ME too i also wrote A

what was the answer to possible movement of nitrates and osmosis in root hair cell ?

I wrote both could move in and out

 

[Prince III]

yes as the question stated possible movements they both i.e water and nitrates could move in and out

what was the correct statement for Hh ?

Option B was correct
stated something like
" they are two alleles made up of genes " something like that

that graph on number of different types of litchens and distance from the power station
the answer shoud be " there are fewr different types of litchens near the power station "

it shouldnt be sulpurdioxide one because that cant be concluded from the graph
there might be any other reasons for inhibiting the growth of litchens

I got the same answer.

umm.... i cant believe they tried confusing us using words that are scrambled =S

but yeah! there are atlease two different alleles for the gene for height

Exactly! also, sulphur dioxide wold make acid rain and that would rain away from the power station since there is always wind blowing

Why is mosquito a good vector for malaria? its in a past paper =S

i answered "it has wings" because;

a) Il lays many eggs : malaria is not passed onto a mosquito's eggs
c) it makes a noticeable noise : WRONG!!!
d) It mates several times : malaria is not passe from one mosquito to other by mating

where was mitosis taking place in female reproductive system ?

 

[mimmi]

where was mitosis taking place in female reproductive system ?

everywhere othe than the ovary

 

[creative22]

everywhere othe than the ovary

No! mimmi mitosis was taking place in just one labelled part that was in the middle

oooh! doesnt the egg get fertilized in the follipian tue? and it starts dividing? and by the time it reaches the uterus (at the conter), it already has many cells !!!

 

[basch]

yes but the option you're saying was not given in the question. the answer is at the wall of the uterus. there was only one 'tick' for the answer

 

[creative22]

yes only that part was under going through mitosis

 

[mimmi]

yes but the option you're saying was not given in the question. the answer is at the wall of the uterus. there was only one 'tick' for the answer

no it wasnt! there were four options something like this:

a) x
b) y
c) z
d) x and z

if not, the question is wrong! mitosis happens even in the follipian tube!

 

[jazzangel16]

Yes as soon as the egg is fertilized it undergoes several mitotic divisions even in the Fallopian tube

do you think 78-79 or 75 above will be an A? i am scared, sigh.

 

[creative22]

do you think 78-79 or 75 above will be an A? i am scared, sigh.

No!
that is low i guess atleast 83 % would be required for A
