1. During exercise, heart rate increases to deliver more oxygen to the body's tissues. What other cardiovascular response also increases?

Correct answer: C

Rationale: During exercise, the cardiovascular response includes an increase in blood flow to the muscles to deliver more oxygen and nutrients needed for energy production. This helps to support the increased demand for oxygen and nutrients by the working muscles. Blood pressure typically increases during exercise to help facilitate this increased blood flow to the muscles. Additionally, blood vessel diameter may widen (vasodilation) to allow for more blood flow, rather than narrow. Blood viscosity does not typically thicken during exercise.

2. Which of the following phases of mitosis is characterized by the separation of sister chromatids and their movement to opposite poles?

Correct answer: B

Rationale: During anaphase of mitosis, the sister chromatids, which are duplicated copies of a chromosome, separate and move towards opposite poles of the cell. This movement is facilitated by the shortening of microtubules attached to the chromatids. As a result, each pole of the cell receives a complete set of chromosomes, ensuring that the daughter cells produced after cell division will have the correct number of chromosomes. Metaphase is characterized by the alignment of chromosomes at the cell's equator, not their separation. Telophase is the phase following anaphase, where the separated chromatids reach the opposite poles and nuclear envelopes start to form around them. Cytokinesis is the final stage of cell division, where the cytoplasm is divided to form two separate daughter cells.

3. What is true about a strong academic thesis?

Correct answer: B

Rationale: A strong thesis statement is a crucial element in academic writing as it clearly states the argument that will be supported throughout the paper. This statement serves as a roadmap for the reader to understand the main point of the paper. Choice A is incorrect because a strong thesis is not necessarily endorsed by a professor but is based on the writer's perspective. Choice C is incorrect as a thesis should reflect the writer's position, not necessarily the opinions of most people. Choice D is incorrect because a strong thesis should invite critical thinking and argumentation, rather than being immune to reasonable counterarguments.

4. What is 0.04 liters converted to milliliters?

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. So, to convert 0.04 liters to milliliters, you would multiply 0.04 by 1,000, giving you 40 milliliters. This means that choice A, '40 ml', is the correct answer. Choices B, C, and D are incorrect because they do not correctly convert liters to milliliters. Choice B, '4 ml', is incorrect as it is 10 times smaller than the correct conversion. Choice C, '400 ml', is incorrect as it is 10 times larger than the correct conversion. Choice D, '0.4 ml', is incorrect as it is one-tenth of the correct conversion.

5. What is the equivalent of 255.0 pounds in kilograms (1 kg = 2.205 lbs)?

Correct answer: D

Rationale: To convert pounds to kilograms, you need to divide the weight in pounds by 2.205 (1 kg = 2.205 lbs). Therefore, 255.0 pounds divided by 2.205 equals 115.6 kilograms. This results in choice D being the correct answer. Choices A, B, and C are incorrect as they do not reflect the accurate conversion calculation from pounds to kilograms.
