    Yes. Golgi and Smooth ER does actually look quite similar. But there are a few tips with which you can easily distinguish them. 1) Golgi produces lysosomes or vesicles. Youll see these circular vesicles around the golgi or maybe even pinching off from it or fusing into it. There would not be...

    Writing precipitate instead of PPT would only take an extra 9 milliseconds. It's better if you write the full word, because the examiner often needs just an excuse to deduct your marks, and you should never give him any.

    Hello there. When we make a graph in our P5, there is always a question about calculating the Gradient. When we calculate the gradient we have to show the 'Gradient-Triangle' which has its own marks. The question is, when calculating uncertainty in gradient we subtract the gradient of Best...

    Question 7 (iii) 70 days at random, how many would have temperature more than 3 times the mean. So first we calculate the probability, that a single day has, that its minimum temperature is more than 3 times the mean. So, p(X > 3u ) p(Z > (3u - u)/2u ) p(Z > 2u/2u) p( Z > 1 ) 1 -...

    Question 3(i) 36 Total Values. S = Sigma sign. S(x-45) = -148 Open the brackets: Sx-S45 = -148 Sx = sum of all the different values of x. s45 = Sum of all the 45's. Since there are 36 total values, it means sum of 36 45's. So, S45 = 36(45) = 1620 Sx = -148 + 1620 Sx= 1472 Mean...

    October November 2009, Paper 5, Question 2 (b) (i) We have to calculate the moles for the Iodine reacted. It should have been simple, except that the Mark Scheme says that using the Mr for Iodine, i.e 254, instead of 127 is incorrect. Why? For diatomic molecules, we use the Mr, which is twice...

    Physics practical tips

    If the graph is a distance time graph, the Y is distance and xcm is the Time s, Gradient is Y/X so the units will be cm/s Just divide the Y with X and you get the units. And if they cancel out for example if the Y is Speed and X is time, SO gradient it Speed/time and since Speed is...
