Hello everyone here we have a question asking which of the following statements is false regarding the significance of bacterial conjugation. A. They can move genes in bacteria that confer antibiotic resistant or cause diseases. Bacteria can exchange special D. N. A. Fragments that contain genetic information during congregations. And these can include genes that assist them in antibiotic resistance. So A. Is incorrect. Be bacteria can increase their genetic diversity through conjugation. A bacterium can donate a plasma containing genes for proteins that are responsible for antibiotic resistance through bacterial conjugation which increases the genetic diversity. So B. Is not our answer because we're looking for the false statement. See resistance to hazardous environmental conditions could be transferred when two bacteria attach and combine their genetic material. This process increases genetic diversity. So a novel gene combination is produced which means that the bacteria have conjugated that are more resilient and challenging environments. So this statement is true. So it is not our answer. D Both bacteria benefit through exchanging genetic material to survive the harsh environment during conjugation. One bacterium is the donor of the genetic material and the other is the recipient. The donor is not benefiting through X. Exchange of genetic material but the recipient is so D. Is incorrect. Which means that is our answer. Thank you for watching. Bye.
