What did everyone say for people being resistant to the bacteria in a population or something??
I put herd immunity as I had NO idea

I think I put natural selection for that? I didn't have any idea either though!

You had to say that the person had to breath in at the strongest possible inhalation and breathe out at the strongest possible exhalation ect

The percentage increase was 3140%. The question asked the percentage increase between 51 and 1652. 1652/51=32.39..
Ans*100=3239
-100=3139.21...
3SF=3140%

I put natural selection but I was unsure as that is the mechanism and it was worded badly imo
