Explain all answers clearly, with complete sentences and proper essay structure if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.
Rise of the Mammals. Suppose the impact 65 million years ago had not occurred. How do you think our planet would be different? For example, do you think that mammals still would eventually have come to dominate Earth? Would we be here? Defend your opinions.

- PROBLEM SOLVING: Express your answer to the fourth decimal places. Show complete solution. Box your final answer. 1. A wooden object found in an Indian burial ground and subjected to radiocarbon dating. The decay rate associated with C-14 is 10 disintegrations per minute per gram carbon. What is the gge of the obiect?arrow_forwardIn determining the least count of the main scale in the Vernier caliper, which of the following method must be followed? * O Divide the difference between two adjacent main scale values by the number of divisions between them. O Divide the least count of the main scale by the number of division of the Vernier scale. Multiply the least count of the Vernier scale by the number of Vernier division that is aligned with the main scale mark. O Read the main scale mark just before the zero mark of the Vernier scale.arrow_forwardPlease include a complete answer. Do not skip any steps.
