If a fossil is encased in a stratum of sedimentary rock without any strata of volcanic rock (for example, lava or ash) nearby, t
hen it should be ________. (A) easy to determine the absolute age of the fossil, because the radioisotopes in the sediments will not have been "reset" by the heat of the igneous rocks
(B) easy to determine the absolute age of the fossil, because the igneous rocks will not have physically obstructed the deposition of sediment of a single age next to the fossil
(C) difficult to determine the absolute age of the fossil, because the "marker fossils" common to igneous rock will be absent
(D) difficult to determine the absolute age of the fossil, because radiometric dating of sedimentary rock is less accurate than that of igneous rock
If a fossil is encased in a stratum of sedimentary rock without any strata of volcanic rock (for example, lava or ash) nearby, then it should be
(D) difficult to determine the absolute age of the fossil, because radiometric dating of sedimentary rock is less accurate than that of igneous rock
Because sedimentary rock radiometric dating is less precise than that of igneous rock, it should be challenging to estimate the absolute age of a fossil if there are no nearby volcanic rock layers (for example, lava or ash) to compare it to.

If a major change in pH occurred, the protease enzymes would stop functioning or function very slowly, assuming the original pH was the most optimal pH for them.
