AQA AS Biology 7401/1 and 7401/2 Exam - 26th May and 7th June 2016

I think you did what I did and measured the radius instead of the diameter

Nah blud everything i revised never popped up

Nah I done diameter. But either way whether you do diameter or radius you should get the same answer. But it was how many times bigger e.g 10 is 2x bigger than 5. So is 20 2x bigger than 10

How did you get that? I swear you measure both the sizes and then divide the bigger by the smaller. I got 1.7x. Plus by looking at it it didnt look 3x bigger

What was the haemoglobin one? For water potential I put sea water contains salt - Lower water potential - water moves into worm down water potential grad via osmosis , worm swells , may burst , death

It was a circle, and said how times bigger is the area of D (or something) than B. So you do ( can't remember the values exactly)
Pi x r^2 as a ratio between the 2 (D and B)

Pi x 1.1^2 : pi x 0.65^2
3.8 : 1.33
Get the right had side down to one
2.9 :1
So it was X2.9 bigger
I hope so anyway lol

the vast majority of topics came up

the vast majority of topics came up

What did everyone out for the phosphate and embryo question??

Do you remember the measurement of D and B?

Do you remember the measurement of D and B?

i said hydrolysis of phosphate releases energy etc which is used in reactions but im dumb so that's most likely wrong

Wouldn't water move out of the worm? Because water moves from higher water potential in worm to lower water potential in sea water?

Damnn. You guys went in doing the area of a circle and everything. But I remember quit well D wasnt 3x bigger than the size of B

Do you think they will accept 2.9 (2 significant figures)
