1. As a young manager, she knows that conflict occurs in any organization. Which of the

A. Can be destructive if the level is too high
B. Is not beneficial; hence it should be prevented at all times
C. May result in poor performance
D.

Correct answer: C

Rationale: Conflict in an organization is a natural occurrence that can either be constructive or destructive. Option C is the correct answer because conflict may indeed lead to poor performance if not managed effectively. When conflict is left unresolved or unaddressed, it can create tension, decrease morale, and hinder productivity. By recognizing that conflict can impact performance, the young manager can take proactive steps to address and resolve conflicts in a constructive manner to minimize its negative effects and promote a healthy work environment.

2. How can you predict the charge of an ion formed by an element based on its position on the periodic table?

A. Look for elements with similar atomic weights
B. Identify the group number, which often indicates the typical ionic charge
C. Identify the group number, which often indicates the typical ionic charge
D. Analyze the element's position within the period

Correct answer: B

Rationale: The group number of an element on the periodic table often indicates the typical ionic charge it will form. Elements in the same group tend to have similar chemical properties, including the tendency to gain or lose electrons to achieve a stable electron configuration. This predictable pattern allows us to anticipate the charge of an ion formed by an element based on its position in the periodic table.

3. Negative feedback mechanisms are crucial in the endocrine system to:

A. Increase hormone production continuously
B. Maintain hormone levels within a specific range
C. Cause a constant release of hormones
D. Disrupt communication between glands

Correct answer: B

Rationale: The correct answer is B: 'Maintain hormone levels within a specific range.' Negative feedback mechanisms in the endocrine system are essential for regulating hormone levels. These mechanisms work to counteract any deviations from the set point, ensuring that hormone levels remain balanced and within the optimal range for proper physiological function. Continuous hormone production (A) or constant release of hormones (C) would lead to imbalances and potential harm to the body. Disrupting communication between glands (D) would hinder the coordination necessary for maintaining homeostasis. Therefore, option B is the best choice as it highlights the critical role of negative feedback in keeping hormone levels stable and regulated.

4. What is the term for the chemical reaction that involves the loss of electrons?

A. Reduction
B. Oxidation
C. Neutralization
D. Precipitation

Correct answer: b

Rationale: Oxidation is the chemical reaction that involves the loss of electrons. The other choices describe different types of reactions.

5. Which cartilage type allows for smooth movement at joints and absorbs shock?

A. Hyaline cartilage
B. Fibrocartilage
C. Elastic cartilage
D. None of the above

Correct answer: A

Rationale: The correct answer is A: Hyaline cartilage. Hyaline cartilage is the most abundant type of cartilage in the body and is found in the joints, providing a smooth surface for movement. It also acts as a shock absorber, cushioning the joints during activities. Fibrocartilage is found in intervertebral discs and provides strength and support, but it is not as effective at absorbing shock as hyaline cartilage. Elastic cartilage is found in the external ear and epiglottis, providing flexibility and maintaining shape, but it does not have the same shock-absorbing properties as hyaline cartilage. Therefore, hyaline cartilage is the best choice for a cartilage type that allows for smooth movement at joints and absorbs shock.
