What about the last question on the paper, mendel and his findings and why other scientists didn't think it was important ?

sumone in my class put down (cuz he didnt have a clue) he wrote ' Because monks werent considered as brainy :biggrin:

' lol

did anyone get the answer as to why ribosomes cannot be seen under a light microscope? It frustrated me so much :s-smilie:

i just said they're too tiny...probs wrong..i think it might have been one of those questions thats less complicated than you think

1) he wasn't a scientist; he was a monk
2) lack of knowledge and evidence on genes :smile:

@_wikipedia nope, i guessed and said that they were invisible, oh no

@ellen199 it was towards the end i think, it was definitely in there. the mendel question was at the end & the mitosis question was i think page 4 or 5

@kwstudent i did the same, i mean about the length of the leaf :smile:

I got really confused with the person one 77 thing as well because I measured it over 80 as well. Then I realised that the question was asking what the stroke volume was at after 1 minute and the stroke volume was 77 at 1 minute, not the highest point of the graph which was over 80.

That's what I put as well; probably the right answer because "A mitochondria is 500-1000 nanometers . A ribosome is 20nm" And you could see the mitochondria in the diagram
