Spatial Data Objects. The geometry and geography data types support sixteen spatial data objects, or instance types. However, only eleven of these instance types are instantiable; you can create and work with these instances (or instantiate them) in a database.
Rewiring the grain. Metabolic engineering. Golden Rice technology is based on the simple principle that rice plants possess the whole machinery to synthesise Î²-carotene, and while this machinery is fully active in leaves, parts of it are turned off in the grain.
Some genetically modified foods are designed to improve nutrition, quality and taste. For example, potatoes are modified to even out distribution of starches, enhance texture and reduce fat absorption.Genetically modified golden rice has more beta-carotene and iron that consumers in malnourished populations need.utrition and Safety Concerns. Despite added nutrition values, there are concerns about genetically modified foods. The alteration of certain nutrients can lead to unexpected changes in a food's other nutrients, according to the Food and Agriculture Organization of the United Nations.
