Nonpoint source water pollution regulations in the United States The primary nutrients found in water due to nonpoint source pollution are nitrogen and phosphorus from fertilizers. An influx of these nutrients can lead to eutrophication within the water. This is when there is an excess of nutrients in water, thus leading to an explosion in the growth of algae. The algae can cover the lake and block sunlight from reaching the organisms below, typically killing them. NPS water pollution is regulated at the federal, state, and local level. Yet, the pollution persists and remains a significant problem. There are a number of reasons why current regulations have failed to
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
