Answer:
a. Men and women differ physically in some limited ways.
Explanation:
The concept of physical superiority is a relative one, so to say that one gender is physically superior to another is wrong not only socially, but also biologically. That being said, there are still some physical differences between men and women. For instance, men in average, tend to be taller and stronger than women, while women tend to have a higher pain threshold than men. Therefore, the most appropriate statement is that a. Men and women differ physically in some limited ways.

Answer:
Darwin proposed the theory of natural selection to explain the process of evolution. According to Darwin’s theory of natural selection, all organisms have the potential to reproduce limitlessly irrespective of the fact that each species maintain a constant density over time. However, the struggle for existence, i.e. the competition among individuals for available resources to survive and reproduce, put a check on species density (D) and maintains it at a constant level (B). Survival of fittest is unequal ability of individuals to survive and reproduce based on suitability of their inherited characters to prevailing environmental conditions (A). It imparts the reproductive advantage to certain organisms which account for major part of the gene pool of the species. Thus, natural selection favors the individual with survival and/or reproductive advantage over others under existing environmental condition (E). Thus, the correct answer is option C.
Answer:
DNA replication is the process by which DNA makes a copy of itself during cell division. The separation of the two single strands of DNA creates a 'Y' shape called a replication 'fork'. The two separated strands will act as templates for making the new strands of DNA.
