Be familiar with the common characteristics of animals. Answer- - Multicellular heterotrophs - cells lack cell walls -most have nerves, muscles, and capacity to move at some point in the life cycle - able to reproduce sexually - specialized sensory structures and nervous system - cells exist in extensive extracellular matrix - unique cell junctions What type of life cycle do all animals show? Answer- gametic What is the most likely ancestor of animals? Answer- choanoflagellates What...
