AQA A2 Biology BIOL5 - 17th June 2015

Yeah buddy! Roll on children pretending not to smoke after parents!



You won't get marked down for not including any

for the essay would it affect my marks if I talked about keeping warm in cold conditions and describing the whole process and not describing reducing body temperature but just saying that an opposite process is involved?

you wouldn't lose marks, you just wouldn't gain any extra :-)

I put they might lie or another person in the household might smoke but they're not included.

wtf why has no one made a mark scheme yet?

my teacher said you can get a maximum of 21 marks if you don't go off spec, although tbh 21 is still a very nice mark

I wrote about that's as well!

wtf why has no one made a mark scheme yet?

I think your teacher might be telling porkies.

How can you possibly know something that is outside the syllabus us for every essay question?

Anyways, its over, im just happy all 14exams are done

I thought it was talking about calcium ions in the pre-sypaptic membrane? I must have misread it

The question was definitely about calcium ions in the presynaptic membrane

I wrote about:

Controlling population grown due to limited resources and human impact on global warmin.
Controlling human reproduction because of harmful genetic diseases
Controlling succession to conserve habitats and species and the benifits of this to humans
Controlling the growth and development of Bacteria due to the increase in antibiotic resistance
Controlling development of other mammals (hypothesised in a recently published journal that some mammals have the potential to develope and become as intelligent as humans, e.g apes and monkeys and why we should do this [human dominance])

how many topics do you need to include in your essay, i included 3 and went into detail is that even enough?

For the essay question 10a I wrote quite a lot on transpiration in plants and how light intensity (external environment) affects the rate at which they take up water etc. for photosynthesis & respiration (internal), and how they need to respond to different external environments to survive - have no idea if this would be credit worthy, looking back at it, but wanted a link to unit 2..What do you guys think?

I wrote about 5 topics including heart rate with co2 and pressure
water in plants and insects
glucose
temperature
and kinesis

however didn't mention both sides for each point due to it being similar and briefly mentioned them i.e. saying opposite would happen . Would this still allow me to achieve high marks for content?
