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.

Why, you ask? Well, the term Porifera is actually the scientific name given to the group of organisms known commonly as sponges. But, unlike SpongeBob, living sponges are neither square in shape nor in interest-they are actually a really important and diverse phylum within the animal kingdom.owever, here we will focus on the key features of Porifera: choanocytes and spicules (formed by sclerocyte cells). Choanocytes, also known as collar cells, derive their name from the collar-like base where the flagellum (or tail) protrudes.
