Answer:
Neurons communicate with each other by synapses
Explanation:
Neurons send signals to other neurons through synapses. The most common type is chemical synapse; a chemical synapse occurs between the axon terminal of the neuron that sends the message and the dendrite of the neuron that receives the message. The first one is known as the presynaptic cell and the last one is known as the postsynaptic cell. Moreover, in a chemical synapse, the presynaptic and postsynaptic cells don’t touch each other as they are separated by a very tiny gap known as a synaptic cleft. The chemical synapse transforms an electrical signal (which is the action potential in the presynaptic cell’s axon) into a chemical signal (which is the neurotransmitter) and back to an electrical signal (the postsynaptic potential) in the postsynaptic cell.

Answer:
mitochondria, golgi, ER
Explanation:
These folds have a great advantage for mitochondria as they increase the surface area where chemical reactions occur.
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. The gravitational pull of the sun and moon on the earth also causes waves.
