How do nitrates get into the surface water

Biology
1 answer:
loris [4]3 years ago
3 0
Natural levels of nitrate in Minnesota groundwater are usually quite low (less than 1 milligram per liter [mg/L] of nitrate-nitrogen). However, where sources of nitrate such as fertilizers, animal wastes, or human sewage are concentrated near the ground surface, nitrate may seep down and contaminate the groundwater. Elevated nitrate levels in groundwater are often caused by run-off from barnyards or feedlots, excessive use of fertilizers, or septic systems.

Wells most vulnerable to nitrate contamination include shallow wells, dug wells with casing which is not watertight, and wells with damaged, leaking casing or fittings.

Nitrate contamination of a well is often regarded as a first sign of deteriorating groundwater quality.

The factors which have shown variation are as follows -

  1. molecule size (large starch molecules vs. small glucose molecules)
  2. whether the molecules diffused through the membrane (tubing)

Explanation

Some factors with in the experiments remained constant from the point of starting of the experiment to its end. While some factors were varied to study its impact on the experiment rate of progression or on the final product formed. Thus , out of the following given factors, the ones that remained constant are -

  1. material used as the membrane
  2. amount of substances used
  3. number of trials

The factors which have shown variation are as follows -

  1. molecule size (large starch molecules vs. small glucose molecules)
  2. whether the molecules diffused through the membrane (tubing)

Semenov [28]

Answer:

Option B, They generally focus on one target insect to ensure that the target insect population remains low.

Explanation:

Biological pest control methodologies are focused towards a specific species of pest and do not harm the non-targeted species. These methods are environment friendly and do not produce any harmful residues. Also they do not develop any kind of resistance in species due to which the same bio pesticide can be used again and again. Since these methods have high specificity, they may require usage of two or more bio pesticides all together.  

Hence, option B is correct
