    i think its CO2 i put oxygen but it said in a closed system so i crossed it out

    ffs i wrote reabsorption too
    I thought glucose is removed by re-absorption in the first convoluted tubule?

    swear the question was about how it was reabsorbed into the blood? I put Selective reabsorption against the concentration gradient through the tubules?
    Same I think it was re absorbed into the blood, I put exactly that too.

    No, thats what i put but thats it reabsorbing into the blood, ultrafiltration is out of the blood

    Algae respire aerobically though

    did people get carbon dioxide for the growth of micro algae? because of photosynthesis? and 52.94% for the maths one? im annoyed because i talked about reabsorption instead of ultrafiltration for the 2 marker on glucose out of the blood
    I got carbon-dioxide and 52.94% as well. I also wrote about reabsorption rather than ultrafiltration. I can't remember what the question was.

    but plants dont grow from respiration, thats using up energy

    I really liked the paper! I'm so glad it wasn't too hard since I was at a gig last night so didn't get much sleep but I feel like it went really well!

    guys, i think we are right about the reabsorption because apparently it was "how is glucose removed from the nephron"

    I thought respiration always releases energy not uses and photosynthesis just makes the glucose?

    sorry i meant it releases energy, but it said how do the micro algae grow in a sealed environment

    I was sure that it was oxygen, but I can't remember the question now.

    I think they'll mark both right because a sealed container doesnt mean no oxygen

    It would need oxygen to produce energy for growth

    i was stuck on it for ages, it said " what gas would you supply to allow micro algae grow within a closed system"

    It says "supply" - You can still have oxygen in a closed environment

    Both may get the mark, as respiration releases energy as well.

    I changed my answer from 52.9 to 47 since 170 X 0.47 is 80 but I'm not sure if I changed it from the right answer to the wrong answer :-(
