1. Which element shares the same group (family) on the periodic table with helium (He)?

Correct answer: A

Rationale: Elements within the same group share similar electron configurations in their outermost shells, resulting in comparable chemical properties. Helium and Neon both belong to Group 18 (Noble Gases), explaining their similarities. Boron, Carbon, and Oxygen are not in the same group as Helium on the periodic table. Boron is in Group 13, Carbon is in Group 14, and Oxygen is in Group 16, which are different from Helium's Group 18.

2. What is the responsibility of the somatic nervous system?

Correct answer: C

Rationale: The somatic nervous system is responsible for controlling voluntary movements of skeletal muscles. This system communicates sensory information and controls voluntary movements, such as walking or reaching for objects. Breathing is primarily regulated by the autonomic nervous system, which functions involuntarily. Thought processes involve complex interactions between various regions of the brain and are not directly controlled by the somatic nervous system. Fear is an emotional response that involves the limbic system of the brain and the autonomic nervous system, not the somatic nervous system.

3. How do efferent fibers exit the spinal cord?

Correct answer: C

Rationale: Efferent fibers, which carry motor commands, exit the spinal cord through the ventral aspect, also known as the anterior aspect. The correct answer is C, 'Through the ventral aspect.' Efferent fibers exiting through the ventral aspect are responsible for carrying motor commands from the spinal cord to the muscles and glands. Choices A, B, and D are incorrect. Efferent fibers do not exit through the dorsal, lateral, or anterior aspects of the spinal cord.

4. How will 0.80 be written as a percent?

Correct answer: D

Rationale: To convert a decimal to a percent, you multiply by 100. Therefore, 0.80 * 100 = 80%. The correct answer is D. Choice A (40%) is incorrect as 0.80 is not equivalent to 40%. Choice B (125%) is incorrect as it is greater than 100%. Choice C (90%) is incorrect as it does not reflect the correct conversion of 0.80 to a percent.

5. What is the difference between heat and temperature?

Correct answer: B

Rationale: Heat and temperature are distinct concepts. Heat is a form of energy that transfers from a higher temperature object to a lower temperature object, while temperature represents the average kinetic energy of particles in a substance. Heat is quantified in units like Joules or calories, whereas temperature is typically gauged in degrees Celsius or Fahrenheit. Therefore, choice B correctly distinguishes between heat and temperature, making it the correct answer. Choices A, C, and D are incorrect because they do not accurately define the difference between heat and temperature. Choice A erroneously suggests they are the same, choice C confuses the direction of heat and temperature flow, and choice D provides inaccurate units for measuring heat and temperature.
