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.
Plants produce oxygen and glucose as a result of photosynthesis
Answer:
Less biological relevant model and reduce cell to cell interaction.
Explanation:
The two main disadvantages of a 2D model of the digestive system is that it is less biological relevant model and reduce cell to cell interaction. The 2D model does not show high resemblance to reality and this model also fail to show the interactions of two cell surfaces with each other. In short, this model, does not give us complete knowledge about any biological system.
