OCR biology paper 2 2019 discussion

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

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

Don’t they fuse by electricity?

Well I got 10,082 so yeah den

What did people get for the end question, (the fill in the blanks one)

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,

i remember i used carbon somewhere and can't remember the other words i put but it was a nice 6 mark fill in
also the last bit: cholesterol helps with stability and produces steroids + vitamins

was the atoms bit hydrogen?

what did people get for hardy weinberg? think i put B 22.7%

oh yeah i remember now cause unsaturated bonds means less hydrogens

Yeah I used carbon and hydrogen somewhere and then stability an vitamins. I think I said insoluble and storage too somewhere

I also said they were used for energy storage and I also said lipids were insoluble
