1. What does the term "solute" refer to in a solution?

• A. The substance present in the largest amount
• B. The substance that dissolves in the solvent
• C. The liquid portion of the solution
• D. The temperature at which the solution freezes

Correct answer: B

Rationale: The solute is the substance that dissolves in the solvent to form a solution. The other choices do not accurately describe the solute.

2. Which of the following phases of the cell cycle is characterized by the replication of DNA?

• A. Interphase
• B. Mitosis
• C. Meiosis
• D. Cytokinesis

Correct answer: A

Rationale: Rationale: Interphase is the phase of the cell cycle where the cell spends the majority of its time and is characterized by three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). During the S phase of interphase, DNA replication occurs, leading to the duplication of the genetic material in the cell. This ensures that each daughter cell produced during cell division receives a complete set of genetic information. Mitosis is the phase of the cell cycle where the replicated DNA is divided equally between two daughter cells, while meiosis is a specialized type of cell division that occurs in sexually reproducing organisms to produce gametes. Cytokinesis is the final stage of the cell cycle where the cytoplasm divides, resulting in two separate daughter cells.

3. What is the scientific term for the study of genes and their role in disease?

• A. Molecular biology
• B. Biochemistry
• C. Evolutionary biology
• D. Genomic medicine

Correct answer: D

Rationale: Rationale: A) Molecular biology primarily focuses on the study of biological processes at a molecular level, including the structure and function of molecules essential to life such as DNA, RNA, and proteins. While molecular biology may involve the study of genes, it is not specifically focused on their role in disease. B) Biochemistry is the branch of science that explores the chemical processes and substances that occur within living organisms. While biochemistry may involve the study of genetic material, it does not specifically focus on the role of genes in disease. C) Evolutionary biology is the study of the processes that have shaped the diversity of life on Earth over time, including how species evolve and adapt to their environments. While genetics plays a role in evolutionary biology, it is not the primary focus of this field. D) Genomic medicine is the scientific term for the study of genes and their role in disease. This field involves understanding how variations in an indi

4. The phrase "green alternative" suggests that bioremediation is...

• A. The most economical option for plastic cleanup.
• B. Faster and more efficient than traditional methods.
• C. Environmentally friendly and less harmful than other solutions.
• D. More aesthetically pleasing than existing approaches.

Correct answer: C

Rationale: The passage contrasts bioremediation with "traditional methods," explicitly linking it to being environmentally friendly.

5. What does "monophyletic" mean in the context of classification?

• A. A group with a single representative organism
• B. A group with diverse and unrelated members
• C. A group with similar functions but different origins
• D. A group descended from a common ancestor

Correct answer: D

Rationale: Rationale: In the context of classification, "monophyletic" refers to a group that includes a common ancestor and all of its descendants. This group shares a single evolutionary origin and forms a complete branch on a phylogenetic tree. Monophyletic groups are considered natural and valid taxonomic units because they reflect evolutionary relationships accurately. Option D is the correct choice as it accurately defines the term "monophyletic" in the context of classification.

6. Identify the pronoun in the following sentence: She quickly finished her homework before dinner.

• A. quickly
• B. finished
• C. her
• D. before

Correct answer: C

Rationale: Pronouns take the place of nouns. "Her" replaces a specific female person's name.
