Answer:
<h2>50%</h2>
Explanation:
As given;
A true breeding plant with purple flower: PP
A true breeding plant with white flower: pp
Cross between these parents = PP× pp
Offspring are =Pp, Pp, Pp, Pp( all are heterozygous purple)
Now cross between this plant and recessive white flower (pp)
Pp × pp
Offspring are: Pp, Pp, pp, pp
50% are white and 50 % are purple.

Answer:
A
Explanation:
In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches.
Bacteria in general grow optimally when the pH is around 7 (5-9 let's say). That is not to say that there are not bacteria that grow in extremely acidic conditions, like in our stomach, or others in extremely basic conditions, like the conditions near volcanoes. Nonetheless, bacteria that grow in food prefer acidic environments over basic ones and usually cannot tolerate the acidity of fruits which is around 4 pH for the most acid ones. For example, stuff like milk and bread that have a pH from 5-6 are prime examples of food where bacteria would thrive. Thus, the correct answer would be b.
