    Yes October had 4 readings higher than any other month, April was the month where people could not swim because the pollution level was considerably high as the disk disappeared early which means that the water was not clear and therefore polluted !!

    the disk didnt disappear in april!

    I put because they measured again in April and it was fine, any of the other months could have been too polluted it just depends on when they measured it

    what was the answer about heart attacks and why they occur when there is less oxygen in the body?

    Anaerobic respiration will take place in the heart muscles giving out Lactic Acid...hence causing a heart attack
    Hope I'm not wrong

    I wrote less anaerobic respiration as I remember but didn't worte much because it was 2 marks or 1 mark. Not sure which one I wrote next but probably no energy for cells and cells die I guess. It was a nervous moment Lactic acid didnt pop in my head damn
