Answer: The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.
Explanation:
1. Structure such as the human tailbone or appendix that evolution has reduced in size because it is no longer used = d. vestigial structure
2. study of the similarities and differences in the structures of different species:
= g. comparative anatomy
3. structure that is similar in related organisms because it was inherited from a common ancestor: = c. homologous structure
4. study of the similarities and differences in the embryos of different species: study of the similarities and differences in the embryos of different species = j. comparative embryology
5. scientist who finds and studies fossils to learn about evolution and understand the past:
= i. paleontologist
6. mistaken idea of jean baptiste lamarck that evolution occurs through the inheritance of traits that an organism develops in its own lifetime: = h. inheritance of acquired characteristics
7. process by which a single species evolves into many new species to fill available niches:
= e. adaptive radiation
8. relative ability of an organism to survive and produce fertile offspring: = k. fitness
9. structure that is similar in unrelated organisms because it evolved to do the same job, not because it was inherited from a common ancestor: = f. analogous structure
10. study of how and why plants and animals live where they do: = a. biogeography
11. process in which organisms evolve traits useful to humans because people select which individuals are allowed to reproduce and pass on their genes to successive generations:
= b. artificial selection
Answer:
population need to be willing to adapt to their environment
