What does bacillus thuringiensis do?
Bacillus thuringiensis (Bt) is a type of bacteria that produces toxins deadly to certain insects, particularly caterpillars and larvae of moths and butterflies. It is commonly used as a natural insecticide in agriculture to control pest populations without harming beneficial insects or other organisms. When ingested by susceptible insects, Bt toxins create pores in their gut walls, causing them to die from starvation or infection.
What is the appearance of a 24-hour Bacillus culture?
A 24-hour Bacillus culture typically appears as opaque, slightly raised colonies with irregular edges on agar plates. The colonies are generally cream-colored, smooth, and may have a matte or slightly shiny surface. Bacillus species are known for their distinctive appearance and can exhibit variations in color and texture depending on the specific species.
What is Bacillus Lactis used for?
The benefits of Lactic Acid Bacillus and other probiotics documented for humans have also been documented for aqua and vet. The indications for humans includeDiarrhea of various causes.Infantile, weaning, and neonatal diarrheaTo prevent antibiotic induced G.I. DisordersAntibiotic associated diarrheaPseudo membranous colitisConstipationAnorexiaAphthous stomatitis, glossitisAlong with ORTLactose intoleranceFor better absorption of micro-nutrients during diseases.
How many generations of humans have existed throughout history?
Throughout history, there have been approximately 100 billion generations of humans.
What best expresses the degree of success that has been attained in the cloning of humans?
Cloning of humans has not been achieved successfully. Ethical concerns and technical challenges have so far made it illegal and difficult to accomplish.
What does ''bt'' stands in bt brinjal or bt cotton?
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 known 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.

How can the bacteria bacillus thuringiensis be used to control insects in crops since they produce protein crystals that are toxic to the digestive system of insects?
the bacteria bacillus thuringiensis produce protein crystals that are toxic to yhe digestive system of insects.How can these bacteria be used to control insects in crops?Apply the bacteria to growing plants. Bio technologists have devised a method to utilize Bacillus thuringens to prevent insects on crops. They insert the gene responsible for the protein crystals into the genome of the crop plants and culture the plants. The resultant plants produce the protein crystals by themselves because they contain the gene to do so. An example of the above method is Bt cotton. It is a high grade cotton plant which is naturally resistant to pests as it has been genetically engineered.
Where can bacillus anthracis be found?
Bacillus anthracis, the bacterium that causes anthrax, can be found in soil and animal products contaminated with spores. It is commonly found in regions where livestock have been infected with anthrax. It is important to note that anthrax is not typically found in humans or in urban environments.
Catepillars are killing your plants - how can you get rid of them?
Bacillus thuringiensis or BT is a type of bacteria that's used to control the population of caterpillars. This natural pest control has been used by farmers and gardeners since the 1930s. Commercial preparations of the bacteria are still widely available today in feed stores and garden shops around the country. An alternative would be deltamethrin or permethrin dust.
From where the bacillus cereus take energy?
I Don't know! Been looking for days......
What is an example of a transgenic tobacco?
Example of a transgenic tobacco plant is the insect resistant variety. A gene from Bacillus thuringiensis which is lethal to many pests is introduced into the plant genome to impart resistance to many insect pests.
What is the use of bt cotton?
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.
How was an elephant used by humans in ancient times?
Elephtants have been co-existing with humans for thousands of years. Ancient kings of India had huge elephant armies at their command. Even after kings were no more, humans have been using elephants for helping in logging, moving large items etc. and for ages people have been hunting them for sport and for their tusks.
What are some GMO examples?
[1] Corn to which the naturally occurring bacterium Bacillus thuringiensis has been transferred. Bt corn thereby has crystal proteins that are lethal to corn borers and corn earworms. [2] Potatoes genetically modified for higher starch contents. [3] Potatoes and tomatoes to which the antifreeze genes of cold water fish have been transferred. Seedlings thereby have better responses, and show better survival rates, to cold temperatures. [3] Rice that has been genetically modified, to contain beta-carotene and more iron. [4] Soybeans that have been genetically modified so as not to be affected by Roundup. The weedkiller thereby needs to be applied once, not several times.
Have humans been to Mercury?
no. no humans have ever been to any of the other planets.
