Biology

1. Identify the comprehensive protection for the brain.

Correct answer: D

Rationale: Rationale: A) The skull provides a hard, protective covering for the brain, shielding it from external trauma and injury. B) The meninges are three layers of membranes (dura mater, arachnoid mater, and pia mater) that surround the brain and spinal cord, providing additional protection and cushioning. C) Cerebrospinal fluid is a clear, colorless fluid that surrounds the brain and spinal cord, acting as a shock absorber and providing nutrients to the central nervous system. Together, the skull, meninges, and cerebrospinal fluid work in conjunction to provide comprehensive protection for the brain, making option D the correct answer.

2. What is the relationship between the frequency and wavelength of a wave?

Correct answer: a

Rationale: Frequency and wavelength have an inverse relationship - as one increases, the other decreases.

3. What type of energy does a stretched rubber band possess?

Correct answer:

Rationale: When a rubber band is stretched, it stores potential energy due to its position or state.

4. What property of matter refers to the amount of space occupied by an object?

Correct answer: b

Rationale: Volume measures the amount of space occupied by an object.

5. Which of the following factors does NOT affect the rate of dissolution of a solute in a solvent?

Correct answer: B

Rationale: Pressure does not affect the rate of dissolution of a solute in a solvent. The factors that do affect the rate of dissolution include temperature, surface area, and particle size. Temperature generally increases the rate of dissolution as it provides more energy for the solute particles to break apart and mix with the solvent. Increasing the surface area of the solute by grinding it into smaller particles or increasing its contact area with the solvent can also speed up dissolution. Similarly, reducing the particle size of the solute can increase the rate of dissolution by providing more surface area for interaction with the solvent.

6. A light ray travels from air (refractive index 1.00) into water (refractive index 1.33). What happens to its speed and direction?

Correct answer: A

Rationale: Due to the change in refractive index, the light ray bends towards the normal (water) as it slows down upon entering the denser medium.
