1. Where can you typically find the thesis statement of an essay?

• A. Conclusion
• B. Introduction
• C. Body paragraph
• D. Bibliography

Correct answer: B

Rationale: The thesis statement of an essay is usually located in the introduction. This is where the author establishes the main idea or argument that will be developed throughout the essay. The conclusion (Choice A) summarizes the main points and restates the thesis but does not introduce it. Body paragraphs (Choice C) provide supporting details and arguments, while the bibliography (Choice D) lists the sources used in the essay, not the thesis statement.

2. Follow these instructions in chronological order to transform the word into something new. What new word has been spelled?

• A. TON
• B. THIN
• C. TIN
• D. TAN

Correct answer: C

Rationale: To transform the word LOATHING into something new, we need to follow the instructions in chronological order, which is to remove letters. Starting with L-O-A-T-H-I-N-G, if we remove the letters in the order given, we are left with T-I-N, which spells the word 'TIN.' This makes choice C the correct answer. Choices A, B, and D do not follow the specific sequence of removing letters from the original word LOATHING, so they are incorrect.

3. Which structure contains the genetic material (DNA) of the cell?

• A. Cytoplasm
• B. Nucleus
• C. Cell wall (only present in plant cells)
• D. Golgi apparatus

Correct answer: B

Rationale: The nucleus is the organelle that contains the genetic material (DNA) of the cell. It acts as the control center of the cell, regulating gene expression and coordinating cellular activities. The cytoplasm is the fluid-filled space within the cell where organelles are suspended, but it does not contain the genetic material. The cell wall is a rigid structure found in plant cells that provides support and protection, but it does not house the DNA. The Golgi apparatus is involved in processing and packaging proteins for secretion, but it does not contain the genetic material of the cell.

4. Which of the following is the correct simplification of the expression below? 12 ÷ 3 × 4 - 1 + 23

• A. 6
• B. 21
• C. 38
• D. 23

Correct answer: C

Rationale: The correct order of operations dictates solving division and multiplication before addition and subtraction. Therefore, following the order: (12 ÷ 3) × 4 - 1 + 23 = 4 × 4 - 1 + 23 = 16 - 1 + 23 = 38. Choice A (6) results from adding and subtracting before division and multiplication. Choice B (21) results from incorrect placement of parentheses. Choice D (23) is the last number in the expression and does not reflect the cumulative result of the operations.

5. What is the main function of calcitonin, a hormone produced by the thyroid gland?

• A. Stimulate metabolism and heat production
• B. Increase calcium absorption from the intestines
• C. Enhance bone growth and development
• D. Lower blood calcium levels

Correct answer: D

Rationale: Calcitonin is a hormone produced by the thyroid gland that primarily functions to lower blood calcium levels. It achieves this by inhibiting bone breakdown and promoting calcium excretion by the kidneys. Therefore, the correct answer is D as it reflects the main role of calcitonin in calcium homeostasis. Choices A, B, and C are incorrect as they do not align with the primary function of calcitonin. Calcitonin does not stimulate metabolism and heat production (Choice A), increase calcium absorption from the intestines (Choice B), or enhance bone growth and development (Choice C).
