37 in june 2010: D, because it's the only pyramid that is increasing suddenly after age 40 so it will have the most increase around age 60.

28 in 2009 : 1 is dry so it cannot be it, germination requires water., 2 is correct because it has water, oxygen and the seeds. 3 Is incorrect, oxygen is absorbed.. and 5 is cold which is wrong, germination needs a temp of 20-25 for optimum growth. So it's 2 and 4, So C.

2008:
8)A, Respiration releases Energy always and Co2 ofcourse. Just not oxygen since it's used to respire.
14)Transporting oxygen is haemoglobin, meaning red blood cells and to produce hameoglobin, you need iron, So in the iron graph. Most is eggs, Aka B.
18)D, because lungs get two blood transportation at once, One from the heart with de-oxygenated blood and one to the heart which is oxygenated.
33)B and D are cancelled immediately because they have photosynthesis so you have A and C left. You would go C because it has respiration and all living organims respire.

please say 2007 also!!!

3)B, Binomial system begins with Genus in Capital first letter and second is species, not capital.
15)The small intestines are after the stomach, so starts from 1 and ends at 7 so 6cm, B
27)B, This you must use the circle to understand, breaking starts when these little curves show from 26-27 and 6-25 it thickens become stronger.
32)D, This you must do all possibilities in your head or on paper to see which will bring what they asked for.
34)C, because they come after the producers.
38)B, keeps increasing so nothing is limited, everything available.

2007:
3) IT is B becoz it said binomial system so u must know it consist of two part (genus and species)
the better way is that choose the one only with two word, the first letter of the first word must be in capital
and the second all in small

15) count from 1 to 7 and ull end up getting 6. (count from the starting of the point to he point on the anus)

27) B is the answer becoz from the graph if u dont memorize the cycle. in the first few day the lining ids shedding of
so it must be bleeding and when the thickness start to break it is on thee 26 day and eventually the last one
will be that in 6 day the uterus is thicken.(u can judge from the diagram if u dont know )

32) D bocoz if the dominant (aka red) and recessive (aka white) and the off spring are equal half red and half white
that mean that the red have a recessive allele in it. and tha white is recessive so it shud alwayz contain rr
while red can contain Rr or RR but it said half red and half white so the answer is Rr.

34) C becoz D is always producers (aka green plant) so whenever u see green plant the next is the herbivore.

38) it is B becoz it said no limiting factor so there is plenty of food etc. so the population will definitely increase
so it didnt say that it will decrease soD is out and A and C tell us that is will eventually stop but it shudnt coz they said
no limiting factor.

just log on to clear ur doubt
hope u got it

isn't the black object the nucleus???????????????????????????????/ :%)

q4 2010 november plzzzzzzzzzzzzzzzzzzzzzzzzzzz http://www.xtremepapers.me/CIE/Cambridg ... _qp_11.pdf
isn't the black object the nucleus???????????????????????????????/ :%)

they are asking the incorrect label
and the black one is chloroplast it cant be a nucleus coz a cell cant contain two nucleus
the stomata, cell wall and cytoplasm is correct
but the line of the cell way is wrong it must be the line after it

hope u got it

Hello, my friends!!! i want to know that the CIE only ask biology from the syllabus.. If yes, when i look at the 0610 biology syllabus for year 2010, i didnt find the meaning of "involuntary action" ,but it did ask in the exam. So, how??? can anyone help me on this???? Not only that, i want to know if i want to get A*, what is the minimum marks i must get for paper 1,3, and 6???

 

[CaptainDanger]

Each and every word of it is not mentioned in the Syllabus... For the involuntary action, nervous system must be mentioned in the syllabus and reflex action too which comes in involuntary actions... The book gives further detail which can come... And your grade depends on the grade threshold of the specific session... I am not an IGCSE student so no idea about the numbers.... Though past year thresh holds can give you the idea about it...
