AQA IGCSE Biology - 12th May

Well I guess that could be right but it's very ambiguous. I said that since battery chickens are stored in cages, more can be fitted in a given area as opposed to free range chickens which need a large space to move around in. As a result, the rate of production of food is higher for battery chickens.

Incorrect I'm afraid. The fan would increase the rate of evaporation off the leaf's surface so more water would be drawn into the plant. When all the water had been used, the cells in the leaf of the plant will become plasmolysed and the leaf will shrivel as a result.

The question asked about changes to the leaf, not to the plant so I'm afraid your answer would not gain any marks :/

Did anyone do Paper 1 today? How did you find it?

What was the answer on the malaria question? Thanks.

That is similar to what i put.
However, it is to do with how efficient they are individually, not how many they can produce as a whole; therefore the answer is that they conserve more energy to be used to lay eggs as a result they will lay eggs more frequently.

I didn't just write "The leaves would wilt"...
It was three or four marks
I wrote something along the lines of "The fan would increase the rate of transpiration which would mean that eventually the water would run out in the potometer. After this had happened, the plants would wilt; reducing the surface area of the plant so that less water would be lost"
Leaves are the bit that wilt, and there is nothing in the spec regarding the word "plasmolyse" meaning that although it may be a great term to use, I didn't need to mention it as our knowledge only has to stretch as far as knowing that the plant wilts.
I think that probably covered at least 2/3 or 3/4 so I will get the marks, even if it isn't all of them.
A test isn't just one question, either. The most marks I've lost is 3% if I didn't get any of the marks from that question. If I'm honest I couldn't care less because there is nothing I can do about it now.

Haha relax dude. If you didn't care why would you write such a long response XD.

Plasmolyse is a term used in the AQA IGCSE Biology text book so they'd expect you to know it. Having said that however, most past papers grant marks without the use of specific terms so you could get some marks for your answer.

And with biology a lot of marks are lost due to lack of detail. For example, I highly doubt you got all six marks on the pathogen question or if you got the multiple questions about structure and bonding correct.

3% is a bit over ambitious. Try and keep things realistic so you're not surprised or devastated on results day.

How do you think a plant wilts? In these sorts of questions, they expect development and plasmolysis is what causes the plant to wilt as a result of a lack of water. This links it directly to the situation they described with the experiment so will grant full marks.

So no, it isn't wrong.

Ok i got it wrong then i put 5, 4 and 0.4

For no 2 i multiplied 5 by 0.8 as that was the width of tube

then for no 3 i divided by 10 to get 1 minute so RIP me :|

i think thats right

Cancer
Enzymes
Breathing/HR/Exercise
Transplants
Digestion
Nervous System
Kidneys/Dialysis/4.6.2-4.6.4 from spec
Photosynthesis/All topic 6 from spec
8.2/8.3 from spec
9/10/11 sections from spec

how did paper 2 go for yall?

I found it pretty hard tbh I was so pushed for time and some of the questions were just so annoying like I wasnt sure what I should have written for some things and there were so many long questions!! I wanted more short nice answers ugh praying for low grade boundaries... I found paper 1 so much easier!! Wbu?

Yeah I know right! I thought that they usually only have 1 6 marker, but they had two and like 3 5 markers :O yeah I agree paper 1 was so much better

I'm not sure what was harder... The exam or other people who did the aqa igcse!!

The amount of 4/5/6 mark questions was ridiculous and I'd be lucky if I get a B

I think there was 3 actually: dogs, the catalase one and the design an experiment thing :/// and then the 5 markers weren't fun either oh well hopefully won't have been as bad as I thought! I had no time to check anything and usually have 10-20 minutes! Was the heart rate recovery question about repaying the oxygen debt because I had no idea? Cry
