1. Identify the INCORRECT function of the liver.

• A. Bile production to aid digestion.
• B. Synthesis of blood proteins, such as albumin.
• C. Storage of glucose for energy regulation.
• D. Filtration of waste products from the blood.

Correct answer: D

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. What is the formula to calculate kinetic energy?

• A. Kinetic Energy = Mass × Velocity
• B. Kinetic Energy = Force × Distance
• C. Kinetic Energy = Power × Time
• D. Kinetic Energy = Potential Energy ÷ Time

Correct answer: A

Rationale: Kinetic energy is the energy an object possesses due to its motion. The formula to calculate kinetic energy is KE = 0.5 × mass × velocity^2, which can also be written as KE = mass × (velocity)^2. Therefore, the correct formula is Kinetic Energy = Mass × Velocity. Choice B is incorrect because it represents the work formula. Choice C is incorrect as it represents the formula for work done. Choice D is incorrect as it does not accurately represent the formula for calculating kinetic energy.

3. What is a reaction between an acid and a base known as?

• A. Precipitation
• B. Neutralization
• C. Oxidation-reduction
• D. Photolysis

Correct answer: B

Rationale: The correct answer is B: Neutralization. When an acid and a base react, they neutralize each other's properties, resulting in the formation of water and a salt. Choice A, 'Precipitation,' refers to the formation of a solid from a solution during a chemical reaction. Choice C, 'Oxidation-reduction,' involves the transfer of electrons between reactants. Choice D, 'Photolysis,' is a reaction where a compound is broken down into smaller components by light energy. Therefore, the most appropriate term for a reaction between an acid and a base is neutralization.

4. What are apocrine and eccrine?

• A. Blood vessel
• B. Cell types
• C. Hormones
• D. Sweat glands

Correct answer: D

Rationale: Apocrine and eccrine refer to types of sweat glands in the human body. Apocrine sweat glands are larger and located in areas like the armpits and groin, producing a thicker secretion that can be associated with body odor. Eccrine sweat glands are found throughout the skin and are responsible for regulating body temperature through the production of sweat. Understanding the functions and locations of these glands is essential in comprehending the body's thermoregulation processes.

5. What is the term for the process of bone formation and breakdown?

• A. Ossification
• B. Resorption
• C. Remodeling
• D. All of the above

Correct answer: C

Rationale: The correct term for the process of bone formation and breakdown is remodeling. Ossification specifically refers to bone formation, while resorption pertains to bone breakdown. Remodeling encompasses both processes, as it involves the continuous cycle of bone formation and resorption to maintain bone strength and structure. Choice A, 'Ossification,' is incorrect as it only refers to bone formation. Choice B, 'Resorption,' is incorrect as it only refers to bone breakdown. Choice D, 'All of the above,' is incorrect as it includes terms that are not comprehensive of both bone formation and breakdown.
