Answer:
I’m pretty sure it’s all of the above!
Explanation:
Answer:
Because it is only possible to be 100% sure that two species are closely related, in genetic terms, when the DNAs of these species can be analyzed. This analysis is only possible through molecular tests.
Explanation:
Molecular tests are bikini techniques that can analyze species at the molecular level, more specifically, these tests can deeply analyze the DNA (or RNA and proteins) of a species giving precise results on the molecule and allowing scientists to study it deep.
In studies, where the scientist wants to know how the species are genetically related, it is common for molecular tests to be introduced, as a way for the scientist to be 100% sure of the relationship between the species.
Answer:
Explanation:
Nucleic acids are the organic materials present in all organisms in the form of DNA or RNA. These nucleic acids are formed by the combination of nitrogenous bases, sugar molecules and the phosphate groups that are linked by different bonds in a series of sequences. The DNA structure defines the basic genetic makeup of our body.
<span><u>How does fossilized carbon get back into the atmosphere?</u>
</span>Fossilized carbon is coal. One major way it gets back into the atmosphere is by humans burning it in coal power plants. Carbon gets back into the atmosphere as carbon dioxide through the combustion of fossil fuels.
<span><span><u>How does a plant get nitrogen from the soil?</u>
