About 9,000 years ago people generated a new plant species, Zea mays (maize/corn), through the domestication of a grass known as teosinte. In comparison to teosinte, modern ears of corn are much larger, have many more rows of corn grains, have softer corn grains, and do not shatter (break apart to scatter the grains). Which of the following most accurately describes the generation of corn? Multiple Choice Corn was generated through natural selection because natural selection is the only mechanism of evolutionary change. Corn was generated through natural selection because the teosinte grass naturally evolved into corn. Corn was generated through artificial selection because people selected traits in teosinte that they deemed desirable. Corn was generated through artificial selection because there was a horizontal transfer of genes from one species to another. Corn was generated through natural selection because artificial selection requires gene-editing technologies.

Industrial Processes

Industrial processes result in the manufacturing of products (biological products, such as enzymes, medicine) on a large scale using different methods, such as physical and chemical procedures. Few products such as pharmaceuticals, agricultural products, food items, etc., involve microbes and their enzymes. Such processes are termed industrial biological processes. Microbiology and biotechnology enable us to utilize the ability of microorganisms to produce enzymes, primary metabolites, and secondary metabolites, which in turn help to produce the desired products.
