There was a mistake in the o'level paper itself:

The question with the plant which eats water fleas; thee was a subquestion asking for wich chemicals and the uses fro those chemicals! it was a three marks question but the answer area was like:


Chemical: _____________________________
______________________________________
Use: __________________________________
______________________________________

It should have actually been:

Chemical: _____________________________
______________________________________
Use: __________________________________
______________________________________
Chemical: _____________________________
______________________________________
Use: __________________________________
______________________________________
Chemical: _____________________________
______________________________________
Use: __________________________________
______________________________________

sighs the 8 OR question on how the fetus obtain metabolic requirement, use it and how it loses metabolic waste. it was a ten mark question and i started off with the mum eating food then the food got disgested , absorbed and going to the blood stream. but guess i elaborated too much my space was full before i touched on the placenta part. and when i read back , i hadn't really written down anything that would carry marks but i just didn't have enough space to do any correction anymore. and it was the last five minute.

the HOW the germination requirement was obtained , i wrote WHAT THE REQUIREMENTS are used for instead ,i don't know why i did that. but again , i just didn't have enough space to do correction!!!!!! IT'S DRIVING ME NUTS TO REALISE THE MISTAKE BUT NOT BE ABLE TO CHANGE IT.

and i got all labellings wrong. no more hope for an A. I even missed out one question on drawing lines on the ribcage? i totally did not see that question at all. it just tells how , uncareful and unfocussed i was.

I AM SO SAD t__t

From what stucture is the roots formed?

 

[Prince III]

Mimmi nice effort of compiling the question

but just wanted to point out for the Question 2
the first part which you missed was to write advantage of the insects and a dis-advantage of the insects

and for the second part , the question stated that
" why the percentage of insects starts to increase from the second year , untill the percentage reaches to the original percentage of insects "it was not at all mentioned that after the first year the insecticides were still added to the crops

for the Question 4

you missed the last part which stated that" suggest and explain would the offspring be genetically identical to the parent "

 

[Shiki Misaki]

From what stucture is the roots formed?

From the radicle.

 

[jazzangel16]

Okay

 

[member]

From what stucture is the roots formed?

From the radicle.

shouldnt it be plumule , because that part did do go under the ground :shock:

 

[member]

G = bronchus
F = bronhciols
H = external intercoaster muscles

am i correct ?

and how were we suppose to draw the posiiton of chest cavity when breath in
please sombody tell

 

[Shiki Misaki]

Plumule? :S Roots are developed from the radicle and not plumule, even though, no roots were formed in the image.
Besides they didn't say 'by referring to the image'.

 

[Shiki Misaki]

G = bronchus
F = bronhciols
H = external intercoaster muscles

am i correct ?

and how were we suppose to draw the posiiton of chest cavity when breath in
please sombody tell

F is bronchioles, G bronchus and H intercoastal muscles. Right.
Chest cavity increases since volume of air inside the lungs increases.

in paper

F was bronchioles, G was bronchus
