1. The enzyme Esterase-5 has been extracted and purified from a number of supposedly closely related fruit fly (Drosophila) species. These have been run under gel electrophoresis, to separate by overall charge. The distances the protein dots have moved down the gel are shown below. Show these data graphically. (Hint- are these discrete or continuous variables?)

Drosophila species Distance From origin to protein spot(s) mm

Hi, I'm just wondering if chlorophyll b is an accessory pigment and does not transfer the energy of light to the carbon fixation reactions of photosynthesis, what is its functions?
