1. Which bones are included in the axial skeleton?

Correct answer: A

Rationale: The correct answer is A: Head, neck, and trunk. The axial skeleton comprises bones located in the head, neck, and trunk region, such as the skull, vertebral column, and rib cage. These bones provide structural support and protect vital organs like the brain, spinal cord, and heart. Choices B and C are incorrect because arms, legs, hands, and feet are part of the appendicular skeleton, not the axial skeleton. The appendicular skeleton is responsible for movement, manipulation, and mobility, while the axial skeleton primarily provides central support and protection for essential organs.

2. Which term describes the ability of a substance to conduct electricity?

Correct answer: C

Rationale: Conductivity is the correct term used to describe the ability of a substance to conduct electricity. Reactivity is the measure of a substance's tendency to undergo chemical reactions. Density refers to the mass per unit volume of a substance, while viscosity is a measure of a fluid's resistance to flow. In the context of conducting electricity, conductivity is the most appropriate term as it directly relates to the substance's electrical conductive properties.

3. Which represents the correct order of airflow in the lungs?

Correct answer: C

Rationale: The correct order of airflow in the lungs starts with air entering through the trachea, moving into the bronchi, then proceeding to the bronchioles, and finally reaching the alveoli where gas exchange occurs. Therefore, the correct sequence is Trachea, Bronchi, Bronchioles, Alveoli, making choice C the accurate representation of the airflow in the lungs. Choices A, B, and D are incorrect because they do not follow the anatomical path of airflow in the lungs as air moves from the trachea to the bronchi, then bronchioles, and finally the alveoli for gas exchange.

4. What is the primary function of the cardiovascular system?

Correct answer: A

Rationale: The primary function of the cardiovascular system is indeed to transport oxygen and nutrients to various tissues in the body. Choice B, 'To regulate blood pressure,' is incorrect as blood pressure regulation is one of the functions of the cardiovascular system but not its primary function. Choice C, 'To digest food,' is incorrect as digestion is primarily a function of the digestive system, not the cardiovascular system. Choice D, 'To filter waste products,' is incorrect as waste product filtration is primarily carried out by the kidneys and liver, not the cardiovascular system.

5. Which of the following represents different types of electromagnetic waves based on their wavelengths and frequencies?

Correct answer: A

Rationale: Electromagnetic waves are categorized based on their wavelengths and frequencies. Visible light, X-rays, radio waves, and gamma rays are all examples of electromagnetic waves with distinct wavelengths and frequencies. The correct answer choice, A, accurately represents different types of electromagnetic waves. Sound waves, water waves, seismic waves, and shock waves are mechanical waves that propagate through a medium via particle interactions, not electromagnetic waves. Longitudinal waves, transverse waves, mechanical waves, and non-mechanical waves are classifications based on the nature of the wave propagation and do not relate to the types of electromagnetic waves which are differentiated by their electromagnetic properties.
