Answer:
Using some dilutions of the mother solution
Explanation:
If there is a valid process by which the mother solution can be diluted with precision, the results must be in the range that are "normal".
If there are different dilutions that shows different results, but by graphing and extrapolating they show the same results as the mother solution, then the first measurement is correct.
This is also a method used to calibrate an instrument or to confirm the concentration of the mother solution.
check the graph.
Hope this info is useful.
Answer:
Question 1 answer
Plate tectonic began in 1915 when Alfred Wegener proposed his theory which was continental drift. Usually scientists use waves to study the difference of the layers of earth. They use seismic waves. seismic waves are generated by earthquakes or nuclear-test explosions.
Those 3 pieces would be the fit of the continents, paleoclimate indicators, and geologic features. The rock formations of eastern North America, Northwestern Africa and Western Europe were found later to have a common origin. They were found to overlap.
