1. Which kingdom primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose?

• A. Animalia
• B. Fungi
• C. Plantae
• D. Protista

Correct answer: C

Rationale: Rationale: A) Animalia consists of multicellular organisms that lack cell walls and are heterotrophic. B) Fungi are multicellular organisms with cell walls made of chitin and are heterotrophic. C) Plantae primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose. This description fits plants. D) Protista is a diverse kingdom that includes unicellular and multicellular organisms with varying characteristics, but it does not primarily consist of multicellular, photosynthetic organisms with cell walls made of cellulose.

2. A substance that can donate a hydroxide ion (OH-) in solution is classified as a:

• A. Salt
• B. Base
• C. Neutral compound
• D. Dehydrating agent

Correct answer: B

Rationale: Bases accept protons (H+) and can donate hydroxide ions

3. How is power related to work and time?

• A. Power = Work ÷ Time
• B. Power = Work × Time
• C. Power = Work + Time
• D. Power = Work - Time

Correct answer: a

Rationale: Power is calculated as the amount of work done or energy transferred per unit of time.

4. Neurons, the functional units of the nervous system, belong to which tissue type?

• A. Epithelial tissue
• B. Connective tissue
• C. Muscle tissue
• D. Nervous tissue

Correct answer: D

Rationale: The correct answer is D: Nervous tissue. Neurons are specialized cells that transmit nerve impulses and are the primary components of the nervous system. Nervous tissue is made up of neurons and supporting cells called neuroglia. Neurons are responsible for processing and transmitting information throughout the body, making them a crucial part of the nervous system. Epithelial tissue (A) is primarily involved in covering and lining surfaces, connective tissue (B) supports and connects other tissues, and muscle tissue (C) is responsible for movement. Therefore, neurons belong to nervous tissue, which is specialized for communication and coordination within the body.

5. What is the main function of the endoplasmic reticulum (ER) in the cell?

• A. To synthesize and transport proteins and lipids
• B. To package and transport proteins
• C. To break down macromolecules
• D. To store genetic material

Correct answer: A

Rationale: Rationale: A) The endoplasmic reticulum (ER) is a network of membranes within the cell that plays a crucial role in protein and lipid synthesis. It consists of two types: rough ER, which is studded with ribosomes and involved in protein synthesis, and smooth ER, which is involved in lipid synthesis and detoxification. The ER also plays a role in transporting these synthesized proteins and lipids to other parts of the cell or outside the cell. B) While the ER is involved in packaging proteins, the main function is not solely to package and transport proteins. This function is more associated with the Golgi apparatus. C) Breaking down macromolecules is primarily the function of lysosomes, which are membrane-bound organelles containing enzymes for digestion. D) Storing genetic material is the function of the nucleus, which houses the cell's DNA. The ER is not involved in storing

6. What is the significance of cell division?

• A. Growth and repair of tissues
• B. Sexual reproduction
• C. Genetic diversity
• D. All of the above

Correct answer: D

Rationale: Cell division is a fundamental process that is essential for the growth, repair, and reproduction of all living organisms. It plays a crucial role in ensuring that organisms maintain their proper size and shape, and it allows for the replacement of damaged or worn-out cells. Cell division is also essential for sexual reproduction, as it is the process by which haploid gametes (sex cells) are produced. These gametes fuse during fertilization to form a diploid zygote, which ultimately gives rise to a new organism.
