The variable that is purposefully changed by the scientist in a controlled experiment.
Independent or Manipulated Variable
100
The process that single celled organisms use to reproduce asexually.
Mitosis or cell division
100
The process where organisms with adaptations survive and reproduce more than organisms without adaptations.

Group in experiment where the independent variable does not get changed. You compare your results to this group.
Control Group

Name two things that are different between plant and animal cells.
Plant cell has a cell wall, a chloroplast, and a large vacuole - animal cells do not.

Why is energy lost at each level in the food chain?
It is used in life processes, and lost as heat.

What is leading to global warming?
Increased GHG's from burning fossil fuels

How do you make an experiment more valid, or reliable?
Repeat it, do more trials, or have a larger test group.

What is the difference between a renewable and non-renewable resource? Give an example of each.
Renewable can be replenished, non-renewable cannot. Renewable = wind, water, solar Non = oil, gas, fossil fuels, coal
