1. What do nociceptors detect?

Correct answer: C

Rationale: Nociceptors are specialized sensory receptors that detect and transmit signals related to pain. These receptors are activated by noxious stimuli that can potentially cause tissue damage or injury, triggering the perception of pain in the brain. Therefore, the correct answer is 'Pain.' Choices A, B, and D are incorrect because nociceptors specifically respond to painful stimuli, not deep pressure, vibration, or temperature.

2. DNA has both a 'sense' and 'antisense' strand. What is true about the antisense strand?

Correct answer: B

Rationale: The correct answer is B. The antisense strand runs 3' to 5', which is opposite to the direction of the sense strand. It serves as the template strand for transcription, where an RNA molecule is synthesized complementary to the antisense strand. Choice A is incorrect because the antisense strand runs in the opposite direction. Choice C is incorrect as the antisense strand is primarily involved in transcription, not replication. Choice D is incorrect as the direction of DNA storage is not determined by the antisense strand.

3. What is the primary function of the large intestine?

Correct answer: D

Rationale: The primary function of the large intestine is to absorb water and electrolytes from the indigestible food matter that passes through it. This absorption process aids in the formation of solid waste (feces) before it is excreted from the body. Choices A, B, and C are incorrect because the large intestine does not primarily digest and absorb nutrients, store and mix food, or break down carbohydrates. These functions are primarily carried out by the small intestine.

4. Abduction is defined as which of the following?

Correct answer: A

Rationale: Abduction is defined as movement away from the midline of the body. This movement occurs in the coronal plane and is essential in various body functions such as raising the arms sideways. Choices B, C, and D describe movements that are different from abduction. Choice B refers to flexion, which decreases the angle of a joint. Choice C describes extension, which increases the angle of a joint. Choice D defines adduction, which involves movement towards the midline of the body. Therefore, the correct answer is choice A.

5. Which of the following systems is responsible for transporting blood throughout the body?

Correct answer: B

Rationale: The correct answer is B: Circulatory. The circulatory system, made up of the heart, blood vessels, and blood, is responsible for transporting blood throughout the body. It plays a vital role in delivering oxygen, nutrients, hormones, and removing waste products from cells. The respiratory system, on the other hand, is responsible for gas exchange in the lungs. The nervous system transmits signals between different parts of the body, while the digestive system processes food and absorbs nutrients from it. Therefore, choices A, C, and D are incorrect as they are not primarily involved in the transportation of blood throughout the body.
