T. it is described by what the Earth is made of and where it is placed.
The ocean moderates the Earth's climate. Most solar radiation occurs at the Equator, whereas the poles receive little radiation. The ocean<span> transport warm water from the Equator toward the poles and cold water from the poles back to the Equator. The oceans provide a habitat for much of the marine life exploited by humans, such as harvested fish. The oceans act as a massive carbon sink, as phytoplankton absorb carbon from the atmosphere through photosynthesis. The ocean also provides a medium for large scale transportation of goods through shipping. It is unlikely that vehicles as large as container ships could ever be transported over land.</span>
Explanation:
On island A,
Parrots with Dd were released therefore these will mate with each other and will produce:
Dd x Dd
D d
D <em>DD Dd</em>
d <em>Dd dd</em>
Therefore, 25% DD, 50% Dd and 25% dd genotype parrot offspings will be produced.
On island B, parrots with DD and dd were released, therefore they will mate and will produce,
DD x dd
1. D D
d <em> Dd Dd</em>
d <em>Dd Dd</em>
2. DD x DD
D D
D <em>DD DD</em>
D <em>DD DD</em>
3. dd x dd
d d
d <em> dd dd</em>
d <em> dd dd</em>
This shows that there is a possibility on island A where 25% DD, 50% Dd and 25% dd genotype parrot offsprings will be produced whereas on island B, chances are almost equal as all three genotype parrot offsprings can be produced but the percentage could vary.
