Nursing Elites

1. What is the Golgi apparatus?

• A. A network of tubules that transport proteins and lipids throughout the cell
• B. A sac-like structure that stores water and nutrients
• C. The site of protein synthesis
• D. The site of protein modification and packaging

Correct answer: D

Rationale: Rationale: The Golgi apparatus is an organelle in the cell responsible for modifying, sorting, and packaging proteins and lipids for transport to their final destinations. It consists of a series of flattened sacs called cisternae and plays a crucial role in processing proteins synthesized in the endoplasmic reticulum. Option A is incorrect because the network of tubules that transport proteins and lipids throughout the cell is typically associated with the endoplasmic reticulum. Option B is incorrect as the structure described is more characteristic of a vacuole, which stores water and nutrients. Option C is incorrect as protein synthesis primarily occurs in the ribosomes, not the Golgi apparatus.

2. Which of the following is an example of a polymer?

• A. Methane
• B. Ethanol
• C. Polyethylene
• D. Acetic acid

Correct answer: C

Rationale: Polyethylene is a polymer, consisting of a large number of repeating ethylene units. The other choices represent small organic compounds.

3. Which sentence uses strong verbs to create a more vivid image?

• A. The car moved slowly down the street.
• B. The car drove sluggishly down the road.
• C. The car inched down the avenue.
• D. The car traveled down the thoroughfare.

Correct answer: C

Rationale: "Inched" creates a stronger image of the car's slow movement compared to "moved" or "drove."

4. Which of the following is NOT a primary producer in an ecosystem?

• A. Grass
• B. Deer
• C. Algae
• D. Mushroom

Correct answer: B

Rationale: Rationale: - A) Grass: Grass is a primary producer because it can photosynthesize and convert sunlight into energy, making it the base of the food chain. - B) Deer: Deer are consumers that feed on primary producers like grass, so they are not primary producers themselves. - C) Algae: Algae are primary producers that can photosynthesize and produce energy from sunlight. - D) Mushroom: Mushrooms are decomposers that break down organic matter, so they are not primary producers.

5. What are enzymes?

• A. Building blocks of muscle
• B. Biological catalysts
• C. Energy source
• D. Antibodies

Correct answer: B

Rationale: Enzymes are proteins that speed up chemical reactions in our cells. They act like tiny factories, fitting specific molecules (substrates) into their active site to facilitate reactions.

6. 12 is a/an:

• A. even number
• B. odd number
• C. prime number
• D. composite number

Correct answer: A

Rationale: Even numbers are integers divisible by 2 without a remainder. Since 12 divided by 2 equals 6 with no remainder, 12 is even.
