Cestoda is a parasite is known by having structures called scholex and proglottids.Question 20Answera.Trueb.False

The statement is true.

Here's a step-by-step explanation:

1. Cestoda is a class of parasitic worms in the flatworm phylum. They are commonly known as tapeworms.

2. Tapeworms have a unique body structure. The head, or scolex, has hooks and suckers for attaching to the intestinal wall of the host.

3. Behind the scolex, the body of the tapeworm consists of a long series of segments known as proglottids. Each proglottid contains reproductive organs, and they are continually produced by the neck region just behind the scolex.

4. As new proglottids are produced, older ones are pushed toward the end of the tapeworm and eventually break off. These can pass out of the host's body and spread the tapeworm's eggs into the environment.

So, the correct answer is a. True. Cestoda is a class of parasites known for having structures called a scolex and proglottids.
