physics

1. What is the SI unit of measurement for acceleration?

Correct answer: d

Rationale: Acceleration is measured in meters per second squared (m/s²) in the SI unit system.

2. Which element is found in water and is crucial for biological functions like nerve impulses and muscle contraction?

Correct answer: A

Rationale: Sodium plays a key role in maintaining electrolyte balance and transmitting nerve impulses, affecting both muscles and nerves

3. 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.

4. Identify the verb in the following sentence: The dog chased the fluffy squirrel around the oak tree.

Correct answer: B

Rationale: Verbs express actions or states of being. In this sentence, "chased" describes what the dog did.

5. he shimmering image of water seen on a hot road is a well-known example of:

Correct answer: B

Rationale: The shimmering image of water seen on a hot road is a classic example of refraction. Refraction occurs when light waves pass from one medium to another, causing them to change direction due to the change in speed. In this scenario, the air above the road is hotter than the air closer to the ground, creating different densities of air which causes light to bend and distort, giving the illusion of water. Reflection, on the other hand, is the bouncing back of light waves from a surface, interference involves the superposition of two or more waves, and polarization is the orientation of light waves in a specific direction. Therefore, option B, refraction, is the correct answer in this case.

6. The rigid structure that provides shape and support to plant cells is called the:

Correct answer: A

Rationale: The correct answer is A: Cell wall. The cell wall is a rigid structure found in plant cells, providing support and shape to the cell. It is composed mainly of cellulose, a tough and fibrous substance that helps plants maintain their structure. The plasma membrane, option B, is a semi-permeable membrane that surrounds the cell and regulates the passage of substances in and out of the cell. The nucleus, option C, is the control center of the cell that contains genetic material. Cytoplasm, option D, is the jelly-like substance that fills the cell and houses organelles. In this context, the function of providing shape and support points specifically to the cell wall, making it the correct choice.
