1. Which of the following options correctly lists the five stages of mitosis in order from beginning to end?

A. Prophase, Prometaphase, Telophase, Metaphase, Anaphase
B. Prophase, Prometaphase, Metaphase, Anaphase, Telophase
C. Metaphase, Anaphase, Prophase, Prometaphase, Telophase
D. Metaphase, Telophase, Anaphase, Prophase, Prometaphase

Correct answer: B

Rationale: The correct order of the stages of mitosis is Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. Choice A is incorrect because it has Anaphase and Metaphase in the wrong order. Choice C is incorrect as it starts with Metaphase, which is not the first stage of mitosis. Choice D is incorrect as it also has the stages in the wrong order, and it starts with Metaphase, which is incorrect.

2. What are the two primary products of photosynthesis?

A. Sugar and oxygen
B. Sugar and carbon dioxide
C. Oxygen and nitrogen
D. Nitrogen and carbon dioxide

Correct answer: A

Rationale: The correct answer is A: Sugar and oxygen. During photosynthesis, plants convert carbon dioxide and water into glucose (sugar) and oxygen using sunlight. Choice B, 'Sugar and carbon dioxide,' is incorrect because carbon dioxide is one of the reactants, not a product. Choice C, 'Oxygen and nitrogen,' is incorrect as nitrogen is not a direct product of photosynthesis. Choice D, 'Nitrogen and carbon dioxide,' is incorrect because nitrogen is not a product of photosynthesis, and carbon dioxide is a reactant.

3. What is the liquid found inside the cell?

A. Plasma membrane
B. Cilia
C. Cytoplasm
D. Cytosol

Correct answer: D

Rationale: The correct answer is D, Cytosol. Cytosol is the liquid component of the cytoplasm where various cellular processes occur. Choices A, B, and C are incorrect because the plasma membrane is the outer boundary of the cell, cilia are hair-like structures on the cell surface, and cytoplasm is the jelly-like substance that contains organelles within the cell, not the liquid inside the cell.

4. Which two items react during cellular respiration?

A. Glucose and water
B. Carbon dioxide and water
C. Carbon dioxide and oxygen
D. Glucose and oxygen

Correct answer: D

Rationale: The correct answer is D: Glucose and oxygen. During cellular respiration, glucose and oxygen react in the presence of enzymes to produce carbon dioxide, water, and energy in the form of ATP. Choice A (Glucose and water) is incorrect because water is a product of cellular respiration, not a reactant. Choice B (Carbon dioxide and water) is incorrect as carbon dioxide is produced during cellular respiration, not a reactant. Choice C (Carbon dioxide and oxygen) is incorrect because oxygen is a reactant in cellular respiration, not a product.

5. What percentage of the offspring of the parents is predicted to have a cleft chin?

A. 25%
B. 50%
C. 0%
D. 75%

Correct answer: A

Rationale: When one parent carries the recessive gene for a cleft chin and the other does not, there is a 25% chance of the offspring inheriting the cleft chin. This is due to the fact that the trait follows a simple Mendelian inheritance pattern, where the offspring would need to inherit the recessive gene from both parents to express the trait. Therefore, 25% of the offspring are predicted to have a cleft chin. Choices B, C, and D are incorrect because the likelihood of inheriting a cleft chin in this specific scenario is 25%, not 50%, 0%, or 75%.
