For the one with Salmonella, did you guys put pathogenic organism?

For humans impacting environment, i put spraying pesticides and the chemical was DDT... is that right?... btw would burning fossil feuls be right for that question?

Feel free to ask other questions.
i put minerals in soil to affect plant population.

for paper chromatography: the plant extract was touching the solvent and it's not supposed to

ask more questions if needed
 
Remember that chart, was it something like this,,


frog.......decrease in number.................gorila......human
forgot what was in between


and was this a bad way of using, and gel electrophoresis is better because it shows similarity, and this shows diffrence?



EDIT: I used coal, and that it is bad because it's non-renewable, and it affects the air we breathe. is that good?
 
i put that it was a parasite- not sure if its right though
and for the humans impacting the environment, i put that cars make pollution.. i screwed up the whole test.. it was rlly hard
 
Yes, I got pathogenic organism :]

I put pesticides too. I either put DDt or PCB I can't remember but both however are chemicals found in pesticides :]
