Hi,could you please give us a hand.I've got this biology project which has to
be in by next week,thing is you see I don't know anything about it,well
anything that has any chance of getting me an "A*" or even an "A." It seems
you know a thing or two about yeast.The Investigation question is,"Investigate
the carbon dioxide pruduction of yeat,and the effect that anerobic respiration has
on the rate it is produced."I was told I had good,accurate results."Heat was the
variable changed in the first experiment.The first temp. was 30degrees C. and
from then on went up every 10degrees C. Until they were de-natured at 84
degrees C.I don't know why I got the results I did and I don't know why they
were de-natured.The second variable I changed was concetration of heat.Once
again I got good results and once again I was stuck on prediction and conclution
I started with 10ml of 25%glucose and 10ml of 20%yeast I went up 5ml of yeast
every time to 25ml.
