1. Which fibrous connective tissue attaches muscles to bones?

• A. Tendons
• B. Ligaments
• C. Cartilage
• D. Fascia

Correct answer: A

Rationale: Tendons are fibrous connective tissues that attach muscles to bones, allowing the transmission of forces generated by muscles and facilitating movement at joints. Ligaments, on the other hand, connect bones to other bones, providing stability. Cartilage is a firm, flexible connective tissue found in joints and the respiratory tract. Fascia surrounds muscles, groups of muscles, blood vessels, and nerves, offering support and protection. Therefore, the correct answer is tendons as they specifically connect muscles to bones.

2. What does exogenous mean?

• A. Produced within the body
• B. Produced outside the body
• C. A byproduct
• D. Caused by bacteria

Correct answer: B

Rationale: Exogenous means produced outside the body. In this context, 'within the body' (Choice A), 'a byproduct' (Choice C), and 'caused by bacteria' (Choice D) do not accurately define exogenous. The correct definition of exogenous specifically refers to something originating or produced externally.

3. A doctor prescribes 150 milligrams of medication to be taken orally every 12 hours. How many grams should the patient take per dose?

• A. 0.015 grams
• B. 0.15 grams
• C. 1.5 grams
• D. 15 grams

Correct answer: B

Rationale: Rationale: 1. Convert milligrams to grams: 150 milligrams = 150/1000 = 0.15 grams. Therefore, the patient should take 0.15 grams per dose. Choice A (0.015 grams) is incorrect as the decimal point was misplaced, leading to a value that is too small. Choice C (1.5 grams) is incorrect as it represents 10 times the correct value. Choice D (15 grams) is incorrect as it represents 100 times the correct value. The correct conversion from milligrams to grams is 0.15 grams.

4. What is the cost of building a fence around a square lawn with an area of 62,500 square meters at a rate of $5 per meter?

• A. $4,000
• B. $4,500
• C. $5,000
• D. $5,500

Correct answer: C

Rationale: To determine the cost of building a fence around the square lawn, first calculate the length of one side by finding the square root of the area: √62500 = 250 meters (length of one side). The perimeter of a square is four times the length of one side, so the perimeter of the lawn is 4 * 250 = 1000 meters. To find the cost of the fence, multiply the perimeter by the cost per meter: 1000 meters * $5/meter = $5000. Therefore, the correct answer is $5,000, which corresponds to choice C. Choice A ($4,000), choice B ($4,500), and choice D ($5,500) are incorrect as they do not accurately calculate the cost based on the given information.

5. An incandescent lamp consumes 60 Joules of energy per second. What is the power rating of this lamp?

• A. 1 Watt (W)
• B. 60 Watts (W)
• C. 1/60 Joules
• D. Impossible to determine without knowing the voltage

Correct answer: B

Rationale: Power is defined as energy consumed per unit time. If the lamp consumes 60 Joules of energy per second, the power rating is 60 Watts. Therefore, choice B is correct. Choice A ('1 Watt') is incorrect because the lamp consumes 60 Joules per second, not 1 Joule per second. Choice C ('1/60 Joules') is incorrect as it does not represent the power rating. Choice D ('Impossible to determine without knowing the voltage') is incorrect because power can be calculated using energy consumption per unit time without needing to know the voltage.
