Explanation:
Better transportation infrastructure or transportation revolution in the early 19th century begins when people started crude roads instead or horses or river routes and then canals were built. After canals long the railroads crisscrossed the country that helped people and goods to move with greater efficiency. These technological developments in travel during the 19th Century connects the world and affects the national economy at high level.
Hence, the correct answer is "from roads to canals to railroads".
There would be no release of organic nitrogen molecules back to their inorganic state. Dead material would accumulate to choke out livable habitat.
<span>Plants fix atmospheric carbon in photosynthesis and some species of bacteria fix atmospheric nitrogen so life would continue taking these into the organic cycle but without decomposing fungi & bacteria the cycle would not complete. However the final step of reduction to N2 is only completed by bacteria. In fact bacteria are critical to every step of the nitrogen cycle. </span>
<span>Fungi also decompose dead plants and animals so are detrital feeders putting nitrogen into the nitrogen cycle but not as N2. Fungi cannot reduce N2O to N2. So fungi make N2O as their denitrification product. True denitrification, like nitrogen fixing, does not occur in eukaryotes only bacteria. </span>
The stage that involves the change and adaptation of a system is upkeep and maintenance.
Developing a new system is a complex process that requires multiple steps and stages. The most important stages are:
- Planning.
- Design.
- Development.
- Testing.
- Upkeep and maintenance.
From these stages, the last one "upkeep and maintenance" is the one that requires adapting the new system that has been already designed. This is the last stage because even after testing the system it is likely this has to be fixed or adapted, the most common reasons are:
- Fails that were not detected during testing.
- Upgrading the sytem.
- Including new features to meet customers' needs.
Based on this, the phase during which the system is fixed or adapted is the upkeep and maintenance stage.
