A. Transduction

Explanation:

Transduction is a type of horizontal or lateral gene transfer by which a foreign genetic information is transferred into a bacterial cell by a virus. The process of transduction doesn't necessarily require the physical contact between the DNA donating cell and DNA receiving cell. viruses and bacteriophages are used by molecular biologist to introduce a foreign genetic material into the genome of a host cell.

Adversely affected.

Explanation:

Dam adversely affected the organisms living in the estuary because dam controls the flow of water of estuary. Dams divide rivers that formed upstream and downstream habitats. The migratory fish depends on the natural environment and flow of river. Due to dams, change occur in rivers flow, the water temperature and natural conditions. This change prevents migratory fish from mating and/or hinders the development of fish larval.
