Answer:
solid, liquid, and gaseous water
Explanation:
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.
