People! Need someone to explain Alleles in detail. Explain what Dominant/Recessive Alleles are . Also , especially , tell me what are homozygous and heterozygous phenotypes? I know what they are but cant understand how these are involved in Heredity.

SnowBrood, there is no such thing as copper deposit on the other side and the water level will rise. The answer is C. Electrolysis of Dilute Sulphuric acid ( water) . Because the ratio of Oxygen to Hydrogen is 1 : 2. Therefore you can actually see a obvious gap between two testtube. I hope my explaination is clear :D

No he is saying that if we use do CuSO4 electrolysis in this chamber the water level shud rise,he was not telling the answer he told the correct answer on the previous page !

I think you might want to ask some A levels people on the forum as i think im the only Bio guy here and i havent done that topic yet so if u need help quick u will have to ask them :p

what do u mean? it totally depends upon what are u trying to obtain, however u cannot react Potassium,Sodium and Calcium with Acid otherwise explosion might occur.
I wanted to ask if we can react a radioactive element like Francium with acids or not
cause our chemistry teacher said we cannot do reactions with radioactive elements :confused:o_O:unsure:

Ofcourse we can't. I mean Francium is HIGHLY reactive metal and reacting it with Acid can cause Major blast.
