1. What is the principle behind the phenomenon of refraction, where waves bend when entering a new medium?

• A. Change in wavelength
• B. Change in frequency
• C. Change in wave speed
• D. None of the above

Correct answer: C

Rationale: Refraction occurs because of the change in wave speed as it enters a new medium, causing the wavefront to bend and change direction.

2. A nurse administers 150mg of medication every 4 hours. How many milligrams will the patient receive in 24 hours?

• A. 300mg
• B. 600mg
• C. 750mg
• D. 900mg

Correct answer: D

Rationale: Rationale: - The patient receives 150mg of medication every 4 hours. - To calculate how many milligrams the patient will receive in 24 hours, we need to determine how many times the medication is administered in 24 hours. - Since the medication is administered every 4 hours, there are 24 hours in a day, so the medication will be administered 24 / 4 = 6 times in 24 hours. - Therefore, the total amount of medication the patient will receive in 24 hours is 150mg x 6 = 900mg.

3. What is the pH value of a neutral solution?

• A. 0
• B. 7
• C. 14
• D. -7

Correct answer:

Rationale: A neutral solution has a pH of 7. The pH scale ranges from 0 to 14, with 7 being neutral.

4. What is the relationship between genetic drift and the founder effect?

• A. Founder effect is a cause of genetic drift within a small population
• B. Genetic drift is a cause of the founder effect in new populations
• C. They are the same phenomenon with different names
• D. They are unrelated concepts.

Correct answer: A

Rationale: Rationale: - The founder effect is a specific type of genetic drift that occurs when a small group of individuals establishes a new population, leading to a loss of genetic variation. - Genetic drift, on the other hand, is a broader concept that refers to random changes in allele frequencies in a population over time due to chance events. - Therefore, the founder effect is a specific scenario within the broader concept of genetic drift, where the establishment of a new population by a small number of individuals leads to genetic changes in the population.

5. Identify the noun clause in the sentence: "My biggest fear is that I wouldn't live life to the fullest."

• A. "My biggest fear"
• B. "that I wouldn't live life to the fullest"
• C. "life"
• D. "the fullest"

Correct answer: B

Rationale: Option B functions as the object of the verb "is," making it a noun clause.

6. The process by which one element changes into another through radioactive decay is known as:

• A. Transmutation
• B. Fission
• C. Fusion
• D. Oxidation

Correct answer: A

Rationale: Transmutation - Radioactive decay alters the atomic structure, changing the element's identity (transmutation).
