Answer:
we can reach the same conclusions by applying different experimental and observational procedures
Explanation:
The scientific method is a process that can be summarized in the following steps: 1-to raise a question, 2-to make a hypothesis, 3-to obtain data from observations and/or experiments, and finally, 4-to obtain conclusions that enable to confirm (or reject) the hypothesis. The scientific method is flexible because it is not necessary to follow 'stringent' guidelines in order to reach the same conclusions. In consequence, the predictions derived from such results can be tested again to determine the veracity of the results.
The correct answer Organism
<span>MgSO4 and Sr(NO3)2 are both soluble, so the ionic equation would look like this.
Mg+2 + SO4-2 + Sr+2 + 2NO3-1 ---> Mg+2 + 2NO3-2 + SrSO4
SrSO4 is insoluble. Now Mg and 2NO3 are on both sides, so cross them out, the net ionic equation is
SO4-2 + Sr+2 ----> SrSO4</span>

Evaporation. People have been doing that since ancient times to get salt from sea water.
