Living environemnt answers Scientists have incorporated a barley gene into a type of rice and produced rice plants that have muchlower methane emissions. It is most likely that the scientists incorporated the barley gene into therice, producing a new variety, using the process of:.

genetic engineering

Explanation:

Genetic modification or Genetic engineering is the method of using recombinant DNA (rDNA) technology to change an organism's genetic makeup.

In Genetic egineering a gene is isolated from the body of one organism and incorporated into the body of host cell in order to produce new gene variety with some advantages.

Here also, scientists have incorparetd a barley gene into a type of rice that developed a new rice variety with muchlower methane emissions.

Hence, the process used by scientists is genetic engineering.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

do yall know the answer?
