--- Quote from: SNA on June 07, 2010, 09:06:08 pm ---i think the answer is B.this is how i think would be the reason. for P, the liquid moves to the left as soda lime adsorbs the co2 which lowers air pressure in test tube. thus, higher air pressure outside tube pushes liquid towards the test tube. for Q,air pressure inside test tube and outside is the same,so the liquid stays at the same place.the glass beads did not effect the experiment.

Yes & No for the first part True but 4 the 2nd Co2 is released but not absorbed u would assume that it would move to the right but NO because dnt 4get oxygen is absorbed :)
Hope tht helped!

conduction and support. conduction is like transport of water and mineral ions.
support is because, w/o water the plant will wilt. with water, the plant is like fresh and straight etc

;D that was what i meant by air pressure in test tube stays the same as carbon dioxide released but O2 absorbed. but you explained it better. thank you! ;)

Ok Thanks kstina and SNA, :D
i was like absorbtion :P
