The influence of area on the number of species

... examples, if you look at the diversity on oceanic islands, such as the Hawaii or the Pacific islands, they are still very diverse and have high concentrations of species in small areas. When you go onto continents, the diversity doesn't increase linearly with area because many of the habitats ...

Re: The most boring tasks in Biology

... 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 sessions over a period of many ...

Increase in free energy in glycolysis

... and actual Gibbs energy. The other reactions are close to equilibrium (thus they can be used by gluconeogenesis as well) and only the actual concentrations of the substrates/products determine which way it will go.
