A: Metalloids are chemical elements that have properties common with both metals and nonmetals. Some metalloid semiconductors are able to carry an electrical charge under the right conditions, a property that allows them to be used in the production of computers and other electronic devices.

The scientific term for sponges is Porifera, which literally means pore-bearing. The surface of a sea sponge is made up of thousands of tiny pores, called ostia. These pores lead internally to a system of canals, whose main functions are collecting nutrients and oxygen, and disposing waste and carbon dioxide. sea sponge's body primarily consists of spicules and spongin. Spicules are needle shaped fiberlike structures that act as the sponge's skeleton. Spongin is a protein that helps provide body support. In some instances the spongin will combine with the spicules to provied support, in other times the spongin works alone.
