Answer:
Colchicine inhibits the formation of microtubules by inhibiting tubulin, a protein required for microtubule synthesis. Microtubules in the form of spindle fibers during cell division pull the DNA from the center of the mother cell into the new daughter cells. If microtubules are not formed DNA will not move into new cells. Hence new cell formation will be inhibited in the metaphase stage. Thus the correct answer is option D.
Explanation:
I do not know how the phylogeny chart you have is, but it probably contains a series of apes, gorillas and Homo sapiens.
We know that gorilas don't walk upright, but Homo sapiens do. What you will probably have to do is situate the new species of ape somewhere in between gorilas and humans, in a way that the new species shares a common evolutive path with both.

An omnivore eats both plants and animals!
Badgers, pandas, raccoons, and dogs are examples of omnivores I think!
The level of protein X in these patients will be low due to degradation in the proteasome. Ubiquitnation process occur when ubiquitin is attached to a particular protein and the protein become deactivated. Ubiquitin is a small biochemical molecule which marks out proteins for destruction. Any protein that have ubiquitin attached to it will be transported to the proteasome for destruction by degradation.
