Answer:
"In the 1960's, the purple sea star was one of the first species recognized as a keystone. Its presence keeps tide pools in balance and prevents mussels from taking over the ecosystem."Explanation:
The answer is 1 red radish, 2 purple radishes, and 1 white radish
Let R allele be dominant allele over r allele. The genotypes and phenotypes will be as following:
RR - red radish
rr - white radish
Rr - purple radish
Parental generation: RR x rr
F1 generation: Rr Rr Rr Rr
Since the F1 generation self-pollinates, we have the situation:
F1 generation: Rr x Rr
F2 generation: RR Rr Rr rr
Punnet square:
<u> Rr </u>
<u>R </u><span><u>| r</u>
<u>R </u></span><u>| RR | Rr</u><span>
Rr <u>r </u></span><u>| Rr </u><span><u>| rr</u>
So, there will be 1 red radish (RR), 2 purple radishes (Rr), and 1 white radish (rr)</span>
Carbon can be found in phytoplankton and can be disolved and stays in the form of gas in the ocean.
