Anatomy

1. The muscular tube connecting the mouth to the stomach is lined with a mucous membrane. What is the main function of this mucous membrane?

Correct answer: C

Rationale: The correct answer is C: Lubrication and protection. The mucous membrane lining the esophagus serves to provide lubrication for food as it travels from the mouth to the stomach, making it easier to swallow. Additionally, the mucous membrane protects the esophageal tissue from damage caused by the passage of food and liquids. This function is crucial in preventing irritation and inflammation of the esophagus, ensuring smooth and efficient digestion process. The mucous membrane does not secrete digestive enzymes (A), absorb nutrients (B), or store bile (D), as those functions are carried out by other digestive organs.

2. What is the primary function of ribosomes in the cell?

Correct answer: D

Rationale: Rationale: Ribosomes are cellular organelles responsible for protein synthesis. They read the genetic information encoded in messenger RNA (mRNA) and use this information to assemble amino acids into a specific sequence, forming a protein. This process is known as translation and is essential for the production of proteins that carry out various functions in the cell. Options A, B, and C do not accurately describe the primary function of ribosomes in the cell.

3. A block slides down a frictionless inclined plane. What determines its final velocity at the bottom?

Correct answer: B

Rationale: In the absence of friction, the final velocity depends only on the gravitational potential energy gained, which is determined by the height difference related to the angle of the incline.

4. What type of figurative language is used in the statement "Her laughter was music to my ears"?

Correct answer: A

Rationale: The statement directly compares laughter to music, forming a metaphor.

5. A rectangular bandage measures 5cm by 8cm. What is the area covered by the bandage?

Correct answer: C

Rationale: 40cm^2: Multiply the length (5cm) by the width (8cm).

6. What is the meaning of the idiom "to bite off more than one can chew"?

Correct answer: B
