All life has a common ancestor which can be traced through different lineages. Due to the fact that any new generation comes from two parents who do not share the same features. As the number of generations increases the resemblance to previous ancestors begins to minimize. For example I have brown eyes just like my mother, however, my great great grandmother had hazel eyes.
Renewable resources are so abundant or are replaced so rapidly that, for all practical purposes, they can't run out. ... Renewable resources include solar, wind, hydro, and (possibly) biomass.
Answer:
Potassium-40
Explanation:
Potassium-Argon dating is the most efficient radioactive dating method in order to determine the absolute age of the fossils. It involves the decay of unstable Potassium-40 (K-40) into a stable Argon-40. The half-life of this Potassium-40 is approximately 1.3 billion years, so it is very much helpful to date the rocks that are of about 4.6 billion years to 100,000 years old.
Thus, the K-40 radioactive isotope would be the best to determine the exact age of the fossil that is found in the rocks that are about 600 million years old.
Plant hormones are chemical plants use for communication, coordination, and development between their many cells.
