1. What is the term for a solution with a pH value less than 7?

• A. Acidic
• B. Neutral
• C. Alkaline
• D. Basic

Correct answer: a

Rationale: Solutions with a pH less than 7 are acidic. The other choices do not accurately describe solutions with a pH less than 7.

2. What is the process of converting DNA into a protein called?

• A. Transcription
• B. Translation
• C. Replication
• D. Mutation

Correct answer: A

Rationale: Transcription is the process of converting DNA into a molecule called messenger RNA (mRNA). This mRNA molecule carries the genetic information from DNA to the ribosomes, where it is used to make proteins.

3. The van't Hoff factor (i) accounts for the number of particles a solute dissociates into in solution. For a compound that dissociates completely in water, i would be...

• A. 0
• B. Less than 1
• C. 1
• D. More than 1

Correct answer: C

Rationale: The van't Hoff factor (i) is used to account for the number of particles a solute dissociates into in solution. For a compound that dissociates completely in water, such as a strong electrolyte, i would be equal to the total number of ions produced by the dissociation. Since the compound dissociates completely, it forms an equal number of ions, resulting in an i value of 1. Therefore, the correct answer is C: 1.

4. Which of the following is NOT a characteristic of living organisms?

• A. Made up of cells
• B. Able to reproduce
• C. Require energy
• D. Non-motile

Correct answer: D

Rationale: Rationale: A) Made up of cells: All living organisms are composed of one or more cells. This is a fundamental characteristic of life as defined by cell theory. B) Able to reproduce: One of the key characteristics of living organisms is their ability to reproduce and pass on genetic information to offspring. C) Require energy: Living organisms require energy to carry out various life processes such as growth, reproduction, and maintenance of homeostasis. This energy is obtained through processes like metabolism. D) Non-motile: While some living organisms may be non-motile (unable to move on their own), movement is a common characteristic of many living organisms. Motility allows organisms to respond to their environment, find food, escape predators, and carry out other essential activities.

5. 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.

6. You design an experiment to test the effect of temperature on plant growth. Which variable should you keep constant?

• A. The type of soil used.
• B. The amount of sunlight the plants receive.
• C. The amount of water given to the plants.
• D. The temperature variations being tested.

Correct answer: A

Rationale: In this experiment, the variable being tested is the effect of temperature on plant growth. To ensure that any observed changes in plant growth are due to temperature variations and not other factors, it is important to keep other variables constant. The type of soil used can significantly impact plant growth, so it should be kept constant to isolate the effect of temperature. Keeping the amount of sunlight and water constant would also help ensure that any differences in plant growth are due to temperature variations.
