The correct answer is: Genetic modification

Explanation:

Genetic modification, also known as genetic engineering, refers to the use of biotechnology for the genetic manipulation of an organism.

This process involves altering the genetic makeup of an organism in order to produce improved and better organism. The organism produced with the use of this technique is known as the genetically modified organism.

Therefore, the given example of selecting the strains of original weed and then cultivating and fostering to produce genetically modified product is called Genetic modification.

me i can you if you would like.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
