Paleontologists are able to apply evidence from fossils to reconstruct the habitats of ancient extinct animals, such as dinosaurs. Which type of observation or measurement of the fossils provides the most useful evidence for this task?

A. DNA analysis, which reveal evolutionary relationships with modern animals
B. muscle tissue analysis, which reveal how muscles were used
C. measurements of radioactivity, which show the age of the fossil
D. observations of bone and joint structure, which show how an animal moved

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics

what bodys are there orbiting?

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project
