Jason states the following prediction: “As the air temperature increases, the air in a balloon will expand, increasing the circumference of the balloon.” What is the dependent (outcome) variable of this situation?

It should be cryosphere and hydrosphere

That is true tge cactus as a structural adaptation to its envirinment has it leaves reduced to spines. but this doesnt mean it cant produce food it produces food because of the presence of chlorophyll in its stem

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
