It is molecular pathways through which a cell senses changes in its external or internal environment and changes its pattern of gene expression or enzyme activity in response.

Plant molecular farming is the growing of plants in agriculture to produce pharmaceutical or industrial
compounds instead of food, feed, or fibre. The possibilities range from the manufacture of medical
products, such as pharmaceuticals (drugs) and vaccines, to the production of products like biodegradable plastics and industrial chemicals.

Alternate Answer:
There are lots of people I admire for different reasons - they include: Johnny Depp for his acting, Germaine Greer for her honesty and original thinking, Nelson Mandela for his bravery....

At the moment I most admire Al Gore because of his strong beliefs and conviction - especially about Global Warming. We need a clear leader on this and for me he is doing a great job.

Alternate Answer:
I admire my parents. Because they do a lot of great things and really look out for me, and they're not plastic like some celebrities.
I know what they've been through, and I know it's tough, and yet they still do what they do best. I really respect and admire them for that.

While screening tests are very accurate and reliable tests, they are not 100% accurate. Samples which screen positive are presumed to be actually positive, but the specific drug must be confirmed by a more specific method. The method employed by the Toxicology Section for all confirmations is gas chromatography/mass spectrometry (GC/MS).

In confirmatory tests, a procedure specific to the class or family of drug for which the sample screened positive is employed to "wash" or separate the drug itself from the matrix, i.e. blood or urine, in which it resides. The procedure of separating the drug from the sample is called an extraction. The Toxicology Section has different procedures for each class of drug. The general scheme of an extraction is to adjust the pH of the sample, expose the sample to an organic solvent to wash out the drug, collect and concentrate the organic solvent, and derivatize the drug in the sample. Some extractions have a but a few steps in the scheme, while others have many steps. The extraction process is one of the most time-consuming aspects of drug testing.
