1. Which of the following is NOT a common symptom of pregnancy?

• A. Fatigue
• B. Nausea
• C. Increased urination
• D. Loss of appetite

Correct answer: D

Rationale: The correct answer is D: "Loss of appetite." While it is common for pregnant individuals to experience fatigue, nausea, and increased urination due to hormonal changes and the body's adaptations during pregnancy, a loss of appetite is not typically a common symptom. Most pregnant individuals experience increased appetite, particularly in the early stages of pregnancy. This increased appetite is often attributed to the body's need for additional nutrients to support the growing fetus. Therefore, the absence of appetite loss makes option D the correct choice in this question.

2. What is the main reason why elements in Group 18 (Noble gases) are generally unreactive?

• A. They have high atomic masses
• B. They lack valence electrons
• C. Their outermost electron shells are completely filled
• D. They exist as single atoms, not molecules

Correct answer: C

Rationale: Noble gases have their outermost electron shells filled with 8 electrons, achieving a stable configuration with minimal urge to gain or lose electrons, making them less prone to chemical reactions.

3. The term "symbiotic relationship" describes an interaction between two organisms where:

• A. One organism benefits and the other is unaffected
• B. Both organisms are harmed by the interaction
• C. One organism benefits and the other is negatively impacted
• D. Both organisms benefit from the interaction

Correct answer: D

Rationale: Rationale: In a symbiotic relationship, both organisms involved benefit from the interaction. This mutually beneficial relationship can take different forms, such as mutualism where both organisms benefit, commensalism where one organism benefits and the other is unaffected, or parasitism where one organism benefits at the expense of the other. In this case, the term "symbiotic relationship" specifically refers to a scenario where both organisms derive some form of benefit from their interaction.

4. Which sentence uses the semicolon correctly?

• A. The play was long; however, it was very entertaining.
• B. The guests arrived; Sarah greeted them at the door.
• C. John likes apples; Mary prefers oranges.
• D. He was tired; he went to bed early.

Correct answer: B

Rationale: Option B joins two independent clauses related to the same event.

5. Choose the correct pronoun to complete the sentence: "Neither Michael nor Sarah ____ their homework finished yet."

• A. has
• B. have
• C. are having
• D. does have

Correct answer: B

Rationale: When referring to "neither" followed by two subjects, the verb agrees with the plural subject ("Sarah"). So, "have" is the correct answer.

6. The process by which an organism adapts to its environment through inherited traits is known as

• A. Acclimatization
• B. Behavioral ecology
• C. Natural selection
• D. Niche partitioning

Correct answer: C

Rationale: Rationale: A) Acclimatization refers to the short-term physiological adjustments an individual organism makes in response to changes in its environment. This process is reversible and does not involve inherited traits. B) Behavioral ecology is the study of how behavior contributes to an organism's survival and reproduction in its environment. While behavior can be influenced by natural selection, it is not the process by which an organism adapts through inherited traits. C) Natural selection is the process by which organisms with advantageous traits for their environment are more likely to survive, reproduce, and pass on those traits to their offspring. Over time, this leads to the adaptation of populations to their environments. D) Niche partitioning is the process by which species divide resources to reduce competition within an ecosystem. While this can influence the evolution of species, it is not the process by which an organism adapts through inherited traits.
