1. The process by which one element changes into another through radioactive decay is known as:

• A. Transmutation
• B. Fission
• C. Fusion

Rationale: Transmutation - Radioactive decay alters the atomic structure, changing the element's identity (transmutation).

2. What is the term for a solution with a pH value less than 7?

• A. Acidic
• B. Neutral
• C. Alkaline
• D. Basic

Correct answer: a

Rationale: Solutions with a pH less than 7 are acidic. The other choices do not accurately describe solutions with a pH less than 7.

3. Which of the following is a characteristic of unsaturated fatty acids?

• A. They are solid at room temperature.
• B. They contain only single bonds.
• C. They have a higher melting point.
• D. They contain double or triple bonds.

Correct answer: D

Rationale: Unsaturated fatty acids contain double or triple bonds in their hydrocarbon chains. The other choices do not accurately describe unsaturated fatty acids.

4. What is the term for the shedding of the outermost layer of the epidermis?

• A. Desquamation
• B. Exfoliation
• C. Keratinization
• D. Epidermolysis

Correct answer: A

Rationale: The correct term for the shedding of the outermost layer of the epidermis is desquamation. Desquamation is a natural process where old skin cells are shed off to make way for new cells. Exfoliation refers to the removal of dead skin cells through external means like scrubs. Keratinization is the process by which skin cells produce the protein keratin, while epidermolysis is a condition where the epidermis separates from the dermis. Therefore, in this context, desquamation is the most appropriate term for the shedding of the outermost layer of the epidermis.

5. Ms. Castro learns that some leaders are transactional leaders. Which of the following does

• A. Focuses on management tasks
• B. Is a caretaker
• C. Uses trade-offs to meet goals
• D. Inspires others with vision

Correct answer: C

Rationale: The correct answer is C: 'Uses trade-offs to meet goals.' Transactional leaders focus on the exchange or transaction that occurs between them and their followers. They set clear expectations and goals for their followers and use rewards and punishments to motivate them. This approach involves making trade-offs to achieve desired outcomes, such as rewarding employees for meeting targets or penalizing them for not meeting expectations. Options A and B do not directly relate to transactional leadership, as it is more about goal achievement and motivation through rewards and punishments. Option D describes a transformational leader, who inspires and motivates others through a shared vision and values, which is different from the transactional leadership style described in the question.

• A. 27cm
• B. 32cm
• C. 37cm
• D. 45cm

Correct answer: C

Rationale: Simply add the lengths of all sides: perimeter = side1 + side2 + side3 = 10cm + 12cm + 15cm = 37cm.
