I wrote the fermenter. Did anyone write fermenter?

i did at the end, i said you could place it in a fermenter where oxygen and light intensity is controlled and the yield of insulin production will increase
Where was the fermenter question?
... How did u do the bar chart?

I didn't write in such a detail but i just wrote place it in a fermenter so that bacteria produces the growth hormone.
I did the bar chart with alternating male and female bars, with a key, and obviously heart attacks on the y axis....

I think that is one way of doing it... Mine looked quite similar: except I did one bar (the men) then the other (the women) for one year, then the same for the next year... So it looked like a really tall bar, then a short one, then tall... But hopefully both will be allowed. If anything by the looks of it yours was the better/clearer method!

:frown: Not as good as I hoped it would go.

My brain malfunctioned and decided that there was only one vas deferens. wtf
And failed to mention the word eutrophication despite the fact that I was thinking it the whole way through
And the typical 'fail to read the question' for the stomata one....

I'll have to ace the paper two : /

it is stored as glycogen and i wrote starch :angry:
In the plant structure question, did you call the structure A upper epidermis? Or waxy cuticle? I put upper epidermis but also wrote about the waxy cuticle :confused:
