Answer:
The Atmosphere
Explanation:
1816 was a year without summer because the billions of tons of ash that was spewed blocked radiation preventing it from reaching the surface of the earth.
A volcano is a break in the crust of planetary bodies like Earth that allows gasses, volcanic ash, and hot lava to escape. Volcanos are one of the major factors that cause climate changes on Earth mostly because of their cooling effect.
The ash, gasses and lava usually escape to the atmospheric layer of the earth with their cooling effect. And they cool the earth by blocking incoming solar radiation. This can go on for months or years depending on the components and severity of the eruption and can lead to "a year without summer" as witnessed in 1816.

Answer:
Polygenetic inheritance
Explanation
Polygenetic inheritance also called Multifactorial inheritance it occurs when a single characteristic is controlled by more than two genes .
An example is the human skin pigmentation which is determined by the amount of melanin it contains.
Melanin production involves at least four genes. A combination of of melanin producing allele determines the degree of pigmentation.
This shows each gene has exerted a small addictive effect in determining the trait.
Answer:
