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. Asexual reproduction is a type of reproduction by which offspring arise from:

• A. Two identical cells
• B. A single cell
• C. Two cells
• D. Four daughter cells

Correct answer: B

Rationale: Asexual reproduction is a type of reproduction where a single parent cell divides to produce genetically identical offspring. The correct answer is 'B: A single cell' because asexual reproduction does not involve the fusion of two cells. Choice A ('Two identical cells') is incorrect because asexual reproduction does not involve two cells. Choice C ('Two cells') is incorrect because asexual reproduction typically involves only one parent cell. Choice D ('Four daughter cells') is incorrect because asexual reproduction does not necessarily involve the production of four daughter cells.

3. 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.

4. Where can ribosomes be found inside a cell?

• A. Attached to the endoplasmic reticulum (ER) and in the cytoplasm
• B. Within the cellular membrane
• C. Attached to the Golgi apparatus and in the cytoplasm
• D. Within the nucleus

Correct answer: A

Rationale: Ribosomes can be found attached to the endoplasmic reticulum (ER) or free-floating in the cytoplasm. The correct answer is A because ribosomes are responsible for synthesizing proteins and are commonly found on the ER or in the cytoplasm. Choice B is incorrect because ribosomes are not typically located within the cellular membrane. Choice C is incorrect as ribosomes are not attached to the Golgi apparatus; instead, they are involved in protein synthesis. Choice D is incorrect as ribosomes are not found within the nucleus but rather in the cytoplasm or attached to the ER.

5. Who discovered the basic principles of genetics using garden peas?

• A. Curie
• B. Mendel
• C. Hawking
• D. Galileo

Correct answer: B

Rationale: The correct answer is B, Mendel. Gregor Mendel is known as the father of genetics for his groundbreaking work with pea plants. He discovered the basic principles of heredity through his experiments, establishing the foundation of modern genetics. Choice A, Curie, is incorrect as Marie Curie was a physicist and chemist known for her pioneering research on radioactivity. Choice C, Hawking, is incorrect as Stephen Hawking was a theoretical physicist known for his work on black holes and cosmology. Choice D, Galileo, is incorrect as Galileo Galilei was an astronomer and physicist renowned for his contributions to the scientific revolution, particularly in astronomy.
