1. What does 'Obsolete' mean?

• A. Innovative
• B. Outdated
• C. Effective
• D. Advanced

Correct answer: B

Rationale: The correct answer is 'B: Outdated.' Obsolete refers to something that is outdated or no longer in use. 'Innovative' (choice A) means introducing new ideas or methods; 'Effective' (choice C) means successful in producing a desired result; 'Advanced' (choice D) means far on or ahead in development or progress. Therefore, 'Outdated' is the most appropriate antonym for 'Obsolete.'

2. Which of the following organelles is responsible for producing ATP in cells?

• A. Nucleus
• B. Mitochondrion
• C. Chloroplast
• D. Lysosome

Correct answer: B

Rationale: The correct answer is 'Mitochondrion.' Mitochondria are known as the powerhouse of the cell and are responsible for producing ATP, the energy currency of the cell. The nucleus is responsible for storing genetic material and controlling cell activities, not for ATP production. Chloroplasts are found in plant cells and are responsible for photosynthesis, not ATP production. Lysosomes are involved in digestion and waste removal, not ATP production.

3. How many pairs of chromosomes do all humans have?

• A. 24 pairs
• B. 23 pairs
• C. 22 pairs
• D. 20 pairs

Correct answer: B

Rationale: All humans have 23 pairs of chromosomes, totaling 46 chromosomes. Choice A is incorrect because humans do not have 24 pairs. Choice C is incorrect as humans have 23 pairs, not 22 pairs. Choice D is incorrect as humans have 23 pairs of chromosomes, not 20 pairs.

4. Prokaryotic cells:

• A. Have a nucleus
• B. Have a capsule
• C. Have membrane-bound organelles
• D. Cannot move on their own

Correct answer: B

Rationale: Prokaryotic cells do not have a nucleus or membrane-bound organelles. One characteristic feature of prokaryotic cells is the presence of a capsule, which is a protective layer outside the cell wall. This capsule helps the prokaryotic cell adhere to surfaces, evade the host immune system, and protect against desiccation. Choice A is incorrect because prokaryotic cells lack a nucleus. Choice C is incorrect as prokaryotic cells do not have membrane-bound organelles. Choice D is incorrect as prokaryotic cells can move using structures like flagella or pili.

5. Select the meaning of the underlined word in the following sentence. What is the prognosis for those accident victims?

• A. Expected outcome
• B. Treatment option
• C. Fabrication
• D. Fabrication

Correct answer: A

Rationale: In this sentence, the word 'prognosis' refers to the expected outcome or forecast for the accident victims. It indicates what is likely to happen in terms of their recovery or overall condition following the accident. Therefore, the correct meaning of the underlined word is the expected outcome, which is option A. Choices B, C, and D are incorrect because 'prognosis' does not refer to a treatment option or fabrication.
