Answer: Botulinum toxin
Toxins are non-living
biological and chemical agents produced by living microorganisms from animals
and plants that can cause harm to humans, plants and animals. An example of
toxin is botulinum toxin produced by the bacterium Clostridium, which is a
neurotoxic protein that prevents the release of the neurotransmitter
acetylcholine from axon endings at the neuromuscular junction and causes
flaccid paralysis.
Moreover, toxin are more
closely related to chemical warfare agents that can only affect those who are
exposed to the agent and that they are not considered as transmissible disease.
Answer:
Genetic variation
Explanation:
Genetic variability (diversity) stems from two basic processes: mutation and recombination.
If there were no mutations, all genes would exist in only one form, they would not have alternative forms.
Since phenotypic variability also depends on genetic variability, it is clear that the processes of mutation and recombination contribute to the creation of a large number of different phenotypes.
