Question

Quizplus · Accepted Answer

The statement that the Acari are of great economic and medical importance is the only true statement about them. The other statements are inaccurate. The Acari do not have a distinct head, thorax, and abdomen, but rather have a combined body structure. There are actually around 50,000 species of Acari, making them far from a limited order of organisms. Additionally, some Acari live in aquatic environments.
