Biology Questions

[emi]

for now i have 2 Questions from past papers .

O/N 04 paper 6  page 2
i;ve always had problems with solving Questions like these , calculating actual size and stuff

if any one could tell me how to do Q1 part a)  (i) & (ii)

Another Question i wanted ask was , in may/june 2008  in the last page
the Question where we had to name the parts of the kidney something and its function .
that kind of Question and diagram i never saw it or studied it in any of my biology books

i have these books for bio
1)  IGCSE study guide for biology   ( by Dave hayward )
2) Igcse Biology (by Mary Jones)

BUT i did find it in my GCSE books
1) GCSE Biology by B.S Becketts PG 113-115  ( this is the best book its soo detailed and nice  but im afraid it got things that are not in out syllabus so i dnt rly know wat to study )
2)GCSE biology by D.G mackean


so i was wondering why its not in the IGCSE books while it is in GCSE books ?

Its so easy its in the syllabus. Our then if you find it difficult use the IGCSE Letts revision guide its the best.
Note: the glomerulus is for filtration, the bowmans capsule is for absorption and the collecting duct is to pass the urine to the pelvis.

how do i prepare for my biology paper 1 (multiple choice)
please help

[saifalan]

U will have to read ur books clean and thorough. Do as much past papers as u can, as questions can be repeated.

[SGVaibhav]

how much do we have to get in paper 1, to get an A+?
i heard it is an constant value,
i heard we have to get minimum 36 to get an A+
and my other teacher told me, full to get an A+.

isnt it hard to get full?
i mean, some things always go wrong.

[emi]

and no one answers my Questions .. hmph ~~~
guess i have to find another way to get that

[SGVaibhav]

i have not even solved one paper 6 in my life so i cant do that.
sry
  .

but i can explain the kidney thingy.
and how it works.
the biology by DG Mackean  is very good for that part.
just learn even though if there is something extra


the capillary is called a glomerulus  ( oh no i forgot spell)

so high pressure over there causes the contents to leak out into that tubule.
but only small things go out, such as glucose, water amino acids ... (if protein and all that goes out, then the kidney is malfunctioning i.e ther is a problem)
this part is called ultra filtration

now these substances travel down the tubule
and few substances get absorbed back into the blood, to adjust the blood concentration/
this is called selective reabsorbtion.
it is called bowmans capsule  ( i think i spelt it right).

now the these substances travels down the renal tubule, collects in one place, pelvis and passes on to ureter

U can also follow Olevel Federal Biology, written by some Chinese dudes (Srry forgot their names). Its a very good book and helped me the most to score an A.

I study from both GCSE and IGCSE Books,
this is better, I think

"better safe than sorry!"

[astarmathsandphysics]

And gcse books are easier to find. Or maybe that is because I am in England, where everyone does GCSEs.

[MissDE]

It's easier everywhere astarmathsandphysics!
