A genetically modified organism (GMO), also known as a transgenic organism, is any organism whose genetic material has been altered using genetic engineering techniques (i.e. genetically engineered organism).enetically modified crops (GM crops, or biotech crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering techniques. In most cases the aim is to introduce a new trait to the plant which does not occur naturally in the species.
A hard disk drive (sometimes abbreviated as Hard drive, HD, or HDD) is a non-volatile memory hardware device that permanently stores and retrieves information. There are many variations, but their sizes are generally 3.5 and 2.5 for desktop and laptop computers respectively.
Hydrotreating, formally known as hydrodesulfurization (HDS), is a chemical process used on natural gas and refined petroleum. The aim of this process is to decrease the amount of sulfur in the petroleum by increasing the amount of hydrogen in the product.d. In hydrotreating, hydrogen is introduced into a mixture to increase the overall hydrogen count. Petroleum undergoes what is specifically called hydrogenolysis. This is when the carbon and sulfur bond contained within petroleum is split, and a hydrogen atom is linked to both the carbon and the sulfur atom.
