Critical concentration gradient model is helpful in understanding the mechanism of Z-ring formation. The distribution of positive and negative regulators of Z-ring formation in cell is not random but ...

In a ground-breaking study, researchers report a new technique that allows them to visualize the distribution of retinoic acid in a live zebrafish embryo, in real-time. This technique enabled them to ...

Deep Throat: “No, I have to do this my way. You tell me what you know, and I'll confirm. I'll keep you in the right direction if I can, but that's all. Just...follow the money.” Woodward, B. and ...

The surface flux of nitric oxide from a wheat field was investigated from 23 March to 29 May 1997 in the Kerzersmoos, Switzerland. A plot fertilised with 19 kg N ha⁻¹ in cattle slurry and 40 kg N ha⁻¹ ...

·The supply of hydrogen ions will also depend upon their concentration, i.e. the pH of the electrolyte. A concentration gradient in the electrolyte is illustrated. ·If the electrolyte is unstirred, ...

Diffusion is the movement of particles from a region where they are in high concentration to a region where they are in low concentration, and is one of the ways substances can move across the cell ...
