1. Discern the INCORRECT function of the liver.

• A. Bile production, aiding digestion.
• B. Blood protein synthesis, such as albumin.
• C. Glucose storage for energy regulation.
• D. Filtration of waste products from the blood.

Correct answer: D

Rationale: Rationale: A) Correct - The liver produces bile, which aids in the digestion and absorption of fats in the small intestine. B) Correct - The liver is responsible for synthesizing blood proteins, including albumin, which helps maintain osmotic pressure in the blood. C) Correct - The liver stores glucose in the form of glycogen and helps regulate blood sugar levels by releasing glucose when needed. D) Incorrect - The liver does not filter waste products from the blood. Instead, the kidneys are responsible for filtering waste products from the blood and excreting them in the form of urine.

2. In the cardiovascular system, what is the primary function of red blood cells?

• A. To transport oxygen throughout the body.
• B. To fight infection and disease.
• C. To help regulate blood clotting.
• D. To remove waste products from the body.

Correct answer: A

Rationale: The correct answer is A: 'To transport oxygen throughout the body.' Red blood cells contain hemoglobin, a protein that binds to oxygen in the lungs and carries it to tissues throughout the body. This process is essential for cellular respiration, where oxygen is used to produce energy. Red blood cells do not fight infection (B), regulate blood clotting (C), or remove waste products (D); those functions are carried out by other components of the immune and circulatory systems.

3. What is the scientific unit used to measure the radioactivity of a substance?

• A. Becquerel (Bq)
• B. Joule (J)
• C. Newton (N)
• D. Kelvin (K)

Correct answer: A

Rationale: Becquerel measures the number of nuclear decays per second in a radioactive sample.

4. What type of particle carries no charge and mediates the strong nuclear force between protons and neutrons?

• A. Electron
• B. Photon
• C. Gluon
• D. Neutrino

Correct answer: C

Rationale: Gluons are the force carriers of the strong nuclear force, holding protons and neutrons together within the nucleus.

5. Identify the appositive in the following sentence: "My favorite author, Agatha Christie, wrote many detective novels."

• A. favorite

6. What property of a substance remains constant regardless of the amount of the substance present?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: c

Rationale: Density remains constant for a specific substance regardless of the quantity present. It's the mass per unit volume and remains the same for a substance.
