Anatomy
1. Frequent, painful urination is a common symptom of:
- A. Diabetes
- B. Urinary tract infection (UTI)
- C. Kidney stones
- D. All of the above
Correct answer: D
Rationale: The correct answer is D, 'All of the above.' Frequent, painful urination can be a symptom of various conditions affecting the urinary system. In diabetes, high blood sugar levels can lead to increased urine production. UTIs often cause painful urination due to the infection in the urinary tract. Kidney stones can also result in frequent and painful urination as they obstruct the flow of urine. Therefore, all three options can present with the common symptom of frequent, painful urination, making 'All of the above' the correct choice.
2. What is the relationship between the frequency and wavelength of a wave?
- A. Inversely proportional
- B. Directly proportional
- C. No relationship
- D. Depend on the medium
Correct answer: a
Rationale: Frequency and wavelength have an inverse relationship - as one increases, the other decreases.
3. According to Newton's third law of motion, if you push against a wall with a certain force, the wall will push back with:
- A. A smaller force
- B. An equal force
- C. A greater force
- D. No force at all
Correct answer: b
Rationale: Newton's third law states that for every action, there is an equal and opposite reaction.
4. A table shows the blood pressure readings for different age groups. How do you determine the patient with the highest systolic pressure?
- A. Find the largest number in the "systolic pressure" column.
- B. Compare the means (averages) of each age group.
- C. Add all systolic pressure values and divide by the total number of patients.
- D. Subtract the lowest systolic pressure from the highest.
Correct answer: A
Rationale: The best way is to compare the average systolic pressure values for each age group to identify the highest.
5. You need to repaint a cylindrical water tank with a diameter of 2 meters and a height of 3 meters. Assuming one can of paint covers 10 sq m, how many cans do you need (consider only the exterior surface)?
- A. 6 cans
- B. 9 cans
- C. 12 cans
- D. 15 cans
Correct answer: C
Rationale: Calculate the surface area of the cylinder and divide by the coverage area per can.
6. What enzyme plays a crucial role in DNA replication during the S phase of interphase?
- A. Helicase
- B. DNA polymerase
- C. Ligase
- D. Topoisomerase
Correct answer: B
Rationale: Rationale: During the S phase of interphase, DNA replication occurs. DNA polymerase is the enzyme responsible for synthesizing new DNA strands by adding nucleotides in a complementary fashion to the template strand. It plays a crucial role in replicating the entire genome accurately. Helicase unwinds the double-stranded DNA, topoisomerase relieves the tension in the DNA strands, and ligase joins the Okazaki fragments on the lagging strand. However, DNA polymerase is the enzyme directly involved in the synthesis of new DNA strands during replication.
