Study Notes
Renewable Energy and Sustainability
- Solar energy is mentioned as a generally more sustainable option than fossil fuel sources.
- Sustainable energy is described as energy that is replenished at the same rate it is used, and is a key component of a sustainable future.
Nuclear Power and Sustainability
- A controversial aspect of nuclear power's sustainability is the disposal of radioactive waste.
Carbon Emissions Reduction
- Carbon capture technology can be built into power plants to remove their carbon dioxide emissions.
Environmental Benefits of Natural Gas
- Switching from coal to natural gas provides the environmental benefit of reducing greenhouse gas emissions.
Genetics and Inheritance
- Heredity is the term for the passing on of traits from parents to their offspring.
- The example of blue eyes best represents an inherited trait.
- The complete set of genes within an organism's genome is called the genome.
- DNA (Deoxyribonucleic acid) is the molecule that encodes genetic information and is known to pass heritable traits from one generation to the next.
- The struggle for existence and the resulting variation in reproductive success cause species to evolve by natural selection.
