    For A, 20 animals were affected, for B it was 14, and for C it was 2... Surely the answer is A?

    But surely the bin is a reward, so if the raccoon learns to push the bin lid off it is rewarded? Raccoons go through multiple bins each day, so they're repeatedly presented with a bin and they've learnt that if they interact with the bin, they're rewarded?

    I was 50/50 on putting operant vs insight but put operant because they phrased it as "the raccoon learns to push the bin lid off"
    I put insight learning

    The racoom had to think how it could open the tin and stuff

    That was my reasoning exactly, more individuals were effected in the A species so it had to be that one

    It was insight learning and not operant conditioning, OC is learning by reward and punishment whereas insight learning is using reasoning and judgement from past experiences
    wasn't the reward the food in the container?

    I put operant conditioning for the raccoon one because it didn't mention past experiences. Like the rats in the box to get a treat, if they just happen to take the lid off the bin then they get a reward?!!

    I put speciation for the snails near the road. I originally put geographical separation but then thought that was too obvious

    For the asthma one, it mentioned something in the question about that the drug binds to the protein receptors. So I said that children with the mutation may have different shaped receptors so the normal drug wouldn't bind...

    I'm on a gap year too and decided to retake this paper to boost my over A-Level score. I personally found that paper better than last year's but I found this year's F214 quite hard. Chin up everyone - no more Biology!!!

    I wasn't electrophoresis it was about fluorescent markers creating different wavelengths as the sequence is stopped meaning there is variation in size
    Omg this is what i put but everyone's going on about electropherosis and i keep kicking myself 😖

    Im not sure fam

    More may have been affected, but the frequency doesnt change much

    It has to be c. Small populations ---> greater chance of genetic drift and alleles being eliminated from the population. You could see this from the data in the table

    But you had to look at the allele frequency?

    I said both use a transport medium and both bind to receptors on the cell surface membrane
    Thats whats i put.

    Yeah either one increased and the other decreased (the allele frequency) I think it was by 0.20

    You had to go by percentage of allele frequencies, not the number affected i believe.

    It was only the biggest decrease because there were so few of them
