When encountering another vessel in darkness or reduced visibility, what is indicated by the presence of only a visible white li
katrin2010 [14]
The vessels use three main colors (white, green and red) where each color alone, combination of two colors as well as the three colors together each has a certain meaning. This meaning is sort of an international code that is agreed all over the globe.

So, based on this code, the presence of only visible white light means that your vessel might be overtaking another vessel. In this case, you should give way to either sides. The other vessel should standby until an action is taken from your end.

Why more atp is produced in aerobic respiration than in anaerobic respiration
Oxana [17]
Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. This works by the energy released in the consumption of pyruvate being used to create a chemiosmotic potential by pumping protons across a membrane. 

<span>Aerobic metabolism is 19 times more efficient than anaerobic metabolism (which yields 2 mol ATP per 1 mol glucose). They share the initial pathway of glycolysis but aerobic metabolism continues with the Krebs cycle and oxidative phosphorylation. The post glycolytic reactions take place in the mitochondria in eukaryotic cells, and in the cytoplasm in prokaryotic cells.</span>
