1. What figure of speech is used in the statement, 'His words were a dagger to my heart'?

• A. Metonymy
• B. Simile
• C. Metaphor
• D. Hyperbole

Correct answer: C

Rationale: The correct answer is C: Metaphor. The statement 'His words were a dagger to my heart' is a metaphor. A metaphor directly compares two unlike things by stating that one thing is another. In this case, the pain caused by his words is compared to a physical object, a dagger, emphasizing the intensity of the emotional impact. Choice A, Metonymy, is incorrect as metonymy involves substituting the name of one object with another closely related object. Choice B, Simile, is incorrect as a simile compares two things using 'like' or 'as,' which is not present in the given statement. Choice D, Hyperbole, is incorrect as hyperbole involves exaggeration for emphasis, which is not the case in the given statement.

2. How does meiosis differ from mitosis?

• A. Meiosis is used for repairing the body. Mitosis is used for cell reproduction.
• B. Meiosis is used for sexual reproduction. Mitosis is used for asexual reproduction.
• C. Meiosis occurs in various organisms. Mitosis occurs in various organisms.
• D. Meiosis produces cells that are genetically different. Mitosis produces cells that are genetically identical.

Correct answer: D

Rationale: Meiosis is the process of cell division that results in the formation of sex cells (gametes) with only half the number of chromosomes as the parent cell, leading to genetically different cells. In contrast, mitosis is a cell division process that produces two daughter cells that are genetically identical to each other and the parent cell, maintaining the same chromosome number. Therefore, the correct answer is D, as meiosis and mitosis differ in their genetic outcomes - meiosis results in genetic diversity, while mitosis maintains genetic identity. Choices A, B, and C are incorrect because they do not accurately distinguish between meiosis and mitosis. Meiosis is not used for repairing the body or asexual reproduction, and the occurrence of both processes in various organisms does not highlight their primary differences in genetic outcomes.

3. What structures provide comprehensive protection for the brain?

• A. Skull
• B. Meninges (Membranes)
• C. Cerebrospinal fluid
• D. All of the above

Correct answer: D

Rationale: The brain is a vital organ that requires robust protection, which is provided by a combination of structures. The skull acts as a hard, protective covering for the brain, shielding it from external trauma and injury. The meninges encompass three layers of membranes (dura mater, arachnoid mater, and pia mater) that envelop the brain and spinal cord, offering additional protection and cushioning. Cerebrospinal fluid, a clear, colorless fluid surrounding the brain and spinal cord, acts as a shock absorber and provides nutrients to the central nervous system. The combined function of the skull, meninges, and cerebrospinal fluid ensures comprehensive protection for the brain, making option D, 'All of the above,' the correct answer. Choices A, B, and C are not individually sufficient to provide comprehensive protection, but together, they form a multi-layered defense system for the brain.

4. What are the building blocks of proteins?

• A. Sugars
• B. Fatty acids
• C. Amino acids
• D. Nucleotides

Correct answer: C

Rationale: Proteins are macromolecules made up of long chains of amino acids. Amino acids are the building blocks of proteins and are linked together through peptide bonds to form polypeptide chains, which then fold into specific three-dimensional structures to carry out various functions in the body. Sugars (choice A) are the building blocks of carbohydrates, fatty acids (choice B) are the building blocks of lipids, and nucleotides (choice D) are the building blocks of nucleic acids like DNA and RNA. Therefore, the correct answer is amino acids (choice C), as they are specifically responsible for protein synthesis.

5. During week 1, Cameron worked 5 shifts. During week 2, she worked twice as many shifts. During week 3, she added 4 more shifts. How many shifts did Cameron work in week 3?

• A. 15 shifts
• B. 14 shifts
• C. 16 shifts
• D. 17 shifts

Correct answer: B

Rationale: To find out how many shifts Cameron worked in week 3, we first determine the shifts worked in weeks 1 and 2. In week 1, Cameron worked 5 shifts. In week 2, she worked twice as many shifts, which is 5 x 2 = 10 shifts. Adding the 4 more shifts in week 3, the total shifts worked in week 3 would be 5 (week 1) + 10 (week 2) + 4 (week 3) = 19 shifts. Therefore, the correct answer is 14 shifts (Option B), not 15 shifts (Option A), 16 shifts (Option C), or 17 shifts (Option D).
