the higher the temp the more pigment comes out
except for zero, i dunno why tho
yep and at 70 degrees the pigment is destroyed or all the pigment has gone out aand not a lot left so a very small amount of pigment comes out

correct me if im wrong tho :/


and tell mee Psyclax
what did u study
like just the core practicals?


at 0 and below it means the channel and carrier proteins are denatured therefore they cannot control what goes in and out and alot of pigment leaks out
also ice my pierce the surface of the membrane, so theres hole and alot of pigment leaks out :)

@ Damlaj and ksitna
it was easy, there was THIS ONE QUESTION i was about to tear the paper BECAUSE OF IT
the organic question about moles..the first one! about 0.125 moles of whatever to 0.100 moles of whatever
what was that about?!! ugh 2 marks definitely off :(
but apart from that..i found it smooth!!
