Answer:
Number of bacteria required 
Explanation:
Given -
Size of each bacterium 
micrometers long
These bacteria are arranged end to end.
The size of chain to be formed is equal to 
centimetres
Let us say that in forming a chain of centimetres nearly X number of individual bacterium are required.
hence, number of bacterium required to form centimetres chain can be represented as
Number of bacteria required
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.
What are the species that are labeled a to e?
The statement is true.
Carbohydrates are broken down in order to obtain glucose for respiration in cells. When there is an inadequate amount of carbohydrates, other macromolecules must be broken down. Excessive breakdown of fats is not possible due to the fact that it causes ketosis; therefore, proteins are broken down and the body starts to lose muscle mass.
The goal of a cladogram is to show relationships and evolutionary descent between species.
