Antihistamine drugs fall into two groups-those that block H 1 receptors and act mainly on blood vessels, and those that block H 2 receptors and act mainly on the secretion of acid in the stomach.
Biotechnology. Biotechnology, or genetic engineering, is the process of using living organisms to improve qualities of a plant by such as the plantâs ability to protect itself against damage or improving upon its ability to grow and produce.t allows for the transfer of one, or a few genes that can introduce traits such as better insect and weed control. Biotechnology at Monsanto Biotechnology is just one component of Monsantoâs three-pronged approach to delivering increased yields sustainably.
For example, one application of biotechnology is the directed use of organisms for the manufacture of organic products (examples include beer and milk products). Another example is using naturally present bacteria by the mining industry in bioleaching. White biotechnology, also known as industrial biotechnology, is biotechnology applied to industrial processes. 2  An example is the designing of an organism to produce a useful chemical.
