Check all that apply to chemical synapses. chemical synapses are the most numerous type of synapse in the human body. chemical synapses are found primarily in smooth muscle cells. chemical synapses are unidirectional (one way). chemical synapses allow two-way signaling

-Chemical synapse are the most numerous type of synapse in the human body
-chemical synapse are unidirectional

Chemical synapse are specialized junction by which cells of the nervous system signal to one another and also to non neuronal cells such as muscles and glands. This also allows the neurons of the central nervous system to form interconnected neural circuits. They are crucial to biological computations and provide means to connect and control other systems in the body.

Plants take energy from the sunlight with the of chlorophyll so the plant starts the food chain. then an herbivore eats the plant and gets its energy.then a carnivore or a human eats the herbivore and gets its energy. : )
