Answer;
Endocytosis process
The vesicular process involved in the toxin entering the neuron is endocytosis process.
Explanation;
Endocytosis is a vesicular process, that involves capturing a particle or a substance from the outside of a cell by engulfing it with the cell membrane, and bringing it into the cell.
Botulinum toxin binds to the neuronal cell membranes at the nerve terminus and enters the neuron by endocytosis.
The chemical group is the methyl group (-CH3).
The enzyme that catalyzes the elongation of DNA is called DNA polymerase. DNA polymerase synthesizes DNA molecules from deoxyribonucleotides which are the building blocks of DNA. This enzyme is very important to DNA elongation and it works by creating two pairs of identical DNA strands from from a single strand of the parent DNA.
I think the answer is number 1
I Think That It Is B Because it divides repeatedly to produce many different cells
