English Grammar

1. Choose the correct pronoun to complete the sentence: "Neither Michael nor Sarah ____ their homework finished yet."

Correct answer: B

Rationale: When referring to "neither" followed by two subjects, the verb agrees with the plural subject ("Sarah"). So, "have" is the correct answer.

2. Which of the following glands is NOT directly controlled by the pituitary gland?

Correct answer: C

Rationale: The correct answer is C. The pituitary gland is often referred to as the 'master gland' because it secretes hormones that control the functions of other endocrine glands. The thyroid gland (A), adrenal glands (B), and parathyroid glands (D) are directly controlled by the pituitary gland through the release of specific hormones. However, the pancreas, specifically the islets of Langerhans (C), is not directly controlled by the pituitary gland. The pancreas is regulated by hormones such as insulin and glucagon, which are not secreted by the pituitary gland. Therefore, option C is the correct answer as it is not directly influenced by the pituitary gland's hormonal regulation.

3. What are the three main types of RNA?

Correct answer: A

Rationale: Rationale: - Messenger RNA (mRNA) carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm for protein synthesis. - Ribosomal RNA (rRNA) is a structural component of ribosomes, which are the cellular machinery responsible for protein synthesis. - Transfer RNA (tRNA) is responsible for bringing amino acids to the ribosome during protein synthesis. Options B, C, and D are incorrect: - Option B lists DNA, RNA, and protein, which are biomolecules but not the three main types of RNA. - Option C lists nitrogenous bases (adenine, guanine, cytosine, and thymine) found in DNA, not types of RNA. - Option D lists components of nucleotides (deoxyribose, ribose, and phosphate), which are building blocks of nucleic

4. Which structure in the heart is responsible for preventing the backflow of blood from the left ventricle into the left atrium?

Correct answer: D

Rationale: The correct answer is D, the Mitral valve. The Mitral valve, also known as the bicuspid valve, is located between the left atrium and left ventricle in the heart. It consists of two cusps that close tightly when the left ventricle contracts, preventing the backflow of blood into the left atrium. The aortic valve (option A) is responsible for preventing the backflow of blood from the aorta into the left ventricle, not the left atrium. The pulmonary valve (option B) prevents backflow from the pulmonary artery into the right ventricle, and the tricuspid valve (option C) prevents backflow from the right ventricle into the right atrium. Therefore, the Mitral valve is specifically responsible for preventing backflow from the left ventricle into the left atrium.

5. What happens to the frequency of a wave if its wavelength decreases while the speed remains constant?

Correct answer: b

Rationale: If the speed of the wave remains constant while the wavelength decreases, the frequency of the wave increases.

6. Which word is most closely associated with the adjective "ambiguous"?

Correct answer: B

Rationale: "Ambiguous" implies uncertainty or multiple interpretations, making "vague" its closest synonym.
