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.
0.5. This is because if the cells have not swollen or shrunk then the water potential (and therefore amount of solute) inside and surrounding the cell must be equal.
The two processes that remove carbon dioxide from the atmosphere are photosynthesis and absorption. Respiration and volcanism, or the eruption of molten rock, are the two processes that provide carbon to the atmosphere.
carbon is removed from the atmosphere through photosynthesis and replaced with O2. O2 is removed from the atmosphere during respiration and replaced with carbon . These processes, however, are not in equilibrium. Not every organic substance oxidizes. Photosynthesis and metabolism are the two fundamental processes that take place during the natural carbon cycle. Plants consume carbon dioxide during photosynthesis to create oxygen, and they also make carbon dioxide during metabolism.

Hello again, I helped you with your geothermal question earlier.
I would believe that B would be correct, because if you decrease energy use, then you would use less energy when performing tasks.
At first the cells have the same number of chromosomes as mitosis. DNA replication occurs, giving a total of 46<span> chromosomes (or </span>23<span> chromosome pairs) and </span>92 chromatids<span> (or </span>46 chromatid<span> pairs).</span>
