What is BT cotton?
BT cotton is geneticly modified to contain a natural toxin created by a bacteria whos initials are BT. the bacteria as well as its toxin have long been used in organic farming as it is only activated in a highly basic (as in not acidic) envirument which is rather rare in nature execpt for the digestive system of several butterflies one of which is a major pest in cotton crops (i think its called pink worm something but its been a while). anyway the use of such plants mean many chemical treatments will be made redundunt which is good for the consumer as well as the envirument and the farmer. it has also been proven that although there is the ability to develop resistence to the toxin (in the lab) the living cost of of this resistence prevents its build up in nature. that along with the law that stats one has to grow at least 20% of the area with non BT plants aliminates the risk of its efectivness being damaged over time as happens to so many pesticides

BT(Bacillus thuringiensis) is a naturally occurring bacterium that is lethal to most leaf-eating caterpillars on trees, shrubs, flowers, and vegetables. Baci…llus thuringiensis variety kurstaki (B.t.k.) is the general purpose material that homeowners buy when they see just the words Bt or Bacillus thuringiensis without the variety name attached. This is the type of Bt that is appropriate for home landscape use to kill caterpillars. As you can see on the left, there are also varieties designed to kill mosquitoes or potato beetles. Bt is harmless to all other insects, animals, and humans. It comes in powder form for use as a dust or, diluted with water, for use as a foliar spray. It is also available in liquid form. It is sprayed or dusted on leaves of plants that are under attack by caterpillars so that the pests will ingest the bacteria as they eat the leaves. The Bt causes paralysis of the caterpillar's digestive tract, causing it to stop feeding within two hours. Within a day or two, certainly no longer than 72 hours, the caterpillars die.
Bt stands for bacillus thuringiensis, a common soil bacterium toxic to lepidopteran insects. When "Bt" is placed before a plant name, such as in "Bt Brinjal" (the brinjal is k…nown in the US as eggplant), it means the plant has been genetically modified to produce a protein toxic to certain insects in the same way the bacteria does. The protein has not been shown to be harmful to humans but is controversial in other contexts.
bt stands for British Telecom. They provide great value broadband, telephone, line rental and TV. They have a website that you can choose different packages to suit your wants… and most areas can have 4 months free.
Bt-corn is a type of genetically modified organism, termed GMO. A GMO is a plant or animal that has been genetically modified through the addition of a small amount of g…enetic material from other organisms through molecular techniques. Currently, the GMOs on the market today have been given genetic traits to provide protection from pests, tolerance to pesticides, or improve its quality. Examples of GMO field crops include Bt-potatoes, Bt-corn, Bt-sweet corn, Roundup Ready soybeans, Roundup Ready Corn, and Liberty Link corn.
1) High yield and resistance to bollworms
A gene isolated from a bacterium that produces a crystalline protein that when eaten by insects shreds their insides kills them. Acts as an effective biological alternative to… pesticide for this reason.
pesticide Bt cotton, or Bacillus thuringiensis cotton, is used the same as any other cotton. The only difference is that it has a protein genetically added which is identical… to that of B. thuringiensis bacteria which is toxic to many caterpillars, especially Lepidoptera species. Therefore it is an economically important "built-in" insecticide.
TRX stands for TRANSMIT RECEIVER. TRX has different combination depending on the user requirement. 1 trx has 8 TS out of which one is allocated for BCCH.Rest is used for voice… trxmns and for data purpose.
BTS stands for : Base Transceiver Station. It is situated near the user end at the mobile telecommunication towers.
Cotton is a soft, fluffy staple fibre that grows in a boll, or protective capsule, around the seed of cotton plants of the Genus Gossypium.
Cotton comes from cotton plants. In the US, the most common species is Gossypium hirsutum.
