Answer:
A control group setup in an experiment is used to see if there are other variables in play during the experiment. Say I was to test which type of blood is a shark's favorite, my control would be putting red paint in one of the set ups to see if the shark is just interested in the red color of blood, instead of the other types of blood.

Hope this help
plz mark brainliest
have a nice day!!!!!
Not judging, but you probably would've gotten the answer if you posted in the Chemistry subject.
Answer:
C would be the incorrect statement.
Explanation:
When doing the calculations for finding the neutrons, you would get around 24 neutrons, since the mass is about 45 amu. 21 would be the number of protons.
Hope this helps :)
Answer:
The correct answer is - acidic conditions wouldn't trigger a change in the color of Alizarin yellow.
Explanation:
The growth of E. coli generally occurs at neutral pH, however, its growth is normal at acidic conditions as well. The change in the growth of E. coli is not able to detect by alizarin.
The phenol red turns yellow in the presence of an acid, and the change in pH in an alkaline environment can be detected by the red color of phenol red. Growth of E.coli will grow in pH of 10-12 . But, very slowly. The color change in alizarin is also apparent at pH 10.2 to 12 only.
