comment What is optical density in Lowry's protein estimation method?
You can think of the blank as a way of calibrating the instrument. The blank defines the amount of light that will hit the photodetector when there is none of the species of interest in the cuvette. By setting this as the zero you have prepared the instrument for measuring the samples of interest.

comment Can animals make their own unsaturated fatty acids?
@biogirl Yes, the unsaturated fatty acids will be incorporated into new phospholipids at the endoplasmic reticulum then transported in vesicles to the plasma membrane.

comment How are two species with similar phenotypes identified as different?
@GriffinEvo Yes, but is a concept of species based upon ability to interbreed of any use when dealing with bacteria?

comment Name of scientist who discovered lifesaving drug and chose not to patent it?
It's just possible that you are thinking of the failure to patent hybridoma technology. Georges Kohler and Cesar Milstein developed this at the MRC lab in Cambridge, and won a Nobel prize. Milstein was probably philosophically opposed to patenting, but the failure to do so was essentially a bureaucratic decision. It's an interesting story.
