  2. Salt water dimmer - Wikipedia

    en.wikipedia.org/wiki/Salt_water_dimmer

    [4] [5] [6] The brightness also depended on the concentration of salt in the water. [4] The switchboard built at Her Majesty's Theatre, London in 1897 had a dimmer scale of 0 to 10, whereas gas lighting only had 3 levels. [1] The salt water need to be refilled regularly, the metal electrodes corroded, and the dimmers emitted a strong smell.

  3. Crassulacean acid metabolism - Wikipedia

    en.wikipedia.org/wiki/Crassulacean_acid_metabolism

    Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.

  4. Calvin cycle - Wikipedia

    en.wikipedia.org/wiki/Calvin_cycle

    The Calvin cycle, light-independent reactions, bio synthetic phase, dark reactions, or photosynthetic carbon reduction (PCR) cycle [1] of photosynthesis is a series of chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose.

  5. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    These include the amount of light available, the amount of leaf area a plant has to capture light (shading by other plants is a major limitation of photosynthesis), the rate at which carbon dioxide can be supplied to the chloroplasts to support photosynthesis, the availability of water, and the availability of suitable temperatures for carrying ...

  6. Anoxygenic photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Anoxygenic_photosynthesis

    Anoxygenic photosynthesis is a special form of photosynthesis used by some bacteria and archaea, which differs from the better known oxygenic photosynthesis in plants in the reductant used (e.g. hydrogen sulfide instead of water) and the byproduct generated (e.g. elemental sulfur instead of molecular oxygen).

  7. Photic zone - Wikipedia

    en.wikipedia.org/wiki/Photic_zone

    The photic zone (or euphotic zone, epipelagic zone, or sunlight zone) is the uppermost layer of a body of water that receives sunlight, allowing phytoplankton to perform photosynthesis. It undergoes a series of physical, chemical, and biological processes that supply nutrients into the upper water column .

    Cowlick vs. Balding: Key Differences. A cowlick differs from a bald spot in a couple key ways.. First, a cowlick is a natural, normal feature of your scalp that occurs as a result of your genes.

  9. Photosystem II - Wikipedia

    en.wikipedia.org/wiki/Photosystem_II

    Photosystem II (or water-plastoquinone oxidoreductase) is the first protein complex in the light-dependent reactions of oxygenic photosynthesis. It is located in the thylakoid membrane of plants , algae , and cyanobacteria .
