1. A symbiotic relationship where one organism benefits and the other is not harmed is called:

• A. Mutualism
• B. Commensalism
• C. Parasitism
• D. Predation

Correct answer: B

Rationale: Rationale: A) Mutualism: In mutualism, both organisms involved benefit from the relationship. B) Commensalism: In commensalism, one organism benefits while the other is neither helped nor harmed. This is the relationship described in the question. C) Parasitism: In parasitism, one organism benefits at the expense of the other organism, which is harmed. D) Predation: In predation, one organism (predator) kills and consumes another organism (prey) for food.

2. Identify the independent clause in the following sentence: "While the chef prepared dinner, the guests chatted and enjoyed the music."

• A. While the chef prepared dinner
• B. the guests chatted and enjoyed the music
• C. While the chef prepared dinner,
• D. the guests chatted and enjoyed

Correct answer: B

Rationale: An independent clause expresses a complete thought and can stand alone as a sentence.

3. A salt solution that conducts electricity well is most likely

• A. A saturated solution
• B. A concentrated solution of a strong electrolyte
• C. A dilute solution of a weak acid
• D. A mixture of a neutral compound and water

Correct answer: B

Rationale: The correct answer is B: "A concentrated solution of a strong electrolyte." Strong electrolytes completely dissociate into ions in solution, thereby increasing the conductivity of the solution. Concentrated solutions have a higher amount of dissolved solute particles, which leads to more ions available for conducting electricity. In contrast, saturated solutions may contain undissolved solute, limiting the number of ions in solution. Dilute solutions have fewer ions and weak acids only partially dissociate, reducing conductivity. A neutral compound and water do not provide ions for conducting electricity. Therefore, a concentrated solution of a strong electrolyte is most likely to conduct electricity well due to the high concentration of ions present.

4. Which sentence uses the phrase "by the way" correctly?

• A. By the way, I forgot to tell you I won the lottery!
• B. He finished his report, by the way, it was very well-written.
• C. I have some news for you, by the way.
• D. By the way, the movie starts at 8 pm.

Correct answer: C

Rationale: Option C introduces additional information that is not directly related to the previous sentence, making it a natural use of "by the way."

5. Identify the interjection in the following sentence: Ouch! I stubbed my toe on the table leg.

• A. table
• B. leg
• C. ouch
• D. stubbed

Correct answer: C

Rationale: Interjections express emotions or sudden feelings. "Ouch" conveys a feeling of pain.

6. Which type of muscle is characterized by voluntary control and is responsible for body movement?

• A. Cardiac muscle
• B. Smooth muscle
• C. Skeletal muscle
• D. Connective tissue

Correct answer: c

Rationale: The correct answer is C: Skeletal muscle. Skeletal muscles are characterized by voluntary control, meaning they are under conscious control, allowing us to move our body parts as desired. These muscles are attached to bones and are responsible for movements such as walking, running, and lifting objects. Cardiac muscle (A) is found in the heart and is involuntary, while smooth muscle (B) is found in internal organs and is also involuntary. Connective tissue (D) provides support and structure to the body but is not responsible for body movements.
