Because it was the control. Note how all other cuvettes had DPIP. We did not really know what dpip's effect on the % light transmittance was, by adding a ontrol, we could not compare and contrast.
1: control, recalibirate spectrophotometer 2: photosynthesis does not occur without light 3: photosynthesis does occur with light and live chloroplasts 4: boiling chloroplasts=no photosynthesis 5. control

there wasnt 1 there really wasnt 1. they just fought
no it wasnt.
e-value of an optical brightening agent is the absorbance value obtained (in the UV region), when the absorbance of 1% solution is measured using a cuvette of 1 cm path length. T.J.R.PILLAI
no he wasnt xx
there wasnt even 1
no, he wasnt in power until 1933.
no because sonic cd wasnt made then
she wasnt just famous for 1 she was famous for lots
yes there were but it wasnt deleware at the time all the continets were actually 1
The Beer-Lambert Law:A = epsilon*b*cA is absorbance (unitless)epsilon is the extinction coefficient at a particular wavelength (L cm-1 mol-1)b is the path length of the cuvette (cm)c is the concentration of the solution (mol/L)
