1. What skin condition is characterized by red, itchy, and inflamed patches?

A. Eczema
B. Psoriasis
C. Melanoma
D. Keloid

Correct answer: A

Rationale: The correct answer is A: Eczema. Eczema is a common skin condition that is characterized by red, itchy, and inflamed patches on the skin. It is often triggered by environmental factors or allergies and can vary in severity. Psoriasis (option B) is also a skin condition that causes red, scaly patches on the skin, but it is typically thicker and more silver or white in color compared to eczema. Melanoma (option C) is a type of skin cancer that usually presents as a new mole or a changing mole on the skin, rather than red, itchy patches. Keloid (option D) is a raised scar that can result from an overgrowth of scar tissue. Therefore, the most appropriate answer to this question is A: Eczema, based on the description of red, itchy, and inflamed patches.

2. A large geographic area characterized by similar climate, plants, and animals is called a:

A. Population
B. Community
C. Biome
D. Ecosystem

Correct answer: C

Rationale: Rationale: A) Population refers to a group of individuals of the same species living in a specific area. B) Community refers to all the populations of different species living and interacting in a particular area. C) Biome is a large geographic area characterized by similar climate, plants, and animals. Biomes are defined by factors such as temperature, precipitation, and vegetation types. D) Ecosystem refers to a community of living organisms interacting with each other and their physical environment. An ecosystem can be part of a biome.

3. 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.

4. Which of the following is a balanced chemical equation?

A. H2 + O2 â†’ H2O
B. 2H2 + O2 â†’ 2H2O
C. 3H2O â†’ 2H2 + O2
D. H2O â†’ H2 + O2

Correct answer: b

Rationale: The equation is balanced, with equal numbers of atoms of each element on both sides.

5. Which of the following terms refers to the degeneration of nerve tissue?

A. Potentiation
B. Demyelination
C. Reuptake
D. Neurogenesis

Correct answer: B

Rationale: The correct answer is B: 'Demyelination.' Demyelination is the term used to describe the degeneration of the myelin sheath, the protective covering of nerve fibers. This process can lead to impaired nerve signal transmission and potential nerve damage. 'Potentiation' refers to the strengthening of neural connections, 'Reuptake' is the reabsorption of neurotransmitters by the presynaptic neuron, and 'Neurogenesis' is the generation of new nerve cells. In this context, demyelination is the most appropriate term related to nerve tissue degeneration.
