I'm pretty sure the question just asked to evaluate the 'super farm', not the traditional one.

no it was definitely compare :smile:

it wasnt, it was the evaluate the use of a super farm instead of a traditonal farm was the question, so you needed 2 advantages of the super farm over the traditional, and you needed 2 disadvantages about the super farm + conclusion

Was it? I think I put:

Advantages:
- The cows are producing more milk so it's saving money.
- The waste is being re-used for electricity in 2000 homes.

Disadvantages:
- It's expensive to build the super farm.
- People think it's cruel to keep animals together inside.
- Diseases can be spread easily.

And a conclusion. :smile:

It said evaluate when compared to traditional farming

This test was really easy and i'm expecting an A*. Can't believe people struggled on the last question :cool:

I put something like...
traditional farming- animals lose more biomass through kinetic energy and thermal energy for movement and to keep warm.

super farming- this is intensive farming. Animals can only move around a small area and so they lose less biomass through kinetic energy and since fossil fuels are used to produce heat, animals also lose less biomass through thermal energy to keep warm. Also, a disadvantage of super farming is that fossil fuels are used, releasing CO2 into the atmosphere and humans develop resistance to the antibiotics used by animals.

In conclusion... (can;t remember but I wrote about both farmings)

what was the answer to the last question???...

part a for 4 marks, both parents had Hh alleles
part b for one mark, was the two possible alleles were HH and Hh
part c for one mark , was that you would need to check the alleles of Cat C to make a judgment for Cat D and there was also an answer in the unofficial mark scheme that got posted but cant remember what that other answer was atm

Yes i put all them down apart from the very last question. But why are people constantly saying that both parents had the alleles HH and Hh. Because that can't be true. Because no reccessive alleles could be produced that way. They would all have a dominat allele and that's wrong because 2 of the children had recessive alleles and 4 had dominant alleles.

For the very last question, I wrote that all the children had dominant allelles and so you couldn't investigate children with just recessive alleles becuase none of them had them. (a load of bull cr*p)

SOMEBODY PLEASE HELP.
for 8a i put Hh and Hh. then i wrote that 75% have the disease. and 25% dont. now i was refering to MY genetic diagram and NOT to the cats. will i still get 4 marks? because in my genetic diagram i got HH, Hh, Hh,hh. so hh would be normal but the rest would have the disease. PLEASE ANYONE?

aha i dunno about last one, but anyone saying that parents A and B have HH and Hh alleles, is wrong :smile:

because 2 out of the 6 kids didnt have the disease , so there must be some recessive alleles. a HH and Hh combination would mean EVERY kid had the disease so dont worry you are correct :smile:

slightly annoyed though that this disease was on the new specification and we didnt even get told it lol

Also m8, I wrote that the cells have to be plant cells becuase they have chloroplasts and for the opposite, I wrote that the cell doesn't have a cell wall and so it can't be a plant cell. Would I get those marks?

What do you reckon the mark will be for a grade B?

yes me. I've achieved A*s for all of my chemistry unit 2 past papers. Hoping for 1 in the real thing.
