Question

An earthworm's body consists of a number of fluid-filled compartments, each with its own set of longitudinal and circular muscles. But in the roundworm, a single fluid-filled cavity occupies the body, and there are only longitudinal muscles that run its entire length. Predict how the movement of a roundworm would differ from the movement of an earthworm.

Accepted Answer

Hey everyone, Let's take a look at this question together which body structure of earthworms rips the ground and provides traction as they move. Let's recall what we know about the structure of earthworms. To try to figure out what structure is the one that grips the ground and provides the traction as they move. So looking at this body structure of the earthworm, we can see down here we have these little legs at the bottom and that's what is providing the traction when they move as well as gripping the ground. And so the name for these little feet at the bottom are called bristles. Or answer choice A The correct answer because we know that in the structure of the earthworm, the bristles are what gripped the ground and provide the traction as they move along. And so that means answer choice A is our correct answer. I hope you found this video to be helpful. Thank you and goodbye.
