1. Which mineral supports the function of the thyroid?

• A. Manganese
• B. Iodine
• C. Phosphorus
• D. Zinc

Correct answer: B

Rationale: Iodine is the mineral that supports the function of the thyroid. The thyroid gland requires iodine to produce thyroid hormones, which are essential for regulating metabolism and other important bodily functions. A deficiency in iodine can lead to thyroid disorders such as hypothyroidism or goiter. Manganese (Choice A), Phosphorus (Choice C), and Zinc (Choice D) do not play a direct role in supporting the thyroid function like iodine does. While these minerals are important for various bodily functions, they are not specifically required for the thyroid gland's hormone production.

2. What is the main function of the nervous system?

• A. Transporting blood
• B. Protecting the body from infection
• C. Regulating body temperature
• D. Digesting food

Correct answer: C

Rationale: The main function of the nervous system is to control and coordinate body activities by transmitting signals between different parts of the body and responding to internal and external stimuli. This allows for the regulation of body temperature, movement, sensory perception, and various other functions necessary for homeostasis. Choices A, B, and D are incorrect as they do not align with the primary role of the nervous system. Transporting blood is mainly carried out by the circulatory system, protecting the body from infection is a function of the immune system, and digesting food is the role of the digestive system.

3. Which lobe of the brain is primarily responsible for auditory functioning?

• A. Frontal lobe
• B. Temporal lobe
• C. Occipital lobe
• D. Parietal lobe

Correct answer: B

Rationale: The correct answer is B: Temporal lobe. The temporal lobe of the brain is primarily responsible for processing auditory information, including sound perception, speech recognition, and language comprehension. Damage to the temporal lobe can lead to difficulties in hearing, understanding spoken language, and recognizing familiar sounds. Choices A, C, and D are incorrect because the frontal lobe is mainly associated with functions such as decision-making and personality, the occipital lobe is primarily responsible for processing visual information, and the parietal lobe is involved in sensory functions and spatial processing, not auditory functioning.

4. Which type of blood cell is responsible for carrying oxygen?

• A. Red blood cells
• B. White blood cells
• C. Platelets
• D. Plasma cells

Correct answer: A

Rationale: The correct answer is A: Red blood cells. Red blood cells, also known as erythrocytes, are specialized cells designed to transport oxygen from the lungs to tissues and organs throughout the body. These cells contain hemoglobin, a protein that binds to oxygen molecules in the lungs and releases them in other parts of the body where oxygen is needed for cellular respiration. White blood cells (choice B) are part of the immune system, responsible for fighting infections. Platelets (choice C) are involved in blood clotting. Plasma cells (choice D) are a type of white blood cell that produces antibodies to help the body fight off infections.

5. Which type of joint is found in the knee?

• A. Ball and socket joint
• B. Hinge joint
• C. Pivot joint
• D. Saddle joint

Correct answer: B

Rationale: The correct answer is a hinge joint. The knee is a hinge joint that allows for flexion and extension movements, enabling the leg to bend and straighten. This type of joint is designed for movement along one plane, similar to a door hinge. Choice A, ball and socket joint, is incorrect as this type of joint allows for a wider range of motion in multiple directions, unlike the knee joint. Choice C, pivot joint, and Choice D, saddle joint, are also incorrect as they do not accurately describe the type of joint found in the knee.
