1. ___________ is a symbiotic relationship in which one organism benefits and the other is not affected.

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

Correct answer: C

Rationale: The correct answer is 'Commensalism.' In commensalism, one organism benefits from the relationship while the other is neither helped nor harmed. This type of symbiotic relationship is characterized by one organism deriving a benefit, such as food or shelter, without impacting the other organism in any significant way. Choice A, 'Mutualism,' is a symbiotic relationship in which both organisms benefit. Choice B, 'Parasitism,' is a symbiotic relationship in which one organism benefits at the expense of the other. Choice D, 'Competition,' refers to a relationship in which organisms compete for limited resources, with both being affected in terms of access to resources.

2. What is the composition of the plasma membrane?

• A. Proteins
• B. Lipids
• C. Carbohydrates
• D. Nucleotides

Correct answer: B

Rationale: The plasma membrane is composed of lipids, proteins, and carbohydrates. While proteins are an essential component of the plasma membrane, it is not the only constituent. Carbohydrates and lipids also play crucial roles in the structure and function of the plasma membrane. Nucleotides are not part of the primary structural components of the plasma membrane, making this choice incorrect.

3. What is the best description of the word 'suppress'?

• A. stop
• B. push up
• C. release
• D. strain

Correct answer: A

Rationale: The correct answer is A: 'stop.' 'Suppress' means to stop or hold back something. Choice B, 'push up,' is incorrect as it does not accurately reflect the meaning of 'suppress.' Choice C, 'release,' is incorrect as it is the opposite of 'suppress.' Choice D, 'strain,' is also incorrect as it does not capture the meaning of 'suppress.'

4. Multiply: 54 × 45. Express the result in decimal form.

• A. 0.0243
• B. 0.243
• C. 2.43
• D. 24.3

Correct answer: D

Rationale: To multiply 54 by 45, you should multiply the two numbers together: 54 x 45 = 2430. The decimal point is placed after counting the total decimal places in the numbers being multiplied. As there are no decimal places in the numbers 54 and 45, the result is 2430, which is correctly expressed as 24.3 when considering the decimal point placement. Choice A (0.0243) and Choice B (0.243) are incorrect as they represent fractions of 2430. Choice C (2.43) is incorrect as it incorrectly places the decimal point one place before the actual result.

5. If a patient's condition is deteriorating, what is happening?

• A. They are improving
• B. They are getting worse
• C. They are stable
• D. They are recovering

Correct answer: B

Rationale: When a patient's condition is deteriorating, it means they are getting worse. This indicates a decline or worsening in their health status, requiring immediate attention or intervention. Choice A is incorrect because 'improving' means the opposite of deteriorating. Choice C is incorrect as 'stable' means there is no significant change. Choice D is incorrect as 'recovering' means getting better, which is the opposite of deteriorating.
