For independent variable i got: temperature
Dependent variable i got volume of oxygen (something like that)
For controlled i got light intensity
For the variable not controlled i put carbon dioxide concentration

For the graph question after i said something about how the rate of photosynthesis was highest at 30 degrees because of steeper gradient etc etc. Also said that the enzymes don't denature at high temperatures (something along those lines anyways)

Time was the independent variable , don’t remember dependant variable

Six marker to compare and contrast the circulatory systems between a mammal and a fish...

Did anyone talk about exchange surfaces at all?

But they said excess CO2 so surely that didn't make it limiting

For a table near the end did anyone get
Aldosterone
Cortisol

Not required as only circulatory systems had to be compared so just talk about single/double loop and closed/open

Dependent I put oxygen conc absorbed and independent I put temperature as that’s what they were changing

Nope , just said about single double and close circulatory system and how the vessels like veins and arteries play a part in it
Not very confident in that one 😩
