD deficiency as compared to malaria.
Explanation:
We can eliminate B. This is because genetic drifts are changes in genes due to chance. The changes in the genes of the African Americans were not due to chance because there was a cause: malaria.
We can also eliminate C. This is because somatic mutations are mutations that can occur in every cell except the germ cells (sperm, egg), therefore meaning that the mutations that occur cannot be passed onto the offspring.
Answer:
Bronchial pneumonia
Explanation:
The secondary infection is caused during the treatment for any infection or after the treatment. The changes in the immune system is a cause of this infection.

Cell–cell interaction refers to the direct interactions between cell surfaces that play a crucial role in the development and function of multicellular organisms. These interactions allow cells to communicate with each other in response to changes in their microenvironment. This ability to send and receive signals is essential for the survival of the cell. Interactions between cells can be stable such as those made through cell junctions. These junctions are involved in the communication and organization of cells within a particular tissue. Others are transient or temporary such as those between cells of the immune system or the interactions involved in tissue inflammation. These types of intercellular interactions are distinguished from other types such as those between cells and the extracellular matrix. The loss of communication between cells can result in uncontrollable cell growth and cancer
