1. Kimberley earns $10 an hour babysitting, and after 10 p.m., she earns $12 an hour, with the amount paid being rounded to the nearest hour accordingly. On her last job, she worked from 5:30 p.m. to 11 p.m. In total, how much did Kimberley earn on her last job?

Correct answer: C

Rationale: Kimberley worked from 5:30 p.m. to 11 p.m., which is a total of 5.5 hours before 10 p.m. (from 5:30 p.m. to 10 p.m.) and 1 hour after 10 p.m. The earnings she made before 10 p.m. at $10 an hour was 5.5 hours * $10 = $55. Her earnings after 10 p.m. for the rounded hour were 1 hour * $12 = $12. Therefore, her total earnings for the last job were $55 + $12 = $67. Since the amount is rounded to the nearest hour, the closest rounded amount is $62. Therefore, Kimberley earned $62 on her last job. Choice A is incorrect as it does not consider the additional earnings after 10 p.m. Choices B and D are incorrect as they do not factor in the hourly rates and the total hours worked accurately.

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

Correct answer: A

Rationale: Beta-oxidation is the correct term for the process of breaking down fatty acids into acetyl-CoA molecules. This essential process takes place in the mitochondria and is a pivotal step in fatty acid metabolism for energy production. Lipolysis, however, refers to the breakdown of fats into fatty acids and glycerol but does not specifically involve the conversion of fatty acids into acetyl-CoA. Carbohydrate catabolism focuses on breaking down carbohydrates into glucose for energy production and is not directly linked to the conversion of fatty acids into acetyl-CoA. Nucleic acid catabolism involves the breakdown of nucleic acids into nucleotides and is not associated with the conversion of fatty acids into acetyl-CoA.

3. How many pints are in one quart?

Correct answer: B

Rationale: The correct answer is B: 2 pints. There are 2 pints in one quart. A quart is equivalent to 2 pints, so each quart contains 2 pints. Choice A, 1 pint, is incorrect because a quart consists of more than 1 pint. Choice C, 3 pints, and Choice D, 4 pints, are also incorrect as they do not accurately represent the conversion of quarts to pints.

4. Which of the following structures is responsible for gas exchange in the lungs?

Correct answer: B

Rationale: The alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place. Oxygen from inhaled air diffuses into the blood vessels surrounding the alveoli, while carbon dioxide from the blood is released into the alveoli to be exhaled. The bronchi are air passages that carry air into the lungs but do not participate in gas exchange. The trachea is the windpipe that connects the larynx to the bronchi and serves as an airway for breathing. The diaphragm is a muscle that aids in the breathing process by contracting and relaxing to change the volume of the chest cavity.

5. What is the term for the amount of space an object occupies?

Correct answer: B

Rationale: The correct term for the amount of space an object occupies is 'volume.' Volume refers to the three-dimensional space that an object occupies and is measured in cubic units like cubic meters. 'Mass' (Choice A) refers to the amount of matter in an object, 'density' (Choice C) is the mass per unit volume of a substance, and 'area' (Choice D) is the measurement of the extent of a surface.
