    No usually they credit diagrams but in tissue fluid it wont be accaepted due to explanantions of hydrostatic pressures etc that arent eveident from diagrams

    for tick the boxes i ticked the first 2 on first row and middle on on second row
    I did that too because the diploid number of the cell was four and the second one was going through mitosis as it would produce daughter cells with four chromosomes in each cell if it where to divide and the first two had homologous chromosomes but everyone is saying that for mitosis it's the last too but the last one is meiosis two phase I thought

    I think you may have measured a bit too high

    You know the questions about the three different cell stages, there was one questions about what is happening at chromosome J, i couldn't think of what to put so so i just wrote the chromatids are crossing over? What did everyone else put?

    For the last one I spoke about increasing the chance of bacteria developing resistance. Then it can be passed on vertically or horizontally. And may be spread to humans.

    Uh I didn't talk about horizontal and vertical translations :/ I did however mention it would render the existing antibiotics used useless.

    the 50 um on the paper was like 1.6cm, the distance from the two points was 6.4cm

    6.4/1.6= 4

    50*4

    et voila
    probably depends how you measured it so they might accept a range assuming the method is correct/wrote your working out down

    Crossing over of the chromatids in the homologous pair of chromosomes so the combination of alleles is different

    I only described the tissue fluid process for renal artery and vein, i believe this is the right anawer because blood circulation in unit 2 was only about tissue fluid and the heart process is unit 1

    Because the length on the leaf was 6.4 cm and the length of the bar that stated how long 50micrometers were was 1.6.
    So you had to do 6.4 divided by 1.6 which was 4, the you had to times 50 micrometers by 4 which gave you 200.

    i put smth like,,
    dumping shieeet in the river changes living conditions so organisms which could otherwise survive in the river were not able to as theres plenty of shiiiet in the sewage i.e. waste which could be harmful to certain organisms; some of these migrated elsewhere or died due to the conditions. tldr; only specific organisms could thrive eating sewage shiiiiet so thats why the index of diversity was lower.
    Please tell me you put 'shieeet' instead of sewage. All jokes aside, you should be all right,
