wat u wrote for the cornea question?

Cornea doesnt contain traces of blood so no RBCs and no antigens and no foreign antigens are in the cornea

i wrote no antibodies secretion is this ryt??

ok wat u wrote for the DNA question?

 

[areebaization]

ok wat u wrote for the DNA question?

There were alot of points for it. We can classify which family it belongs to genetically and we can give it a genus name based on that.

I wrote find out if the genes match or not......wat u thnk?

 

[afshinsalim]

They asked us about Villi (which I wrote as Cilia, god knows why) and they gave us a cute little night animal for the picture and asked us to write about mammals.
They gave us selective breeding question and some stuff relate to it.

Well i feel sorry 4 u. I just hate that topic of breeding. loll

I wrote find out if the genes match or not......wat u thnk?

yeah I guess u shld get marks for it, it's logical

 

[wooowooowoo]

I hope GT is low for us, lower than yours.

also for decrease crop, I wrote
1)soil erosion.....
2)due to climate change by global warming...wat u thnk about this point...I'm not so sure here???

U could get a BOD here coz again anything logical will get a BOD.. So yeah best of luck with it

wat u mean by BOD?

 

[areebaization]

wat u mean by BOD?

Benefit of doubt... Something that isnt in the marking scheme yet makes sense gets a BOD, in this case the person gets the mark(s) allotted for the question.

 

[Reem2195]

I wrote soil erosion
and I also wrote that pests would eat the crops because deforestation of other areas of the forest means that they have less food so they start feeding on the yield.... not sure if it's right though- as I said b4, last question sucked for me

thanks for replying*
wat did u write for the advantages for humas last question??

 

[Abhihsek]

V2 was awesome , the last part was a bit tricky with all the genetic engineering and selective breeding.... so many questions on plants, nothing from the first or second chpt except the freaking monkey! I finished with like 3 minutes left, overall I think I'll manage an A*

wat did u write for the advantages for humas last question??

adv. of recyling?

 

[Abhihsek]

thanks for replying*
wat did u write for the advantages for humas last question??

medicinal value of plants
products from animals
biodiversity maintained that provides variety of genes that can be used for genetic engineering
weather patterns remain stable (deforestation makes weather patterns change)
soil around is fertile ( usable for farming), etc

wat did u write for the advantages for humas last question??

okay yeah I get ur question now
1)I wrote that toxic poison (pesticide) build up in minimized <---Don't worry if u didnt write it they could be alot of answers to it
2)Energy intake and nutient intake is more as primary consumers.
3) Diseases such as bird flu could be prevented

i wrote no antibodies secretion is this ryt??

No antibodies or no antigens?
If u wrote antigen that is correct

 

[IGCSE O/L student]

salamz! wat did u write 4 da pH question?
