Greenhouse gases arise naturally, and are part of the make-up of our atmosphere. Earths conditions are just right to allow life, including us, to flourish. Part of what makes Earth so amenable is the naturally-arising greenhouse effect, which keeps the planet at a friendly 15 °C (59 °F) on average. But in the last century or so, humans have been interfering with the energy balance of the planet, mainly through the burning of fossil fuels that give off additional carbon dioxide into the air. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and traps extra heat near the surface of the Earth, causing temperatures to rise.

Answer:Human height
Explanation:
Inheritance patterns are often more complex than predicted by simple mendalian genetics. When Mendel studied some phenotypic characters, like the human skin color and height, they were found to be an addictive effect of two or more genes on a single phenotypic character. These are called quantitative characters, which usually indicates polygenic inheritance.
The human height is an example of quantitative character, it is controlled by at least 3 genes having 6 alleles. 3 genes with 6 alleles from both parent can give rise to wide range of phenotypic character (heights).
