Explanation / Answer

21. The hormones are the messengers that are secreted by the endocrine glands. These messengers are responsible for controlling major body functions like the feeling of hunger, reproduction, and even the mood swings. these hormones travel throughout the body in the blood and reach the target organ. These secretions by the gland control the basic processes as well as the complex process of the body by traveling throughout the body. So, the correct option is B.

22. The exocrine gland is described as the glands that secrete their secretions by a duct whereas the endocrine gland secretes the chemical messenger directly into the tissue or the bloodstream. the secretions of the endocrine glands are known as hormones. The pancreas is the gland that functions both as an endocrine gland and exocrine gland. The pancreas is a glandular organ that is present in the upper abdomen serving as two glands. The pancreas secretes enzymes for breaking down of proteins, lipids, nucleic acids, and carbohydrates when it functions as an exocrine gland while it secretes glucagon and insulin hormones when it functions as an endocrine gland. So, the correct option is D while the rest of the given options are endocrine glands.

23.The hormone when secreted by the gland reaches the specific target organ for which they are secreted. When the hormone reaches the target organ then only it responds, this happens because only the target organ has the specific receptor for the action of the specified hormone. The hormone will not be able to perform the required action if it does not reach the target organ and its specific receptors. So, the correct option is B.

24. The correct option is C. The synergistic effect is responsible for the production of the 300,000 sperms per minute. This is because the individual effect of both the follicle stimulating hormone and the testosterone is less than their combined effect. The combined effect of both the hormone results in the significant production of sperms
