1. Which word in the following sentence is a conjunction: 'The little girl wanted a cookie, but she didn’t take one.'

• A. little
• B. but
• C. take
• D. the

Correct answer: B

Rationale: 'But' is the conjunction in this sentence. A conjunction is a word that connects clauses or sentences. In this case, 'but' links two contrasting ideas: the little girl wanting a cookie and her decision not to take one. The other options are not conjunctions; 'little' is an adjective, 'take' is a verb, and 'the' is a definite article.

2. What event occurs during telophase?

• A. The nuclear envelope disappears.
• B. Organelles double in number.
• C. Chromosomes separate.
• D. Two nuclei are formed.

Correct answer: D

Rationale: During telophase, the final stage of mitosis, the separated chromosomes reach opposite poles of the cell. At this stage, a new nuclear envelope forms around each set of chromosomes, creating two distinct nuclei. This marks the completion of cell division. Choices A, B, and C are incorrect because the disappearance of the nuclear envelope typically occurs during prophase, organelles do not double in number during telophase, and chromosomes separate during anaphase, not telophase.

3. Which structure is responsible for carrying oxygen to the cells?

• A. Hemoglobin
• B. Plasma
• C. Platelets
• D. Red blood cells

Correct answer: A

Rationale: Hemoglobin, located in red blood cells, is responsible for binding to oxygen in the lungs and transporting it to tissues throughout the body. Red blood cells contain hemoglobin, making them the primary carrier of oxygen to cells. Hemoglobin is the correct answer because it is the protein within red blood cells that directly binds to oxygen for transport. Plasma is the liquid component of blood and does not carry oxygen. Platelets are responsible for blood clotting and have no role in oxygen transport. While red blood cells do carry oxygen, it is specifically the hemoglobin within them that performs this function.

4. Choose the meaning of the word 'intramuscularly' in the following sentence: 'This vaccine must only be used intramuscularly and as a single-dose vial.'

• A. Between muscles
• B. Into muscles
• C. Without muscles
• D. On top of muscles

Correct answer: B

Rationale: The word 'intramuscularly' in the sentence indicates that the vaccine should be used by injection directly into the muscles. This means the correct meaning is 'into muscles,' making option B the most suitable choice. Choices A, C, and D are incorrect because 'intramuscularly' specifically refers to administering something inside the muscle, not between muscles, without muscles, or on top of muscles.

5. What is another word for Asymmetric?

• A. Even
• B. Uneven
• C. Identical
• D. Matching

Correct answer: B

Rationale: The correct answer is B: 'Uneven.' Asymmetric means lacking symmetry or being uneven, so the term 'Uneven' is the most appropriate synonym. 'Even' (choice A) means equal or level, which is the opposite of asymmetric. 'Identical' (choice C) means similar or the same, and 'Matching' (choice D) means corresponding or fitting together, neither of which captures the meaning of asymmetric.
