Imagine you are a scientist who has discovered a new organism on a scientific expedition. What specific characteristics would you investigate in order to determine if it is an animal? Correct Answer Some features to investigate would include the type of nutrition (autotrophy vs. heterotrophy), digestion (internal or external), movement, presence of sensory apparatus, the types of junctions between cells, presence of Hox genes, and the type of extracellular matrix present in the organism. Beca...
