where are equations dear????
The solubility of a gas (Sgas) is directly proportional to its partial pressure (Pgas). what pressure of carbon-dioxide is required to keep the carbon dioxide concentration in a bottle of club soda at 0.12 M at 25 degrees Celsius ? 0.12 M = 3.4 x 10^-2 (Pgas?)
Answer:
through natural selection
Explanation:
Natural selection is the driving mechanism of the evolution of species. Organisms can survive more in an environment if they are capable to adapt the changing environmental conditions. After surviving they are also able to pass their modified trait into their future generations (evolution).
