Q20) Distance between centromere and poles decrease as time goes on Because The get pulled towards the pole so i should be 1! Now asn could only be A or B.Plzz expain me thez questions
Q21 => first of all note that UAG is for RNA while we r given the strand of a DNA...Plzz expain me thez questions
i did that for her but if i've done any mistake then do correct itQ20) Distance between centromere and poles decrease as time goes on Because The get pulled towards the pole so i should be 1! Now asn could only be A or B.
Distance between centromere of SISTER CHROMATIDS increase because they become seprated and pulled towards the pole so it should be 2. So the Answer is A.!
DO YOU NEED Q21 ASWELL?
PerfectQ21 => first of all note that UAG is for RNA while we r given the strand of a DNA...
so for ths question if we put T at position A then it'll gve TTC i.e. AAG n that's nt the stop codon... then move to the option B.. when we put T in between A n C it'll gve ATC and when we cnvert it in RNA strand then it'll chnge to UAG.. n yahi stop codon hai to ths is the correct ans
q28 june 2008 > one complete cycle is atrial systole (AS) + ventricular systole (VS) + ventricular diastole, in the figure one heart beat takes 0.75s, cross multiplyPlzz expain me thez questions
Q16=> Jani ths is the same question we did at scul..... at y-axis we r given with initial/final.. so when the water potential is same then no osmosis will occur n there will b no chnge in length... suppose that the actual length of the potato strip is 2cm ...as there is no osmosis the initial/final=2/2= 1 cm... so frm the graph on y-axis check where it is given the value of 1..then read the x-axis reading at that point n u'll get ur ans... n that is 0.45s ....Plzz expain me thez questions
no... but still u shud knw the basics of it that we've studied in igcse or olevelsIs meiosis in the As level syllabus?
yes...Is meiosis in the As level syllabus?
so isn't it the same as it was in olevels?yes...
all you have to know about meiosis is as follows:
- definition
- number of daughter cells produced
- type of offspring produced
- no. of chromosomes in each human cell
- type of cells produced
- use of this process
i told her what i know......so isn't it the same as it was in olevels?
post ur other doubts in that thread... n stop sayng thanks to me.....Thank u so muchhh nabil, mehria and salik dat realy helped! So nyc of u
But the different phases/stages of meiosis aren't, am I right?yes...

Yes, this is just in A.2 ,,,,,,,all u need to know is about mitosis stages onlyBut the different phases/stages of meiosis aren't, am I right?
Potometer is not that difficult....just go through the book once, i think you will understand it....and i have seen a potometer related question in p2..so there's a chancei am in doubt with potometer , i don't have for it enough info.... can it come in 4 marks question?
there is repeated question for diseases that can be cured by anibiotics in p1, i know that virus an and any eukaryotic organisms cannot be cured due to many stains they have, but it is sometimes tricky!
yes, they aren't required by AS-qualification as joanna omar saysBut the different phases/stages of meiosis aren't, am I right?
