The correct answer is: c. chordates are more closely related to echinoderms than to arthropods
The Closest nonchordate relatives to Chordates are Echinodermata. Hemichordates (such as acorn worms) and Echinodermata form the Ambulacraria which is the sister phylum of the Chordates.
Echinoderms and chordates are both deuterostomes, but the differences are that Echinoderm possess bilateral symmetry only as larvae, they have tube feet and their bodies are supported by calcite skeletons.

Answer:Cells of the digestive system are vastly different in structure and function from cells of the skeletal system. Cells of the body depend on each other to keep the body functioning as a unit.
Typically, higher order streams contain MORE water than lower order streams.
Stream ordering is a mean of classifying natural channels in a water shed based on their sizes. The first order stream is the smallest stream and the second order stream is bigger than the first. Thus, the amount of water in the first order stream will be less that that of second order.<span />
