can someone please explain the following : 
You're sayying exactly the opposite thing bro :/ In the book its written clearly that facilitated diffusion takes place across channel proteins and active transport thru carrier proteins.:/
Q20:-(D)
Wait but you're getting the answer only by adding the last 3 values in the table.You dont need to add the first 3 and subtract from the totalQ20:-(D)
It says Used in Photosynthesis (used by Plants)
The first three are Not Used By plants.. SO just add them up and Substract From total.! Which ends up to Be 23 500J!
If u Need Detailed Explanation do Tell Me!

!!Q24: 40 Units on Eyepeice cover 1 unit on Micrometer which is equal to 0.1mm or 100 micrometer.Hello
How to solve q 24 and 40 !
And why q38 ans should be A not B ?!
http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Biology (9700)/9700_w10_qp_13.pdf
!
Yeh theres logic in adding the bottom 3 too.Photosynthesis is the process whereby light energy is converted to chemical energy.so u can see that the bottom 3 processes are converting chemical energy to other forms.So youll add them up to get the chemical energy.Okay.. I wanted to Look More logical
Why didnt You Think of This Before Asking the Question
!
Acha tell me how does the casparian strip help with generation of root pressure ?Why didnt You Think of This Before Asking the Question
Look.First the total energy content of Kelp consumed i.e by all organisms will be determined.And then the energy content of Kelp consumed only by sea urchins will be determined.So the Percentage of energy transfer can be calculated by (Energy content of kelps consumed by urchins/energy content of kelp consumed by all organisms) multiplied by 100%.I hope you understand
Root pressure is built up due to osmosis s dthe difference in water potential. So you basically explain how water moves through the symbolist route in the endodermis and how it leaves the previous cells it moved through(including the root hair cells) having a lower water potential, so water moves from the soil into the root because of the difference in root pressure
Thank you soooooo muchQ24: 40 Units on Eyepeice cover 1 unit on Micrometer which is equal to 0.1mm or 100 micrometer.
Not it asks for 10 micrometer.. simply use ratios..
40 : 100
X : 10
X= 4 (ans is B).
Q40: Multiply all Three Values for Given Specie... Then You end up With B
Q38) So You understand Sun to Plants is Least.. so ans is A or B
In A it says Decomposers would get 2nd Least amount of energy which is True
Because There is Too Much energy lost in respiration of Producer+Primary+Secondary consumer.
Hence Least Energy remains For Decomposers..!
Hope I Helped
q14 1 is correct as you will be able to thee the tail and Head
just an example)
q14 1 is correct as you will be able to thee the tail and Head
2 the arrangement can be seen (its like you cut a human body in half you will be able to see where the stomach is
3 length :/ it doesn't show anything about strength 'you can't see strength'
q20 whats the confusion here? can you let me know so i can explain better
q30 there is no Hemoglobin in plasma its only present in RBC so no carbaminohaemoglobin
what? i dint get it :/
