what ws dat answer where a picture was given wid labelled X??

variant?

 

[Exo_luhan]

variant?

VARIENT 1

 

[Karim Nabil]

VARIENT 1

ok, then which question are you talking about?

 

[Exo_luhan]

ok, then which question are you talking about?

two structures were shown...we had to identify which structure were they and de what passes in X!!!!

yes, the big hollow thick lined walls are the xylem vessel elements

 

[Tulaib]

anybody here to discuss p12 as well?

 

[Wolfgangs]

There was that cross breeding diagram, what were the numbers exactly and what was the answer?

 

[Karim Nabil]

There was that cross breeding diagram, what were the numbers exactly and what was the answer?

14 breed with 14 then offspring breed with another 14
answer was 42..

 

[Wolfgangs]

I think there was a doubling in the chromosome number right? Can you remind of the exact sequence

Also, was the answer A, B, C or D?

 

[Wolfgangs]

Can someone please answer as soon as possible

 

[Wolfgangs]

14 breed with 14 then offspring breed with another 14
answer was 42..

Dude, was the answer A,B,C or D?

 

[Exo_luhan]

Dude, was the answer A,B,C or D?

B

 

[Wolfgangs]

For the antibodies through the mother, the answer is D, right? Passive natural

 

[Wolfgangs]

Does goblet cells secret enzymes to destroy bacteria? I think it is wrong, right?

And, the transpiration process, involves the mass flow of water through xylem vessel, right?

 

[Wolfgangs]

The question says, which of the 4 processes are involved in transpiration
1. evaporation of water
2.diffusion out of the stomata
3.mass flow of water through xylem tube
4.something about sucrose

Is point 3 involved?

 

[Wolfgangs]

and are you sure about the goblet cell thing? There was another option that made me confused, but I don't quite remember it.
I think it is smooth muscle - constriction of "SOMETHING I forgot what it is" Do you remember it?

Please if anyone remember the last point tell me what is it

 

[silentkiller97]

what were the layers that control blood flow through an artery

 

[Resigned_123]

The option about the goblet cells secreting enzymes was the correct answer as they secrete mucus not enzymes
The layers that allowed the artery to resist changes in pressure were the elastic and muscle layer
D was the answer as anything with smooth endothelium was incorrect as its function is to minimize friction

 

[Wolfgangs]

The Q3 question, the one about active transport, what was it again and what was the answer?

 

[Ahmed Shazly]

The option about the goblet cells secreting enzymes was the correct answer as they secrete mucus not enzymes
The layers that allowed the artery to resist changes in pressure were the elastic and muscle layer
D was the answer as anything with smooth endothelium was incorrect as its function is to minimize friction

Smooth endothelium was correct i think the answer was 1,2&3
