Answer:
Botulism toxin disrupts motor control <u>by blocking the release of acetylcholine by motor neurons. </u>
Explanation:
Acetylcholine is the principal neurotransmitter in motor neurons. If there is no release of acetylcholine from the presynaptic motor neuron, the ion channels will not open. If the ion channels do not open, Na+ cannot enter the postsynaptic membrane to start an action potential. As a result, the muscle can not move.
The ion channels have a specif receptor for acetylcholine. When acetylcholine binds to the receptors, the channels open. With the ion channels open, Na+ can enter the postsynaptic membrane to start an action potential. This does not happen in the presence of botulism toxin since it blocks the release of acetylcholine.

the same as an increase in latitude
Explanation:
An increase in latitude produces the same effect on climate as an increase in altitude.
- Altitude is the height of place above or below the sea level. An increase in altitude leads to a decrease in temperature. The higher one goes up, the cooler it becomes.
- Latitude is the distance north or south away from the equator.
- As one goes away from the equator, temperature decreases.
- The poles are the coldest and they have the highest latitude.

Answer: Option 'C' is correct.
Explanation:
Radioactive forcing increases means the earth will get more energy from sunlight than it radiates to space.
It eventually leads to warming.
So, average temperature would increase in that particular area.
Hence, Option 'C' is correct.
