1. Which of the following describes the difference between prokaryotic and eukaryotic cells?

• A. Prokaryotic cells have a nucleus, while eukaryotic cells don't.
• B. Eukaryotic cells are simpler in structure than prokaryotic cells.
• C. Prokaryotic cells have membrane-bound organelles, while eukaryotic cells don't.
• D. Eukaryotic cells have a true nucleus and membrane-bound organelles, while prokaryotic cells lack these.

Correct answer: D

Rationale: Eukaryotic cells have a true nucleus that contains the genetic material, while prokaryotic cells lack a true nucleus. Eukaryotic cells also have membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus, which are absent in prokaryotic cells.

2. Which of the following is a correctly punctuated compound sentence?

• A. The moonlight glowed white on the roof next door, and the sky was a gentle summer blue.
• B. The raspberries we just picked from the garden are ripe and sweet.
• C. She spent all afternoon studying for the biology test, but she neglected to work on her psychology paper.
• D. The man often drew sketches in his room, but he never liked to show his art to anyone.

Correct answer: A

Rationale: Choice A is the correct answer as it presents a correctly punctuated compound sentence. It consists of two independent clauses separated by a comma and the coordinating conjunction 'and.' This punctuation accurately connects the two related ideas. Choice B is incorrect because it lacks a comma before the coordinating conjunction 'and,' making it a run-on sentence. Choice C is incorrect due to the use of a semicolon before the coordinating conjunction 'but,' which is unnecessary in this context. Choice D is incorrect as it lacks a comma before the coordinating conjunction 'but,' resulting in a comma splice error.

3. What is the formula for calculating the volume of a solid object?

• A. V = W/L
• B. V = L x W x H
• C. V = W/H
• D. V = L/W

Correct answer: B

Rationale: The correct formula for calculating the volume of a solid object is V = L x W x H, where L represents the length, W represents the width, and H represents the height. Choice A (V = W/L) is incorrect as it represents a division operation, not multiplication. Choice C (V = W/H) is incorrect as it does not account for the width and height. Choice D (V = L/W) is incorrect as it represents the inverse operation of what is needed to calculate volume.

4. What are Mendel's laws?

• A. Law of inheritance, law of expression
• B. Law of segregation, law of independent assortment
• C. Law of dominance, law of recessiveness
• D. Law of mutation, law of crossing over

Correct answer: B

Rationale: The correct answer is B. Mendel's laws consist of the law of segregation, which states that each parent passes one allele for each trait, and the law of independent assortment, which explains that genes for different traits are inherited independently. Choice A is incorrect because 'law of expression' is not one of Mendel's laws. Choice C is incorrect because 'law of dominance' and 'law of recessiveness' do not represent the two main laws proposed by Mendel. Choice D is incorrect because 'law of mutation' and 'law of crossing over' are not part of Mendel's original laws.

5. Which of the following sentences is punctuated correctly?

• A. A carpenter must use certain tools - hammers, saws, chisels - to finish a job.
• B. A carpenter must use certain tools: hammers, saws, chisels to finish a job.
• C. A carpenter must use certain tools hammers, saws, chisels to finish a job.
• D. A carpenter must use certain tools; hammers, saws, chisels to finish a job.

Correct answer: A

Rationale: Choice A is the correct answer as the sentence is correctly punctuated using em dashes to set off the list. The em dashes help to clearly separate the list of tools from the rest of the sentence. In Choice B, a colon is used, which is incorrect as colons are typically used to introduce a list, not within the list itself. Choice C lacks any punctuation to separate the list, making it unclear and incorrect. Choice D uses semicolons, which are not appropriate for separating items in a list, making it incorrect as well.
