Hello, if you put X10 -3 , would that be correct? (Malaria Question)

For the mosquitos, could you said a advantage would be that less people will have malaria as the males won't pass it on but then a disadvantage would be that there would be a drop in population as they there will be fewer adults to produce eggs?

What was that Independent company question and why is it important?

I put they are a separate company from the drug company who could offer unbiased results/opinions.

Let me know what you put!

AQA messed us up, previous B1 papers were so much easier than that. Grade boundaries better be low...

I had 10 seconds at the end so I randomly wrote that Lichens detect moisture and that you can use a 'moisture indicator' to detect it...

well I said that seagulls detect sea because sea is in its name. isnt that right? I am hoping for a A*

No. On two reasons: First off it was 2/3*10^-2 not -3 partway through the calculation. But 2/3*10^-2 is only halfway, because then you have to * by 100 to turn it into a %.

However depending on the first part of your answer you may get 1 mark.

Same. I'm reassured.

I very sure it is 0.6666666666..... Almost all people in my school got this answer and a lot have A* further maths so i am inclined to agree with them.

The paper was easier its just there was more worded opinion based questions which were new but they were common sense. I didn't finish the paper though :/

This is an early unofficial mark scheme! We finished the paper less than 50 minutes ago!

They did not have a single question, or even the slight allusion to:
- Menstrual Cycle
- Hormones
- Cloning - neither plant nor animals
- Pathogens/Disease/White Blood Cells
- Homeostasis

This is nearly, or it might be, half the specification!

Yup I basically put that up

@Puddles the Monkey I haven't got my my computer up and I'm just using the TSR mobile site. I'll try and put up as many answers as possible very soon.
