Which one of the following statements is correct a. men and women differ physically in some limited ways. b. overall, men are physically superior to women. c. overall, women are physically superior to men. d. there are no physical differences between men and women.

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.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
