1. Which term refers to a position farther from the midline of the body? For example, the little toe is lateral to the big toe on the same foot.

• A. Lateral
• B. Medial
• C. Proximal
• D. Distal

Correct answer: A

Rationale: The correct answer is A: Lateral. Lateral refers to a position farther away from the midline of the body. In the example provided, the little toe is indeed lateral to the big toe on the same foot. This is in contrast to 'medial,' which means closer to the midline. 'Proximal' refers to a position closer to the point of attachment or the trunk of the body, while 'distal' refers to a position farther from the point of attachment or the trunk of the body.

2. What is the name for the flexible connection between bones at the wrist or ankle?

• A. Ligament
• B. Tendon
• C. Fascia
• D. Synovial joint

Correct answer: A

Rationale: The correct answer is A: Ligament. Ligaments are tough bands of tissue that connect bones to other bones at joints, providing stability and support. In the case of the wrist or ankle, ligaments play a crucial role in maintaining the structural integrity and allowing for proper movement of these joints. Tendons (option B) connect muscles to bones, not bones to bones. Fascia (option C) is a connective tissue that surrounds muscles and other structures, not connecting bones at joints. A synovial joint (option D) is a type of joint that allows for movement between bones, but it is not the flexible connection between bones at the wrist or ankle.

3. Which of the following is NOT a risk factor for developing atherosclerosis?

• A. High blood pressure
• B. High levels of LDL cholesterol
• C. Regular physical activity
• D. Smoking

Correct answer: C

Rationale: Regular physical activity is not a risk factor for developing atherosclerosis; in fact, it is associated with a reduced risk. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. Regular physical activity plays a crucial role in improving cardiovascular health, reducing the risk of atherosclerosis, and maintaining overall well-being. Therefore, the correct answer is regular physical activity (choice C).

4. What is the building block of DNA?

• A. Amino acid
• B. Nucleotide
• C. Phosphate group
• D. Fatty acid

Correct answer: B

Rationale: - Amino acids are the building blocks of proteins, not DNA. - Nucleotide is the correct building block of DNA. A nucleotide consists of a sugar (deoxyribose in DNA), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). - The option 'C) Phosphate group' is incorrect as it is only part of a nucleotide, not the complete building block of DNA. - Fatty acids are not the building blocks of DNA; they are a type of lipid molecule.

5. What is the relationship between the frequency and period of a wave?

• A. They are unrelated
• B. Frequency = Period
• C. Frequency = 1/Period
• D. Period = 1/Frequency

Correct answer: D

Rationale: The correct relationship between frequency and period of a wave is that Period = 1/Frequency. This relationship indicates that the period of a wave is the reciprocal of its frequency. Frequency refers to the number of complete cycles of a wave occurring in a unit of time, while the period is the time taken for one complete cycle of the wave to occur. As frequency and period are inversely related, the correct formula to express this relationship is Period = 1/Frequency. Choice A is incorrect as frequency and period are related. Choice B is incorrect as frequency and period are not equal. Choice C is incorrect as it suggests that frequency is directly proportional to period, which is not the case.
