Answer:
In such type of research, where human nuclear material is used for the development of an embryo. So the same policies and concerns are applied as it is about the use of human embryonic stem cell.
Many scientists spent there many years on such research and their work has been standstill because of laws about stem cell research. Some laws ban the use of such an application.
Example: Dickey Amendment.
The statement that BEST describes the relationship between concentration and enzyme activity is when substrate concentration decreases, enzyme activity decreases (Option B).
- Enzymes are proteins that speed up chemical reactions by lowering the activation energy of that reaction.
- Some factors that alter enzymatic activity include temperature, pH, and substrate concentration.
- An enzyme works in optimum condition as long as there is more substrate available which can be broken down by the specific enzyme.
- However, the enzymatic activity increases as the substrate concentration until a limiting value is reached.
In conclusion, the statement that BEST describes the relationship between concentration and enzyme activity is when substrate concentration decreases, enzyme activity decreases (Option B is correct).
