Why might genetically engineering a crop to be herbicide resistant result in producing weeds that are herbicide resistant?
a. the genetically engineered design is flawed so weeds are not affected.
b. the weeds that are not affected by the herbicide are able to reproduce.
c. insects that are not affected by the herbicide can pollinate new species of weeds.
d. the weeds will become tolerant to the herbicide through repeated exposure.

Answer;

B. The weeds that are not affected by the herbicide are able to reproduce.

Explanation;

Genetic engineering (GE) refers to techniques used to manipulate the genetic composition of an organism by adding specific genes.

Herbicide resistant crops are designed to tolerate specific broad-spectrum herbicides, which kill the surrounding flora, but leave the cultivated crop intact.

Cultivating herbicide resistant crops promotes, and significantly increases, herbicide use, forcing farmers onto a chemical treadmill; with ever increasing quantities of herbicides necessary to maintain their crops.

colors do exist. the color of the sky is actually violet; humans percieve the color of the sky as blue.
