Re: The most boring tasks in Biology

... using a hemocytometer on a fluorescent microscope was boring. I was measuring the change in photosynthetic characteristics after changes in illumination at different iron concentrations. This involved lots of time points where I needed the cell density in the culture, so I spent many many ...

Photosynthesis/carbon fixing

... stages involved, I cannot seem to get to grips with the graphs in this question. There are three graphs. In all the graphs the oxygen levels, illumination and temperature are constant. The only variation is the level of the enzyme rubisco carboxylase which is set at normal for the first graph, ...

... vision: cave fish with induced eyes do not respond to light. Both the eyeless epigean fish and cave fish with induced eyes are indifferent to the illumination whereas the surface forms are scotophilic, suggesting that optic development and phototactic behavior are decoupled. So despite the passing ...

This is beyond ridiculous. So this kind of shoddy 'experimental results' cast more than a shadow of doubt on all ...
