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:
A reflex arc is a nerve or neural pathway that controls a reflex action giving fast response to a stimulus without the conscious act of the brain. Here, the sensory neurons receive stimulation then synapses or connects to spinal motor neurons nerve cells which then connects to muscle cells acting as effectors.
Ranking the events that occur in the reflex arc in correct order gives
1st ---- A sensory receptor detects a stimulus
2nd---A sensory neuron conducts action potentials through the nerve to the spinal cord
3rd----- The sensory neuron synapses with an interneuron
4th----- The interneuron synapses with a motor neuron
5th------- The motor neuron conducts action potentials through the anterior root and spinal nerve to an effector organ.
