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.

Increased co-ordination between colonial cells appeared with the evolution of the sponges (Porifera). Sponges are considered the oldest living animal phylum.The name Porifera means pore bearer in Latin. Sponges may be formless lumps on the sea floor reaching two metres in size. Their surfaces are covered with tiny pores through which water is drawn into the body by flagella and then expelled through larger vents.ponges are considered the oldest living animal phylum.
