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.

Between usage with various meals, food service personnel should clean and sterilize surfaces, tools, and utensils, especially after handling raw meat. Foods that are ready to consume should be kept in the refrigerator's highest shelves. This will prevent the juice from raw foods from dripping down and contaminating the prepared food.
<h3>How may pathogens be kept out of food?</h3>
- Wash hands and other surfaces often.
- Before and after handling food, going to the bathroom, changing diapers, or touching pets, wash your hands with soap and hot water.
- To clean up spills or kitchen surfaces, use paper towels or clean cloths along with hot, soapy water.
<h3>How do food workers guard against viruses on their hands contaminating food?</h3>
The gloves that food workers wear could be infected with harmful infections if they don't properly put them on or don't wash their hands before putting them on. Every time an employee dons a fresh set of gloves, they must wash their hands first.
<h3>How can employees prevent food from becoming contaminated after it has been cooked?</h3>
To make sure food is safe to eat, use a food thermometer, keep food hot after cooking (140°F), and microwave food thoroughly (165°F). Refrigerate right away because if perishable goods aren't chilled, bacteria that cause disease can grow in them in just two hours.
