Biotechnology is best defined as what?
Lubov Fominskaja [6]
My answer -

<span> Biology is the study of living organisms. Biotechnology involves creating solutions to problems using living organisms. It's more like how mechanical engineering uses machines to solve problems or how computer engineering uses computers to solve problems.

The problems that biotechnology works to solve can range from medical treatments (like stem cells) to advancements in agriculture (disease or drought resistant plants, food with higher nutritional value) to industrial processes (bacteria developed to replace toxic compounds used to make paper, bacteria and algae that produce biofuels).

P.S

Happy to help have an AWESOME!!!! day :)
