Is by producing money for everyone
The answer to the question is B
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.
To answer this question you must break apart the words given on the right.
“Eco” means life and production. So an ecologist would be someone who studies life and it’s processes. So the correct answer for the first blank would be C. Life Science.
A chemist is one who interacts with day to day elements and sciences that is tactile. So the most appropriate answer would be B. Physical science.
A geologist is someone who studies the earth. As the part of the word “geo,” meaning earth, suggests. So the correct answer here would be A. Earth science.
Finally, “Astro” means space .Astrology is the study of the stars and the sky, for example. So, D. Space science would be the best answer for an astronaut.
I hope all of these are helpful. :)
