Neurons transmit signals to the central nervous system. The brain processes this information to initiate a response. Two neurons communicate with each other through the ( axon , dendrite, synapse) . The ( cerebrospinal cord, glial cell, neurotransmitter) is released at the site to initiate action potential and carry the signal through the body.
Answer:
synapse
neurotransmitter
Explanation:
Neurons are the basic units for the transmission of signals to the central nervous system. The two neurons are connected through the syanpse. Synapse is the space or junction between two nerve cells, or neurons.
The neuron receives signals through dendrites and two neurons communicate with each other through a chemical called neurotransmitter, which is released at the end of a nerve fibre and carry the signal through the body.
Hence, the correct answers are synapse and neurotransmitter.
Cyanobacteria, also known as blue-green algae, are found in vast quantities in fresh and salt water. Cyanobacteria are able to conduct photosynthesis. By utilising energy from the sun, they produce carbohydrates from water and carbon dioxide. As a byproduct, they produce oxygen. So cyanobacteria provided oxygen to the atmosphere that allowed other lifeforms to develop.
