Cancer cells given vinblastine would be unable to separate chromosomes during cell division.
It is shown that the effect of vinblastin depends on its concentration, at very low concentrations it suppresses microtubule dynamics and at higher concentrations it reduces microtubule polymer mass.
Microtubules are part of the cell's apparatus for dividing and replicating itself, so inhibition of these structures results in halting the cell division and thus, cell death.

Answer:
First two rings are thicker while the last two rings are thinner.
Explanation:
Due to the first two years of optimal growing conditions received by the tree, the width of trunk of the tree is thicker but due to drought conditions experienced by the tree during the most recent two years, there is very little increase occur in the width of the trunk because the tree is in stress condition and for that reason the ring of trunk is thinner as compared to first two years.
I would say no because some times you could be cat fished and let’s say you were to go on a date with that person for the first time they could possibly hurt you or kidnap you
