Which statement is correct?

A. Modern biotechnology is the use of natural organisms by humans to create or modify foods or other useful products. Examples of modern biotechnology include using yeasts for fermentation and practicing selective seed collection to create hardier crops.

B.  Traditional biotechnology is the use of natural organisms by humans to create or modify foods or other useful products. Examples of traditional biotechnology include using yeasts for fermentation and practicing selective seed collection to create hardier crops.

He was a French chemist who made several key discoveries. He proved that infectious diseases were caused by microorganisms,

This process of traditional biotechnology began over 10,000 years ago when our ancestors started keeping plants as a reliable source of food. Rice, barley, and wheat were among the first tamed plants. Wild animals were tamed to provide milk or meat or help with plowing or guarding the farm.

What do you call the process of chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of the heat?

We are being used in recombinant DNA work because we are eukaryotes and hence have the same sort of genetic structure as humans, secrete proteins in a similar way, and so on, but are almost as easy to ferment as bacteria.
