What is the dependent variable?
When an experiment measures the gases a living organism gives off, it is looking at this cellular process that releases energy from food.

What is the independent variable?
This is the final step where you look at your experiment's data to decide if your prediction was right or wrong.
What is a conclusion?
A bacterium splits to become 2 bacteria, then 4 bacteria, then 8, and so on.
R — Reproduction (the process of making more of their own kind)
A student spills chemicals on himself or herself, or some other emergency happens in the laboratory. This should be done immediately.
