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 phylum porifera consists of the sponges to make it into the porifera phylum an animal must have no true tissuesome contain spicules a skeletal element and all contain choanocysts a type of cell which move water through the porous bodies of poriferasporifera also have totipotent cells which have the cabalitity of changing into whatever type of cell is needed by the organismhe phylum porifera consists of the sponges to make it into the porifera phylum an animal must have no true tissue
