How does genetic variation and mutation play a role in natural selection?

2 answers:

7 0

Natural selection is a theory that states that those individuals who are best adapted to live in an area will survive and reproduce. Within a given population, there exists a normal degree of genetic variation that may or may not make an individual more adapted to the environment or, more importantly, changes in the environment. A species with a great deal of genetic variability is more likely to survive as a species in a changing environment than a species with limited variability.

Describe how oil and natural gas compare in terms of predicted supply and carbon dioxide emissions.

Shkiper50 [21]

Pounds of CO2 emitted per million Btu of energy for various fuels: gasoline 157.2, propane 139.0, natural gas 117.0. The amount of CO2 produced when a fuel is burned is a function of the carbon content of the fuel. The heat content or amount of energy produced when a fuel is burned is a function of primarily the carbon (C) and hydrogen (H) content of the fuel. Heat is produced when C and H
