How did people answer the blood cell count question. Did you have to be really specific like putting in a formula of blood cell diameter = length of field of view (m)/(number of red blood cells x the degree of magnification)

My fave section of the paper-'mirin the 8 marker on the three scientists.

Not sure if my blood cell sketches or bread mould explanation were the best, but good short answer :)

For the 8 marker did people just recount Pasteur's experiment and mention that it showed that microbes caused disease, list koch's postulates and mention that this enabled the cause of a particular disease to be found and connected to the disease and for Burnet did you just touch on the immune response and how memory cells are formed which makes vaccines possible...

The bread mould question confused me... I hated it so much that I left it out, fml. I forgot about it completely...

The MacFarlane Burnet question was... yeah, fml.

Was the Macfarlane Burnet question even examinable? In the syllabus, he's not mentioned in an actual dot point, only in a title.

The 5-marker in Communication about how insects and fish use structures to detect vibrations...I had a MASSIVE brain freeze here. Studied it for quite a long time last night, and then just forgot how to answer it :(
The 8-marker...why did they test us on Macfarlane when there wasn't actually a dot in the syllabus saying we had to know exactly what he did!?!

Yes, they have examined him before, but only in the multiple choice. This is the first time he's been in a short response, which is a bit odd. Thank God I knew what he did- colonal selection theory whooop :D Im pretty sure if you wrote anything about b and t cells then you should get 1 or 2 marks for him.

For the question with the pedigree chart, what did you put for why it wasn't sex linked but recessive?

I also said that the mother, father and husband could be carriers. This would mean that the sons would each have a 50% chance of inheriting the disease.

The mother {female} and sons {males} have the trait. The mother only has sons, so we can't say it's sex-linked. If she had a daughter, maybe she would also have the trait. thus, it can't be conclusively said that it's sex-linked
The woman's mum and dad don't have the disease, but she has it. therefore, parents are both Tt <<meaning dominant= no trait and recessive=trait
