The rapid speciation of mammals as a result of the availability of new habitat due to the extinction of the dinosaurs 65 million years ago is an example of adaptive radiation.
Answer:
Before answer this question, you need to know what is the half-life of a compound, the term half-life is defined as the time it takes for one-half of the atoms of a radioactive material to disintegrate. Knowing this you know that has passed half of the half-time, so you should probably have 25% of the original amount of 235U. This problem may be tricky because it says half of the time to reach the half-time, but 50% of the compound will be present in 750 million years after the death of the specimen.
Processes that are most important to human life are oxygen, required for cellular respiration, and glucose, a form of sugar that releases energy during cellular respiration.
