Question

Katrina drew a diagram to compare roundworms and flatworms.

Which label belongs in the area marked Y?
A.) Reproduce sexually
B.) Are usually very small
C.) Can grow to twelve meters
D.) Are always parasitic​

Answer 1

Answer: I think is D

Step-by-step explanation:

Most flatworms are parasites that obtain their food from a host animal. A parasite

lives inside or on another living organism. Sometimes a parasite will kill its host,

but usually the host survives. Flatworms' bodies are flat and as soft as jelly. Some

common ones are planarians, flukes, and tapeworms.
