Chemistry

1. 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.

2. What type of figurative language is used in the statement "Her laughter was music to my ears"?

Correct answer: A

Rationale: The statement directly compares laughter to music, forming a metaphor.

3. She knows that there are external forces that influence changes in his unit. Which of the

Correct answer: A

Rationale: The correct answer is option A: 'Memo from the CEO to cut down on electrical consumption.' This choice represents an external force that can influence changes in the unit by setting a directive from top management to reduce electricity usage, impacting operations and decisions within the unit. While options B, C, and D may also affect the unit to some extent, they are not as directly tied to external influences as the CEO's memo. The demands of the labor sector (option B) and low staff morale (option C) are internal factors, while regulatory and accreditation standards (option D) are more overarching guidelines rather than specific external forces impacting the unit. Therefore, the most direct and relevant external force in this scenario is the directive from the CEO, making option A the correct choice.

4. What phenomenon occurs when light passes through a medium but does not change direction, such as when passing through a window?

Correct answer: d

Rationale: Transmission occurs when light passes through a medium without changing direction, as observed when light passes through a window.

5. Which hormone is responsible for stimulating the development of sex organs and secondary sex characteristics during puberty?

Correct answer: B

Rationale: The correct answer is B: Testosterone (in males) and Estrogen (in females). During puberty, the release of these sex hormones plays a crucial role in the development of sex organs and secondary sex characteristics. Testosterone is responsible for male characteristics like facial hair, deepening of the voice, and muscle growth, while Estrogen contributes to female features such as breast development and the widening of hips. Growth hormone primarily regulates overall growth and development, while Insulin is involved in glucose metabolism and Thyroid hormone controls metabolism and energy levels. Therefore, the correct choice is B as Testosterone and Estrogen are specifically responsible for the changes seen during puberty.

6. Vacuoles are large sacs for storage in plant cells. What is their main function in animal cells?

Correct answer: B

Rationale: Vacuoles in plant cells are primarily used for storage of water, nutrients, and waste products. In animal cells, vacuoles are smaller and serve various functions, including waste storage and disposal. Option B, 'Waste storage and disposal,' is the correct answer because vacuoles in animal cells help maintain cellular homeostasis by storing and breaking down waste materials. This process aids in detoxification and maintaining proper cellular function in animal cells, similar to the role of vacuoles in plant cells.
