- Speciation
- Regeneration
- Homeostasis
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Definition.
- Homeostasis is the maintenance of a stable internal environment in an organism despite changes in the external environment.
Step 2: Importance.
- Ensures optimal conditions for enzyme activity and metabolic processes.
- Regulates temperature, pH, osmotic balance, and blood glucose.
Step 3: Mechanisms.
- Negative feedback loops maintain stability.
- Example: Insulin and glucagon regulate blood sugar.
Step 4: Comparison with other options.
- Mutation: change in genetic material.
- Speciation: formation of new species.
- Regeneration: replacement of lost or damaged parts.
Step 5: Conclusion.
Hence, the dynamic constancy of the internal environment is called Homeostasis.
- Homeostasis is the maintenance of a stable internal environment in an organism despite changes in the external environment.
