English Grammar

1. Which word is spelled correctly?

Correct answer: B

Rationale: Option B is the correct spelling for "to submit or agree without protest."

2. Which verb tense best fits the blank: "By next month, she _____ the project for a year."

Correct answer: C

Rationale: The sentence emphasizes the completed duration of the project by next month, requiring the present perfect continuous tense.

3. Which of the following numbers is a perfect square?

Correct answer: D

Rationale: A perfect square is a number obtained by squaring an integer. 16 is the result of squaring 4 (4 x 4 = 16). The other answer choices are not the product of squaring any whole number.

4. What property of a substance refers to its ability to be drawn into thin wires without breaking?

Correct answer: c

Rationale: Ductility is the property that describes a substance's ability to be drawn into thin wires without breaking.

5. What is the term for the process of separating the components of a solution based on their different rates of movement through a medium?

Correct answer: c

Rationale: Chromatography is a technique used to separate the components of a solution based on their different rates of movement through a medium. The other choices are different separation techniques.

6. Molecular clocks utilize the accumulation of mutations in DNA sequences to estimate the evolutionary divergence time between species. This method relies on the assumption that:

Correct answer: A

Rationale: Rationale: A molecular clock is a method used to estimate the time of divergence between species by measuring the accumulation of mutations in DNA sequences. This method relies on the assumption that mutations occur at a relatively constant rate over time. If the rate of mutation were not constant, it would be challenging to accurately estimate the evolutionary divergence time between species. Therefore, option A is the most appropriate choice as it aligns with the fundamental principle underlying the molecular clock hypothesis. Option B is incorrect because the assumption that species with more morphological similarities diverged more recently does not directly relate to the concept of molecular clocks and the accumulation of mutations in DNA sequences. Option C is incorrect because mutations are not always beneficial and do not always contribute to increased fitness. Mutations can be neutral or deleterious as well, and their accumulation is what is used to estimate evolutionary di
