--- Quote from: sanity_master on May 15, 2009, 08:32:55 pm ---like temperature and time taken for starch break down for example;
the time taken depends on the temperature.......as temp increase time decrease......
u know wt i mean......the time will change when the temp change not the opposite.....so the time taken is dependent and the temp is independent

okay.but my teacher said usually we put time taken in x-axis.is it right?
--- End quote ---
thats the " time " wt i said was the " time taken ".......
the first one is like the volume vs time >> here the time in independent so it is on the x-axis.......because the volume of a certain gas (for e.g) will increase as time passes
but the second one.......the time taken for starch to be broken down by enzymes will depend on the temp......as the temp increase the starch will be broken down in less time
SGVaibhav:
is this right?
if the marks for a curve were out of 1, do u think will i get the one?
and check the other things and tell me if it is right or not?
and if anything is wrong, plz tell me what is wrong, or scan the answer
thank

2004 may june biology 0610 IGCSE CIE Question 3 Part (b) (ii) [lol]
SGVaibhav:
sorry the size is pretty big of the scan
a doubt
they have mentioned like this in the markscheme..
O orientation of axes;
A both axes labelled + units;
S even scale;
P plotted correctly;
L line of best fit or ruled line point to point;
WHY NOT A CURVE? :@:@:@::@:@:@:

Its what the biology examiners prefer...my teacher went to some cambridge conference and they told her there so its better to have a ruled line as its more accurate than a retrded curve :P
SGVaibhav:
the error made my straight lines is more than human error
our curves cause less errors
