1. She decides to have a decentralized staffing system. Which of the following is an advantage

• A. greater control of activities
• B. Conserves time
• C. Compatible with computerization
• D. Promotes better interpersonal relationship

Correct answer: A

Rationale: The correct answer is A: 'greater control of activities.' Having a decentralized staffing system allows for the delegation of decision-making to lower levels of the organization, which can result in greater control over activities. This can lead to quicker responses to issues and better alignment with specific departmental needs. Options B, C, and D do not directly relate to the advantage of a decentralized staffing system. While conserving time, compatibility with computerization, and promoting better interpersonal relationships are important considerations in staffing decisions, they do not specifically align with the advantage of greater control that a decentralized system provides.

2. What property of a wave determines its speed in a given medium?

• A. Amplitude
• B. Wavelength
• C. Frequency
• D. Medium's properties

Correct answer: d

Rationale: The speed of a wave is determined by the properties of the medium it travels through.

3. Which of the following is NOT a property of a catalyst?

• A. Increases the rate of a reaction
• B. Remains unchanged after the reaction
• C. Lowers the activation energy
• D. Creates new products

Correct answer: D

Rationale: A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It remains unchanged after the reaction, which eliminates option B. A catalyst works by lowering the activation energy required for the reaction to occur, which eliminates option C. A catalyst does not create new products in a reaction; it only facilitates the conversion of reactants into products more efficiently. Therefore, option D is NOT a property of a catalyst.

4. Identify the type of error in the sentence "They went to the store, and bought groceries, then went home."

• A. Run-on sentence
• B. Comma splice
• C. Dangling modifier
• D. Subject-verb agreement

Correct answer: A

Rationale: The sentence combines two independent clauses without proper punctuation, forming a run-on sentence.

5. Insulin, a hormone responsible for regulating blood sugar levels, is produced by the:

• A. Parathyroid gland
• B. Pancreas
• C. Thymus gland
• D. Ovaries

Correct answer: B

Rationale: The correct answer is B: Pancreas. Insulin is a hormone that plays a crucial role in regulating blood sugar levels by allowing cells to take in glucose from the bloodstream. The pancreas is an organ located near the stomach that contains clusters of cells called islets of Langerhans, which are responsible for producing insulin. The parathyroid gland, option A, regulates calcium levels in the blood. The thymus gland, option C, is involved in the development of the immune system. The ovaries, option D, produce hormones like estrogen and progesterone but not insulin. Therefore, the pancreas is the correct gland responsible for producing insulin.

6. The process by which an organism adapts to its environment through inherited traits is known as

• A. Acclimatization
• B. Behavioral ecology
• C. Natural selection
• D. Niche partitioning

Correct answer: C

Rationale: Rationale: A) Acclimatization refers to the short-term physiological adjustments an individual organism makes in response to changes in its environment. This process is reversible and does not involve inherited traits. B) Behavioral ecology is the study of how behavior contributes to an organism's survival and reproduction in its environment. While behavior can be influenced by natural selection, it is not the process by which an organism adapts through inherited traits. C) Natural selection is the process by which organisms with advantageous traits for their environment are more likely to survive, reproduce, and pass on those traits to their offspring. Over time, this leads to the adaptation of populations to their environments. D) Niche partitioning is the process by which species divide resources to reduce competition within an ecosystem. While this can influence the evolution of species, it is not the process by which an organism adapts through inherited traits.
