This is true, this happens because those with favorable traits are able to go on and reproduce while the weak ones die off and cannot reproduce. The resulting off spring will carry more favorable traits and the cycle continues until either the animal conqours the environment and becomes the apex predator (humans) or the species die off (dinosaurs)
Answer:
As a control, which, in this case, is a negative control. Since there is no carbohydrate added there will be no bacterial growth. In your tubes which do have some carbohydrate there will be bacterial growth. Since you used a control you can compare any changes in the tubes in which you have growth to the tubes without growth, which would represent the original state of the media. This makes any results easier to notice and interpret rather than having to remember what the tubes used to look like.
It also ensures that any change in the media is due to the growth of the bacteria and not some external factor. Since both sets of tubes were inoculated but only one set shows some change you can be sure that that change is due to the growth of the bacteria.

When a phase in the cell cycle does something incorrectly, mutation occur which leads to cell death or cancer.
<h3>What happens when a phase in the cell cycle does something incorrectly?</h3>
When a phase in the cell cycle does something incorrectly, then they cannot move to opposite poles in the later phases of mitosis, which result the cell with extra chromosomes and a daughter cell with missing chromosomes. These mutations can lead cell death, disease or cancer.
So we can conclude that When a phase in the cell cycle does something incorrectly, mutation occur which leads to cell death or cancer.
