A paleotndologist finds a bone that might be a sauropod’s bone. In the laboratory, she finds that the Carbon-14 found in the bone is 1/10 of that found in a living bone tissue. Could this bone have belonged to a sauropod? Explain your reasoning. (Hint: The sauropods lived from 200 million years ago to 145 million years ago. The constant for Carbon-14 is 0.00012.)a.) No, because the amount of Carbon-14 found indicates a period before the sauropods even came into existence.b.) No, because the amount of Carbon-14 found indicates a period after the sauropods became extinct.c.) Yes, because the number of years calculated is in the range of 200 million years and 145 million years ago.d.) Yes, because the amount of Carbon-14 found in the bone is one-tenth of that found in a living bone tissue.

The top running speed of a cheetah is double the top running speed of a jackal. The top running speed of an elk is 11 miles per hour faster than that ofa jackal. If each of these three animals could run at top speed for an hour (which, of course, is not possible), they could run a combined distance of 151miles. What is the top running speed of each of these three animals?
