The answer to this question is true
Answer:
The weeds will become tolerant to the herbicide through repeated exposure.
Explanation:
Genetic engineering refers to the procedures that are used to change the genetic composition of an organism by supplementing the desired genes. The herbicide-resistant crops are developed in order to withstand specific broad-spectrum herbicides that destroy the surrounding weeds, however, leave the cultivated crop intact.
The cultivation of herbicide-resistant crops encourages and substantially enhances the application of herbicides, leading to overuse of herbicides, in order to maintain the production of crops. However, this overuse application of the herbicides will eventually result in the generation of weeds that become resistant to herbicides.
