The evolution of which characteristic allowed for the development and enlargement of complex internal organs? a. segmentation b. tissue c. body cavity d. exoskeleton

D. exoskeleton

Explanation:

The exoskeleton is the hard outer covering of the body which provides protection to the internal structure of the organism against the injury, predation, and severe weather conditions. The parts of the exoskeleton includes the nails, hooves, shells and others. The evolution of exoskeleton has supported the growth and development of the internal structures of the organisms.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
