Antoni van Leeuwenhoek and Robert Hooke first discovered the presence of the microorganisms in the environment during 1665-1683. Using the microscopes, the discovered that there are many tiny life forms that are not visible to the naked eye. This discovery led to the shattering of the belief that the life forms can appear out of the ruined non-livings forms, and gave rise to the cell theory.

The cell theory states that the cells are the basic unit of the life, and every living organism is composed of these cell(unicellular) or cells(multicellular). The new cells arise from the already existing cells.

Hence, the answer is cell theory.

torisob [31]

Answer:

True

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.

Thus, true is correct.

Answer:

sour, corrosive

Explanation:

An acid is a substance that donates hydrogen ions. Because of this, in an acidic solution  there are more hydrogen ions than hydroxide ions. This means the more acidic a food is, the more hydrogen ions are available to trigger the sour taste receptors. A base is a substance that accepts hydrogen ions.
