shake some of the test sample with about 4 cm³ of ethanol. Decant the liquid into a test tube of water, leaving any undissolved substances behind. If there are lipids dissolved in the ethanol, they will precipitate in the water, forming a cloudy white emulsion. THis can be explained using the partition Law ! lipid is more soluble in ethanol because they form hydropic interaction !

As we know that neurones acquire myelin sheath to conduct electric impulse! But why only neurone contains Schcwann cell that grows to form the sheath wheras other cells donnot have it ???

Abscisic helps in closure of stomata !! But how does it works (mechanism involve Ca 2+) ?? I got a lot of different explanations !!!!

Maybe u can mix some glucose powder in to a cup of water to make a glucose solution . theres a drop in temperature of the solution !!!! And u can seperate the both solution by distallation !!! 9 (but i havent try it )

u can do some home xperiment if u are interested !!!! the most popular home experiments is Esterification !!!!! try iT , u'll like IT

Tru Arrhenius Equation !!!! ln k = -Ea/Rt + ln A But the problem is the value of Arrhenius constant !!!

ganglia ?? Do u mean the swelling part ??? All neurones from the CNS are motor neurones (efferent neurone).. So . the motor neurones do not pass through the ganglia ( observed from cross section of spinal cord ) ??!?!!
