3.Even though there are some dna traces in the mitochondria,it’s won’t really be tested for gcse and mostly the DNAs are found in the nucleus of the cell.
There are so many examples for that in different areas, like organic germanium compounds experiment carried out in our lab recently.
Here's one link: http://www.alfa-chemistry.com/products/organic-germanium-24.htm
They construct dams and create an ecosystem for other species . Because of their dam building nests become available for birds, fish population increases and waterfowl population goes up
The creation of DNA fragments with ends that can join with other DNA is achieved by the use of restrictive enzyme analysis.
<h3>What are restriction enzymes?</h3>
They are enzymes utilized in genetic engineering or gene recombination technology to cut DNA at some specific points in other to have sticky ends.
The sticky ends DNAs are able to join with other DNAs using these ends. Another enzyme (Ligase) is utilized to join the DNA back once the desired DNA has been inculcated.

For number 1 the first arrow is the cell wall, the second is the membrane, and the last arrow would be the cytoplasm
For number 2 they are in distilled water Bc they are remaining the same and not shrinking up
For three draw the cells smaller salt water sucks the water out of them
For four they get smaller because the salt has a higher concentration making the water leave the cell. Once water has left the cell begins to shrink
