Why was the age not shown on the X axis
I said it’s hard to tell the exact age of a nucleus because it’s taken from a body cell and you don’t know when it was produced by mitosis something like that

For the amount of amino acids that would
Be different (MCQ) I said 0-1
I said the passaged described an ecosystem
I said the non competitive inhibitor was A
For the questions about dna purification
The onion was broken up to increase surface and to volume ratio so the enzymes could break down the dna faster
Protease enzyme breaks down peptide bonds between DNA
The pinaapplejuice may contain other enzymes the could disappear
The ethanol should be added drop wise
And it was a precipitation reaction ?

I wrote the development of embryo of mice and the other organism is at different rates so cannot he shown using the same scale

1192 for phospholipids, 6.25% percentage uncertainty, 10% woodland, 0.65 something for index, Higher amounts of LDL proteins in blood and tissues lowering density which allowed aquatic organisms to float on water, hydrolysis is the breaking of ester bonds through additions of water molecules,

Sorry I meant competitive inhibitor I couldn’t tell the difference between A and D so hopefullly I put D I can’t fully remember

Onion was broken in mortal and pestle to break down cell wall.
The step missed was adding detergent to distrust cell membrane
Protease enzyme break down histones protein associated with DNA forming chromatin
Contamination of DNA with pineapple dna
Precipitation reaction
Idk whose answers are correct but will appreciate other people telling their answers too

wrote all that but I said pineapple juice is slightly acidic and so could therefore damage DNA fragment
