Answer:
The correct answer is option C. "The magnetic field of earth keeps changing because of the suns activity"
Explanation:
The magnetic field of Earth is not a steady force, and is affected by external forces such as the suns activity, particularly during strong solar/geomagnetic storms. The changes in the magnetic field of Earth explains why the auroras Are sometimes seen at northern Ohio. The auroras are created by energetic electrically charged particles accelerating along the magnetic field, if the location of the magnetic filed changes, the location of the auroras change as well.
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.
