Young–Helmholz Theory of Trichromatic Colour Vision is explained by three colour opsins present in the cone cells: Red/Long on the distal end (telomere) of the X-chromosome, Green/Medium also on X and the Blue Short on chromosome 7. Before the rise of oxygen-producing bacteria, 3750–2500...
"Some of the dominant colors seen in aurorae are red, a hue produced by the nitrogen molecules, and green, which is produced by oxygen molecules." Teet continued. Image 1 of 4 The northern lights illuminate the night sky over a camper's tent north of San Francisco in Middletown, Californi...
Blood (and tissue) changes color depending on how long it has been exposed to air. Learn the meaning of red, brown, black, pink, or gray period blood.

The aurora occurs so high up that the mix of air we are familiar with is not the same as at 100 km. The atmosphere there is much less dense, and stratified by gravity into layers. The nitrogen layer lies above the oxygen layer. What's the rarest aurora color? It's hard to say bec...
The chemical reaction often relies on a pigment called chlorophyll, which gives plants their green color. Photosynthesis is also the reason our planet is blanketed in an oxygen-rich atmosphere. Types of photosynthetic processes There are two types of photosynthesis: oxygenic and anoxygenic. They ...
