Answer:
Two reasons why the use of synthetic fertilizers is not the answer to decreasing soil quality are:
- They increase the nitrate levels in the soil which is a rich supplement for nitrogen needed by plants for their growth.
- They are easily available and user-friendly but should be used in regulated amounts as an excess of nutrients like nitrogen and phosphorus present in synthetic fertilizers enter the aquatic ecosystem.
<u>Explanation:
</u>
Synthetic fertilizers are made up of three main nutrients, viz, nitrogen, potassium and phosphorus. All of these are required for the proper growth of plants. Though, these fertilizers give higher yields, yet their excessive use is bad for aquatic ecosystems.
When these fertilizers are used in excessive amounts, they reduce the dissolved oxygen in the water as there’s an increase of bacteria and algae in the water. That is why such fertilizers should be used in regulated amounts.

Explanation:
In the given case, in my opinion, one should perform the experiment in a similar manner with no change. An experiment is done many times in order to omit any influences of sampling or handling on the outcomes of the study. For this purpose, the repetitive experiments have to be performed in a similar way as the previous ones were performed. After that, the outcomes of the repetitive experiment and the initial one are compared.
If any conditions or variables are changed in the experiment, the outcomes of the repeated experiment cannot be compared with the initial one. As variations in experimental material, variables, or procedure would have influenced the outcomes.
The nurse should advice the patient to avoid intake of fluids before the surgery. This is the most likely intervention technique that would help avoid intra-operative complications, reduce cerebral edema, and prevent postoperative vomiting. The nurse should also prescribe the proper medication to ensure that the patient won't encounter any further problems after the operation.
