    bcoz when carbon dioxide is released, it is absorbed immediately.. i will give you an example...for instance there is no soda lime...and nothing is present to absorb carbon dioxide..you put for exaple 10cm3 oh CO2 the level will drop bcoz there is more gas! now remove the 10cm3 of CO2 the...

    the not noticable..cuz only i guss 0.04% is CO2, in air (correct me if m wrong) basically i mean only a lil amount of CO2 is in air...so it won't be noticeable.

    there is a gas in the lil tube (where colored water is there) when you take out the gas water ill automatically come up due to more pressure... the gas in this case is oxygen...whn you are taking it out (seeds are using it) the level rises... if you still don't get it then please don't...

    yeah...air is in the tube where colored water is there....BUT the soda lime absorbs ALL the co2 in the air and therefore there is ONLY oxygen remaining...get it?

    the test tubes are closed...therefore CO2 of atmospher doesn't matter!

    the thing is that...in respiration it releases CO2 which is absorbed by the soda lime, immediately so no 'exchange' of gases takes place...causing the level to stay in the same position! but here...it is using up oxygen that's why level is rising! don't mean to offend you btw... :oops:

    Assalam-o-alaikum wr wb... for the 19th one...the level rises bcoz the germinating seeds take in Oxygen...as the gas decreases in the tube the level of X rises... but the dead cells don't need Oxygen so the level remains the same... hope you get it :)

    NEED HELP WITH BIOLOGY PAPER 1

    Assalamoalaikum wr wb! We surely CAN detect pain in our eyes and brain.. For instance when something goes in our eyes don't we know about it? We do cuz it hurts! Same thing is with the brain..we can sense pain (like see people who have brain tumor) but the thing is that we know on one side...

    Urgent doubts for bio p1,pls help!!!!

    Assalamoalaikum wr wb! An artery is an organ made up of many different tissues... And the removal of carbon dioxide is excretion..respiration doesn't "remove" carbon dioxide..it gives it out, instead! So the ms is right..:)

    Assalamoalaikum wr wb! Bb is for children...not their parents..mother is golden which means must be homozygous recessive and when the chlod is black it means that one recessive allele must be present in him/her Hope It clears your doubt! :)
