English Grammar

1. Which of the following phrases is grammatically correct and uses parallel structure?

Correct answer: B

Rationale: Option B uses the gerund (-ing) form for all three hobbies, achieving parallel structure.

2. What is the main function of the gallbladder?

Correct answer: A

Rationale: Rationale: The gallbladder is a small organ located beneath the liver that plays a crucial role in the digestive system. Its main function is to store and concentrate bile, a digestive fluid produced by the liver. Bile is released from the gallbladder into the small intestine to help with the digestion and absorption of fats. The gallbladder acts as a reservoir for bile, allowing it to be released in a controlled manner when needed to aid in the digestion of fatty foods. Therefore, option A is the correct answer as it accurately describes the main function of the gallbladder.

3. Identify the interrogative sentence in the following options:

Correct answer: B

Rationale: An interrogative sentence asks a question and typically ends with a question mark.

4. What is the name of the muscular ring that controls the passage of food from the esophagus to the stomach?

Correct answer: B

Rationale: The correct answer is B: Cardiac sphincter. The cardiac sphincter, also known as the lower esophageal sphincter, is the muscular ring located at the junction between the esophagus and the stomach. It controls the passage of food from the esophagus into the stomach by opening and closing to prevent reflux of stomach contents back into the esophagus. The other options are incorrect: A) The pyloric sphincter is located at the junction between the stomach and the small intestine, controlling the passage of food from the stomach into the small intestine. C) The ileocecal valve is located between the small intestine and the large intestine. D) The Sphincter of Oddi is located in the duodenum and regulates the flow of bile and pancreatic juice into the small intestine. Therefore, the correct answer is B because it specifically relates to the passage of food from the esophagus to the stomach.

5. Vaccines work by stimulating the immune system to develop memory without causing full-blown illness. What type of molecule in a vaccine typically triggers the immune response?

Correct answer: D

Rationale: The correct answer is D: Antigens (specific molecules) from the pathogen. Vaccines contain antigens, which are specific molecules from the pathogen that trigger the immune response without causing the full-blown illness. By presenting these antigens to the immune system, vaccines stimulate the production of memory cells that can recognize and combat the pathogen in the future. Options A, B, and C are incorrect because vaccines typically do not contain toxins, live attenuated forms, or inactivated forms of the pathogen. Instead, they contain specific antigens to induce an immune response without causing the actual disease.

6. How many amino acids can make up a protein?

Correct answer: A

Rationale: Rationale: Proteins are made up of long chains of amino acids. There are 20 standard amino acids that are commonly found in proteins. The sequence and arrangement of these amino acids determine the structure and function of a protein. While proteins can vary in size and complexity, the number of amino acids typically ranges from around 10 to 20 in smaller proteins to hundreds or even thousands in larger proteins. Therefore, the range of 10-20 amino acids is the most accurate representation of the number of amino acids that can make up a protein.
