Hi,
In AQA Biol 5 the essay I title I wrote about was " Explain how organisms exchange with their external environment to maintain their internal environment "


I talked about
temperature regulation
glucose ( ingesting it ) insulin etc
heart rate with co2 excersise chemoreceptors
seeing predators and adrenaline

Is talking about ingesting glucose correct? (i.e. then going on to explain what happens with that to maintain an internal environment) or because it was exchange you needed something in and something out.

What I'm saying is does exchange have to necessarily mean in and out, or does it just mean cross over a surface?

Do you think the science marks are still available even if your not directly answering the question? is it just relevance marks we loose?
