yes it definitely would be! Biology was my first exam and I stupidly forgot to ask to take the multiple choice paper! But everyone in my exam left early, I was the only one left at eleven o'clock! I was glad I stayed though because I found an error in my graph in the last 5 minutes and had to redo it

Also the ivy questions, why was only one ivy plant used and was it the fact that not enough leaves were sampled that made the experiment unreliable

I put down that the sample of one ivy leaf was not representative of the whole ecosystem :colondollar:

My multiple choice answers were:
1-D 2-A 3-D 4-D 5-B 6-A 7-D 8-D 9-C 10-B 11-A 12-C 13-D 14-B 15-B 16-C 17-C 18-D 19-C 20-A

Where does everyone disagree and why? Hopefully have 15+ but I'm not sure :smile:

I got the same answers as you for most of them, apart from a few:
3-C 5-A 16-A (I put C, but then changed it to A) 18-A 20-B
The species question was the hardest. And also the one about the diploid chromosome in a donkey; I didn't quite understand the questions:colondollar:

I put zygote for that one, but I'm not sure if it was correct.

Why are 18 & 19 D &C? Can't figure it out
For 18, you work out the percentage increase of 1.5, times 6000 by 1.5 and it gives you 9000.

For 19, you also work out the percentage increase. So it's 15/5 * 100 which gives you 300.

It was mitosis so both had 4 as daughter cells have same amount of chromosomes as original cell


But it said the cell was in an early stage of mitosis therefore there were 8 chromatids. What it not 8 then 4?
Does anyone have a copy of the Section 2 paper?
does anyone have a copy of the sections 2 paper? it would be widely appreciated here :smile:

I put a codon, because i thought that 3 bases made a codon, but when i came out no one else had put that?

Yeah, same. I put 4 pairs, which is basically equal to 8 chromosomes. Right?:colondollar:
Here is a link to the multiple choice section of the paper: https://docs.google.com/file/d/0Bxce3E3FBonNaEdYYUpHOW5HdWM/edit?usp=docslist_api
If anyone has a copy of the written part I would appreciate it.

I think you got Q18 of multiple choice wrong. In 1975 the population is 4000 and in 2000 it is 6000. That is an increase of 2000 so in 2025 it must be 6000+2000=8000
