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.

What are the oldest cells in the world?
The oldest cells in the world are believed to be those of the bacterium Halobacterium salinarum found in salt crystals in a Chilean desert. These cells are estimated to be around 2-3 million years old.
Why do the crystals of Bt toxin produced by some bacteria do not kill the bacteria themselves?
toxin is inactive: In bacteria, the toxin is present in an inactive form, called prototoxin, which gets converted into active form when it enters the body of an insect
What does raphide crystal do in a plant cell?
Raphides are needle-shaped crystals, usually of calcium oxalate, found in more than 200 families of plants. The crystals discourage animals from eating the plant because they irritating the animalsâ?? tissue.
If my dog's pH is 6.0 does she have struvite crystals?
Struvite crystals are found in the urine when it's alkaline, usually when the Ph exceeds 7.0. Those crystals get deposited in the urinary tract to form stones. They are seen in infections with urease producing bacteria such as Proteus and Klebsiella. To diagnose struvite stones you need to do a urinalysis and culture of the urine to isolate the offending bacteria. An IVP (intra-venous pyelogram) will confirm the diagnosis and locate the stones.
Is amorphous urate normal in urine?
Amorphous urates are normal in urine. There are several types of amorphous crystals, each composed of different elements and forming in specific urine conditions. Amorphous crystals are misidentified as bacteria.
What are Magnetotactic bacteria?
-Use magnetite to orient to N/S poles -Have been around for a few Ga -Magnetite-like crystals found in ALH84001
Is it dangerous to swallow glass that's as small as sugur?
Swallowing any type of glass can be dangerous. Glass has small crystals in it and can tear up the digestive tract of a persons body.
What makes ice cream smooth?
Bacteria. but i do not remember which kind of bacteria.
Why should you never use ice in an unknown sroce of water?
The contaminants are concentrated in the void spaces in the ice crystals. Bacteria, floaties, everything. They are really not much safer than the water they are made from. (Some bacteria are killed by freezing, but probably not enough.)
What is sample ALH84001?
•Evidence for life -Presence of small organic compounds called PAHs -Small bacteria-shaped morphologies -Magnetite crystals Mars rock in question
