1. How does an unbalanced force affect an object at rest?

• A. It maintains the object's state of rest
• B. It does not affect the object's rest
• C. It moves the object into motion
• D. It decreases the object's mass

Correct answer: c

Rationale: An unbalanced force acting on an object at rest causes it to start moving.

2. Which of the following factors would increase the solubility of a gas in a liquid?

• A. Decreasing temperature
• B. Increasing pressure
• C. Decreasing surface area
• D. Increasing particle size

Correct answer: b

Rationale: Henry's law states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. The other choices would typically decrease solubility.

3. What is the function of the underlined phrase "with a mischievous grin" in the sentence "He approached her with a mischievous grin, his eyes twinkling"?

• A. Subject
• B. Direct object
• C. Adverbial phrase
• D. Appositive phrase

Correct answer: C

Rationale: The underlined phrase modifies the verb "approached" by describing his manner, making it an adverbial phrase.

4. When writing dialogue, remember to:

• A. Avoid contractions and informal language for realism.
• B. Use formal vocabulary to sound sophisticated.
• C. Create realistic speech patterns reflecting the characters' personalities.
• D. Focus on descriptive narrative over character interactions.

Correct answer: C

Rationale: Effective dialogue captures the characters' unique voices and personalities through realistic speech patterns and word choices.

5. What is the process by which muscle tissue wastes away due to disuse or lack of nutrients?

• A. Hypertrophy
• B. Atrophy
• C. Fibrosis
• D. Rigor mortis

Correct answer: B

Rationale: The correct answer is B: Atrophy. Atrophy is the process by which muscle tissue wastes away due to disuse or lack of nutrients. When muscles are not regularly used or do not receive enough nutrients, they can decrease in size and strength. Hypertrophy, on the other hand, refers to the increase in muscle size and strength through exercise and proper nutrition. Fibrosis is the formation of excess fibrous connective tissue in an organ or tissue, leading to scarring. Rigor mortis is a temporary stiffening of muscles that occurs after death. Therefore, in this context, atrophy best describes the wasting away of muscle tissue due to disuse or lack of nutrients.

6. Which of the following organelles is responsible for the production of proteins in the cell?

• A. Ribosomes
• B. Golgi apparatus
• C. Mitochondria
• D. Lysosomes

Correct answer: A

Rationale: The correct answer is A: Ribosomes. Ribosomes are the organelles responsible for protein synthesis in the cell. They are found in both prokaryotic and eukaryotic cells and can be free-floating in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes read the messenger RNA (mRNA) and translate the genetic code into proteins through a process called translation. The Golgi apparatus is involved in processing and packaging proteins for secretion, while mitochondria are responsible for energy production. Lysosomes are involved in digestion and waste removal within the cell.
