An average 1,000-pound (450 kg) horse drinks 10 to 12 US gallons (38–45 L) of water per day, more in hot weather, when eating dry forage such as hay, or when consuming high levels of salt, potassium, and magnesium. Horses drink less water in cool weather or when on lush pasture, which has a higher water content
[3] [53] Cheese had typically been made using the enzyme complex rennet that had been extracted from cows' stomach lining. Scientists modified bacteria to produce chymosin, which was also able to clot milk, resulting in cheese curds. [54] The first genetically modified food approved for release was the Flavr Savr tomato in 1994. [4]
When complete, the list below will include all food plants native to the Americas (genera marked with a dagger † are endemic), regardless of when or where they were first used as a food source. For a list of food plants and other crops which were only introduced to Old World cultures as a result of the Columbian Exchange touched off by the ...
Of the 111 hectares of soybean grown worldwide in 2014, 82% was genetically modified in some way. Seventeen countries grew a total of 55.2 million hectares of genetically modified maize and fifteen grew 23.9 hectares of genetically modified cotton. Nine million hectares of genetically modified canola was grown with 8 million of those in Canada.
Some have criticized biofortification programs because they may encourage "further simplification of human diets and food systems", [20] because "[biofortification is] a strategy that aims to concentrate more nutrients in few staple foods [which] may contribute to further simplifying diets already overly dependent on a few carbohydrate staples."
Diamond v. Chakrabarty, 447 U.S. 303 (1980), was a United States Supreme Court case dealing with whether genetically modified organisms can be patented. [8] The Court held that a living, man-made micro-organism is patentable subject matter as a "manufacture" or "composition of matter" within the meaning of the Patent Act of 1952.
Genetically modified crops (GM crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering methods. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors.
Genetically modified plants have been engineered for scientific research, to create new colours in plants, deliver vaccines, and to create enhanced crops. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors .
