1. If you are an assiduous worker, you are probably ______.

• A. Lazy
• B. Industrious
• C. Inconsistent
• D. Procrastinating

Correct answer: B

Rationale: The correct answer is B, 'Industrious.' Assiduous means showing great care and perseverance in your work, which aligns with being industrious. Choice A, 'Lazy,' is incorrect as it is the opposite of assiduous. Choice C, 'Inconsistent,' does not directly relate to being assiduous, and choice D, 'Procrastinating,' suggests delaying tasks which is contrary to being assiduous.

2. Which organ is responsible for the production of insulin?

• A. Thyroid gland
• B. Pituitary gland
• C. Pancreas
• D. Adrenal gland

Correct answer: C

Rationale: The correct answer is C: Pancreas. The pancreas is responsible for producing insulin, a hormone that regulates blood glucose levels by facilitating the uptake of glucose into cells. Insulin is crucial for maintaining proper blood sugar levels and is produced by specialized cells within the pancreas known as beta cells. Choices A, B, and D are incorrect because the thyroid gland, pituitary gland, and adrenal gland do not produce insulin. The thyroid gland produces hormones that regulate metabolism, the pituitary gland releases various hormones that control other glands, and the adrenal gland produces hormones like cortisol and adrenaline.

3. Tonicity refers to the movement of:

• A. Water
• B. Solute
• C. Cells
• D. None of the above

Correct answer: A

Rationale: Tonicity refers to the movement of water across a membrane in response to differences in solute concentration. In a hypertonic solution, where there is a higher concentration of solutes outside the cell, water will move out of the cell to try to reach equilibrium. In a hypotonic solution, where there is a lower concentration of solutes outside the cell, water will move into the cell to balance the concentrations. Cells and solutes themselves do not actively move in response to tonicity; it is the movement of water that helps achieve equilibrium. Therefore, the correct answer is water (Choice A). Choices B, C, and D are incorrect as tonicity specifically refers to water movement and not the movement of solutes, cells, or none of the above.

4. Which bone is shorter in the forearm?

• A. Humerus
• B. Radius
• C. Scapula
• D. Fibula

Correct answer: B

Rationale: The correct answer is B: Radius. The forearm consists of two long bones: the radius and the ulna. The radius is located on the thumb side of the forearm and is shorter than the ulna, which is on the pinky side. The humerus is the bone located in the upper arm, the scapula is the shoulder blade bone, and the fibula is a bone in the lower leg. Therefore, they are not the shorter bone in the forearm.

5. A 25-cm spring stretches to 28 cm when a force of 12 N is applied. What would its length be if that force were doubled?

• A. 31 cm
• B. 40 cm
• C. 50 cm
• D. 56 cm

Correct answer: A

Rationale: When the 12 N force stretches the spring from 25 cm to 28 cm, it causes a length increase of 28 cm - 25 cm = 3 cm. Therefore, each newton of applied force causes an extension of 3 cm / 12 N = 0.25 cm/N. If the force is doubled to 24 N, the spring would extend by 24 N × 0.25 cm/N = 6 cm more than its original length of 25 cm. Thus, the new length of the spring would be 25 cm + 6 cm = 31 cm. Choice A, 31 cm, is the correct answer as calculated. Choices B, C, and D are incorrect as they do not consider the relationship between force and extension in the spring, leading to incorrect calculations of the new length.
