get A in all papers and you'll get an A*

you have to get high A's in 3 papers to get the star

I know someone who got 3 A's in all papers and got an A in the total
because his A's where low

high A means above the half of the marks to get A ??... or it have another calculations ?

The right answer is that muscles allow the villi to move around close in contact with the nutrients , this will reduce diffusion distance therefore increase rate of diffusion .
Does'nt make sense at all muscles are always thick, so they increase the distance, it has definitely to do with the contraction and transport. :)
the right answer is that the muscles help move the lymph in the lacteal since contractions of the muscles will squeeze the lymph (btw this is exactly the same like a question in June 2010 but in a different style !!!

how are you saying its prestalisis ,I think that lymph which is inside the villus (lacteal) only absorbs fatty acids and glycerol which were already digested in small intestine so I wrote it is for respiration to provide energy and for contraction and relaxation :D
and hey I heard about that
A-B=diif
A+diff=A*
dont you think it would be easier for them to write it in the grade therehold ,,instead of just "A* is not determined at a lvl of an individual component 8)
