1. What property of matter refers to the amount of space occupied by an object?

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

Correct answer: b

Rationale: Volume measures the amount of space occupied by an object.

2. What is the process of breaking down fatty acids into acetyl-CoA, a key molecule in cellular respiration, called?

• A. Beta-oxidation
• B. Lipolysis
• C. Carbohydrate catabolism
• D. Nucleic acid catabolism

Correct answer: A

Rationale: Rationale: A) Beta-oxidation is the process of breaking down fatty acids into acetyl-CoA molecules. This process occurs in the mitochondria and is a crucial step in fatty acid metabolism for energy production. B) Lipolysis is the breakdown of fats into fatty acids and glycerol, but it does not specifically refer to the conversion of fatty acids into acetyl-CoA. C) Carbohydrate catabolism involves the breakdown of carbohydrates into glucose for energy production and is not directly related to the conversion of fatty acids into acetyl-CoA. D) Nucleic acid catabolism refers to the breakdown of nucleic acids into nucleotides and does not involve the conversion of fatty acids into acetyl-CoA.

3. What does the term "net force" refer to in physics?

• A. Total force acting on an object
• B. Force due to gravity
• C. Force in motion
• D. Force of friction

Correct answer: a

Rationale: Net force is the vector sum of all forces acting on an object.

4. What happens to the concentration of hydrogen ions (\([H^+]\)) in a solution as the pH increases?

• A. Increases
• B. Decreases
• C. Remains constant
• D. Becomes neutral

Correct answer: B

Rationale: As the pH increases, the concentration of hydrogen ions decreases. The relationship is inversely proportional

5. Which of Mendel's Laws states that alleles for a gene segregate during gamete formation?

• A. Law of Independent Assortment
• B. Law of Segregation
• C. Law of Dominance
• D. Law of Probability

Correct answer: B

Rationale: Rationale: The Law of Segregation, proposed by Gregor Mendel, states that alleles for a gene segregate during gamete formation. This means that each parent passes on only one allele for each gene to their offspring. This law explains how genetic diversity is maintained and how different combinations of alleles are generated in offspring. The Law of Independent Assortment (option A) states that alleles of different genes assort independently of each other during gamete formation. The Law of Dominance (option C) states that one allele can be dominant over another allele, affecting the phenotype. The Law of Probability (option D) is a general concept that describes the likelihood of a particular event occurring.

6. Which energy conversion occurs in a solar cell?

• A. Electrical energy to light energy
• B. Chemical energy to electrical energy
• C. Solar energy to thermal energy
• D. Solar energy to electrical energy

Correct answer: d

Rationale: Solar cells convert solar energy (sunlight) directly into electrical energy.
