1. When proofreading your writing, focus on:

• A. Changing the wording to sound more original.
• B. Ignoring minor grammatical errors like typos.
• C. Checking for clarity, consistency, and overall flow.
• D. Replacing common words with thesaurus alternatives.

Correct answer: C

Rationale: Proofreading involves correcting errors, refining sentence structure, and ensuring the writing achieves its purpose, clarity, and consistency.

2. What is the scientific name for the common housefly?

• A. Musca domestica
• B. Drosophila melanogaster
• C. Apis mellifera
• D. Anopheles gambiae

Correct answer: A

Rationale: Rationale: - Musca domestica is the scientific name for the common housefly. This species is known for being a common pest found in and around human habitations. - Drosophila melanogaster (option B) is a species of fruit fly commonly used in genetic research. - Apis mellifera (option C) is the scientific name for the western honeybee. - Anopheles gambiae (option D) is a species of mosquito known for being a vector of malaria.

3. The process of a liquid changing into a gas is called:

• A. Evaporation
• B. Boiling
• C. Condensation
• D. Sublimation

Correct answer: A

Rationale: Evaporation occurs at any temperature, while boiling only occurs at the boiling point of the liquid.

4. What is the main function of the endoplasmic reticulum (ER) in the cell?

• A. To synthesize and transport proteins and lipids
• B. To package and transport proteins
• C. To break down macromolecules
• D. To store genetic material

Correct answer: A

Rationale: Rationale: A) The endoplasmic reticulum (ER) is a network of membranes within the cell that plays a crucial role in protein and lipid synthesis. It consists of two types: rough ER, which is studded with ribosomes and involved in protein synthesis, and smooth ER, which is involved in lipid synthesis and detoxification. The ER also plays a role in transporting these synthesized proteins and lipids to other parts of the cell or outside the cell. B) While the ER is involved in packaging proteins, the main function is not solely to package and transport proteins. This function is more associated with the Golgi apparatus. C) Breaking down macromolecules is primarily the function of lysosomes, which are membrane-bound organelles containing enzymes for digestion. D) Storing genetic material is the function of the nucleus, which houses the cell's DNA. The ER is not involved in storing

5. What is the main function of dietary fiber in the digestive system?

• A. To provide energy
• B. To break down fats
• C. To promote gut bacteria growth
• D. To aid in absorption of nutrients

Correct answer: C

Rationale: Rationale: Dietary fiber refers to the indigestible portion of plant foods that passes relatively intact through the digestive system. While fiber does not provide energy directly to the body, it plays a crucial role in promoting the growth of beneficial gut bacteria. These bacteria help in the fermentation of fiber, producing short-chain fatty acids that can be used as an energy source by the body. Additionally, fiber helps regulate bowel movements, maintain gut health, and support overall digestive function. Therefore, the main function of dietary fiber in the digestive system is to promote gut bacteria growth.

6. What is the relationship between the speed of a wave, its frequency, and wavelength in a given medium?

• A. Speed = Frequency × Wavelength
• B. Speed = Frequency ÷ Wavelength
• C. Speed = Frequency + Wavelength
• D. Speed = Frequency - Wavelength

Correct answer: a

Rationale: In a given medium, the speed of a wave equals the product of its frequency and wavelength.
