    BIOLOGY PRACTICAL P34???? 26TH MAY

    it was serial dilution so the concentrations of X must be 0.3,0.03,0.003,0.0003 by taking 1cm3 of each dilution and adding 9 cm3 water. Your table is correct i think adding extra should not be wrong.

    what? that water and X together made a concentration of X of so we didn't had to write that. did you did the dilutions right? 1 cm3 of X then 9cm3 of water and continue like this?

    BIOLOGY PRACTICAL P34???? 26TH MAY

    i think yes question one was too long.... i did question 1 first, then completed the 2nd in around 40 minutes and gave 20 minutes to question one again for its last parts.

    did you saw the pictures i attached previously in this thread? after you see them its clear that T was the correct option. But maybe, there is a chance that both can be right. the point is that we are only going to loose 1 mark for choosing the wrong one... and then ecf for making the plan...

    i wrote about the difficulty in counting point as well.... the variable we had to standardize was the concentration of X so it no longer effects the results and now another variable (next question e.g temp.) would effect the enzyme rate

    i am not sure about the froth one as there is no way to fix that error and it must happen and is part of the experiment so i don't think it can be an error but the bubbles one is definitely correct . I am not the marking scheme so do not trust me :P

    ratio i can't tell but it looks ok... as long as you used the method that every one used. for the "significant" errors i am not sure if i wrote right but here's what i wrote for part one of it i wrote that it takes time to put bung and then put the tube in water. and for 2nd part i wrote that...

    BIOLOGY PRACTICAL P34???? 26TH MAY

    that means you also did the part one of the writing questions wrong too? in which we had to mention inhibitors... if you are only talking about results in table then you will loose 3 marks which were for the results and will get 2 marks for drawing table and headings if correct.

    Yes thats right. All we can do is pray now :)

    BIOLOGY PRACTICAL P34???? 26TH MAY

    Bro are you sure you looked at "T" the bottom right image? it was exactly like the images i just attached . and the images i attached are arteries. T was "exact" copy of my first image placed horizontally. Think about it. All the others as i remember, had smooth inner walls which ends the point...

    maybe.. but you won't loose all the marks for the question, if your method to find ratio after wrong means was correct. the purpose of mean is that you take it from all around with all lines intersecting at one point (for diameter).
