Answer and Explanation:
The dendrite connects the axon of one neuron with the dendrite of another neuron to relay messages. Neurons transmit information to each other throught synaptic gaps. The cells release chemicals known as neurotransmitters to communicate with one another.
A synapse functions to allow transmission of nerve impulse from neurone to neurone. Acetylcholine is a substance that is used in impulse transmission. When an impulse reaches the synaptic knob, it stimulates the vesicles to move towards the pre-synaptic membrane releasing acetylcholine. The transmitter substance makes the membrane permeable.
Burning fossil fuels or cement has relatively little of an influence on humans in terms of producing carbon dioxide. The general people has been duped into believing we are a major factor in the greenhouse effect.
The biggest misconception regarding the movement for people to emit no net amount of CO2 is that natural supplies of this plant nourishment dwarf our emissions. This indicates that even if all people disappeared overnight, atmospheric CO2 levels would not significantly drop.
The statistics on the steady increase in CO2 throughout the heaviest periods of the global lockdown, which significantly restricted any human-sourced emissions, will give you a decent idea of this.
As for the so-called greenhouse gases, CO2 naturally occurs in water vapor, which makes up more than three times as much of the GHG as CO2. This indicates that the human component of the GHG is 0.6 percent.
When you take into account how little human emissions are in the grand scheme of things, you have to stop and wonder if any efforts you make to lower your emissions are in vain.

Answer:
B. Cells in Alex’s body underwent mitosis to create new tissue
Explanation:
Mitosis is the cell division that forms two genetically identical daughter cells from one parent cell. It occurs in somatic cells and is responsible for the growth and development of individuals.
Alex gained the height as the cells in tissues of his body underwent the mitosis and produced new daughter cells. Repeated cycles of mitosis added a large number of new cells to his body to form new tissues in his body parts and caused an increase in his height.
Answer:
hydro energy and gravitational energy
Explanation:
Myelin is a lipid-made substance that surrounds the axons of some neurons. This myelin sheath acts as an electrical insulator and speeds up the propagation of the action potentials inside the neurons' axons.
