C) and D).only #11 plate is a negative control since he utilized the spinach which isn't cleaned. so microorganisms can develop on that pate because they have the positive condition to develop themselves.  

e) and f). all #1 - #10 and #12 plates are positive control plates since he swipes all the plates and spinach that can be the reason for the development of microbes so there is an excess of fewer opportunities to the defiling of spinach and he is playing it safe.

. Imagine the following scenario. A bacteriophage taken for the treatment of cholera infects a cholera-causing bacterium and tem
SSSSS [86.1K]

Answer:

The virus will transfer the DNA encoding cholera toxin to the next bacteria it infects, which will make that bacteria cholera-causing.

Explanation:

The process described in this question is a kind of gene transfer in bacteria called TRANSDUCTION. Transduction is the transfer of fragments of DNA from one bacterium to another via a virus called bacteriophage.

As stated in this question, the virus (bacteriophage) infects a cholera-causing bacterium. The bacteriophage moves from lysogenic cycle to lytic cycle and includes some pieces of the bacterial DNA, which encodes information for making the cholera toxin, in its own genome.

This means that the cholera-making toxin DNA is now a part of the virus's genome and hence, will transfer it to the next bacteria it infects in a process called TRANSDUCTION. This will make that bacteria a cholera causing bacteria.
