# AQA Biology B2 Exam watch

1. i was thinking that!then i wrote 1 then two
(Original post by Turtlebunny)
I got 23, and 46 because its for all the alleles in the entire cell.
2. 0.1mm (scale) = 4cm

4cm = 40mm

40/0.1 = 400

Anyone else get this for magnification?

God knows, it is over now though xD

What did use put for the magnification question its bugging me! I put 40 but wasn't sure to convert to (mm)
it was either 40 or 400
but im thinking 40

yass! chemistry next
i find it confusing
6. I am freaking out about this paper, b2? More like maths and random isa stuff! What did everyone get on the magnification question? Also 6 marker?

400, you had to convert 4cm to mm = 40mm and 40/0.1 is 400x Magnification.

The 6 mark completely threw me off...I ended uo talking about transect lines, I hope that's at least the direction they were aiming for.
8. Did anyone do foundation paper, how did you find it?

I put 40 because 40 times 0.1 equals 4 (the length)
The length was 4 cm... but the scale was in mm so 4cm on the diagram is 0.1mm, this means 400mm is 0.1mm - you have to convert it to mm first. Then 400 x 0.1 = 40 (the length in mm)
10. oh yeah i haven't heard from them someone in my class said it was easy

how many marks was that question??
13. For the magnification question:

0.1mm (scale) = 4cm

4cm = 40mm

40/0.1 = 400

Anyone else get this?
14. Magnification = measured size/actual size
This is the actual formula.

The measured size was 40mm, the actual size was 0.1mm.

So I think it was 40/0.1 = 400x magnification

I think was 2?
16. did anyone do B3???

I did, it was very nice

1 and 2. Only one dominant allele needed to express characteristic. Two recessive needed to express that characteristic. I think?

I was really happy with it but do you think the grade boundaries would be really high??

Alot of people I asked said homo , homo then hetro
Yep. You had to have heterozygous F1 (The first breeding) because later breeding resulted in white AND purple flowers.
To have ALL Heterozygous at F1, You had to have PP (For purple) and pp (For white.) The results could only have been either Pp or PP - Resulting in all purple flowers at F1.
