    Does anyone know whether the answer on the classification table was animalia or eukarya? Panicking thinking I've read the table wrong
    forget it now.. just focus on depth nothing you can do, don't rag your brains out over one mark when you have the potential to get 70 on 07/06/16.

    Thankyou! I think I did get the answer right but I'm just over thinking everything

    Probably no more than 60% probably a bit less or a bit more at most

    Just a guide as it depends on UMS scaling

    I thought a C in biology is around 55%?

    Just realised that at no point in the specification does it say that we need to know the blood clotting cascade :facepalm:

    Its completely random, if they came up in Breadth, there's still a good chance of them coming up in Depth

    The phagocyte detects antigens on the pathogen. It engulfs it forming a phagosome in cytoplasm of phagocyte. Lysosomes containing hydrolytic enzymes fuses with the phagosome and breaks down pathogen. The phagocyte then presents the antigens on its surface for other immune cells to be activated - this acts as an antigen- presenting cell

    Oh ya , I hate that part. . Basically the phagocyte activates T-cells (called cell mediated response) this cell is covered with receptors on the surface do that it is able to bind with antigens presented by the antigen-presenting cells (APC). Each t-cell has different receptors so that its complementary to the antigen. It then activates the t-cell, called clonal selection and starts the clonal expansion (mitosis), this divides and produces clones which are different types with different functions such as: T killer cell- kills pathogen by attaching to antigen, T helper cell - release substance to activate B-cell, T regulatory cells- suppress immune response from other white blood cells to stop attacking own body cell and lastly T memory cells - to remember the antigen second time round.

    This leads to activating B cell (humoral response). It's covered with antibodies and again only attaches to complementary antigens to form antigen-antibody complex so each b-cell is specific. Binding to antigens and substance released by T helper cells activates B cell. This goes through clonal expansion again and makes plasma cells - produces right antibodies for pathogen and also makes memory cells - to produce antibodies quicker in next infection.

    It's part of the Eukarya Domain that's what the person was worried about.. If it asked for Kingdom or domain

    But yeah I agree I think it asked for Kingdom
