1. 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.

2. Homologous structures are those that:

A. Have the same function but different origins
B. Have different functions but the same origin
C. Are similar in appearance and function due to shared ancestry
D. Are identical in both appearance and function

Correct answer: C

Rationale: Rationale: - Option A is incorrect because structures with the same function but different origins are analogous structures, not homologous structures. - Option B is incorrect because structures with different functions but the same origin are also not homologous structures; they are considered to be vestigial structures. - Option D is incorrect because structures that are identical in both appearance and function are not necessarily homologous; they could be the result of convergent evolution. Homologous structures are those that share similarities in appearance and function due to being inherited from a common ancestor. These structures may have undergone modifications over time to adapt to different functions in different species, but their fundamental similarities can be traced back to a shared evolutionary history.

3. The element responsible for the yellow color of bananas is:

A. Potassium
B. Calcium
C. Phosphorus
D. Carotene

Correct answer: D

Rationale: Carotene is a type of carotenoid pigment found in fruits and vegetables, contributing to their yellow, orange, and red hues.

4. What is the best way to revise the sentence: "Her eyes glistened with tears in the moonlight"?

A. Her eyes glistened in the moonlight, with tears.
B. Tears glistened in her eyes with moonlight.
C. Her eyes, in the moonlight, glistened with tears.
D. Tears made her eyes glisten in the moonlight.

Correct answer: C

Rationale: Option C rearranges the elements for smoother flow and emphasis on the tears.

5. Define the term "velocity" in relation to motion.

A. Speed in a specific direction
B. Distance traveled in a given time
C. Rate of change of position
D. Acceleration due to gravity

Correct answer:

Rationale: Velocity is the rate of change of position concerning direction, unlike speed which only refers to distance traveled per unit time.

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.
