1. Which type of transport allows for the movement of large molecules, such as proteins and polysaccharides, across the cell membrane?

Correct answer: A

Rationale: Rationale: A) Endocytosis is the process by which cells engulf large molecules or particles by wrapping the cell membrane around them to form a vesicle that is brought into the cell. This mechanism allows for the movement of large molecules, such as proteins and polysaccharides, across the cell membrane. B) Exocytosis is the opposite process of endocytosis, where cells release large molecules or particles by fusing vesicles with the cell membrane to expel their contents out of the cell. C) Active transport is a process that requires energy to move molecules across the cell membrane against their concentration gradient. While active transport can move large molecules, it is not specifically designed for the transport of proteins and polysaccharides. D) Facilitated diffusion is a type of passive transport that involves the movement of molecules across the cell membrane with the help of transport proteins. While facilitated diffusion can assist in the movement of

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

Correct answer: A

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

3. What is the term for the process of separating the components of a solution based on their different rates of movement through a medium?

Correct answer: c

Rationale: Chromatography is a technique used to separate the components of a solution based on their different rates of movement through a medium. The other choices are different separation techniques.

4. 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.

5. Identify the reflexive pronoun in the sentence: "She prepared herself for the presentation."

Correct answer: A

Rationale: "Herself" refers back to the subject "she," making it a reflexive pronoun.

6. What is the general formula for an alkene?

Correct answer: B

Rationale: The general formula for an alkene is \(C_nH_{2n}\), indicating the presence of a double bond between carbon atoms.
