1. Imagine you have an element with atomic number 11 and mass number 23. How many neutrons does it have?

• A. 11
• B. 12
• C. 23
• D. 21

Correct answer: B

Rationale: - The atomic number (Z) of an element is the number of protons in its nucleus. In this case, the element has an atomic number of 11. - The mass number (A) of an element is the sum of its protons and neutrons. Given that the mass number is 23 and the atomic number is 11, we can calculate the number of neutrons by subtracting the atomic number from the mass number: Neutrons = Mass number - Atomic number = 23 - 11 = 12. - Therefore, the element with atomic number 11 and mass number 23 has 12 neutrons.

2. With which genotype would the recessive phenotype appear if the dominant allele is marked with 'A' and the recessive allele is marked with 'a'?

• A. AA
• B. aa
• C. Aa
• D. aA

Correct answer: B

Rationale: The recessive phenotype appears when an individual has two copies of the recessive allele. In this case, the recessive allele is marked with 'a.' Therefore, the genotype 'aa' would display the recessive phenotype as both alleles are recessive. Choice A (AA) has two dominant alleles, choice C (Aa) has one dominant and one recessive allele, and choice D (aA) represents the same genotype as Aa due to the principle of allele dominance.

3. Identify the adverb in the following sentence:

• A. waited
• B. anxiously
• C. doctor's
• D. news

Correct answer: B

Rationale: An adverb modifies verbs, adjectives, or other adverbs. In this sentence, 'anxiously' describes how the patient 'waited'. Therefore, the adverb in the sentence is 'anxiously'. Choice A, 'waited', is a verb and not an adverb. Choice C, 'doctor's', is a possessive noun and not an adverb. Choice D, 'news', is a noun and not an adverb. The correct adverb that modifies the verb 'waited' in the sentence is 'anxiously'.

4. What element is responsible for the red color of blood?

• A. Magnesium
• B. Iron
• C. Copper
• D. Zinc

Correct answer: B

Rationale: The correct answer is B: Iron. Hemoglobin, the protein responsible for carrying oxygen in red blood cells, contains iron in its heme group, contributing to the blood's characteristic red color. Magnesium (choice A), copper (choice C), and zinc (choice D) are not responsible for the red color of blood. Magnesium is an essential mineral involved in various physiological processes, copper is a trace element important for enzyme function, and zinc is a micronutrient essential for multiple cellular functions but not related to the red color of blood.

5. Which of the following quotes offers the best summary for the instructor's motive in sending the email to the students?

• A. By now, many of you have probably seen your grade and are a little concerned. (And if you're not concerned, you should be-at least a bit!)
• B. With each class comes a new challenge, however, and as any good instructor will tell you, sometimes the original plan has to change.
• C. The purpose of the group project is to allow students to work together and arrive at a stronger response than if each worked individually.
• D. At the beginning of the semester, I informed the class that I have a strict grading policy and that all scores will stand unquestioned.

Correct answer: B

Rationale: The correct answer is B. This quote best captures the instructor's motive in the email to adjust the original plan to better support the students. Dr. Edwards is offering alternative options, including extra credit projects and a group project, to help students improve their scores after the essay exam. These options aim to provide students with opportunities to enhance their grades and succeed in the course. Choice A focuses on students feeling concerned about their grades but does not address the instructor's motive. Choice C highlights the purpose of the group project but does not capture the instructor's motive for sending the email. Choice D emphasizes the instructor's strict grading policy but does not explain the motive behind offering alternative ways to improve scores.
