This is an example of natural selection. The finches with the most ideal beaks survive because the environment they live in allows them to gather resources more easily than other species.
Well a hypothesis is guess about an experiment and how it works or is preformed. If your supporting one then you agree with how its done and how it works and you got good results. If you fail a hypothesis that means you most likely tried and didn't succeed or didn't get the results you wanted. Sorry if this is confusing the question kinda confused me.
c The fall line is where rivers are no longer navigable by ships traveling in from the ocean, so goods had to be offloaded.
Explanation:
Cities tended to develop at the fall line of rivers simply because rivers are no longer navigable by ships travelling from the ocean and goods have to be offloaded.
- The fall line provides a natural demarcation where a coastal plain meets the upland area.
- From this area, a river enters into the ocean.
- Ships are built to navigate the ocean. Their design makes it impossible for them to coast through rivers which are smaller water bodies.
- This prompts ships coming to offload around the region where the coastal plain meets the upland area the river is coming from.
- Harbors and docks are usually built in such areas.
- They are hubs of trade and commerce attracting a large population of people.
- Therefore, cities invariably emerge.
