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.

What is the major cause of the greenhouse effect? view available hint(s) what is the major cause of the greenhouse effect? exces
Strike441 [17]
The major causes of the greenhouse effect is excessive carbon dioxide gas in the atmosphere. The greenhouse effect is a process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by green house gases, such as carbon dioxide, water vapor, metahne, nitrous oxide, and ozone. The absorbed energy warms the atmosphere and the surface of the Earth.

Based on the phylogenetic tree below, which groups of plants evolved most recently?
xeze [42]

Answer: The correct answer is- gymnosperms and angiosperms.

Phylogenetic tree is a diagrammatic representation that depicts the evolutionary relationship among different group of species. In other words, it is used to interpret the relatedness among different species and how they have descended from a common ancestor.

The tips in the phylogenetic tree represents the taxon ( or particular group of species) that are descended.

In the given tree, gymnosperms and angiosperms have evolved most recently because they correspond to the most recent branches having the immediate common ancestor at the topmost level as compared to the immediate common ancestor of other taxon.

Thus, gymnosperms and angiosperms is the right answer.

Approximately what percentage of the human genome actually codes for proteins?
34kurt

The correct answer is: 2.5%

The vast majority of the human genome (97.5%) is comprised of non-coding DNA with different functions. Non-coding DNA includes telomeres, introns, non-coding RNA genes and gene regulatory sequences.

• Telomeres-ends of DNA with protective role (prevents shortening of DNA),

• Non-coding RNA genes-e.g. genes for tRNA,

• Gene regulatory sequences such as promoter, enhancers and silencers.
