9700/32/MJ/14The picture isn't clear.
Can you mention the which paper it is?
thanks..its june 2006which year maybe we have to say that rubisco catalyses co2 and rubp reaction ,co2 fixation
becasue in ms we have collision between co2 and enzyme above the confusing point
i think we should say that in C more co2 is there to be fixed . more co2 collide with rubp so more enzyme substrate complex forms
this reaction is catalysed by rubisco
by the way its AVP so u can anything but related and valid not only this confusing point
Oh you need a slide for this. -_-9700/32/MJ/14
They mean characteristic features of xyrophytic plants that greatly reduce water loss ie transpiration etc.View attachment 59920
What do they mean by reducing water potential gradient?
We measure the size of cells, tissues or large organelles (such as mitochondria, chloroplasts) using micro metres. However, to measure small orgenelles, such as cell membrane (7nm), cell wall, ribosomes or lysosomes, we have to use nano metres.View attachment 59128
Can someone please tell me why the answer is C?
Actually, I read that in a mark scheme of a paper 2, that nuclear envelope reforms during cytoknesis. MCQs are just soo confusing!Telophase consists of nuclear envelope reforming , in which cytokenesis specifically refers to division of cytoplasm and cell into two by constriction from edges of cell Only!.
Check out corsebook book mitiotic cell cycle chap.
Some answers fro MCQs are surprising.People here suggested that I take alook at examiners report.You should also try that maybe it can help you.View attachment 59919
Why can't it be cholera? Only sickle cell anemia and tuberculosis can genetically be transferred but the answer is B when A is equally likely
It's simple, bro. Look they said what is ALWAYS true for cytokenisis. Nuclear envelop is only present in eukaryotic cells. What about prokaryots? They don't have any nuclear envelop. So this statement does not hold true for every type of cell. I think you got it now. Right?View attachment 59921
Nuclear envelope also reforms during cytokinesis, why is it C?
yup. get that nowIt's simple, bro. Look they said what is ALWAYS true for cytokenisis. Nuclear envelop is only present in eukaryotic cells. What about prokaryots? They don't have any nuclear envelop. So this statement does not hold true for every type of cell. I think you got it now. Right?
yeah you are right, will read er n future as well, thank youSome answers fro MCQs are surprising.People here suggested that I take alook at examiners report.You should also try that maybe it can help you.

yes exactlyOne possible explanation I can think of is that they didn't mean by genetic transfer only. Perhaps if the parent and child live together it is possible for the cholera bacteria to be transferred through using of same food utensils or something like that.
For malaria there is isn't a direct transfer of the disease; a mosquito would have to bite one person and bite the next one.
But I agree it's a bit silly.

Oh yes I forgot even TB isn't transferred genetically.Yeah, you're right
Sickle cell anemia is a genetically inherited disease. Cholera bacteria can also be passed on to children from parents, if they are living together. Similarly tuberclosis is transferred when a parent coughs, the vapours containing the bacteria may be inhaled by the children, thus again it's directly passed on.
For malaria, it can't be passed on directly. It requires a vector for its transfer. If there is no vector, disease can never be transferred from parent to child, no matter how severe it is.
