Unless this is the natural ploidy for the organism – like in some plants – then the resulting zygote would not develop or the resulting mature organism would have abnormalities.
Answer:
Cola: Nonrenewable
Geothermal Energy: Renewable
Wind: Renewable
Gas: Nonrenewable
Explanation:
Coal: Is classified as a nonrenewable energy source because it takes millions of years to form
Geothermal Energy: Its a source that has almost an unlimited amount of heat generated by the Earth's core.
Wind: Is a source of energy which is non-polluting and renewable using wind to produce energy has fewer effects on the environment than many other energy sources
Natural Gas: Formed from the remains of tiny sea plants and animals that died 300-400 million years ago
