1. What kind of symbiosis exists between a pneumonia bacterium and a human?

• A. Mutualism
• B. Parasitism
• C. Commensalism
• D. Competition

Correct answer: B

Rationale: In the case of a pneumonia bacterium and a human, the relationship is best described as parasitism. The bacterium benefits by causing harm to the human host, while the human is negatively affected by the presence of the bacterium, leading to illness or infection. This is a classic example of a parasitic relationship where one organism benefits at the expense of the other. Mutualism (Choice A) is a type of symbiotic relationship where both organisms benefit from each other. Commensalism (Choice C) is a symbiotic relationship where one organism benefits, and the other is neither helped nor harmed. Competition (Choice D) refers to a relationship where both organisms are negatively affected by each other as they compete for resources.

2. Which of the following is true of homozygous traits?

• A. They are haploid
• B. They are denoted AA
• C. They are denoted aa
• D. They are denoted Aa

Correct answer: B

Rationale: Homozygous traits have two identical forms of the gene, either both dominant (AA) or both recessive (aa). Therefore, choices B and C are true for homozygous traits. Choice A is incorrect because being haploid refers to having a single set of chromosomes, not necessarily homozygous traits. Choice D is incorrect as homozygous traits have identical alleles, so they are not denoted as Aa.

3. What does 'Contour' mean?

• A. Flat area
• B. Shape or outline of something
• C. Volume of a structure
• D. Height of a structure

Correct answer: B

Rationale: The term 'Contour' specifically refers to the shape or outline of something. In art and geography, contours are used to represent the outline or shape of an object or landform, making choice B the correct definition. Choice A, 'Flat area,' is incorrect as it does not capture the essence of contour which is about the shape or outline. Choice C, 'Volume of a structure,' is unrelated to the concept of contour. Choice D, 'Height of a structure,' is also incorrect as contour is more about the shape and not the height of an object.

4. Select the sentence that is grammatically correct.

• A. Dr. Chu told me and her to take a break for lunch.
• B. Dr. Chu told her and me to take a break for lunch.
• C. Dr. Chu told her and me to take a break for lunch.
• D. Dr. Chu told she and I to take a break for lunch.

Correct answer: B

Rationale: The correct pronouns to use as objects of the verb 'told' are 'her' and 'me.' Therefore, the grammatically correct sentence is: 'Dr. Chu told her and me to take a break for lunch.' 'Her' is used as the object form of 'she,' and 'me' is the object form of 'I' in this context. Choice A is incorrect because 'me' should come before 'her' in the sentence. Choice C is a duplicate of the correct answer. Choice D is incorrect because 'she' should be 'her' and 'I' should be 'me' to function as objects in the sentence.

5. The Ramifications of a course of treatment are that treatment's ______

• A. Effectiveness
• B. Consequences
• C. Complications
• D. Outcomes

Correct answer: B

Rationale: The correct answer is 'B: Consequences.' Ramifications refer to the consequences of a particular course of action or treatment. In this context, 'Effectiveness' (Choice A) is not the most appropriate term as ramifications are more about the results or outcomes beyond just effectiveness. 'Complications' (Choice C) are adverse effects or issues that arise, not necessarily the overall consequences. 'Outcomes' (Choice D) is close in meaning but not as synonymous with ramifications as 'Consequences' is.
