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
Circulatory System: Porifera do not have a circulatory system. Type of Symmetry: Porifera are most commonly asymmetrical but can also have radial symmetry. Type of Coelom: Porifera have no coelom. Type of Body Plan: Porifera use canals and pores (diffusion) to perform life functions. Number of body layers: Porifera have no real body layers but they do have 2 cell layers; an outer layer that makes up the epidermis, and an inner layer that makes the inner cavities. Specialized Cells: Porifera have
