If a plant grows five inches when watered with Coke and 3 inches when watered with Sprite, what is a claim that you could make?
Coke makes plants grow taller than sprite.

If a plant grows five inches when watered with Coke and 3 inches when watered with Sprite, what is evidence that you could use to support a claim?

Why is reproduction essential to life?
Because an species has to reproduce in order to continue to exist, even if every member of the species is not able to reproduce.

What are the steps that you take for looking at a slide under the microscope? (think about the lenses and the focus)

you are wondering what type of conditioner would help your hair grow the fastest: comparing head-and-shoulders 2-in-1 and herbal essences. What is a hypothesis that you could write for this question? Don't forget to explain why.
Herbal essences will make hair grow at a faster rate than head-and-shoulders because it is a full strength conditioner and costs more money so must be made of higher quality ingredients.

carb- quick energy
lipid- stored energy

If a plant grows five inches when watered with Coke and 3 inches when watered with Sprite, what is the reasoning of the CER?
Therefore, plants with coke will grow taller than plants with sprite because coke has more sugars that encourage plant growth.
