1. Which of the following algebraic equations correctly represents the sentence 'Four more than a number, x, is 2 less than 1/3 of another number, y'?

• A. x + 4 = (1/3)y - 2
• B. 4x = 2 - (1/3)y
• C. 4 - x = 2 + (1/3)y
• D. x + 4 = 2 - (1/3)y

Correct answer: A

Rationale: To represent 'Four more than a number, x', we write x + 4. This is equal to '2 less than 1/3 of another number, y', which translates to 1/3y - 2. Therefore, the correct equation is x + 4 = (1/3)y - 2. Choice B is incorrect as it incorrectly combines the values of x and y. Choice C is incorrect as it doesn't properly relate x and y with the given conditions. Choice D is incorrect as it doesn't correctly represent the relationship between x and y according to the given statement.

2. Which of the following nerves has the longest axon in the human body?

• A. Dorsal root ganglion
• B. Laryngeal nerve
• C. Sciatic nerve
• D. None of the above

Correct answer: C

Rationale: The sciatic nerve contains the longest axon in the human body, extending from the lower back down the leg. This nerve is responsible for innervating the muscles of the lower limb. The dorsal root ganglion and laryngeal nerve do not possess axons as long as the sciatic nerve, making them incorrect choices. Therefore, the correct answer is C, the sciatic nerve.

3. In physics, what does the term 'net force' refer to?

• A. Total force acting on an object
• B. Force due to gravity
• C. Force in motion
• D. Force of friction

Correct answer: A

Rationale: In physics, the term 'net force' refers to the total force acting on an object, considering all individual forces acting on it. It is crucial in determining the object's motion and acceleration as it represents the overall force applied to the object. Choice B, 'Force due to gravity,' is incorrect as it refers to a specific force acting on an object due to gravity. Choice C, 'Force in motion,' is incorrect as it does not define the concept of net force. Choice D, 'Force of friction,' is incorrect as it specifically refers to the force opposing motion when two surfaces are in contact.

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. What type of bond links amino acids together to form proteins?

• A. Hydrogen bond
• B. Ionic bond
• C. Disulfide bond
• D. Covalent bond

Correct answer: D

Rationale: Amino acids are linked together by covalent bonds to form proteins. Specifically, the bond that links amino acids together is called a peptide bond, which is a type of covalent bond. The peptide bond forms between the amino group of one amino acid and the carboxyl group of another amino acid, resulting in the formation of a peptide chain. While hydrogen bonds, ionic bonds, and disulfide bonds are important for protein structure and stability, the primary bond responsible for linking amino acids in a protein chain is the covalent peptide bond. Hydrogen bonds are involved in maintaining the secondary structure of proteins, such as alpha helices and beta sheets. Ionic bonds and disulfide bonds contribute to tertiary and quaternary structures of proteins by stabilizing interactions between different parts of the protein or between different protein subunits, respectively.
