Environmental impacts of increased protein consumption
Explanation:
Protein is a major macronutrient that helps in body building and present more in animal sources. Hence increase in population raises the demand for more protein based foods. So, there is a huge increase in animal farming.
Animal farming directly impacts the environment as it is one of the major causes of global warming and environmental pollution.
Grazing is a common feeding method for farming animals and this reduces the greenery of vast lands which can store more carbon. Thereby these animals affect the carbon footprint.
Next, farm animals release a lot of methane in their waste products. Methane is one of the major greenhouse gases and increases global warming.
Moreover, animal waste effluents pollute the surrounding natural land and water sources with contaminants including harmful pathogens.
The correct answer is:
fixation
Explanation:
Nitrogen fixation is a method by which nitrogen in the Earth's atmosphere is converted into ammonia or other molecules prepared to living organisms. Nitrogen fixation is carried by a diversity of bacteria, both as free-living organisms and in symbiotic association with plants. Because it is the primary source of the nitrogen in the soil, nitrogen that plants need to grow, nitrogen fixation is one of the most critical biochemical processes on Earth
Answer:
luminosity is the amount of electromagnetic power emitted per unit of time by a star
Two potential functions that eukaryotic cells perform to regulate transcription are DNA methylation: a process of epigenetics that participates in the regulation of the gene expression in two ways, directly impeding the union of the transcription factors, and indirectly propitiating the closed structure of the chromatin, and Histone acetylation, enzymes that acetylate conserved lysine residues in histones by transferring an acetyl group from an acetyl-CoA molecule, to form ε-N-acetyl lysine, is extensively associated with an open chromatin structure and therefore accessible to transcription factors, which increases gene expression.
