The Endosymbiotic theory was found in the Mitochondria as well as the Cloroplasts.
When taking a tissue culture for thoes who have cancer it allowes for more of a trial error method. When a tissue culture is collected the scientist/doctors get to test procedures on it to see what teatment works best for you. With out them there would be many people taking medicins that dont even help them with their condition; and in few cases could make it worse. Just saying tissue culturs' are a huge advancement in technology, and science.

Explanation:
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.
Living organisms modify their environment a little at a time
As an ecosystem progresses, the organisms in that ecosystem change their environment to best meet their needs, but they only do it in small ways which can make big changes over time.
