It was teachers they were vaccinating. I said that the cost of administering the vaccine was less than the cost of lost working hours due to teachers catching flu.

Had no clue about the slime mould, ridiculous question. I just said what I saw and then just said they used molecular evidence as well as physiological evidence.

Yeah, you could test it a few times and then calculate the mean absorbance to reduce random error and eliminate anomalous results. To be honest I don't think a larger range would help, seeing as the absorbance measurement was only 1.4 whilst the absorbance at 2.00mgcm-3 was higher than that I think. It's like if you're measuring an insect, you don't need a meter stick because the insect is so small anyway.

For the lily question I put that I would do a stratified sample using a continuous belt transect using the environmental gradient from moist soil to dry soil. I would count all lily species within the quadrats and plot each number onto a graph to show how population of the lily changes with moisture change.

Is that correct or??

For the question on the dichotomous key question, I wrote 'Does it have fertilised eggs that develop into blastula?'. Would that be correct?

This paper was awful.

Also on the last questions where you had to say why the statements were incorrect... I agreed with the statements LMAO?

In the grid about primary & secondly response asking for speed and quantity of antibodies produced, what kind of this were we meant to put in the boxes?! Seemed a bit vague! I just put low & high kind of thing... 😖
