In my opinion, yes. That's what I put down and I'm pretty sure that's what they are.. I'm like 90% certain.So would Cytotoxic T be the correct answer?
Surely, if this was the case both answers would have to be correct.I think they are the same, but I think that Killer T cells is just the name that you call it in school, I'm pretty sure the actual name is Cytotoxic T (Cyto = cell, Toxic = killer) that's how we learnt it in school at least..
I agree with Riproot, think 2 should be C, apart from that - it's all good imoI think that's the only one.
Thanks damn thats a bummer.I think that's the only one.
Me too. :/This was the one I really struggled with. In the end I went with killer but I think now that may have been wrong.
In the textbooks i've used, they all call it cytotoxicSurely, if this was the case both answers would have to be correct.
Yeah I'm just trying to think in terms of how BOS did when they set this out.Surely, if this was the case both answers would have to be correct.
haha don't worry, some people got a lot more wrong.Thanks damn thats a bummer.
Arg. If I got that wrong my MC will probably only be 16/20 which is worse than my trials, and all the past papers I didMe too. :/
Take a look at the posts aboveAlso, wtf is the difference between Cytotoxic and killer? My teacher told me theyre the same thing..... I chose cytotoxic
I focused one the "implications for society" part and used examples to talk about how technological development raises ethical issues in science. E.g. the use of radiation and its link with producing cancer for the fungus stimulus, then talked about genetic engineering such as cloning and transgenic species and why they raise implications for society and how they can be managed effectively.What stuff did people talk about in the last 7 marker question?
- I talked about how biological advancements in identifying cause of disease (Pasteur/Koch) allowed treatments to be developed such as antibiotics (first developed by Fleming - penicillin) --> overall better health for society.
- Then I talked about Beadle/Tatum and their 'one gene-one polypeptide' hypothesis and how this proved that the mutation of a gene causes different proteins to be produced and therefore different alleles --> new traits. Thus, by irradiating the fungus, the new traits are beneficial for society as it can cure bacterial diseases.
- Then I bs'd the rest about enzymes...
I wasn't exactly sure how to explain the enzyme stuff it gave, but I tried anyway.
Yeah, we go pretty indepth into the syllabus and we are pretty much expected to the third column on our own except for the experiments. I haven't encountered an experiment like that ever, so I pretty much just tried for the most logical choice, which was actually clock as they didn't have demonstrate a timepiece to measure for the second variable.I still can't believe you were unsure of the Y lizard one. I set up the data loggers at our school. XD
