1. The formula for calculating heart rate is HR = (220 - age) * 0.65. If a patient's heart rate is 136.5, what is their age?

• A. 30
• B. 40
• C. 50
• D. 60

Correct answer: B

Rationale: Rearrange the formula to solve for age: age = 220 - (HR / 0.65). Substitute the heart rate (136.5) to get 40 years old.

2. Identify the comprehensive protection for the brain.

• A. Skull
• B. Meninges (Membranes)
• C. Cerebrospinal fluid
• D. All of the above

Correct answer: D

Rationale: Rationale: A) The skull provides a hard, protective covering for the brain, shielding it from external trauma and injury. B) The meninges are three layers of membranes (dura mater, arachnoid mater, and pia mater) that surround the brain and spinal cord, providing additional protection and cushioning. C) Cerebrospinal fluid is a clear, colorless fluid that surrounds the brain and spinal cord, acting as a shock absorber and providing nutrients to the central nervous system. Together, the skull, meninges, and cerebrospinal fluid work in conjunction to provide comprehensive protection for the brain, making option D the correct answer.

3. Identify the noun in the following sentence: The aroma of freshly baked bread filled the kitchen.

• A. filled
• B. kitchen
• C. aroma

4. Which number is the opposite of -3?

• A. -6
• B. 3
• C. 0

• 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.
