A. DNA molecules consist of two strands of a helical chain of nucleotides, which are the monomer subunits of DNA.
B. Nucleotide subunits that make up a DNA strand are polar due to the presence of the phosphate group per subunit.
C. There are only four different nucleotides in a DNA strand. The nucleotides are different from each other based on the four nitrogen bases. These are adenine, thymine, cytosine, and guanine.
D. Hydrogen bonds are present between the nitrogen bases of nucleotides from anti-parallel DNA strands. Phosphodiester bonds, on the other hand are present between nucleotides of an individual DNA strand thus holding one DNA molecule together.
just remember that osmosis is water
Agricultural practices relating to irrigation have the tendency to reduce the water level of river basins.
<h3>What are the effects of irrigation agriculture on river basins?</h3>
Irrigation agriculture requires that crops are watered artificially and this requires a water source. Hence, waters in river basins suffer and this leads to a reduction in their levels.
Water quality is impacted by agricultural practices such as the use of agrochemicals and fertilizers. Agrochemicals are washed into water bodies and this impacts biodiversity life in water.
One conservation strategy to reduce the impact of this kind of agricultural practice would be to practice organic farming. A farming practice that is devoid of using agrochemicals or the ones that are not poisonous to biodiversity and are biodegradable.
