Biology

1. Differentiate between genotype and phenotype in the context of gene expression.

Correct answer: B

Rationale: Rationale: - Genotype refers to the genetic makeup of an organism, including all the genes and alleles it possesses. - Phenotype, on the other hand, refers to the observable physical characteristics or traits of an organism, which result from the interaction between its genotype and the environment. - While genotype represents the genetic potential or range of traits that an organism can express, phenotype reflects the actual expression of specific traits. - Therefore, option B correctly captures the distinction between genotype and phenotype in the context of gene expression.

2. 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.

3. What is the difference between emphysema and chronic bronchitis, both chronic obstructive pulmonary diseases (COPD)?

Correct answer: A

Rationale: The correct answer is A. Emphysema and chronic bronchitis are both types of COPD, but they have distinct characteristics. Emphysema is characterized by the destruction of the alveoli in the lungs, which impairs the exchange of oxygen and carbon dioxide. This damage to the alveoli leads to difficulty breathing and decreased lung function. On the other hand, chronic bronchitis involves inflammation and narrowing of the airways, leading to excessive mucus production and a persistent cough. While both conditions are chronic and progressive, emphysema primarily affects the alveoli, while chronic bronchitis primarily affects the airways. Understanding these differences is crucial for appropriate diagnosis and management of COPD.

4. A ball is rolling across the floor and comes to a stop on its own. What force caused the ball to stop?

Correct answer: C

Rationale: In the absence of other forces, air resistance will gradually slow down the ball until it stops.

5. What is the term for the distance between the center of a lens or curved mirror and its focal point?

Correct answer:

Rationale: The focal length of a lens or curved mirror is the distance between its center and the focal point, where parallel light rays converge or appear to diverge from.

6. A spring is stretched and released, causing an object attached to it to oscillate. What determines the frequency of the oscillations?

Correct answer: B

Rationale: The stiffness of the spring. Frequency depends on the spring constant and the mass, but the mass term cancels out in the formula for simple harmonic motion, leaving only the spring constant.
