1. A patient's height is 1.65 meters and their weight is 75kg. Calculate their BMI and interpret the result.

• A. 23.1 (Overweight)
• B. 25.3 (Overweight)
• C. 27.7 (Overweight)
• D. 32.8 (Obese)

Correct answer: C

Rationale: Divide weight (75kg) by height squared (1.65m^2) to get BMI (27.7). This falls within the "overweight" category (25-29.9 BMI).

2. Which hormone is crucial for stimulating sperm production in males?

• A. Estrogen
• B. Progesterone
• C. Testosterone
• D. Insulin

Correct answer: C

Rationale: The correct answer is C: Testosterone. Testosterone is the primary male sex hormone and is crucial for stimulating sperm production in males through the process of spermatogenesis. It is produced in the testes and plays a key role in the development and maintenance of male reproductive tissues, including the testes and prostate. Estrogen and progesterone are primarily female sex hormones, while insulin regulates blood sugar levels and metabolism. Therefore, testosterone is the hormone specifically responsible for stimulating sperm production in males.

3. The speaker's enthusiasm was contagious. Which word is the noun form of the adjective "enthusiastic"?

• A. enthusiastic
• B. enthusiastically
• C. enthusiasm
• D. enthuse

Correct answer: C

Rationale: Nouns can be formed from adjectives using various suffixes.

4. In which part of the cell are proteins modified, sorted, and packaged for transport?

• A. Ribosomes
• B. Golgi apparatus
• C. Endoplasmic reticulum (ER)
• D. Lysosomes

Correct answer: B

Rationale: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for transport. After proteins are synthesized in the rough endoplasmic reticulum (ER), they are transported to the Golgi apparatus where they undergo post-translational modifications and are sorted into vesicles for transport to their final destinations. Ribosomes are responsible for protein synthesis, the endoplasmic reticulum is involved in protein synthesis and folding, and lysosomes are responsible for digesting cellular waste. Therefore, the correct answer is B, Golgi apparatus, as it is specifically involved in the modification, sorting, and packaging of proteins for transport.

5. What is the process of cells responding to external stimuli, such as chemicals, temperature, or touch, called?

• A. Signal transduction
• B. Homeostasis
• C. Adaptation
• D. Metabolism

Correct answer: A

Rationale: Rationale: A) Signal transduction is the process by which cells respond to external stimuli, such as chemicals, temperature, or touch. When a cell receives a signal from its environment, it initiates a series of molecular events that ultimately lead to a specific cellular response. This process involves the transmission of signals from the cell surface to the interior of the cell, where they can trigger various cellular activities. B) Homeostasis refers to the ability of an organism to maintain internal stability and balance in response to external changes. While signal transduction plays a role in maintaining homeostasis by allowing cells to respond to external stimuli, it is not the specific process of cells responding to external stimuli. C) Adaptation is the process by which an organism adjusts to its environment over time through genetic changes or behavioral modifications. While cells can adapt to changes in their environment, the process of cells responding to external stimuli

6. A person throws a ball horizontally. What force changes the direction of the ball's motion?

• A. The force of throwing
• B. Gravitational force
• C. Air resistance
• D. Normal force from the ground

Correct answer: B

Rationale: When a person throws a ball horizontally, the initial force that propels the ball forward is the force of throwing (A). However, the force that changes the direction of the ball's motion is the gravitational force (B), which acts vertically downward and causes the ball to follow a curved path. Air resistance (C) and normal force from the ground (D) do not directly change the direction of the ball's motion in this scenario.
