Yeah because of the muscle weighing more than the fat. What about the magnification one?

did they ask you to say which one was more healthy? i swear they just said to explain what male A's weight distribution was.
i talked about him not being obese due to like you said the muscle fat, and i talked about how i worked it out using the wasit:hip ratio. but i didnt say that B was more healthy. im scared now

You had to work out the magnification of the two lenses I think it was 3 marks and the total magnification was x400. That one?

I said that the leaves have chlorophyll, which makes it green because it needs to be photosynthesised, and the potato doesn't have chlorophyll because it isn't green. What did you put? Chlorophyll is a subcellular organelle right?

What did you put for the poppies and genetically modified yeast??

For that question I was confused whether they were asking me for talk about the stomota or normal plant cell. I wrote about normal plant cell because stomota is in paper 2 (I hope anyways)
