Answer:
If the cell has not properly copied its chromosomes, an enzyme called cyclin dependent kinase, or CDK, will not activate the cyclin, and the cell cycle will not proceed to the next phase. The cell will undergo cell death.
Explanation:
The genes contained in the species' chromosomes would influence a species' physical appearance, would it not?
The alleles that species gains from both parents helps determine what that species physical appearance (also known as the phenotype) would look like.
Hope this explanation helped you. :)
Answer:
macroevolution
Explanation:
Macroevolution is said to be the evolutionary changes that occur on a larger scale beyond a single species as a result of evolutionary forces such as mutation, gene flow, genetic drift. Macroevolution, unlike microevolution, usually results into the emergence of two new species with pronounced changes. The event as illustrated in the question is an example of macroevolution.
