Question

why are scientists concerned about the use of the bt toxin, which is used to kill insects, in genetic engineering? the bt toxin stays in the soil for long periods of time. the bt toxin has been known to cause disease in plants. the bt toxin is killing too many insects. the bt toxin gene is not readily accepted by plants.

Explanation:

The Bt toxin is a protein produced by the bacterium Bacillus thuringiensis. It is used in genetic engineering to create plants that are resistant to insect pests. However, scientists are concerned about the use of Bt toxin because it can stay in the soil for long periods of time. This can have negative impacts on soil health and the environment.

Answer:

The Bt toxin stays in the soil for long periods of time.
