Mathematics

1. 12 is a/an:

Correct answer: A

Rationale: Even numbers are integers divisible by 2 without a remainder. Since 12 divided by 2 equals 6 with no remainder, 12 is even.

2. The passage implies that achieving energy sustainability requires...

Correct answer: B

Rationale: The passage emphasizes the need for both increasing renewable energy and managing its fluctuations, suggesting B as the key to sustainability.

3. The innate immune system provides:

Correct answer: A

Rationale: The correct answer is A: 'Nonspecific, immediate defense against pathogens.' The innate immune system is the body's first line of defense against pathogens and provides a rapid, nonspecific response. It includes physical barriers like the skin, chemical barriers like stomach acid, and cellular responses like inflammation. This system does not involve memory cells or provide long-term immunity, which are characteristics of the adaptive immune system. Therefore, option A accurately describes the function of the innate immune system as a quick and nonspecific defense mechanism.

4. What is the term for a hydrocarbon chain with no double or triple bonds between carbon atoms?

Correct answer: A

Rationale: A saturated hydrocarbon chain has only single bonds between carbon atoms. The other choices are associated with unsaturation or aromaticity.

5. A patient needs to take 2 tablets for every 30 pounds of body weight. If they weigh 150 pounds, how many tablets should they take?

Correct answer: A

Rationale: Divide the patient's weight (150 pounds) by the ratio denominator (30 pounds/tablet) to get 5 tablets.

6. The phrase "survival of the fittest" refers to:

Correct answer: B

Rationale: Rationale: The phrase "survival of the fittest" is often associated with the concept of natural selection, which was proposed by Charles Darwin. Natural selection is the process by which organisms that are best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation. This process does not necessarily favor the most complex anatomical structures (option A) or the strongest and most aggressive individuals (option D). Instead, it emphasizes the importance of adaptations that enhance an organism's ability to survive and reproduce in a specific environment. Option C is incorrect because natural selection results in differential reproductive success based on an organism's traits, meaning that not all organisms have an equal probability of survival and reproductive success.
