Question

what is a reason farmers may choose to plant genetically modified crops? a higher tolerance to weeds b fewer tractors needed c saves time during harvests what is the transfer of genes or pieces of dna from one organism to another? a dna cloning b genetic engineering c cellular stemming what could be a negative impact of planting crops that have been engineered to make their own pesticides? a could harm beneficial insects b could be harder to replant c could grow without stopping

Explanation:

The transfer of genes or DNA between organisms is a core process in genetic engineering. DNA cloning focuses on复制 DNA, and "cellular stemming" is not a standard term. For engineered pesticide-producing crops, harming beneficial insects (e.g., pollinators) is a known negative impact; other options are less relevant.

Answer:

B. genetic engineering
A. could harm beneficial insects
