1. How many centimeters are in one meter?

• A. 1/10 cm
• B. 100 cm
• C. 10 cm
• D. 1000 cm

Correct answer: B

Rationale: The correct answer is B: 100 cm. One meter is equivalent to 100 centimeters. This conversion is based on the metric system, where the prefix 'centi-' represents one hundredth. Choices A, C, and D are incorrect because they do not accurately reflect the conversion of meters to centimeters. Choice A, '1/10 cm,' is incorrect as it represents a fraction of a centimeter, not the full conversion from meters to centimeters. Choice C, '10 cm,' is incorrect as it represents the conversion from decimeters to centimeters, not meters to centimeters. Choice D, '1000 cm,' is incorrect as it represents the conversion from meters to millimeters, not centimeters.

2. Which of the following is not a type of muscle tissue?

• A. Skeletal
• B. Smooth
• C. Cardiac
• D. Adipose

Correct answer: D

Rationale: The correct answer is D, Adipose. Adipose tissue is a type of connective tissue that stores fat, not muscle tissue. Skeletal, smooth, and cardiac are all types of muscle tissues found in the body. Skeletal muscle tissue is responsible for voluntary movements and is attached to bones. Smooth muscle tissue is found in the walls of hollow organs and blood vessels, responsible for involuntary movements. Cardiac muscle tissue is found in the heart and is responsible for pumping blood throughout the body. Adipose tissue, on the other hand, primarily functions as a storage site for energy in the form of fat.

3. Which of the following touch receptors respond to light touch and slower vibrations?

• A. Merkel's discs
• B. Pacinian corpuscles
• C. Meissner's corpuscles
• D. Ruffini endings

Correct answer: A

Rationale: The correct answer is A, Merkel's discs. Merkel's discs are touch receptors that respond to light touch and slower vibrations, making them ideal for detecting subtle tactile stimuli. Pacinian corpuscles are specialized in detecting deep pressure and high-frequency vibrations, not light touch or slower vibrations. Meissner's corpuscles, on the other hand, are sensitive to light touch and low-frequency vibrations, but they do not specifically respond to slower vibrations. Ruffini endings are responsible for detecting skin stretch and continuous touch pressure, differentiating them from Merkel's discs, which are specifically attuned to light touch and slower vibrations.

4. A car travels 60 miles in 1 hour. How long will it take to travel 180 miles at the same speed?

• A. 3 hours
• B. 4 hours
• C. 2.5 hours
• D. 5 hours

Correct answer: A

Rationale: To find the time needed to travel 180 miles at the same speed of 60 miles per hour, you divide the total distance by the speed. 180 miles ÷ 60 mph = 3 hours. Therefore, it will take 3 hours to travel 180 miles at the given speed. Choice B, 4 hours, is incorrect as it does not align with the calculation. Choice C, 2.5 hours, is incorrect as it underestimates the time needed for the distance. Choice D, 5 hours, is incorrect as it overestimates the time required based on the given speed.

5. Which of the following organs is responsible for producing digestive enzymes?

• A. Liver
• B. Pancreas
• C. Gallbladder
• D. Esophagus

Correct answer: B

Rationale: The correct answer is the Pancreas. The pancreas is an organ that produces digestive enzymes to aid in the breakdown of food in the small intestine. These enzymes play a crucial role in the digestion and absorption of nutrients from the food we eat. The liver is responsible for producing bile, not digestive enzymes. The gallbladder stores and concentrates bile produced by the liver, which aids in the digestion of fats. The esophagus is a muscular tube that helps in the movement of food from the mouth to the stomach and does not produce digestive enzymes.
