Question

A terrestrial animal species is discovered with the following larval characteristics: exoskeleton, system of tubes for gas exchange, and modified segmentation. A knowledgeable zoologist should predict that the adults of this species would also feature __________.

a. eight legs.b. two pairs of antennae.c. a sessile lifestyle.d. an open circulatory system.e. parapodia.

Answer 1

A knowledgeable zoologist should predict that the adults of this species would also feature d. an open circulatory system

Step-by-step explanation:

Having an open circulatory system means that the organisms with this type of systems don't have true blood but a mix of different fluids. It is common among small animals such as arthropods. Larval characteristics such as exoskeleton, system of tubes for gas exchange, and modified segmentation, make us think of an open circulatory system, because we are in need of that "extra" system of tubes for gas exchange.
