in physics sec B question 1....right? that would be right, narrower tube would have worked, perhaps more air in the container too. (i did not attempt the question)

What is continuous/discontinuous variation?
I hope u already know what variation is... so in continuous variation, a characteristic in a person(mostly relating to phenotype) can vary over a long range(like skin colors can be pale, pink, light brown, dark brown or any intermediate colors.....
Where as in discontinuous variation, the characteristic(mostly phenotype) can only be a few options and cannot vary(in a range)..... like your ear lobe can be joined or not.... only these two possibilities exist, n there is no intermediate state!!!

continious variation is effected by environment while discontinuous is not e.g blood group cant be effected by th environment but skin colour is
