To test how fertilizer affects tomato plants , a farmer divided a field of young tomato plants into 10 plots of equal size. the farmer then put fertilizer on half of the plots and no fertilizer on the other half of the plots. the control group in this experiment was :

Control Group - tomato crop on which no fertilizer is applied

Explanation:

The control group in this experiment is the tomato crop on which no fertilizer is applied.

A control group in an experiment is the group on which the testing/treatment with in an experiment is not applied in order to compare it with the group that receives the testing/treatment.

Hence, tomato crop (which do not receive fertilizer) are the ones whose production will be compared with the tomato crops that receive fertilizers.

answer; a male inherits only one allele of the x-linked gene controlling hair color;

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
