Biology

1. What are the finger-like projections that increase the surface area for absorption in the small intestine called?

Correct answer: C

Rationale: Rationale: A) Crypts of Lieberkühn are small pits in the lining of the small intestine that contain cells involved in the production of intestinal juices, but they do not increase the surface area for absorption. B) Goblet cells are specialized cells that secrete mucus to protect the lining of the digestive tract, but they do not increase the surface area for absorption. C) Villi are finger-like projections in the small intestine that increase the surface area available for nutrient absorption. Each villus contains blood vessels and lacteals (lymphatic vessels) that help absorb nutrients from digested food. D) Paneth cells are specialized cells found in the small intestine that secrete antimicrobial substances, but they do not increase the surface area for absorption.

2. Which of the following situations represents work being done on an object?

Correct answer: c

Rationale: Work is done when a force is applied to move an object over a distance.

3. What is the building block of RNA?

Correct answer: B

Rationale: Rationale: A) Amino acid: Amino acids are the building blocks of proteins, not RNA. B) Nucleotide: Nucleotides are the building blocks of RNA. A nucleotide consists of a nitrogenous base (adenine, guanine, cytosine, or uracil in RNA), a sugar (ribose in RNA), and a phosphate group. C) Protein: Proteins are made up of amino acids, not nucleotides. D) Fatty acid: Fatty acids are components of lipids, not RNA.

4. The beautiful flowers brightened the room. Which word is the adverb form of the adjective "beautiful"?

Correct answer: B

Rationale: Adverbs are formed from adjectives by adding "-ly" (usually).

5. Which structure in the respiratory system is responsible for the exchange of oxygen and carbon dioxide between the lungs and the bloodstream?

Correct answer: C

Rationale: The correct answer is C, Alveoli. Alveoli are tiny air sacs located at the end of the bronchioles in the lungs where the exchange of oxygen and carbon dioxide takes place. Oxygen from the air we breathe diffuses into the bloodstream through the alveoli walls, while carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled. The trachea and bronchi are responsible for carrying air to and from the lungs, while bronchioles are small air passages within the lungs that branch off from the bronchi. However, the actual gas exchange occurs in the alveoli, making them crucial for the respiratory system's function.

6. 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.
