Correct Answer: D

Rationale: The correct answer is D: Hypertension. Hypertension, or high blood pressure, can lead to blood clots and stroke by causing damage to blood vessels and increasing the risk of clot formation. Elevated blood pressure can strain the blood vessel walls, making them more prone to damage and clot formation. This can lead to blockages in blood flow to the brain, causing a stroke. Aneurysm (A) is a weakened area in a blood vessel that can rupture but not necessarily cause blood clots. Arrhythmia (B) is an irregular heartbeat that can increase the risk of stroke but is not directly related to blood clot formation. Asthma (C) is a respiratory condition that does not directly cause blood clots or stroke.

Correct Answer: B

Rationale: The correct answer is B: Nucleotide. Nucleotides are the building blocks of DNA, consisting of a sugar molecule, a phosphate group, and a nitrogenous base. They are linked together in a specific sequence to form the DNA molecule's double helix structure. Amino acids (choice A) are the building blocks of proteins, not DNA. Phosphate groups (choice C) are components of nucleotides but are not the sole building blocks of DNA. Fatty acids (choice D) are not involved in the structure of DNA at all. Therefore, the correct answer is nucleotide as it accurately represents the basic components that make up DNA.

Correct Answer: D

Rationale: The correct answer is D because muscle tissue is indeed involved in all the functions listed. Muscles generate body heat through metabolism, stabilize joints by providing support and movement, and help maintain posture by keeping the body in an upright position. Therefore, muscle tissue plays a crucial role in all these functions. Choices A, B, and C are incorrect individually as they only represent a part of the functions that muscle tissue is involved in, whereas the correct answer encompasses all aspects of muscle function in the body.

Correct Answer: C

Rationale: The correct answer is C: Emulsify fats. Bile helps emulsify fats by breaking them down into smaller droplets, increasing the surface area for enzymes to digest fats. This aids in the absorption of fats and fat-soluble vitamins in the small intestine. Choice A is incorrect because bile does not break down carbohydrates. Choice B is incorrect as bile does not break down proteins. Choice D is incorrect because bile does not neutralize stomach acid; rather, it helps with fat digestion in the small intestine.

Correct Answer: C

Rationale: The correct answer is C: Peripheral nervous system. This system consists of nerves that connect the sensory organs (such as eyes, ears, skin) to the central nervous system (brain and spinal cord). It transmits sensory information from these organs to the CNS for processing. The autonomic nervous system (A) controls involuntary functions, somatic nervous system (B) controls voluntary movements, and central nervous system (D) processes and integrates information but does not directly transmit signals from sensory organs.
