Correct Answer: B

Rationale: Mesosomes are the internal extensions of the cell membrane, not the capsule, cell wall, or chromatin body. They play a crucial role in cell division and are essential for various cellular processes such as respiration and cell wall formation. Mesosomes are not associated with the capsule (choice A), cell wall (choice C), or chromatin body (choice D), making these options incorrect.

Correct Answer: B

Rationale: The correct answer is B: Luteinizing Hormone. The pituitary gland releases luteinizing hormone, which plays a crucial role in reproductive functions by stimulating ovulation in females and testosterone production in males. Choice A, Estrogen, is incorrect as estrogen is mainly produced by the ovaries. Choice C, Progesterone, is incorrect as progesterone is produced by the corpus luteum in the ovaries and the placenta during pregnancy. Choice D, Testosterone, is incorrect as testosterone is produced primarily in the testes in males and in smaller amounts in the ovaries and adrenal glands in females.

Correct Answer: B

Rationale: Starch is a polysaccharide, not a monosaccharide, making choice A incorrect. Glucose, choice B, is the correct answer as it is a monosaccharide, the simplest form of sugar. Cellulose, choice C, is a polysaccharide like starch, not a monosaccharide. Sucrose, choice D, is a disaccharide composed of glucose and fructose, not a monosaccharide. Glucose, being a monosaccharide, is a single sugar unit that serves as a primary energy source for living organisms.

Correct Answer: B

Rationale: A negative ion of sulfur would have 16 protons and 17 electrons since it gains one electron. The number of neutrons in an ion does not change, so the neutrons would remain at 16. Therefore, the correct answer is 16 neutrons and 17 electrons, which corresponds to choice B. Choice A is incorrect as it does not account for the extra electron gained by the negative ion. Choices C and D are incorrect because they propose a change in the number of neutrons, which is not affected by the ionization process.

Correct Answer: B

Rationale: The correct answer is B: Sudoriferous gland. Sudoriferous glands, also known as sweat glands, are responsible for producing sweat to regulate body temperature. Sebaceous glands produce sebum (oil) to lubricate the skin and hair. Hair follicles are associated with hair growth, not sweat production. Melanocytes are responsible for producing melanin for skin pigmentation, not sweat.
