1. What is the process of cells dividing to produce new cells called?

Correct answer: A

Rationale: Rationale: A) Cell division is the process by which a parent cell divides into two or more daughter cells, allowing for growth, repair, and reproduction in living organisms. This process ensures that genetic material is accurately passed on to the new cells. B) Cell differentiation refers to the process by which cells become specialized to perform specific functions in an organism. While cell division is essential for cell differentiation, they are distinct processes. C) Cell growth is the increase in size or mass of a cell, which can occur before or after cell division. While cell growth is a component of the cell division process, it is not the primary process of cells dividing to produce new cells. D) Cell regeneration is the process by which damaged or lost cells are replaced by new cells. While cell division is involved in cell regeneration, it specifically refers to the overall process of cells dividing to produce new cells. Therefore, the most appropriate answer to the ques

2. What is the name for the process where a solid changes directly into a gas?

Correct answer: B

Rationale: Sublimation occurs when a solid directly transforms into a gas without passing through a liquid phase.

3. How does an increase in surface area affect the force of friction between two surfaces?

Correct answer: b

Rationale: Increasing surface area reduces the force per unit area, decreasing friction.

4. The process of mixing two or more substances to form a heterogeneous mixture is called:

Correct answer: C

Rationale: Mixing results in a heterogeneous mixture where the components are physically distinguishable, unlike solutions where everything dissolves uniformly

5. A birthday party hat has a cone-shaped top with a radius of 5cm and a height of 12cm. What is its volume?

Correct answer: C

Rationale: Use the formula for volume of a cone: (1/3) * π * (radius)^2 * height. Substitute the values: (1/3) * π * (5cm)^2 * 12cm ≈ 150 cu cm.

6. In the process of cellular respiration, glucose is broken down to produce energy. What is the main waste product released?

Correct answer: B

Rationale: The correct answer is B: Carbon dioxide. During cellular respiration, glucose is broken down in the presence of oxygen to produce energy in the form of ATP. One of the main waste products released in this process is carbon dioxide. Carbon dioxide is a byproduct of the metabolic reactions occurring in cells and is expelled from the body through exhalation. Water is also produced during cellular respiration, but it is not the main waste product released. Oxygen is required for cellular respiration to occur, and protein is a macromolecule and not a waste product of cellular respiration.
