Biology Paper 61 ANSWERS ARE HERE!!!!!

[Abu mota]

for the variation one im not really sure but ur answer makes sense to me and for the osmosis one, this is my opinion as they are comparing results which means that the difference will be the same if they used the same length for both but longer and longer time

 

[Abu mota]

for the labelling question did u label the empty space for the mesophyl layer or the walls?

i dont understand what do u mean but for the mesophyll i labelled the black part in the middle.

 

[Abu mota]

Should we label the white or black area for mesophyll cell?
And the concentration of sugar, we had to mention something to do with colour darkness?
And last question which was 1 mark, what was the answer?

for the benedicts one there is a range of colours from green to yellow if weak and if strong from orange to red.

yes i did

epidermis is the outside layer the black part in the middle i wrote the xylem vessel and for the mesophyl i choosed guard cells not sure about last one

 

[aliasal]

yes i did

thank God !! BTW nice name lol

i dont think guard cells are part of the mesophyll layer

 

[Hamzeh S]

i dont think guard cells are part of the mesophyll layer

yaa i had a doubt its ok

in the onion leaf question, what did we have to measure ? The total diameter or the inner part ? I measured the outer part only.

 

[whitetiger64]

What was the answer to the last part of the insect part? Was it annelid or nematode?

annelid

 

[Beedo]

I wrote thoe in improvments :
1-use same temprature for the 3 leafs
2-repeat 2 more times .
is that right?

I got it 70mm and magnification x14
I think I made it wrong like most of people & you did it right but not sure about it

last question I wrote as some of them are still growing is it correct??

It is actually correct BUT you should have written continuous variation.

And the concentration of sugar, we had to mention something to do with colour darkness?
And last question which was 1 mark, what was the answer?

1) label a black cell
2)yes colour darkness
3) It is a form of continuous variation.

ASK ANYTHING I AM A BIOLOGY EXPERT. THIS IS NOT A JOKE!!!!

Heyy how about the qu. Of analides and nemtodes

 

[Ahmed GolD]

Heyy how about the qu. Of analides and nemtodes

Nematode was letter C
And the others were Annelida.

 

[Ahmed GolD]

only frequency
