Answer:
The correct answer is: Genetic modification
Explanation:
Genetic modification, also known as genetic engineering, refers to the use of biotechnology for the genetic manipulation of an organism.
This process involves altering the genetic makeup of an organism in order to produce improved and better organism. The organism produced with the use of this technique is known as the genetically modified organism.
Therefore, the given example of selecting the strains of original weed and then cultivating and fostering to produce genetically modified product is called Genetic modification.
Answer:
The correct answer is There is a specific pH range in which the enzyme effectively lowers the reaction"s activation energy.
Explanation:
There is a specific pH at which the an enzyme functions best is known as optimum pH.
Enzymes lowers the reaction"s activation energy but only at specific pH(optimum pH).If pH is increased or decreased the degree of ionization of various amino acids such as histidine,serine,glutamic acid present in the enzyme"s active site will be changed thus affecting the enzyme"s activity.
