1. What is DNA made of?

• A. Proteins
• B. Nucleotides
• C. Lipids
• D. Carbohydrates

Correct answer: B

Rationale: DNA is made up of nucleotides, which are the building blocks of genetic material. Choice A (Proteins) is incorrect because while proteins play a crucial role in the body, they are not the building blocks of DNA. Choice C (Lipids) and Choice D (Carbohydrates) are also incorrect as they are not the primary components of DNA.

2. What is the best description for the term euphoric?

• A. Disease-ridden
• B. High-spirited
• C. Pretentious
• D. Understated

Correct answer: B

Rationale: The term euphoric is best described as high-spirited. Euphoria is a feeling of intense happiness and excitement, so high-spirited accurately conveys the meaning of euphoric. Choices A, C, and D do not capture the essence of euphoria. 'Disease-ridden' has a negative connotation and is unrelated to euphoric. 'Pretentious' means attempting to impress by affecting greater importance, talent, culture, etc., than is actually possessed, which is not synonymous with euphoric. 'Understated' means presented or expressed in a subtle and effective way, which is not the meaning of euphoric.

3. Which type of joint is found in the hip?

• A. Hinge joint
• B. Ball and socket joint
• C. Pivot joint
• D. Saddle joint

Correct answer: B

Rationale: The correct answer is B: Ball and socket joint. The hip joint is classified as a ball and socket joint, allowing for a wide range of movement in multiple directions, including rotation. This joint structure provides stability and mobility, making it ideal for the hip's functions in bearing weight and facilitating various movements. Choice A, Hinge joint, is incorrect as hinge joints allow movement in only one plane, like the elbow or knee. Choice C, Pivot joint, is incorrect as pivot joints allow rotation around a single axis, like the joint between the first and second vertebrae. Choice D, Saddle joint, is incorrect as saddle joints are found in the thumb and allow movement in two planes, but they do not describe the hip joint.

4. What is another word for flux?

• A. Flowing
• B. Restriction
• C. Absorption
• D. Discharge

Correct answer: D

Rationale: Flux is a term used to describe a discharge, which refers to the action of discharging or releasing something. In medical contexts, flux can specifically refer to a discharge of bodily fluids or matter. 'Flowing' (Choice A) is not a synonym of flux; it implies continuous movement rather than discharge. 'Restriction' (Choice B) and 'Absorption' (Choice C) are unrelated to the concept of flux and do not convey the same meaning.

5. What are the 3 types of radiation in nuclear chemistry?

• A. Alpha, Beta, Delta
• B. Alpha, Beta, Gamma
• C. Gamma, Beta, Delta
• D. Delta, Beta, Gamma

Correct answer: B

Rationale: The correct answer is B: Alpha, Beta, Gamma. In nuclear chemistry, the 3 types of radiation are alpha, beta, and gamma radiation. Alpha radiation consists of helium nuclei, beta radiation involves electrons or positrons, and gamma radiation is electromagnetic radiation of high frequency. Choice A is incorrect because 'Delta' is not a type of radiation in nuclear chemistry. Choice C is incorrect as it does not list alpha radiation. Choice D is incorrect as it lists the types in the wrong order and includes 'Delta' instead of alpha radiation.
