I put conjunctiva, what does the sclera protect the eye from? the conjunctiva makes more sense.
Also is sulfur dioxide not a greenhouse gas? That's what I put
Sulphur dioxide is a greenhouse gas. I put sulphur oxide by accident lmao. And idk in the book it just said the sclera was the tough outer part of the eye so I put that
It was my first ever igcse exam so I was so nervous that my hand writing looked so bad coz my hand was shaking, do u think they will cut marks for this?
Same here 0_0, apparently my handwriting is that of a five year old.
I got 0.0075 but apparently the answer was 0.75 LOL
I think 0.0075 is fine mostly cause that's what I put, but also because if I remember correctly the units weren't specified so if you put 0.0075 m/s that was fine or 0.75cm/s that would also be fine

I put that he will transport more oxygen every breath because he uses anaerobic respiration so to avoid the heart having to beat constantly and quickly which may cause the arteries to be blocked, it beats less frequently but with more force to deliver more oxygen every time. Thus, lower heart rate.. Anyone agree?
Thats PARTIALLY correct. Nothing to do with anaerobic respiration as far as I know
Its all about stroke rates, and how athletic hearts are more muscular, and hence, like you said, pump more oxygen per contraction than a normal person, hence require less pumps (beats)
What do you think that two marks were for? i said Adrenaline is produced by the adrenal glands to prepare for exercise. This increase the heart rate. Do you think that is two marks? Also was the anomaly Thomas?
