Most adult echinoderms have which of the following? a. two-part bilateral symmetry b. five-part bilateral symmetry c. five-part radial symmetry d. an asymmetrical body

five-part radial symmetry

Explanation:

Echinoderms are non - chordates and mainly [present at the inner depth of the ocean. Echinoderms are deuterostomes, in which the anus develops first and mouth development takes place after the anus development.

Echinoderm animals do not live in freshwater or terrestrial (on land). The adults of the echinoderm can be easily identified by the five part- radial symmetry.

Thus, the correct answer is option (C).

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
