Oxygen releases oxygen into the atmosphere, while respiration, decay, and combustion remove it from the atmosphere. In the present equilibrium, production and consumption occur at the same rate. Free oxygen also occurs in solution in the world's water bodies. The increased solubility of at lower temperatures (see Physical properties) has important implications for ocean life, as polar oceans support a much higher density of life due to their higher oxygen content. Water polluted with plant nutrients such as nitrates or phosphates may stimulate growth of algae by a process called eutrophication and the decay of these organisms and other biomaterials may
Epigenetics of plant growth and development or other component of DNA. Long non-coding RNA often complement functional regions of DNA with overlaps or antisense (Kung et al. 2013). To direct transcriptional silencing, a non-coding RNA will associate with a polycomb group protein which to tether it to a specific gene for silencing (Kleinmanns et al. 2014). Germination is the early growth of a plant from a seed. Meanwhile, dormancy precedes germination and serves to preserve a seed until conditions are receptive towards growth. The transition from dormancy to germination seems to depend on the removal of factors inhibiting growth. There are many models for germination which
