Sensory cells and sensory neurons allow multicellular animals to sense physical and chemical cues from their environment. What key properties of these cells enable them to perform this function?
A)Sensory cells and sensory neurons have electrically excitable membranes that change in charge potential in response to binding an environmental signaling molecule.
B)Sensory neurons have myelinated dendrites that serve as nerve endings.
C)All sensory cells and sensory neurons fire action potentials when they bind a signaling molecule.
D)Sensory cells and sensory neurons have protein receptors linked to intracellular or membrane-based signaling pathways that alter ion channel permeability.
