Answer: Synapse connects neurons and neurotransmitters are the chemicals that help in the communication of neurons.
The given statements can be completed as-
The synapse connects the axon of one neuron with the dendrite of another neuron to relay messages.
The cells release chemicals known as neurotransmitters ( such as acetylcholine) into the synaptic gaps to communicate with one another.
Neurotransmitter are the chemical messengers that carry chemical signal to the target neuron where it gets converted into electrical impulses. Synapse is a place or gap between the axon terminal of one neuron and the dendrite of another neuron.
<span>A single tree absorbs tons of carbon dioxide in its 30-year life cycle and it releases a ton of oxygen. The free nitrogen from the atmosphere is captured by the nitrogen-fixing bacteria and it converts nitrogen into nitrates and nitrites which is then absorbed by the plants. Trees, like all organisms, grow by adding mass (biomass). Carbon is the central ingredient in making that new biomass. Tree biomass is comprised of all parts of the tree; leaves, stems, branches, roots, tree trunks. The biomass of the woody tissue in the tree pictured on the right is made mostly of cellulose, a carbon compound. In a process called carbon fixation, plants transform CO2, an inorganic carbon compound into organic carbon compounds.</span>
