Answer:
Metabolic Engineering
Explanation:
Metabolic engineering refers to the process of modifying the genetic and enzymatic processes within cells in order to optimize the output of products. When constraints are noticed in the normal biological process, scientists endeavor to modify the constraints so that wide scale production can be realized.
Examples of processes that incorporate this technique are beer, cheese, wine and some drugs production.
Anaerobic respiration was very weak because the earth had no harmful chemicals in the air at the time
Answer:
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere
