In an experiment what should be the relationship between the control group and experimental group?
Sophie [7]

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.

Please help meeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
Mrrafil [7]

Answer:

number 1 answer is 3.

number 2 energy is flowing upwards. ex grasshopper eats the grass, rat or whatever that is eats the grasshopper, and the hawk eats the rat. energy is going up each trophic level.

number 3. if the grass became polluted, then animals would get pollution in their bodies and at some point would die. eventually the grass would die too. primary consumers such as mouse, rabbit, grasshopper/snails would accumulate the most pollution because they directly eat the grass. whatever that is in the grass goes straight into their bodies.
