AQA BIOL2~3rd June 2013~AS Biology (Now Closed) Watch
You're asking me to show you something that is implied rather than stated. Perhaps it would help if I expanded on the question under discussion.It is from an older ‘B’ Spec that was current in 2000 and only states the following in its section on tissue fluid:
“The relationship between blood, tissue fluid, lymph and plasma.”
There’s no mention of having to calculate pressure but it was perfectly in order to ask this in the actual paper. If your school has purchased Exampro, you can find the full question by applying the topic filter of “transport systems”
Similarly, the current specification refers to magnification and resolution but there’s no reference to calculation. In questions however,you can be asked to calculate magnification or object size. So experience tells us that some things are implied rather than stated.
What do we have to actually know about Meiosis?
My CGP book seems to go into a fair bit of detail compared to the Nelson Thornes one...
You will find one of the past papers asking for what it means.
It usually is asked in the haemaglobin questions....
In Unit 2, as well as DNA/meiosis, you see it in haemoglobin/transport and a bit on how orgs are related.
Like cytology, it’s a good example of one of those things you just carry with you through the whole A level.
same,dont exactly understand the dissociation curve either.I get that for human haemoglobin it shifts to the right and for organisms that live in a o2 depleted enviroment it shifts to the left;but why?How do i interpret this graph?
Same applies to effetc of co2,enviroment and activity level of organism
someone please shed some light on this thankyou!
