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.
Seedless nonvascular plants reproduce asexually through fragmentation. The parent organism are divided in fragments and these fragments or pieces grow into fully developed organisms. Plants like liverworts and lichens reproduce through this method.
The answer is the first E. Hope this helps! :D
