Photosystem i requires light of minimum wavelength 700 nm while photosystem ii requires light of minimum wavelength 680 nm. this difference indicates that photosystem i requires energy to function than photosystem ii. this is because light of wavelength contains more energetic photons than light of wavelength.

Of seawater increases with decrease in the temperature. therefore, the cold water sinks to the deeper layers at the bottom

Membrane vesicles containing an internal sodium chloride (nacl) concentration of 0.14 m are placed into separate beakers each containing a different solution. the first beaker contains 0.14 m sucrose, while the second beaker contains 0.14 m calcium chloride (cacl2). the temperature is 25°c. what is the solute potential inside the vesicles, expressed in units of mpa?
