<span>If I were attempting to date a rock sample that I suspect to be incredibly old, i would use radioactive isotopes with a long half life. When dating rocks and fossils to discover approximately how old they are, radioisotope dating is used on igneous rocks found near fossils. Things like Uranium 235, which is an unstable radioactive isotope of elements, decays at a constant rate over time so can be useful in determining age.</span>

Answer:
underwater ecosystems formed in shallow water by the dense growth of several different species known as kelp's. ... Like those systems, though, kelp forests provide important three-dimensional, underwater habitat that is home to hundreds or thousands of species of invertebrates, fishes, and other algae.
Answer:
GAPDH inferring statement on evolutionary relationship
Explanation:
in order for GAPDH to useful for inferring evolutionary relationship among animals, their silico structural and phylogentic analysis must be true. By this it implies that GAPDH gene must be analyzed with respect to identity, similarity, physiochemical properties, secondary and tertiary structure through in silico platform.
