1. What is the relationship between mass and inertia?

• A. Mass is a measure of inertia
• B. Mass has no relation to inertia
• C. Inertia is a measure of weight
• D. Inertia increases with decreasing mass

Correct answer: a

Rationale: Mass is a measure of the amount of matter in an object and is directly related to its inertia.

2. Which of the following situations represents work being done on an object?

• A. Pushing against a wall without moving it
• B. Carrying a heavy object without lifting it
• C. Lifting a box to place it on a shelf
• D. Holding a book stationary in your hand

Correct answer: c

Rationale: Work is done when a force is applied to move an object over a distance.

3. What is the unit of measurement for force in the International System of Units (SI)?

• A. Newton (N)
• B. Kilogram (kg)
• C. Joule (J)
• D. Meter per second squared (m/s²)

Correct answer: a

Rationale: Force is measured in Newtons (N) in the SI system.

4. Which type of cell has a nucleus but lacks membrane-bound organelles?

• A. Plant cell
• B. Prokaryotic cell
• C. Animal cell
• D. Fungal cell

Correct answer: B

Rationale: The correct answer is B: Prokaryotic cell. Prokaryotic cells are characterized by having a nucleus, known as the nucleoid, which contains genetic material but lacks a membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. Plant and animal cells (options A and C) are eukaryotic cells that have a nucleus and membrane-bound organelles. Fungal cells (option D) are also eukaryotic cells with a nucleus and organelles. Understanding the difference between prokaryotic and eukaryotic cells is essential in biology to grasp the diversity of cell structure and function.

5. Katherine tells one of the staff, “I don’t have time to discuss the matter with you now. See me

• A. Smoothing
• B. Compromise
• C. Avoidance
• D. Restriction

Correct answer: B

Rationale: The correct answer is B: 'Compromise.' In this scenario, Katherine is willing to engage with the staff member but suggests they postpone the discussion to a later time. This demonstrates a willingness to find a middle ground or reach a mutual agreement, which aligns with the concept of compromise. 'Smoothing' involves downplaying differences to maintain harmony, 'Avoidance' is ignoring or postponing the issue altogether, and 'Restriction' refers to limiting the interaction or communication. Therefore, 'Compromise' best fits the situation where Katherine is open to discussing the matter at a more suitable time.

6. Which part of the brain is responsible for coordinating various sensory inputs, regulating sleep, and maintaining wakefulness?

• A. Cerebrum
• B. Hypothalamus
• C. Medulla oblongata
• D. Reticular formation

Correct answer: d

Rationale: The correct answer is D: Reticular formation. The reticular formation is a network of neurons located in the brainstem that plays a crucial role in regulating consciousness, arousal, and sleep-wake transitions. It receives sensory inputs from various parts of the body and helps coordinate these inputs to maintain wakefulness and alertness. While the cerebrum is responsible for higher cognitive functions and the hypothalamus regulates various physiological processes like body temperature and hunger, the reticular formation specifically focuses on integrating sensory information and controlling wakefulness.
