    Heyy can some1 please explain: (e) how C4 plants are adapted for high rates of carbon fixation at high temperatures in terms of: - high optimum temperatures for the enzymes involved - the spatial separation of initial carbon fixation from the light-dependent stage

    how did you paper 5 mehcanics go?!

    it was REAALLYYY BAD. I swear, the grade threshold should like come down to 2/50 for a C =O mine was THAT bad! and every1 at my centre found it very difficult also! Whyyyyy would CIE do something like this too us? :O: I didnt check what varient i got.

    M2 (paper 5)

    November 10 . 53 , Q4(ii) Friction force acts in direction of of the force at B BUT it is parallel to the plane (because friction is between the rod and the plane) so, resolve parallel to the plane. Fcos30 + Friction = 15cos60

    M2 (paper 5)

    For November 09 , 51, Q4 (ii) So you found the force to be 2 N in the first part right? now you use F = ma. so 2cos(theta) = 0.12 x (v^2/ r) (cuz a = v^2/r) therefore, 2 x (0.4/0.5) = 0.12 x (v^2/ 0.4) v = 2.31 ms^-1 the radius is 0.4 because a triangle is formed with...

    Chem P4 eelctrode potential help

    Look at the half equations for the electrodes. For the cathode, Increasing OH shifts equilibrium to the right, more electrons are produced, so E will be more negative For anode, Increasing OH shifts equilibrium to the left, again, more electrons are produced, so E will again, be more...
