1. Which sentence uses 'etc.' grammatically correct?

• A. The list included diseases such as flu, measles, etc.
• B. The list included flu, measles, etc., and other items.
• C. The list included flu, measles, etc., diseases, and other items.
• D. The list included, flu, etc., measles, diseases, and other items.

Correct answer: A

Rationale: The correct usage of 'etc.' should follow a comma when concluding a list. Option A correctly places 'etc.' at the end of a logical list with a comma before it, following grammatical rules. In option B, a comma should be placed after 'etc.' before introducing 'and other items.' Options C and D either misplace commas or incorrectly use 'etc.' within the list.

2. Which cell organelle functions to transport materials from the endoplasmic reticulum throughout the cell?

• A. Ribosome
• B. Golgi apparatus
• C. Lysosome
• D. Vacuole

Correct answer: B

Rationale: The Golgi apparatus is the correct answer because it functions to transport materials from the endoplasmic reticulum throughout the cell. Ribosomes are responsible for protein synthesis, not transportation of materials. Lysosomes contain enzymes for digestion and waste removal, not for transporting materials. Vacuoles are primarily involved in storage, waste disposal, and maintaining turgor pressure, not in transporting materials from the endoplasmic reticulum.

3. A person consumed 75 grams of protein. This is 30% of the recommended daily intake (RDI) for protein. How many grams of protein does the person need to consume to meet the full RDI?

• A. 250 grams
• B. 225 grams
• C. 260 grams
• D. 300 grams

Correct answer: A

Rationale: To find the full RDI, divide the amount of protein consumed (75 grams) by 30% (or 0.30): 75 ÷ 0.30 = 250 grams. Therefore, the person needs 250 grams of protein to meet the full RDI. Choice A is correct because it accurately calculates the amount needed to reach the full RDI. Choices B, C, and D are incorrect as they do not correctly calculate the total amount of protein needed based on the given information.

4. Which system maintains the body's balance through the release of hormones directly into the bloodstream?

• A. The gastrointestinal system
• B. The endocrine system
• C. The digestive system
• D. The endocrine system

Correct answer: D

Rationale: The correct answer is D: The endocrine system. The endocrine system maintains the body's balance through the release of hormones directly into the bloodstream. Hormones produced by glands in the endocrine system regulate various bodily functions such as metabolism, growth, and reproduction. This system plays a crucial role in maintaining homeostasis by releasing hormones that help control and coordinate different processes in the body. Choices A, C, and B are incorrect. The gastrointestinal system is responsible for digestion, absorption of nutrients, and excretion of waste; the digestive system includes the gastrointestinal system and other accessory organs; and choice B is a duplicate of the correct answer.

5. Ventral refers to which part of the body?

• A. Top
• B. Bottom
• C. Front
• D. Back

Correct answer: C

Rationale: Ventral refers to the front part of the body or an organ. It is the opposite of dorsal, which refers to the back part. So, when describing the direction or location of an anatomical structure, ventral would mean towards the front. Therefore, the correct answer is 'Front.' Choices A, B, and D are incorrect because 'Top' refers to superior, 'Bottom' refers to inferior, and 'Back' refers to dorsal, not ventral.
