1. What is the name for the tiny particles that make up atoms?

• A. Protons
• B. Electrons
• C. Neutrons
• D. Subatomic particles

Correct answer: D

Rationale: Protons, neutrons, and electrons are all subatomic particles that make up atoms.

2. What is the meaning of the idiom "to bite off more than one can chew"?

• A. To be overly confident
• B. To take on more than one can handle
• C. To be easily discouraged
• D. To be meticulous in planning

Correct answer: B

Rationale: The idiom warns against undertaking a task exceeding one's capabilities.

3. In a horizontal chart, the lowest level worker is located at the

• A. Leftmost box
• B. Middle
• C. Rightmost box
• D. Bottom

Correct answer: B

Rationale: In a horizontal chart, the lowest level worker is typically positioned at the leftmost side, with higher-level workers placed to the right. This arrangement signifies hierarchy, with the top level usually being on the rightmost side. Therefore, the correct answer is B: 'Middle,' as the lowest level worker is situated towards the left of the chart, not the extreme left or right. This positioning helps visually represent the organization's structure and indicates the progression from lower to higher levels as one moves from left to right on the chart.

4. 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

5. Which of the following is NOT a typical component of healthy semen?

• A. Sperm
• B. Fructose (sugar)
• C. Prostaglandins
• D. Urine

Correct answer: D

Rationale: The correct answer is D: Urine. Semen is a mixture of fluids from various glands in the male reproductive system. It typically contains sperm, fructose (sugar) to provide energy for the sperm, and prostaglandins to aid in sperm motility. Urine is not a normal component of healthy semen. It is important to note that urine and semen travel through different pathways in the male body, and they should not mix. Therefore, the presence of urine in semen would indicate a potential issue or infection in the urinary system. Understanding the components of healthy semen is crucial for assessing male reproductive health and fertility.

6. Which statement accurately describes cytokinesis in animal cells?

• A. Which statement accurately describes cytokinesis in animal cells?
• B. A cell plate forms in the center of the dividing cell, eventually separating the cytoplasm into two daughter cells.
• C. A cell plate forms in the center of the dividing cell, eventually separating the cytoplasm into two daughter cells.
• D. The nucleus elongates and pulls apart, physically dividing the cytoplasm into two.

Correct answer: B

Rationale: Rationale: A) This statement is a duplicate of option C and does not accurately describe cytokinesis in animal cells. B) In animal cells, during cytokinesis, a cleavage furrow forms in the center of the dividing cell. This furrow deepens and eventually pinches the cytoplasm into two daughter cells. This process is distinct from plant cells, where a cell plate forms. C) This statement is a duplicate of option A and does not accurately describe cytokinesis in animal cells. D) This statement describes the process of nuclear division (mitosis) rather than cytokinesis, which is the division of the cytoplasm.
