1. Which law of motion explains the behavior of rockets in space?

• A. Newton's First Law
• B. Newton's Second Law
• C. Newton's Third Law
• D. None of the above

Correct answer: c

Rationale: Newton's Third Law of motion explains that for every action, there is an equal and opposite reaction, which propels rockets in space.

2. Which of the following sentences uses figurative language?

• A. The scientist conducted an experiment.
• B. The child ran like a cheetah.
• C. The book contained many pages.
• D. The teacher explained the concept clearly.

Correct answer: B

Rationale: This sentence uses a simile, comparing the child's speed to a cheetah's.

3. 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.

4. What is the difference between a phylum and a class?

• A. Phylums are broader and more general
• B. Classes are broader and more general
• C. They are synonyms, used for the same groups
• D. Phylums are for plants, classes are for animals

Correct answer: A

Rationale: Rationale: In biological classification, a phylum is a higher taxonomic rank than a class. Phylum is a broader category that includes multiple classes within it. Phylum represents a group of organisms sharing a common body plan or evolutionary history, while a class is a more specific category within a phylum that includes organisms with similar characteristics. Therefore, phylums are broader and more general compared to classes.

5. Which type of symbiosis is where both organisms benefit from the interaction?

• A. Mutualism
• B. Commensalism
• C. Parasitism
• D. Predation

Correct answer: A

Rationale: Rationale: Mutualism is a type of symbiosis in which both organisms involved benefit from the interaction. This relationship is characterized by cooperation and mutual support, leading to advantages for both parties. In mutualistic relationships, each organism provides something that the other needs, resulting in a mutually beneficial outcome. Examples of mutualism include the relationship between bees and flowers (pollination) and the partnership between nitrogen-fixing bacteria and leguminous plants.

6. A patient's weight is measured as 75 kilograms. What is their weight in pounds?

• A. 132 pounds
• B. 150 pounds
• C. 110 pounds
• D. 85 pounds

Correct answer: B

Rationale: Rationale: To convert kilograms to pounds, you can use the conversion factor 1 kilogram is approximately equal to 2.20462 pounds. Therefore, to convert 75 kilograms to pounds: 75 kilograms * 2.20462 pounds/kilogram ≈ 165.3475 pounds Rounded to the nearest whole number, the patient's weight of 75 kilograms is approximately 165 pounds. Among the given options, the closest weight in pounds to 165 is 150 pounds (option B).
