1. Which force opposes the relative motion between surfaces in contact?

• A. Tension force
• B. Frictional force
• C. Gravitational force
• D. Magnetic force

Correct answer: b

Rationale: Friction is the force that opposes motion between surfaces in contact.

2. 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.

3. Which sentence uses the past perfect tense correctly?

• A. By the time I arrived, the party had already begun.
• B. I wish I had studied harder for the exam.
• C. We will have finished the project by Monday.
• D. She had been waiting for hours before he finally showed up.

Correct answer: A

Rationale: Option A expresses an action ("party began") completed before another past action ("I arrived").

4. Which vitamin is essential for calcium absorption and bone health?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin E

Correct answer: C

Rationale: The correct answer is Vitamin D. Vitamin D plays a crucial role in calcium absorption in the intestines, which is essential for maintaining strong and healthy bones. It helps regulate calcium and phosphorus levels in the body, promoting bone mineralization and growth. Vitamin A is important for vision and immune function, not specifically for bone health. Vitamin C is essential for collagen synthesis but not directly involved in calcium absorption. Vitamin E is an antioxidant that protects cells from damage but does not have a direct role in bone health. Therefore, Vitamin D is the correct choice for supporting calcium absorption and bone health.

5. A rectangular bandage measures 5cm by 8cm. What is the area covered by the bandage?

• A. 10cm
• B. 13cm
• C. 40cm^2
• D. 64cm^2

Correct answer: C

Rationale: 40cm^2: Multiply the length (5cm) by the width (8cm).

6. 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
