Answer:
Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900)
Explanation:
this is happening due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
The layers of the sun, ranked from greatest to least distance from the sun's center, are: core, radiative zone, convective zone, photosphere, chromosphere, transition region, and corona.

The correct answer is H2 (hydrogen). H2 was not found in the atmosphere of the early Earth, while CO2, O2, and CH4 were.
When a bacterium picks up DNA from its environment, this is called transformation.
Oxygen (O2) was not found in the atmosphere of the early Earth. When a bacterium picks up DNA from its environment, this process is called transformation.
In the early Earth's atmosphere, gases such as carbon dioxide (CO2), methane (CH4), and hydrogen (H2) were present, but oxygen (O2) was not found in significant amounts. This is known as the reducing atmosphere. The absence of oxygen was due to the lack of photosynthetic organisms that produce oxygen as a byproduct.
When a bacterium picks up DNA from its environment, this process is called transformation. Transformation occurs when a bacterium takes up free DNA from its surroundings and incorporates it into its own genome. It allows for the transfer of genetic material between bacteria and can contribute to genetic diversity.
