Explanation:
Tetrodotoxin is the molecules that act as a poison to the organism in which they are injected.
The tetrodotoxin proves lethal to the organisms as it kills the organism by interfering with the nervous system. The tetrodotoxin blocks the sodium channels in the neuron as a result of which the sodium is unable to enter the neurons and hence the electrical impulse is not generated.
If the tetrodotoxin blocks the motor neuron transmission by blocking the sodium channels then the signals will not reach the muscle and muscle will not be able to contract.

The primarily use of coal is mostly used for electricity generation, steel production, cement manufacturing, and as liquid fuel.
Advantages: it helps produce electricity, coal energy is affordable energy source because coal's stable price compared to other fuels sources, coal is easy to burn, coal produces high energy upon combustion, coal energy is inexpensive, coal is abundant, coal energy is a reliable energy source.
Disadvantages: coal energy produces large amount of carbon dioxide which leads to global warming and climate change, the burning of coal is not environmental friendly because it produces harmful byproducts and gas emission such as sulfur dioxide, carbon dioxide and nitrogen oxide that causes pollution to the environment including acid rain, coal energy is nonrenewable energy source, coal is fast depleting because we dont consume too much of it, coal mining ruins the environment and puts the lives or people especially the coal miners in danger. <span />
