It depends ! I don't think there's some specific *website* or source where you can get them from ! There might be but all i can say is memorise/ keep in mind their identifying features e.g. artery's walls are thick and vein's one are thin !! That'll help you to identify the organs !!SHUBHAsnlnm said:can you provide the images of the slides that come in the cie exams ie:

lindalinoo said:another question ..
active yeast is placed in a test tube and connected by a delivery tube to a second test tube containing hydrogencarbonate indicator
the color of the indicator was red at the begining but after 15 min's it turns to yellow .. can anyone explain the reason for this change??
i know that hydrogencarbonate is red in neutral, purple in alkaline and yellow in acidic solution .. and yeast is a catalase
how does it change the color of the indicator to yellow?? :unknown:
i'll be glade if i got the answer
my regard
How so? Wouldn't heat be needed by to convert water into water vapour???? So wouldn't it be an endothermic reaction?Ghalya001 said:Endothermic i guess!
oh thats what i wanted to make sureee .. thanksEasyyyyy
u shud know that CO2 is acidic and in respiration of yeast it gives out CO2 so it will turn hydrogen carbonate yellow simple !
