Answer:
In the given case, the flowers A and B are temporally reproductively isolated from each other.
Explanation:
Reproductive isolation takes place when populations cannot mate efficiently with each other. As a consequence, slight genetic differences originate within the populations. With time, the genetic differences gathered in the isolated populations results in the formation of various kinds of different species. In the given case, even though both the flowers A and B are the similar species, the two different flowers bloom at distinct times, resulting in a time-imposed or temporal barrier to reproduction.

Answer:
Explanation:
A Pure bacterial culture must be grown in sterile tryptophan or peptone broth for 24–48 hours before performing the test. A sterile environment helps to avoid contamination.
When a test is conducted and it shows the presence of a red or red-violet color in the surface alcohol layer it means the result is positive
But when the colour is yellow it indicate negative reaction due to glucose fermentation.
A deviation from two color may also occur when we have an orange color. This colour change is due to the presence of methyl indole
When there is no color change this indicate No decarboxylase which is an enzyme needed for the fermentation reaction.
Color changes are indicator of how successful the reaction was.
