Questions: hold molecules of food in position (A) taste pore B taste sensor (C) microvilli (D) papillae

The answer is (C): microvilli.

Explanation:

• (A) taste pore: This is an opening on the surface of the tongue that allows molecules to enter and interact with taste receptors, but it does not hold molecules in position.
• (B) taste sensor: This term is not specific; it could refer to taste receptors or cells involved in taste, but it does not specifically hold molecules in position.
• (C) microvilli: These are tiny hair-like structures on the surface of taste receptor cells that increase the surface area and help hold molecules of food in position for tasting.
• (D) papillae: These are structures on the tongue that contain taste buds, but they do not directly hold molecules of food in position.

Therefore, the correct answer is (C) microvilli.
