What are the 3 parts of cellular respiration?
Glycolysis, Krebs Cycle, Electron Transport Chain
Write a hypothesis for the following question: How does amount of water affect the height of a plant?
If you increase the water, the plant will grow taller, because the water is used for photosynthesis.
What is a pioneer species?
What type of chemical bond would Lithium and Flourine make?
Ionic bond

Bonus if you can do 6
Ill check
What are the inputs and outputs of Photosynthesis?
CO2 (Carbon Dioxide)+ H2O (Water) + Light --> O2 (oxygen) + C6H12O6 (glucose)
What are all the variables in the following investigation: How does brand of gas station affect the miles per gallon on a car?
IV, DV, 2 Control Variables
IV: Brand of Gas
DV: MPG on Car
Control Variables: Type of car, where you drive it, etc.
What type of growth would happen to a population if it had unlimited resources?
Exponential population growth
Why does water dissolve substances so well?
It is polar and has charges
If a cell is a solution that has more solute, would that solution be hypertonic, hypotonic, or isotonic. What would happen to the cell?
Hypertonic and the cell would shrivel
What are the inputs and outputs of respiration
Inputs=Glucose and Oxygen
Outputs= Carbon Dioxide, Water, and ATP
Create an investigative question and then write the variables and a hypothesis
Depends on what you chose
If you did the quadrate sampling method for pine trees in a 5x5 square mile area and counted 6 random 1 miles plots as 7, 6, 9, 10, 4, 11. What is the population estimate?
196 trees
