    Ermm only a positive correlation, there may be other factors effecting the rate.
    woooo
    I hope this makes up for my crappy biol1 mark..

    But the athletes may have different levels of EPO to other people.
    Why would they have different levels of EPO? Even if they did it wouldn't be massively different, the question is only asking for you to say "take readings from a large number of healthy (no/few health issues) people and take an AVERAGE"

    cell wall/!?
    I don't think cell wall was labelled??

    I put chloroplasts and starch storage.

    for the first question i put flagellum and chlorplasts
    ooops sorry, thought you talked about a different Q but flagellum is wrong (sperm) you should have written chloroplasts and cell wall.

    For the maximising sunlight one did anyone else put that it moves to areas of higher levels of sunlight :')?

    Not flagellum, sperm cells have them...

    I put cell wall.

    And also, how did you guys interpret the light sensitive thing for the question after on adaption for maximum photosynthesis?
    i dunno
    for that question

    i wrote about a lot of chloroplasts - light
    then i wrote about the vacuole even though it didnt specifically have it on the diagram \: (vacuole pushes chloroplasts to the edge..)

    Exactly what i was thinking so i wrote procure blood samples from a group of athletes who had not previously used synthetic EPO...becuz surely athletes have generally higher levels of EPO if their profession is atheletics?!? XD :P

    I put that the chloroplast (I'm guessing that was one large chloroplast it was pointing to) was close to the edges of the cells, minimizing the diffusion distance for carbon dioxide and water required for photosynthesis.
    Also I put that the chloroplast contains its own ribosomes (those little black dots) which allow it to quickly synthesize proteins for photosynthesis.
    Finally I put the light detector thingy allows it to detect...light.... ...and so it can use its flagella to move into areas where there is more light.

    Friggin' frogs.
    I liked the frog question, it's the ****ing lymphatic system I forgot about and the minutes questions OH and that bloody starch one at the beginning. :facepalm2: Wat was I thinking tbh. Must have lost 20-30 marks on silly mistakes.

    cell wall was labelled.
    Also starch storage can be in the form of glyocgen in animals (animal starch)

    I put the light sensitive thing would be sensitive to light since that it would position itself as far away as possible so the chloroplast would face the maximum sunlight (they are on opposite sides of the organism).

    Hah, frogs are turning into the bane of my existance.
    They came up in the BIOL4 exam I sat this January too.

    I think it was to do with the piece of info in the question saying "Many people are already very ill when they get mrsa"

    I didnt write about the light detector thing
    But i wrote many chloroplasts - absorb light, also about the ribosomes.
    It was worth 3 marks \: not sure if i've got them all.

    For increased photosynthesis:

    -Flagellum, to move towards the sun light
    -Chloroplasts contain chlorphyll to absorb sunlight

    Yes, chloroplasts, then mention the light-seeing eye or whatever as more light=more photosyn, and use of the flagellum to move towards places of high light intensity.

    Light sensor thing to detect light.
    And a flagellum to travel to the light.

    I only wrote about many chloroplasts, a light sensor and the flagellum for that because it was only 3 marks. Hope it was enough tbh. I thought those tiny dots were the chloroplasts not the riobsomes????
