Sam needs to use some technology as a safety measure to prevent the genetically modified crops from spreading beyond the area they are planted in. He can use the technology to make the seeds of genetically modified plants sterile.

Genetic use restriction technology.

Explanation:

Genetic use restriction technology is the technology used by the Sam in order to make the seeds of genetically modified plants sterile in order to prevent the plant from spreading. This technology is used for restricting the use of genetically modified plants by activating or deactivating several genes which cause second generation seeds to be sterile which means these seeds will not grow again.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
