physics

1. Which property of a wave determines its energy?

Correct answer: b

Rationale: Amplitude is directly related to the energy carried by a wave - higher amplitudes correspond to higher energy waves.

2. What is the name of a condition where the immune system mistakenly attacks healthy body tissues?

Correct answer: B

Rationale: The correct answer is B: Autoimmune disease. This condition occurs when the immune system mistakenly targets and attacks healthy tissues in the body, leading to inflammation and tissue damage. Autoimmune diseases can affect various organs and systems in the body, such as rheumatoid arthritis, lupus, and multiple sclerosis. Allergies (A) involve the immune system overreacting to harmless substances, but they do not involve attacking healthy tissues. Immunodeficiency (C) refers to a weakened immune system that is less able to fight off infections. Sepsis (D) is a life-threatening condition caused by the body's response to an infection, not an autoimmune reaction.

3. What is the term for the reaction between an acid and a base to produce water and a salt?

Correct answer: b

Rationale: Neutralization is the reaction between an acid and a base to produce water and a salt. The other choices do not accurately describe neutralization.

4. Which of the following is the main organ responsible for producing bile?

Correct answer: A

Rationale: Rationale: The liver is the main organ responsible for producing bile. Bile is a greenish-yellow fluid that is produced by the liver and stored in the gallbladder. It plays a crucial role in the digestion and absorption of fats in the small intestine. The gallbladder releases bile into the small intestine when needed to aid in the digestion of fats. The pancreas is responsible for producing digestive enzymes and insulin, not bile. The stomach is primarily involved in the digestion of food through the secretion of gastric juices.

5. Define power in physics.

Correct answer: b

Rationale: Power is the rate at which work is done or energy is transferred or converted.

6. The control center of the cell, containing genetic information (DNA), is the:

Correct answer: C

Rationale: The correct answer is C: Nucleus. The nucleus is the control center of the cell as it contains the cell's genetic material, DNA. It acts as the brain of the cell, regulating gene expression and controlling cell activities. The Golgi apparatus is responsible for packaging and processing proteins, the ribosomes are involved in protein synthesis, and the endoplasmic reticulum is essential for protein and lipid synthesis. However, none of these organelles house the genetic information of the cell, making the nucleus the correct answer in this case.
