u can use con doms to stop it.
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.

Question 17) An unstable ratio of protons and neutrons
Question 18) A homgenous solution
Question 19) An element
Question 20) Freezing
Question 21) The number of protons in an atom.
Question 22) have a full outer shell of electrons.
Question 23) Non-metals
Answer:
A. Destruction of terrestrial biota
Explanation:
all the other answers would decrease the carbon output. thickening of ocean sediments reinforces a carbon reservoir (which stores carbon), reduction in the use of fossil fuels would reduce the amount of carbon emissions, increase in marine biota = increase in carbon storage because marine biota is also a carbon reservoir.
Destruction of terrestrial biota would cause excess output because terrestrial biota is a carbon reservoir, and all of that carbon would be released into the carbon cycle.
