Answer:
Botulinum is a toxin that can be used to cure wrinkles in human beings by injecting it in very small concentrations and it works in preventing the signals from the nerve cells to muscles and thus paralyzing them by stopping wrinkle formation.
Wrinkles are caused by the contraction of muscles and this neurotransmitter does not allows the muscles to contract. In order to contract nerves release a chemical messenger called as acetycholine. This neurotransmitter is found at the junction where the nerve cell reaches the muscle cell. This causes contraction of muscles.
Injecting botulinum prevents the release of acetylcholine which prevents the contraction of muscle, causing reduction in wrinkles and muscles become stiff.

The acceleration would be the velocity at point O divided by the time of point O, also known as the slope at point O. (y/x)
During mitosis division, each chromosome is duplicated, and then the cells are divided in half. Because there are two copies of the chromosome, the two resulting cells have the same number of chromosomes compared to the first cell.
