QUICK I NEED THE ANSWER!! Compare the symmetry of an echinoderm to the symmetry of worms

A. Both echinoderms and worms have bilateral symmetry

B. Echinoderms have bilateral symmetry and worms have radial symmetry

C. Echinoderms have radial symmetry and worms have bilateral symmetry

D. Both echinoderms and worms have radial symmetry

C.Echinoderms have radial symmetry and worms have bilateral symmetry

Explanation:

Echinoderms evolved from animals with bilateral symmetry. The larvae of all echinoderms are bilaterally symmetrical but lost during metamorphosis  developing into radial symmetry adult. Examples of echinoderms are  starfish, sea urchins, sand dollars.

Worms are invertebrate animals having bilateral symmetry. They have a definite anterior (head) end and a posterior (tail) end. Worms have brains that help them detect objects, food,  mates, and predators quickly.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
