Question

Suppose you use a microscope

to look at a tiny worm. What characteristics
would you look for to classify it?

Answer 1

I would look for body structure, what it eats, and how it feeds, and the circulatory system.

Step-by-step explanation:

Flatworms have a digestive system with only a single opening. They ingest food through the feeding tube, and also the undigested food exits through the feeding tube as well.

Roundworms and segmented worms have a tube-like digestive system that has two openings. Food enters through the mouth and waste exits through the anus.
