    1)simplify as far as possible: x^-1/2+x^1/2 divided by x^1/2+x^3/2 2) solve the equation: (10/x^2+x-6)- (4/x^2-2x)-2/x^2+3x=2/5

    there is no point of arguing, it is graphite and arguing wont make ur answer right, everyone is very stubborn and so i dont think that i will convince or you will actually convince me, so leave the exam behind u and enjoy ur summer :)

    the answer is C 100% sure , lets say u have ethanoic acid do u say it has the fuctional group OH and COOH or you only say COOH???? i have no idea about what u said about alkenes :/ it is both and this was repeated in may/june 2010 ( i think) but instead of using homologous series he used class...

    just think abt it as if u know nothing abt chemistry, how can u plate something with diamond???? it is actually impossible but from a chemist point of view diamond doesnt conduct electricity. it doesnt slip when u coat something it stays on it just like painting when u paint a car, the paint...

    no you cant divide the COOH to OH and CO when it is COOH its an acid only not an alcohol so the answer is C (carboxylic acid and alkene) for the other one it is bothhttp://en.wikipedia.org/wiki/Enol

    P2Q Harder than copper doesnt conduct electricity at all but volatile for the homologous series one, it is either both (alkene and alcohol) or none. im not sure but i did it both

    BIO PPR 1 V1 <3

    this question was asked alot, the products of respiration are CARBON dioxide and WATER so the answer is carbon and water cycle

    ok

    BIO PPR 1 V1 <3

    i dont remember the question, but did it say they are aerobic bacteria?
  17. Abu mota

    BIO PPR 1 V1 <3

    it didnt say these places, it just says how they form groups, i think
  18. Abu mota

    BIO PPR 1 V1 <3

    but it is saying they form groups, it starts with one bacteria and reproduce to form alot of groups, why will they form groups to respire?
  19. Abu mota

    BIO PPR 1 V1 <3

    why?
  20. Abu mota

    BIO PPR 1 V1 <3

    for bacteria it is reproduction, photosynthesis makes absolutely no sense, ur asking about the question which how bacteria forms groups right?
