Hi everyone!
I just got back my U3 AoS 2 SAC back and wow... THANK YOU ALL SO MUCH!
I took in most of the tips from those Study Guides for Bio and I went from a 79% on the first SAC to 89%!! Thank you so much for being such a good resource and answering my questions etc and now I'm getting really excited for the rest of the year learning bio!!
So anyways sorry about that happiness burst and please answer some of my questions (when you have the time of course)
:
- Describe what a vaccine against strangle disease may consist of 1 mark
I wrote down 'The foreign antigens of Streptococcus equi' while on the assessment report it said 'the
attenuated form of strangles bacteria which still includes the specific antigen'. Do vaccines always contain attenuated pathogens or can it still be 'activated' per say?
Maybe because I haven't revised U3 AoS 1 in a while but here:
- Which one of the following scenarios is consistent with a prokaryotic pathogen?
A. The influenza virus is inhaled by unsuspecting person in a lift
B. Misshapen prions are consumed because a person ate undercooked brain
C. The malarial plasmodium (protist) is transferred from a host to another person via a mosquito vector
D. A cholera bacterium is consumed by drinking water
* I picked C but the answer is D... is it because I got confused with the whole eukaryotic vs prokaryotic thing? If so, what specific organisms are categorised under eukaryotes or prokaryotes? (I'M SORRY THIS MUST BE SUCH A SIMPLE QUESTION BUT I JUST FORGOT LOL
)
