    A biogas generator is like a system where biogas is produced..?

    And biogas is produced when animal material and plant material is decomposed by bacteria in anaerobic conditions making methane which can then be used as a fuel.
    And, explain how the kidney produces urine.
    Hmmm, how do they produce urine:confused:

    :O That's amazing. I think I'll just do that too
    I KNOW!!!
    And yeah, it is the best approach for me because the books do not have my own interpretations, which I hate

    Feel the same with French, would be happy with a C
    I thought I would get C/D at the beginning of the year, but I think I can aim for a B now. Just need to get above 25/40 in both the listening and reading and I've got a B I think, but to be safe I'll aim for around 30/40 in both because the grade boundaries can change a bit.

    awh you're kind

    I am not really sure, I am just finding it harder than unit 1+2 and the topics just seem way more complicated! I'll take you up on that offer in a couple of weeks when I have finished revising the bulk of it

    On school nights I aim for around 2 hours at home (I stay after school for a revision session for an hour most days). When it's a non-school day I aim for at least 4 hours.

    When I revise science I copy notes out from revision guide, summarise in a paragraph, do past papers and watch MyGcseScience videos. This worked for the unit 2 exams (got A*,A*,A) but now i'm very worried because I have so many other subjects

    Trust me, I thought that at first, but all you really have to do is actually apply yourself and do the revision. It won't take long if you're dedicated. Also, BE POSITIVE!!

    I will. De-oxygenated blood enters via the vena cava into the right atrium. The right atrium just contracts forcing blood into the right ventricle. The right ventricle then contracts forcing this de-oxygenated blood to go along the pulmonary artery and to the lungs, to get oxygenated. The oxygenated blood then returns along the pulmonary vein to the left atrium. The left atrium contracts forcing this oxygenated blood into the left ventricle, the left ventricle contracts forcing blood out of the heart along the big artery the aorta to the rest of the body.

    Hope it helps.

    Why do we need ventricles though? why not just go from atrium to pulmonary artery or whatever?
