Most flukes belong to the subclass __________.

Explanation
Most flukes belong to the subclass Digenea. Digenea is a subclass of flatworms, specifically parasitic flukes. Flukes are a type of internal parasite that infects various animals, including humans. They have complex life cycles and are characterized by a leaf-like body shape. Digenea flukes have two suckers, one near the mouth and one on the ventral side, which they use to attach to their hosts. They are known for causing diseases such as schistosomiasis in humans.

Life history consists of _ different body forms, and at least _ different hosts.

2, 3
3,2
2,2
2,4

Correct Answer

A. 2,2

Explanation

Life history consists of two different body forms, which means that an organism goes through two distinct stages in its life cycle. Additionally, it involves two different hosts, indicating that the organism relies on two different species for its survival and reproduction.

Adult trematodes are ___ in the bloodstreams or digestive tracts of .

Correct Answer
endoparasites, vertebrates

Explanation
Adult trematodes are endoparasites, which means they live inside the body of their host. They can be found in the bloodstreams or digestive tracts of vertebrates. These parasites rely on their hosts for survival and obtain nutrients from them. By living inside the host, they can easily access the resources they need for their own growth and reproduction.
