Answer:
To reduce systematic error.
Explanation:
The researchers would have used random allocation in order to decreases systematic error in the experiment. If we don't apply random allocation to the experiment, there is high chances of systematic error in the experiment and the result is not of high quality. Independent variables is a type of variable whose variation does not depend on another factor while on the other hand, dependent variables is a type of variable whose variation depend on another factor.
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.

<span>The answer is eosinophils, when a muscle tissue in a human body is infected by parasitic worms, the white blood cell in charge of fighting the worms is eosinophils, Which is responsible for preventing the body from suffering an adverse chemical reaction by attacking itself to kill the parasitic worms</span>
