[Jevin Sanoo]

W

3, 4 were correct but i guess beside this 1 also seemed correct to me

What was option 1 btw?

What was option 1 btw?

High blood pressure!!!!

 

[Jevin Sanoo]

I guess your answer is correct. And for the question which asked which one had a single membrane, what was your answer?

 

[ijjukittu]

I guess your answer is correct. And for the question which asked which one had a single membrane, what was your answer?

Ummm can't memorize that question exactly!!!!.........the options were mitrochondria, chloroplast,nucleus, ribosomes n golgi apparatus???
So! I did ribosomes n golgi apparatus

 

[ijjukittu]

golgi apparatus n lysosome

Were they ribosomes / lysosomes??? Well!!! i also did these two

 

[ijjukittu]

my bio book says ribosomes do not have a membrane

I know i don't remember the correct option only!!!!

 

[Jevin Sanoo]

golgi apparatus n lysosome

Ummm can't memorize that question exactly!!!!.........the options were mitrochondria, chloroplast,nucleus, ribosomes n golgi apparatus???
So! I did ribosomes n golgi apparatus

Same for me It was lysosomes btw.

 

[ijjukittu]

Same for me It was lysosomes btw.

Ok! so i did lysosomes n golgi apparatus

 

[ijjukittu]

wasnt dat 5 micrometers? do u remember da magnification? was it 2000?

it was x200

 

[Alice123]

it was x200

ooops i got dat wrong

 

[Jevin Sanoo]

ooops i got dat wrong

U should have got 10000 micrometers then u divide it by 200 to get 50 micrometers.

 

[ijjukittu]

do u hav physics? u givin yr exam dis session?

Nop!!!! i have already given my physics ppr in may/june session

My doubts: question 33 (heart failure).. *high blood pressure . *reduced oxygen supply to cardiac muscles . *deposition of fats ... I am 70% sure though
Also that question about which will give equilibrium, I am not sure is it active uptake or fasc diffusion.. and the question about Beta chain of Hg I answered "primary secondary and tertiary"

 

[Omar Hosny]

facilated diffusion

what about my other answers?

 

[Omar Hosny]

Length of Prakoaryotes ? A or B

 

[ijjukittu]

facilated diffusion

i wrote ''active transport' as it takes from a lower to higher conc. so the no. of molecules at the other side would keep on increasing..n no equilibrium would establish! Beside this, equlibrium involves energy!!!! n active transport is an active process!

 

[Jevin Sanoo]

Length of Prakoaryotes ? A or B

I answered C.

 

[Omar Hosny]

i wrote ''active transport' as it takes from a lower to higher conc. so the no. of molecules at the other side would keep on increasing..n no equilibrium would establish!

i did active uptake cuz fasc diffusion depends on no of prt channels, if there was no prt channels no diff will occur

It is active transport

 

[ijjukittu]

I answered C.

It was B!!! for which question are u talking about???
