I believe the answer is D) reactivity. Hope this helps. (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧
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).
Explanation:
a seasonal prevailing wind in the region of South and Southeast Asia, blowing from the southwest between May and September and bringing rain (the wet monsoon ), or from the northeast between October and April (the dry monsoon ).
the rainy season accompanying the wet monsoon.
Sexual reproduction offers genetic variation, as the offspring are a combination of 2 sets of genes opposed to one. This ultimately leads to evolution and the adaption to changing environments :)
