Answer:
E.coli is a bacterium which is preffered for transformation due to its rapid growth and high efficiency of introduction of DNA molecules into cells.
Tetracycline is an antibiotic used to treat several infections such as cholera, plague, brucellosis, and malaria etcetra.
Plasmid is a small, extrachromosomal DNA molecule present in cell which is seprated from chromosomal DNA and have ability to replicate independently.
When a plasmid resistant to tetracycline and kanamycine is inserted into E.coli, the process is called transformation. E.coli might not be able to survive due to absence of plasmid but the transformed strains having antibiotic tetracycline and kanamycine will probably be able to survive it. 
Hence, the culture of bacteria carrying plasmid will be able to survive only.

The reaction shown in the question is an inversion reaction.
The conversion of maltose to glucose is an inversion reaction. An inversion reaction is said to have occurred when the atoms and groups in a molecule are rearranged. The numbers and type of each atom in a molecule remains the same.
The reaction; Maltose +A -> Glucose + B is an example of an inversion reaction. The missing items A and B are both the catalyst maltase.
