Hydrogen bonds are classified as weak because they are formed fast, but they also break easily under normal biological conditions.
Weak bonds can be easily broken, but this is extremely important because they are in bold in biological systems. For example, they help to decide and stabilize the shapes of water molecules.
Answer:
A. Populations of native wetlands plants will recolonize the land.
Explanation:
From many years' wetlands are converted into farmlands as they provide retention of soil, proper food and clean water, and the cycling of nutrients. But wetlands should not be permanently converted<em> because it can increase the load on soil and add pollutants (pesticides or fertilizers) in the soil and groundwater.</em>
If the farming stops and water flows on the land again, the native plants present in wetlands will help to recolonize the land which is disrupted by farming activities.
Hence, the correct option is A.
Rivers and streams erode the land as they move from higher elevations to the sea. Eroded materials can be carried in a river as dissolved load, suspended load, or bed load. A river will deeply erode the land when it is far from its base level, the elevation where it enters standing water like the ocean.
