Question 1 of 5

Which of the following structures in the skin is responsible for producing sweat?

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. They are distributed throughout the skin and play a vital role in maintaining homeostasis. Sebaceous glands (A) produce sebum, hair follicles (C) are responsible for hair growth, and melanocytes (D) produce melanin for skin pigmentation. Therefore, B is the correct choice as it directly relates to sweat production in the skin.

Question 2 of 5

Mesosomes are the internal extensions of which of the following?

Correct Answer: B

Rationale: The correct answer is B: Cell membranes. Mesosomes are internal extensions of the cell membrane in prokaryotic cells. They are involved in cell division, DNA replication, and formation of respiratory enzymes. Choice A (Capsule) is incorrect because capsules are external structures surrounding the cell membrane. Choice C (Cell wall) is incorrect as mesosomes are not related to the cell wall, which provides structural support. Choice D (Chromatin body) is incorrect because chromatin bodies are found in eukaryotic cells, not prokaryotic cells where mesosomes are present.

Question 3 of 5

Which of the following has a smaller genetic scale than a chromosome?

Correct Answer: B

Rationale: The correct answer is B: Gene. A gene is a smaller unit of genetic information than a chromosome. Chromosomes contain many genes, so they are larger in scale. The genome (option A) refers to the complete set of an organism's genetic material, which includes all the chromosomes. DNA (option C) is the genetic material that makes up chromosomes and genes. Option D is incorrect because while all the listed choices are related to genetics, genes are specifically smaller than chromosomes.

Question 4 of 5

Which of the following structures helps filter pathogens from the blood?

Correct Answer: C

Rationale: The correct answer is C: Spleen. The spleen filters pathogens from the blood through its white pulp, which contains immune cells that detect and destroy harmful microorganisms. The spleen also removes old or damaged red blood cells. A: Lymph nodes filter lymph, not blood. B: Kidneys filter waste from the blood but not pathogens. D: Pancreas is primarily involved in digestion and hormone regulation, not blood filtration.

Question 5 of 5

Which of the following organs is responsible for producing bile?

Correct Answer: B

Rationale: The correct answer is B: Liver. The liver is responsible for producing bile, which helps in the digestion and absorption of fats. It is stored in the gallbladder (not produced by it), which releases it into the small intestine when needed. The pancreas produces digestive enzymes and insulin, not bile. The stomach produces gastric juices, not bile. In summary, the liver is the primary organ responsible for bile production, making it the correct choice.
