English Grammar

1. Which preposition best completes the sentence: "She borrowed money _____ her friend."

Correct answer: B

Rationale: "From" indicates the source of the borrowed money.

2. What is the function of introns in eukaryotic genes?

Correct answer: C

Rationale: Rationale: A) Introns do not code for protein sequences. Exons are the segments of DNA that code for proteins. B) While introns can indirectly influence gene regulation, their primary function is not directly involved in gene regulation. C) Introns are non-coding regions of DNA that are transcribed into pre-mRNA but are removed during mRNA processing through a process called splicing. This allows only the exons to be included in the mature mRNA that will be translated into proteins. D) While introns were once thought to be non-functional remnants of ancient DNA, research has shown that they can have regulatory functions and play a role in gene expression.

3. Which word best synonyms with the word "elated"?

Correct answer: C

Rationale: "Elated" and "excited" both convey feelings of happiness and enthusiasm.

4. Which type of waves exhibit both longitudinal and transverse motion?

Correct answer: b

Rationale: Surface waves, like those on water surfaces, exhibit both longitudinal and transverse motion.

5. Which of the following is NOT a type of intermolecular force?

Correct answer: C

Rationale: Ionic bonding is a type of intramolecular force, holding ions together within an ionic compound. Intermolecular forces are responsible for the interactions between individual molecules.

6. What is the main function of the epiglottis?

Correct answer: C

Rationale: Rationale: The epiglottis is a flap of cartilage located at the base of the tongue that covers the opening of the trachea during swallowing to prevent food and liquids from entering the airway. This action helps direct food and liquids into the esophagus, which leads to the stomach for digestion, while also protecting the respiratory system from potential blockages that could lead to choking or aspiration pneumonia. Options A, B, and D are incorrect as the epiglottis is not involved in storing bile, absorbing nutrients, or producing digestive enzymes.
