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).
The answer is D) carbon forms both single and double bonds.
Answer:
The sample mean is obviously different from the population mean, but tests of significance must be done to determine if the difference is statistically significant. The difference could possibly be attributed to chance or to sampling error.
