same hereNot so clear, i dont think so.
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

Annotation is like label. here it is like "Label any two visible distinctive tissues" It meant one labelling for one tissue. it asked two. so only two labellings.Yeah I didn't know I was supposed to draw that hump hehe. I don't understand what's an annotation , it means four tissue layers? because it's written two annotations to describe two tissues! thanks a lot for your opinion
brother, why 2 x 2 in the e.g. you gave? i don't get it.See, it is hard to explain but imagine u had 2 aminoacid, lets call them Red and Blue
we can make
red red
red blue
blue blue
blue red
So as u see, 2 x 2....!!
Be carefull, be cause red blue....isnt like blue red
as they sed in the question..either end with amino group (-NH2) or a carboxyl group (-COOH)
As u saw in the example i gave 4 different compositions which is made from 2 since 2 x 2 gives 4brother, why 2 x 2 in the e.g. you gave? i don't get it.
This is an amazing explanation for oxidative phosphorylationasak
plz help me wid d foll.topics
oxidative phosphorylation,ethanol and lactate pathway
JazakallahThis is an amazing explanation for oxidative phosphorylation
watch all the different videos for the ATP really helpful
ethanol and lactate, i will look for it.
http://www.mediafire.com/?smfz60x62dw4by5Any One Having AS biology Notes Full AS Syllabus Comprehensive but summarized Form?
yeah got it thanksAs u saw in the example i gave 4 different compositions which is made from 2 since 2 x 2 gives 4
and if we started with 3 aminoacid we wud get 9... 3 x 3
and so with 20 aminoacid we will get 400
I hope u got my point.
A sequence of amino-acids end in either an amino group (-NH2) or a carboxyl group (-COOH) . What is the theoretical number of chemically different dipeptides that may be assembled from 20 different amino acids?
A-40
B-80
C-160
D-400
an annotation is a step further than the labelling i.e. it is a small description.Yeah I didn't know I was supposed to draw that hump hehe. I don't understand what's an annotation , it means four tissue layers? because it's written two annotations to describe two tissues! thanks a lot for your opinion
it will be the same way you wud perform any other chromatography... as we studied in o levels too :how to separate chloroplast pigments using chromatography... helppp!!!
Thanks in advance
I heard that too, usually if coloured picture, we could even say as an example, xylem darker, phloem lighter in colour.an annotation is a step further than the labelling i.e. it is a small description.
normally when we are asked to annotate its mostly for xylem and phloem
like you write that it is an alternately arranged tissue and about its size and stuff that you can SEE.
If its not right then plz correct me here
yeah u r ryt. u can write that too. pretty much any visual description is acceptable.I heard that too, usually if coloured picture, we could even say as an example, xylem darker, phloem lighter in colour.
I am not sure though.
I read the marking scheme and it's written one correct labeling from: then they included cortex XSsame here
Have a look at the examiners report too.I read the marking scheme and it's written one correct labeling from: then they included cortex XS
I deleted my other post, because i think i did it wrong. Look at the reaction from the one top to the one below....this is the fragmentation occurring.There is a question in the pastpapers that says an enzyme will hydrolyze the hinge region of antibodies and break the antibodies into "3" fragments. How can they break into 3????? Shouldn't the antibodies break into 2 parts each contains one heavy chain and one light chain if hydrolysis occurs at the hinge region??
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
