    Careful.. It is 'clonal' selection theory. The lymphatic system is a system of vessels containing a fluid called lymph. The system consists of several macrophage-containing lymph nodes which the lymph passes through. This acts as a form of non-specific defence as any foreign particles in the...

    re: HSC Chemistry Marathon Archive Yep that's basically it. Good job! The reason why the value is lower for weak acids is because heat is required to ionise them, meaning less heat is released overall.

    To some extent, yeah, but the first one is mainly about where they are produced, features and the type of immunity they control (i.e. either cell-mediated or antibody-mediated) whereas the second one requires a brief outline of how the immune response occurs, their roles and how the B and T...

    Nah its not bacteria because they do have cell walls. Its a protozoan. In terms of describing you would mention stuff like relative size (larger than bacteria, smaller than fungi), whether it is procaryotic or eucaryotic (eucaryotic) and any diseases it causes (malaria).

    I think your answer is a pretty good overview already. Although unnecessary, you could mention the names of the chemical cytokines released by helper T cells (i.e. interleukin-2) just to demonstrate knowledge. If you have any questions from this dot point though, feel free to ask. Since no one...

    I would classify it as an interaction, because without it the immune response would just continue (i.e. cloning more and more new T/B cells), unaware that the infection has been defeated which would further lead to autoimmune diseases.

    Its fine haha. In an exam though make sure you also define hybridisation and mention it's purpose (to reach hybrid vigour).

    Conflicting Perspectives Essay

    You aren't expected to do all of the studied chapters or your analysis wouldn't be deep enough. Just do about 2-4 chapters and highlight the relationships with your related text. It's up to you whether you have a separate paragraph for each chapter or you mention a few (not too many) chapters in...

    How many English quotes have YOU got to memorise?

    I don't think its necessary. Most of my quotes are quite short anyway (3-4 words), so I embed them into the essay. I think 4-5 should probably be enough.

    Smallpox is a deadly virus which causes high fever and fatal rashes. Smallpox was responsible for the death of many people, greater than any other infectious disease. The World Health Organisation planned a mass immunisation program which was believed would eliminate smallpox. Proving to be...

    How many English quotes have YOU got to memorise?

    I've got about 6-7 quotes per paragraph in my essay. So that would equate to about 85 quotes.

    Mitosis is the division of cells, producing identical body cells. This allows for growth and repair of any damaged tissue, integral to the maintenance of health in organisms as it means cells will function normally. On the other hand, cell differentiation involves the maturation of cells meaning...

    The timeline mainly indicates attempts at producing vaccines and seeing as they were all unsuccessful, I don't think it has enhanced 'understanding of malaria.' Maybe just learn one example though to mention if there happens to be a 7-marker on understanding of malaria.

    I think with cell death, the whole granuloma is engulfed by phagocytes. And for phagocytosis, the phagocytes engulf the foreign particle and release enzymes. Cytotoxic T-cells release the toxins during the immune response.
