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.
Enzymes.
They lower the activation energy (amount needed to start a reaction) and increases the reaction rate.

Iron, manganese, selenium, and calcium all provide day-to-day nutrients that body needs in order to function. Foods that are full of micronutrients can help strengthen cells, fight against harmful viruses, and boost the immune system.
Ken and Kendra share 50% of their genes. Lara an Lonnie share 100% of their genes.
The fraternal twins are just siblings that share the same womb. Each of them starts it's development as separate egg that is fertilized by a separate sperm, so they are no more similar than the other siblings.
The biological (identical) twins, on the other hand, come from the same fertilized egg, thus they share the same genes.
