QUESTION PAPER JUNE 2012

I am a lower sixth biology student and I was in my classroom in which my teacher let me have a look at today's unit 4 paper. I couldn't take a paper so I quickly took photos of each page on my phone so have had to upload them one by one...sorry that it's all messy but just thought I'd be doing you a favour!

What did you guys get for the last question relating to the use of insecticides on a resistant population.

I said that

Some individuals in the population have the alleles for the resistance against pesticides as a result of mutation. The individuals that don't have the allele for resistant die. The surviving individuals reproduce and pass on their alleles to the next generation.

How many marks would this be worth?

I'm thinking 3/5

I got this plus the resistant pests are better adapted in their environment and more likely to survive and reproduce. So the frequency of the better adapted alleles would increase.

So you'll probably get 3-4 out of 5. :biggrin:

This paper was far too easy. Boundaries will be sky high! My boys found it piss- killed it 75/75 :colone:

According to my school, boundaries will be:
100ums- 75/75
90ums- 71/75
80ums- 68/75
etc

Oh come on that's ridiculous.

sorry but I am talking about anaerobic respiration.

sorry it probably would either stay the same or move up due to ethanol production.

They asked for heterozygotes so it would of been 42.

41 not 42.

(0.51^0.5)*(1-0.51^0.5)*2 = 40.828... so 41% since you are only giving two sf in the question so answer should be to that accuracy.
