1. Which type of muscle is responsible for moving the skeleton?

Correct answer: B

Rationale: Skeletal muscle is the correct answer as it is responsible for moving the skeleton. Skeletal muscles are under voluntary control, meaning they can be consciously controlled by the individual. Cardiac muscle (Choice A) is found in the heart and is responsible for pumping blood, not moving the skeleton. Smooth muscle (Choice C) is found in internal organs and is responsible for involuntary movements like digestion. Voluntary muscle (Choice D) is not a specific type of muscle; it refers to muscles that can be consciously controlled, which includes skeletal muscles.

2. What is a benefit of a taxonomic system?

Correct answer: D

Rationale: The correct answer is D. A taxonomic system allows scientists to classify living organisms based on their molecular and genetic traits. This classification helps in understanding the relationships and evolutionary history of different organisms, providing insights into their characteristics and behaviors. Choices A, B, and C do not directly relate to the primary purpose and benefit of a taxonomic system, which is the systematic classification of organisms.

3. Which of the following is a common property of both acids and bases?

Correct answer: D

Rationale: The correct answer is D. Both acids and bases can conduct electricity when dissolved in water. Acids ionize in water to produce H+ ions, which can carry an electric current, while bases ionize to produce OH- ions, which also conduct electricity. The other options are not common properties of both acids and bases. Reacting with metals to produce hydrogen gas is characteristic of acids, tasting sour is a property of acids, and turning blue litmus paper red is a property of bases, not a common property shared by both.

4. What is the primary function of Bartholin's glands?

Correct answer: B

Rationale: Bartholin's glands are two small glands located on each side of the vaginal opening. Their primary function is to secrete fluids that help lubricate the vagina during sexual arousal. This lubrication helps to reduce friction and discomfort during sexual activity, making intercourse more comfortable and pleasurable. Choices A, C, and D are incorrect because Bartholin's glands do not secrete hormones to respond to stress, control growth and development, or stimulate the development of T cells. Their main role is specifically related to vaginal lubrication.

5. What is the pH of a solution with a hydrogen ion concentration of (1x10^{-9}) M?

Correct answer: C

Rationale: The pH of a solution can be calculated using the formula: pH = -log[H+]. Given that the hydrogen ion concentration is \(1 \times 10^{-9}\) M, the pH can be calculated as pH = -log(1 x 10^-9) = 9. Therefore, the correct answer is C) 9.
