<u>A. Building dams, deforestation cutting down trees), adding point sources to nearby streams to allow for run-off, building roads and structures, and salting roads.</u>
Explanation:
Removing non-native species from the environment helps the native ants to thrive without having any changes in the ecosystem effect them (i.e. new invasive animal).
Creating laws to prohibit fishing from local streams helps keep the fish alive and allowing them to continue to use this stream.
Planting trees and other plants to attract native species helps secure and grow the ecosystem of that area.
<em>This leaves </em><em>A</em><em> </em><u><em>as the answer.</em></u>
Divergent evolution is the process of two or more related species becoming more and more dissimilar. In this type of evolution groups of species from the same common ancestor evolve and accumulate differences, resulting in the formation of new species.
For example; <em><u>The red fox and the kit fox. The red fox and the kit fox both have a common ancestor but have gone through the process of divergent evolution. It has adapted to its mixed farmland and forest environment. Its red color helps it to blend in with the trees. </u></em>
<em><u>The kit fox is sandy in appearance because it lives in the desert. It also has larger ears than the red fox and its larger ears help the fox release excess body heat in the desert.</u></em>
<u>Changes in inheritable physical or behavioural traits</u> due to changes caused by variations as the organism move from one generation to another.
In addition changes in selective pressures of their new environments in order to gain adaptions for survival in the new environment is another factor for this changes.
Predictions and warnings can also reduce damage and economic losses. When notice of an impending disaster can be issued well in advance, as it can for some riverine floods, wildfires, and hurricanes, property and natural resources can be protected.
