DNA are segments of genes that form tight coils called chromosomes
A)Storage
b)Glucose molecules
Glycogen is a storage of carbohydrates and is made of many glucose molecules.
Answer: The correct answer is-
C. Insulin secretion in response to high blood sugar.
D. Increased heart rate in response to exercise.
F. Proton pumping to maintain a proper pH level.
Homeostasis can be described as a tendency of living organisms to maintain a state of stable internal environment. In other words, it is the tendency to resist any change in the optimal conditions for survival.
It is brought by several regulatory mechanisms in the body such as regulation of body temperature, regulation of pH, regulation of osmolarity etc.
- Whenever there is high blood sugar level, insulin hormone is secreted from pancreas that reduces the blood sugar level.
- Heart rate is increased in response to exercise so that more oxygen is transported through blood circulation and more amount of energy is harvested through cellular respiration in the form of ATP ( required in exercise).
- Pumping of proton maintains a proper pH level ( such as in lysosomes, where pH is highly acidic, high proton concentration is regulated through proton pumping).
Thus, option C), D), and F) are the examples of feedback mechanisms that help in maintaining homeostasis.
