1. What best describes Samuel's sample size?

• A. The sample is biased because it has firsthand experience.
• B. The sample contains too few members to draw meaningful conclusions.
• C. The sample contains too many members to make specific claims.
• D. The sample is unbiased and of appropriate size.

Correct answer: B

Rationale: Samuel's sample size of 24 students is too small to draw generalizable conclusions about a larger population. While his observations are based on firsthand experience, the sample size is inadequate to make meaningful claims about the relationship between parental involvement and academic success for all students. Choice A is incorrect because bias is not related to sample size but rather the way data is collected. Choice C is incorrect as having too many members would not hinder understanding specifics, but rather provide a more comprehensive view. Choice D is incorrect as the sample size is too small to be considered appropriately sized for making broad claims.

2. Based on an examination of word parts, which of the following words means 'above the kidney'?

• A. Interrenal
• B. Subrenal
• C. Intrarenal
• D. Suprarenal

Correct answer: D

Rationale: The correct answer is 'Suprarenal.' Breaking down the word parts, 'supra-' means above, and '-renal' pertains to the kidney. Therefore, 'Suprarenal' means above the kidney. Choice A, 'Interrenal,' is incorrect as 'inter-' means between or among. Choice B, 'Subrenal,' is incorrect as 'sub-' means below. Choice C, 'Intrarenal,' is incorrect as 'intra-' means within or inside.

3. How many electrons are typically found in each shell of a neutral aluminum atom with 13 electrons in its electron cloud?

• A. 6 in the first shell, 7 in the second shell
• B. 2 in the first shell, 11 in the second shell
• C. 2 in the first shell, 8 in the second shell, 3 in the third shell
• D. 3 in the first shell, 5 in the second shell, 5 in the third shell

Correct answer: C

Rationale: In a neutral aluminum atom with 13 electrons, the electron distribution typically follows the electron shell filling order based on the Aufbau principle. The first shell can hold a maximum of 2 electrons, the second shell can hold up to 8 electrons, and the third shell can hold up to 8 electrons as well. Therefore, the distribution would be 2 electrons in the first shell, 8 electrons in the second shell, and 3 electrons in the third shell, totaling 13 electrons. Choice A is incorrect as it exceeds the maximum number of electrons the shells can hold. Choice B is incorrect as it does not distribute the electrons correctly among the shells. Choice D is incorrect as it also does not distribute the electrons correctly among the shells.

4. Of the individuals described below, who seems like the best applicant for the roommate advertisement?

• A. Frances is a research assistant in the science department and owns a Yorkshire terrier.
• B. Adelaide works in the humanities department and is seeking a three-month rental.
• C. Cosette is allergic to cigarette smoke and requires a quiet place to study.
• D. Felix is a graduate student in the history department and does not own a car.

Correct answer: C

Rationale: The best applicant for the roommate advertisement is Cosette. The ad specifies that the current occupants are quiet, the house is clean/smoke-free, and no pets are allowed. Cosette is allergic to cigarette smoke, indicating she is a non-smoker and prefers a smoke-free environment. She also needs a quiet place to study, aligning with the quiet environment mentioned in the ad. Additionally, the ad prefers long-term applicants, and Cosette's need for a quiet place to study implies she will likely remain for an extended period. Frances owning a Yorkshire terrier goes against the ad's 'no pets' policy. Adelaide seeking a three-month rental does not align with the preference for long-term applicants. Felix not owning a car is not relevant to the criteria set by the ad.

5. Which of the following is the region of the brain that controls and regulates autonomic functions such as respiration, digestion, and heart rate?

• A. cerebellum
• B. medulla oblongata
• C. temporal lobe
• D. cerebral cortex

Correct answer: B

Rationale: The medulla oblongata is the correct answer. It is the region of the brain located at the base of the brainstem responsible for regulating autonomic functions such as respiration, digestion, and heart rate. These functions are essential for maintaining life. The cerebellum (Option A), temporal lobe (Option C), and cerebral cortex (Option D) do not control these autonomic functions. The cerebellum is mainly involved in coordination and balance, the temporal lobe is associated with memory and hearing, and the cerebral cortex is responsible for higher brain functions like thinking and decision-making.
