Answer:
Ideally, the experimental and control groups are identical. As much as possible, the two groups should overlap in every characteristic.
Explanation:
At the beginning of your study, you need your two groups to be as statistically similar as is humanly possible. That way, when you control for other variables, you can reasonably attribute any statistically significant differences at the end of the study to your intervention.
Answer:
fruit weight
Explanation:
In an experiment, the dependent variable is the variable that responds to the changes made to the independent variable. In other words, the dependent variable, as the name implies, is DEPENDENT on another variable called independent variable. The dependent variable is the variable that is measured or recorded by the experimenter during the experiment.
In this case where a student is studying the effect of fertilizer on fruit growth. He uses 6 tomato plants, which were given different concentrations of fertilizer (independent variable). After the experiment, the weight of the tomato fruit were measured. This means that the FRUIT WEIGHT is the dependent or responding variable.
awnser is high concentrations of oxygen
75% it will be RR or Rr and will have red eyes 25% it will have rr with different colored eyes.
