1. What is the process of cells restoring damaged or lost tissues called?

Correct answer: D

Rationale: Rationale: A) Cell division refers to the process by which a cell divides into two daughter cells. B) Cell differentiation is the process by which cells become specialized for specific functions. C) Cell growth is the increase in cell size or number. D) Cell regeneration is the process of cells restoring damaged or lost tissues by replacing or repairing the damaged cells. This process is essential for healing wounds and maintaining tissue integrity.

2. What is the final phase of mitosis?

Correct answer: B

Rationale: Telophase is indeed the final phase of mitosis. During telophase, the chromosomes have reached opposite poles of the cell, the nuclear envelope is re-forming around the separated sister chromatids, and cytokinesis may also occur, leading to the division of the cell into two daughter cells. Choice A, Prophase, is incorrect as it is the initial phase of mitosis where chromatin condenses into chromosomes. Choice C, Anaphase, is incorrect as it is the phase where sister chromatids separate and move towards opposite poles. Choice D, Metaphase, is incorrect as it is the phase where chromosomes align at the cell's equator before separating.

3. The framework of bones, cartilage, ligaments, and tendons that provides structure, support, and facilitates movement is part of the:

Correct answer: B

Rationale: The skeletal system consists of bones, cartilage, ligaments, and tendons that work together to provide structure, support, protection for internal organs, and facilitate movement. It is responsible for supporting the body's framework and protecting vital organs. The muscular system (option A) consists of muscles that work with the skeletal system to produce movement but does not include bones, cartilage, ligaments, and tendons. The nervous system (option C) is responsible for transmitting signals throughout the body to control movement and other functions. The endocrine system (option D) is a collection of glands that produce hormones to regulate various bodily functions but is not primarily involved in structure, support, and movement as the skeletal system is.

4. What is the initial step of the scientific method?

Correct answer: B

Rationale: The first step of the scientific method is to make observations. This involves collecting data and information about a specific phenomenon or problem. Observations serve as the basis for developing a question to be explored further. Forming a hypothesis (Choice A) comes after making observations, as the hypothesis is an educated guess to explain the observations. Analyzing data (Choice C) occurs later in the scientific method after data has been collected and experiments conducted. Forming a question (Choice D) is a crucial step but typically follows observations in the scientific process.

5. Which of the following substances is an example of an acidic gas?

Correct answer: C

Rationale: The correct answer is C, Sulfur dioxide (SO₂). Sulfur dioxide is an acidic gas because when dissolved in water, it forms sulfurous acid, which imparts acidic properties. Nitrogen (N₂), carbon dioxide (CO₂), and oxygen (O₂) are not considered acidic gases. Nitrogen is a neutral gas, carbon dioxide forms a weakly acidic solution when dissolved in water, and oxygen is a neutral gas.
