A scientistis studying a new chemical he hopes will preventinsects from eating raspberry bushes. He sprays the chemical on a raspberry bush and places it with an unsprayed blackberry bush and some insects in a sealed room. He observes insects eating the blackberry bush, but not the raspberry bush. He concludes thatthe chemical works. This situation is an example of (1 point) a controlled experiment. experimental bias. cultural bias. skepticism

Its a Controlled experiment , An experiment that isolates the effect of one variable on a system by holding constant all variables but the one under observation ... The experimental bias is almost an accidental experiment (which this isn't), Cultural bias is the phenomenon of interpreting and judging phenomena by standards inherent to one's own culture which has nada to do with chemistry and skepticism doesn't even make sense!

Silver - actually it is not a true controlled experiment. IF you had two raspberry bushes, one sprayed with chemical and one without - that would be a controlled experiment. By substituting a blackberry bush, he has introduced another variable. You dont know if the insects did not go to the raspberry bush because of the chemical or because they preferred blackberries. Better answer is probably experimental bias.

Nope its controlled he put the bush there for a reason, of course he wanted to see if his solution would work so he put the other bush in there! Duh >.<
