Was it not temperature???

What did everyone get for the question where it asked why the athlete breathed more heavily??

what did you guys put for how can humans increase the cod population?

What did u guys get for that question where it asked why the penguin numbers decreased bc of cod dying

What did everyone get for why there was no oxygen in the red blood cells or a diabetic ?

oh really? i thought it said 280 million for 1 lung and asked for SA in human body?

What did everyone get for the question where it asked why the athlete breathed more heavily??

What did you guys get for the question on why tube A was acidic, I said that because it was in the dark, it couldn’t go through with photosynthesis and therefore there was no oxygen produced and had to use anaerobic respiration which produced lactic acid but it was just a guess.

i got because of the lack of oxygen the athelete struggles to respire and begins to respire anaerobicaly

what did you guys get for the question where you had to make a practical to investigate light intensity as a limiting factor??

i was gonna write that but i wrote that for the earlier question so i thought it wouldnt make sense for both

i got keep light a fixed distance but heat the thing in the water bath at a range of solutions the temperature with the lowest bubbles shows its the limiting factor or something

oh I just said that the muscles are respiring faster and so more oxygen is needed so the athlete is breathing more to take in more oxygen

i got keep light a fixed distance but heat the thing in the water bath at a range of solutions the temperature with the lowest bubbles shows its the limiting factor or something

bro i said maximise all the other things like put the lamp close at a fixed distance, increase carbon dioxide increase temp then use cold water with the other things still maxed out and the rate would fall dramatically

What did people put for count the days of the menstrual cycle because I put 25 but I heard someone say the question only asked for half the cycle

bro i put that and then crossed it out. i thought animals didn't produce lactic acid during anaerobic respiration, I thought they made ethanol and co2 only so I was like the h+ ions in ethanol dissociate in the btb solution making it more acidic😭
