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.

Explanation:
the weak don't survive the strong thrive
Cations, lose
Explanation:
Positive ions are cations and they result when an atom lose electrons.
An atom is made up of subatomic particles:
- Protons are positively charged particle in the nucleus of the atom
- Neutrons carry no charges and they share the nucleus with protons.
- The electrons are negatively charged.
- When an atom loses an electron, it becomes a positive ion because the number of protons is now more than the number of electrons.
- An anion forms in a reverse way.
