i wasnt just rolling on the floor i even laughed my a** off!!i know dah waz fuuny ...but you dont have to roll on the floor!! (/-_·)/D·····------ -> (;/'o')/....
thnx dude u really helped me!!!2) enzyme breaks down insolube protein and fat into smaller and solube amino acids and fatty acids thus removing stains
3) platelets supply thrombokinase which converts prothrombin to thrombin which activates fibrinogen to fibrin. This forms a mesh which traps blood cells and becomes a clot preventing the entry of bacteria. the clot dries and hardens to form a scab, which covers the wound until the skin beneath has repaired.
Guys need help is it necessary to do yearly past papers ....
P.S i have done all topical 1998-09 ......
thnx...well, for the 1st question i guess enzyme is obtained from bacteria in da same way as insulin is obtained
Bacteria such as fungi or algea are inserted in fermenter and feedstock such as glucose , amino acid , sucrose are inserted to be a source of food for them , then they r left for a time for the bacteria to reproduce more and to produce more enzymes in their cells , Then if the enzymes are extracellular they are extrected directly from the filterate , if they are intercellular they are seperated from the feedstock and crushed to be seprated with any solvent such as water
(do correct me if m wrong)

Can someone please help me with Q# 27 & 38?
Thanks

Can someone please help me with Q# 27 & 38?
Thanks
no 27 is C, but ur right about 3827 : B
38 : C
first you say black is dominant and then you say that the one in white is heterozygous??27) its C, becauseair goes out from top(X) and all antibiotics are collected at bottom (Z)
38) its D, since at A * B the black dominated, and at B * C black went came from both(both homo, so we r only left with D
some more questions!!!
1) Describe what happens to amino acid inside liver cells....
2) The Carbon dioxide concentration in the atmosphere has increased significantly over the past 150 years. Explain why this happened???
3) Describe two reasons why animals kept in sheds gain weight faster than those kept outside...
thnx in advance....
hmm ok....not good at biotech me..no 27 is C, but ur right about 38
1) amino acids are used in cells for bulding up proteins as the cells grow, and also for making enzymes. They are never stored, the excess amino acids are broken down by the process of Deaminiationsome more questions!!!

2) deforestation, co2 released by combustion, by respiration of animals. Less plants to absorb this CO2, thus increasing its concentration in atmosphere.
3) 1.less loss of sweat
2. i dont know
Can you please Explain again? Shouldn't it be B or something? Thnx in advance again to spidey and snoo!27 : B
