Answer:
How is the hydrosphere changing? Human contributions to greenhouse gases in the atmosphere are warming the earth's surface – a process which is projected to increase evaporation of surface water and accelerate the hydrologic cycle. In turn, a warmer atmosphere can hold more water vapor
Wetlands are often drained in many regions to facilitate human use of the land. This happens a lot within the Pairie Provinces of Canada, where wetlands are drained to make way for agriculture. Wetlands are also often drained so as to use the land for building houses. Humans have also altered the flow of rivers through constructing dams and over-abstracting water. In many regions, depressions that would have been flooded in the past to form wetlands are no longer saturated. Wetlands also act as a 'sink' for many pollutants, and much of the pollution released into upstream rivers by humans may settle into the relatively stagnant waters of wetlands, to be absorbed into the sediments, where often it acts as a chronic pollutant, negatively effecting the aquatic ecosystem and water quality downstream.
Answer:
True
Explanation:
The biomolecules are the macromolecules composed by the polymerisation of small units called monomers. Since the biomolecules are the molecules in which both the covalent and noncovalent bonds are present.
Both covalent and non-covalent bonds stabilize the structure of the biomolecule like in DNA the phosphodiester bond between the two nucleotides but the DNA also contain the non-covalent bonds like hydrogen bonds between the base pair which allows the complementary base pairing a stabilizes the helical structure of DNA.
Thus, True is the correct answer.
