Colchicine is the drug that prevents the assembly of the mitotic spindles which halts or stops the cell cycle.

This acts as checkpoint which can halt the cell cycle at the phase of chromosome condensation.
Thus, option-A is the correct answer.

Thus, the correct answer is option (2) and (3).
Producers <span>have the ability to make their own food using an energy source, like the sun. An example of this would be a plant.
</span>Consumers<span> are broken into two groups: primary and secondary.
</span>Primary consumers<span> are the herbivores that eat the producers.
</span>Secondary consumers<span> are the carnivores that eat the primary consumers.
Deer are herbivores and wolves are carnivores; they are both consumers.
</span>So the main difference between producers and consumer are that producers make their own food and consumers can't. They eat producers and other consumers.
