1. What is the function of ribosomal RNA (rRNA)?

• A. Carries amino acids to the ribosomes
• B. Reads th(a) Carries amino acids to the ribosomes: This is the function of transfer RNA (tRNA), not ribosomal RNA. (b) Reads the genetic code on mRNA: This is the function of the ribosomes as a whole, not just the ribosomal RNA. (d) Controls the rate of protein synthesis: This is a more complex process involving various factors, not solely ribosomal RNA. e genetic code on mRNA
• C. Forms the structural framework of ribosomes
• D. Controls the rate of protein synthesis

Correct answer: C

Rationale: Rationale: Ribosomal RNA (rRNA) plays a crucial role in forming the structural framework of ribosomes, which are the cellular organelles responsible for protein synthesis. Ribosomes consist of both protein and rRNA components, with rRNA providing the structural support necessary for the ribosome to function properly. This structural framework allows the ribosome to interact with messenger RNA (mRNA) and transfer RNA (tRNA) during the process of translation, where the genetic information encoded in mRNA is used to assemble proteins from amino acids. Therefore, the primary function of rRNA is to contribute to the structure and function of ribosomes, rather than directly carrying amino acids, reading the genetic code, or controlling the rate of protein synthesis.

2. A kite has a top base of 20cm, a bottom base of 30cm, and two equal side lengths of 15cm. What is its perimeter?

• A. 55cm
• B. 65cm
• C. 70cm
• D. 80cm

Correct answer: C

Rationale: Add the lengths of all sides: perimeter = top base + bottom base + 2 * side length = 20cm + 30cm + 2 * 15cm = 70cm.

3. Which property of a substance describes how much matter is packed into a given space?

• A. Mass
• B. Volume
• C. Weight
• D. Density

Correct answer: D

Rationale: Density is the property of a substance that describes how much matter is packed into a given space. It is calculated by dividing the mass of the substance by its volume. Mass refers to the amount of matter in an object, volume is the amount of space an object occupies, and weight is the force of gravity acting on an object's mass. Density specifically relates to how tightly packed the particles of a substance are.

4. Which sentence uses comma splices incorrectly?

• A. The baker kneaded the dough, flour dusted her apron, and the oven warmed up.
• B. The mountains, shrouded in mist, seemed to disappear into the clouds.
• C. He arrived late, having forgotten his keys, and the meeting had already started.
• D. The movie, despite its flaws, was surprisingly enjoyable.

Correct answer: C

Rationale: Option (c) incorrectly combines two independent clauses with only a comma. A semicolon or conjunction is needed

5. There are times when Katherine evaluates her staff as she makes her daily rounds. Which of

• A. The staff member is observed in natural setting.
• B. Incidental confrontation and collaboration is allowed.
• C. The evaluation is focused on objective data systematically.
• D. The evaluation may provide valid information for compilation of a formal report.

Correct answer: A

Rationale: The correct answer is A: 'The staff member is observed in a natural setting.' This option is the most appropriate because it aligns with the concept of naturalistic observation, where behavior is observed in its natural environment without interference or manipulation. In this scenario, Katherine is observing her staff during her daily rounds without any alterations to their behavior or environment. This allows for a more authentic and unbiased assessment of their performance. Options B, C, and D are not as relevant to the concept of naturalistic observation and do not accurately describe the situation presented in the question.

6. She tries to design an organizational structure that allows communication to flow in all

• A. Centralized
• B. Decentralized
• C. Matrix
• D. Informal

Correct answer: A

Rationale: The correct answer is 'A: Centralized.' In a centralized organizational structure, decision-making authority and communication flow through a single point of control or a specific group of individuals. This setup ensures that communication channels are streamlined and information is disseminated efficiently. By designing an organizational structure that allows communication to flow in all directions, it suggests a decentralized structure where decision-making authority is distributed across various levels and departments. Therefore, 'Centralized' is the best fit for the scenario described in the question.
