Answer:

Presence of radula in buccal cavity

Answer 2

Chaetopleura differs from leech in d) presence of radula in the buccal cavity.

Explanation:

• The leech digestive tract is comprised of three major regions, the pharynx, crop, and intestine, with each region performing distinct functions.
• The pharynx is a muscular region located immediately downstream of the jaws and adjacent to the salivary glands.
• The radula in chaetopleura is an anatomical structure used for feeding, sometimes compared to a tongue.
• It is a minutely toothed, chitinous ribbon, typically used to scrap or cut food before the food enters the esophagus.
