Statement 3 is correct; genetic engineering can be employed to develop microorganisms with improved pollutant degradation efficiency or resistance to toxic environments, specifically designed for bioremediation applications (e.g., genetically engineered bacteria). Statement 2 is incorrect. While bioremediation is effective for many organic contaminants, heavy metals like cadmium and lead are elemental and cannot be degraded by microorganisms. Bioremediation techniques might be used to immobilize or transform them into less mobile forms (e.g., through biosorption or bioprecipitation), but they are not &#8216;readily and completely treated&#8217; by degradation.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>In the context of solving pollution problems, what is\/are the advantage\/advantages of bioremediation technique? 1.
