1. What is the meaning of Regulations?

• A. Rules for Conduct
• B. Official Standards
• C. Personal Guidelines
• D. Suggestions

Correct answer: A

Rationale: Regulations refer to rules or directives established by authorities to govern conduct or actions. Therefore, the correct answer is A - 'Rules for Conduct.' Choice B, 'Official Standards,' is incorrect as regulations go beyond just setting standards to include specific rules for behavior. Choice C, 'Personal Guidelines,' is incorrect as regulations are not individualized but are generally applicable rules. Choice D, 'Suggestions,' is incorrect as regulations are mandatory and carry legal weight, unlike suggestions which are optional and not binding.

2. What does Redundancy mean?

• A. Deficiency
• B. Surplus
• C. Delicate
• D. Abundance

Correct answer: B

Rationale: Redundancy means having more than is needed, making 'Surplus' the correct choice. The term does not relate to 'Deficiency' (lack), 'Delicate' (fragile), or 'Abundance' (plenty). In the context of this question, Redundancy refers to an excess or surplus of something.

3. Select the word or phrase that makes this sentence grammatically correct: '____ screaming took the shopkeeper by surprise.'

• A. We
• B. They
• C. Them
• D. Our

Correct answer: D

Rationale: In this sentence, 'Our' is the possessive pronoun that correctly indicates possession, making the sentence grammatically correct. The sentence implies that the screaming belonged to a group that includes the shopkeeper. Therefore, 'Our' is the appropriate choice. The other options ('We,' 'They,' 'Them') are incorrect as they do not convey possession as required in the sentence.

4. How does asexual reproduction differ from sexual reproduction?

• A. asexual reproduction results in all cells being identical to the original cell; sexual reproduction results in half of the cells being identical to the original cell
• B. asexual reproduction results in two cells that contribute genetic material to daughter cells, resulting in significantly greater variation
• C. sexual reproduction involves two cells that contribute genetic material to daughter cells, resulting in significantly greater variation
• D. sexual reproduction involves one cell that yields all cells produced to be identical

Correct answer: C

Rationale: Sexual reproduction involves two cells (gametes) that contribute genetic material to daughter cells, resulting in significantly greater genetic variation in the offspring. This genetic variation is essential for evolution and adaptation to environmental changes. In contrast, asexual reproduction involves one cell dividing to produce offspring that are genetically identical to the parent cell. Choice A is incorrect because sexual reproduction does not result in half of the cells being identical to the original cell; it involves two cells contributing genetic material. Choice B is incorrect because asexual reproduction does not result in significantly greater variation; it produces genetically identical offspring. Choice D is incorrect because sexual reproduction involves two cells contributing genetic material, not one cell yielding all identical cells.

5. Which two bases are purines?

• A. Adenine (A)
• B. Cytosine (C)
• C. Thymine (T)
• D. Guanine (G)

Correct answer: A

Rationale: Adenine (A) and guanine (G) are the two bases that are purines. Purines are characterized by a double-ring structure containing two carbon rings, distinguishing them from pyrimidines. Adenine and guanine are purines because they possess this unique double-ring structure. Therefore, choices A and D, adenine and guanine, respectively, are the correct answers. Choices B and C, cytosine and thymine, are pyrimidines and do not exhibit the double-ring structure characteristic of purines.
