What is the independent variable?
Bread, pasta, and fruit all give your body quick energy because they are rich in THESE biomolecules.
What are carbohydrates?
These organelles earned their nickname “the powerhouse of the cell” because they produce ATP.

If one group of plants receives fertilizer and one does not, the unfertilized group plays THIS role in the experiment.
What is the control group?
Muscles, hormones, and enzymes are all made mostly of THESE biomolecules.
What are proteins?
These green plant organelles capture sunlight to make glucose during photosynthesis.
What are chloroplasts?
This type of RNA carries the coded message from the nucleus to the ribosome to build proteins.
What is mRNA?
Grass, algae, and trees all perform photosynthesis, placing them in THIS trophic group.
What are producers?
Plant height measured at the end of an investigation is an example of THIS type of variable.
What is the dependent variable?
Cell membranes are built from a double layer of THESE water-avoiding biomolecules.
What are lipids?
This flexible barrier is responsible for letting oxygen in and waste products out of the cell.
What is the cell membrane?
