Amicroscope technique that will not allow one to see specific parts of living specimen is

a) using stain under a light microscope

b) using a scanning electron microscope

c) passing light from a microscope through a pinhole

d) using a fluorescent substance with a specimen under a light microscope

i know that sometimes with using a stain the specimen can be killed, but im not sure if thats always the case. in advance for your

plants absorb water from the soil by osmosis. root hair cells are adapted for this by having a large surface area to speed up osmosis. the absorbed water is transported through the roots to the rest of the plant where it is used for different purposes: it transports dissolved minerals around the plant.

energy per photon is e = h*c / λ  

e = 6.63*10^-34 * 3*10^8 / 6*10^-7 j = 3.315*10^-19 j  

nr. of photons = 10j / 3.315*10 = ^-19 j per photon = 3.02*10^19 photons
