Answer:
How are the water carbon and nitrogen cycles related?
The three main cycles of an ecosystem are the water cycle, the carbon cycle and the nitrogen cycle. These three cycles working in balance are responsible for carrying away waste materials and replenishing the ecosystem with the nutrients necessary to sustain life.
Explanation:
I believe the correct response is A. Can be separated by physical means.
Answer:
True
Explanation:
Carbon dioxide is transported by the blood in the dissolved form. carbonic anhydrase is the enzyme which is a metalloenzyme having zinc at active site converts carbon dioxide into carbonic acid which dissolves in the blood.
Thus,
H₂O (l) + CO₂ (g) ⇔ H⁺(aq) + HCO₃²⁻(aq)
The kidneys in the body help to control the acid base balance. The hydrogen ion secretion in the body leads to the generation and reabsorption of the bicarbonate ions to form carbon dioxide in order to nullify the effect of the acid generated and thus the pH of the blood is maintained.
Answer:
Theory
Explanation:
Science is empirical in nature. It massively depends on the gathering of a large body of evidence to support one's idea.
In the scientific method, observations are subjected to rigorous experimentation until a large data of empirical evidences support such idea.
When such idea has been supported by massive empirical evidence, we now call it a theory.
