Answer:
c)polymerase chain reaction (PCR).
Explanation:
Because the paleontologist recovered only a bit of tissue and it is very old, it is very likely that the DNA in the sample is very small and part of it is degraded. Anyway, the paleontologist must first amplify the DNA sample to obtain many identical copies of the specific region of the DNA they want to compare. the above is done through a polymerase chain reaction (PCR).
Assessing aggregate exposure to a series of compounds with the same biological mechanism is called cumulative exposure assessment.
<h3>
What is cumulative exposure?</h3>
Because cumulative exposure evaluations evaluate exposure to numerous stressors via different pathways, they are referred to as "combined exposure assessments." Exposures to a single stressor are estimated using aggregate evaluations from different sources and pathways.
Cumulative evaluations portray real-world exposure more accurately, but they also provide an element of complexity not seen in typical exposure assessments , which evaluate stressors separately.

Answer:
Están interconectados entre sí.
Explicación:
Existe una relación directa entre los intereses, las necesidades y las aspiraciones de la adolescencia porque todos están interconectados entre sí.
