The answer is 4. Cloning is when you make an exact copy of something. So they resemble each other because they have the same DNA.
Answer:
hypothesis is the answer maybe?

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.
This is basically weather, but its weather that stays over a long period of time.
Like the climate in the Sahara Desert is hot and dry. That is because its like that most of the time.
You could say Antarctica's climate it cold and snowy, because its like that most of the time...
Get the drift?
