    Oxygen is always 5 if they're asking about haemoglobin but it's 4 if they're asking about plasma (same with CO2)

    "In this question, he said to hemoglobin .. So the minim no of cell surface membranes is 5 .. But, if he says the minimum number to plasma .. then it’s 4 .. Because I think there is 2% that travels in the blood plasma .. You’ll pass along questions that the minimum no for both co2 and o2 is 4...

    also the 1st question asked about PHOSPHLIPID layers but the second question asked about MEMBRANES (As a whole). That's my clarification tbh

    Oxygen goes from the alveolar's lumen to the cytoplasm of the erythrocyte, and that's 5 membranes: the "top" of the alveolar epithelial cell the "bottom" of such cell the "top" of the endothelial cell (capillary) the "bottom" of such cell the erythrocyte membrane oxygen diffuses through the...

    If X is pointing at ribosomes only then it's protein synthesis, if it's pointing at the ER then it's protein synthesis and transportation so it's either C or D not A or B at all... is ur marking scheme the actual MS or a topical paper MS?

    Guys can u confirm my answers? (These are classifieds and their MS is unreliable) 47-A 33-B 37-D right?

    I also chose D but a friend of mine said it is most certainly metaphase because (btw the question said in ONE nucleus) point X is at the very end of the stage which is before Anaphase (where the division actually happens) so point X is at the very end of metaphase. His theory makes sense tbh...

    look man for this question I also got 12seconds....but then the question said the time between two loudest areas, meaning the time between the two antinodes....the tube was close end meaning it had 2 antinodes and 2 nodes.....the entire thing was 12 seconds so I halved it and got 6seconds...

    these were the answers of one of my friends which he sent me via whatsapp......However there is an arguement over two questions, the power question in the circuit whether it was 6000W or 3750W and the time between two loudest points question which was either 6, 9, or 12....
