Hehee oki never mind... Gudd luck for chem u ll need it eh trouble for u eh

 

[TheBaller23]

What did u write for the blood vessels carrying oxygenated blood

V then Y.. lol im sure i answered u before xD

 

[Z.A.M]

What did u write for the two questions that about deforestation

 

[Z.A.M]

V then Y.. lol im sure i answered u before xD

I wrote that hope we r right

i jjust wanted to know ..will i get the mark if i labelled the seed with food storage(reservoir) instead of cotoleydon?

If u get a really gudd examiner

LOL, I doubt it.. a resevoir is a where water is store. But the seed stores enzymes and other things as well, not only water. Relax, it was one mark x)

How do you know I'm in trouble lol?

How do you know I'm in trouble lol?

Well I can tell people in trouble loll my special talent
Pfft ur the one who told me dude
Now answer my question above

What did u write for the two questions that about deforestation

This one ZainH

 

[IGCSE O/L student]

I just wrote Hyphae (Plural).. What's aerial hypha? :S

aerial hypha is correct!

 

[IGCSE O/L student]

What was the name of the fungus thread thingy, I wrote Aerial Hypha

dats correct. but it's actually mycelium

 

[ZainH]

dats correct. but it's actually mycelium

Mycellium/Hypha/Aerial hypha will all be accepted. Im pretty sure.

Well I can tell people in trouble loll my special talent
Pfft ur the one who told me dude
Now answer my question above

When did I tell you that :S? But yeah I am pretty screwed, but doing alot of pastpapers and getting better at them .. I'm feeling more confident now! x)

In reply to your question about the one about deforestation.. could you refresh my memory on what it asked exactly? I've been doing alot of chemistry lol..

i wrote cortex!! i'm a fool!

 

[ZainH]

i wrote cortex!! i'm a fool!

Cortex? Why does that sound familiar..

 

[Z.A.M]

Mycellium/Hypha/Aerial hypha will all be accepted. Im pretty sure.

I C Falluda memory well u did Tell me
Ya so in the last question of exam the third part and the first part asked about cutting trees however one asked about cutting from a small area

 

[TheBaller23]

I'll tell you what I wrote, it doesn't mean that these are the CORRECT answers.
1)One inside was pumule, outside was radicle.. I got that wrong :s
2)BY looking at there DNA we can observe the different genese present, and compare them.
3)It's okay if you messed up an example, I didn't even use an example .. shit.
4)For that mammal question I wrote, external ears, mamary glands , hair/fur.
5)If you wrote enough points worth of 5 marks for the mammals surviving in cold conditions, it should be fine.
6)For the cornea one , thing is that everyone has similiar type of cornea and it doesn't have antigens. Think you had to write it doesn't have antigens first, and then explain that antibodies won't attack it.
7)Dunno about your yield answer, I wrote soil lacks minerals, and due to soil erosion.
8)For the blood clotting one you had to mention whatever you saw in the diagram, phagocytes, capillaries being damaged and a new one being formed to join the damaged ones, scab being formed, skin healing underneath, etc.

1) The one outside was plumule actually, cause plumule develop into baby shoots and shoots always grow first due to the consumption of their stored sucrose in the cotyledons.. The one inside was radicle..

LOL falluda memory xD
Yeah for that I just wrote effects of deforestation such as soil erosion, climate changes, destruction of animal habitats which could lead the to extinction of species. Some people in my class added that since only a small space of land would be left, all the animals would be forced to live in that small area of land increasing competition. I forgot to mention that.. but I wrote enough for the neccessary marks x)

Er, I'm not sure about that but it doesn't really matter for ME. I wrote embryo for one of em xD

Oh good that's what I wrote
Btw I think the one inside is plumule I'm pretty sure that's how it's given in my book

Er, I'm not sure about that but it doesn't really matter for ME. I wrote embryo for one of em xD
