Are you looking for their name?
They are called chemotrophs; this means that they obtain their energy from chemical reactions.
They are different from phototrops, which obtain their energy from the sun, mostly through the process called photosynthesis.
Let me know if you were looking for something else than a name and if there were options:)
Answer:
In my opinion, if the United States were not a set of unified states under a single national government but rather a set of independent nations without ties to each other, the quality of life of the inhabitants of each independent state would drop considerably. This is so because the economies of each state would be significantly less decisive than the American economy in general, and except for specific cases such as California, Texas or New York, the rest of the states would have a notable lack of resources that should be compensated through unfavorable trade treaties with other countries. In addition, the demographic and political weight of each state would be much smaller, which would not be able to obtain the same commercial benefits that are obtained today, which would generate a greater lack of jobs and a decrease in the quality of life of the citizens.
The explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the Redshift- Doppler effect.
<h3>What is the Doppler effect?</h3>
The Doppler effect is the difference that occur between the frequency of a wave in relation to observer from the wave source.
The wavelength changes with change in the frequency.
<h3>How does the Doppler effect explain the redshift?</h3>
As an object moves away from Earth, the waves moves to the red end of the electromagnetic spectrum and becomes elongated. This results to the increase in wavelength.
Therefore, the explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the redshift-Doppler effect.
