One of the primary advantages of cell culture is the ability to isolate a single type of cell from a multicellular organism. How has this advance changed the study of biology?

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

the correct answers are;

a. the rock was made from more than one type of material.

e. layers of hot liquids in the rock cooled and solidified at different temperatures.

these are the two options that are related to the statement given above.

well this my answer.

releases oxygen is a light-independent reaction and so is (fixes carbon dioxide. light-dependent reaction takes place in the stroma and lights dependent reaction take place in the grana, light-dependent reactions produce atp. and last but not least, light dependent reactions produces glucose.

hope it : )
