1. Which of the following options correctly lists biology's hierarchical organizational system?

• A. Phylum, Kingdom, Class, Family, Order, Species, Genus
• B. Kingdom, Phylum, Class, Order, Family, Genus, Species
• C. Genus, Order, Kingdom, Class, Phylum, Species, Family
• D. Class, Phylum, Kingdom, Genus, Order, Family, Species

Correct answer: B

Rationale: The correct hierarchical organizational system in biology is Kingdom, Phylum, Class, Order, Family, Genus, and Species. This follows the mnemonic 'King Phillip Came Over For Good Soup.' Choice A is incorrect as it does not follow the correct hierarchical order. Choice C is incorrect as it starts with Genus, which is more specific and should come after Family. Choice D is incorrect as it does not follow the correct hierarchical order.

2. During which stage of mitosis does the nuclear envelope begin to disappear and the chromosomes start attaching to the spindle forming along the cell's axis?

• A. Prometaphase
• B. Metaphase
• C. Anaphase
• D. Prophase

Correct answer: A

Rationale: The correct answer is A, Prometaphase. During prometaphase, the nuclear envelope disintegrates, and chromosomes start attaching to spindle fibers. In metaphase, chromosomes align in the middle of the cell. Anaphase is characterized by the separation of sister chromatids, and prophase involves the condensation of chromosomes and the beginning of spindle formation.

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 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.

5. In which of the following does cellular respiration take place?

• A. Golgi apparatus
• B. Mitochondrion
• C. Chloroplast
• D. Ribosome

Correct answer: B

Rationale: The correct answer is B, Mitochondrion. Cellular respiration occurs in the mitochondria, where glucose is converted into energy through a series of metabolic processes. Choice A, Golgi apparatus, is incorrect as it is involved in modifying, sorting, and packaging proteins. Choice C, Chloroplast, is incorrect as it is the site of photosynthesis in plant cells, not cellular respiration. Choice D, Ribosome, is incorrect as it is responsible for protein synthesis, not energy production through cellular respiration.
