Bt corn is a genetically modified crop that contains a gene from another species. Which characteristic does this gene give the plant

A. Sweeter flavor

B. Drought tolerance

C. Taller stems

D. Insect resistance

The right answer is D.

The effectiveness of BT-Corn compared to conventional insecticide treatment is very much higher:

* The plant itself produces the toxin that blocks the digestion of or target insects: the entire plant is protected where a treatment (out of neonicotinoids, very expensive and reserved to the seed treatment) allows only a protection of surface and must be renewed several times.

* The selectivity of the treatment is very superior: each variant of the BT molecule targets only a family of insects but we do not know the impact of their cumulative effects in the environment.
