Answer:
The history of GIS all started in 1854. Cholera hit the city of London, England. British physician John Snow began mapping outbreak locations, roads, property boundaries, and water lines.
John Snow’s Cholera map was a major event connecting geography and public health safety. Not only was this the beginning of spatial analysis, but it also marked the start of a whole field of study: Epidemiology – the study of the spread of disease.
To this date, John Snow is known as the father of epidemiology. The work of John Snow demonstrated that GIS is a problem-solving tool. He put geographic layers on a paper map and made a life-saving discovery.
Explanation:
Earth's long-term warming trend can be seen in this visualization of NASA's global temperature record, which shows how the planet's temperatures are changing over time, compared to a baseline average from 1951 to 1980. The record is shown as a running five-year average.
Answer:a
a possible explanation for this occurrence is that a test tube or dropper was accidentally used repeatedly without being sterilized, causing sample cross-contamination. DNA in this test case did not confirm that the father of the second child was another client of the fertility clinic who had never met the mother...therefore this is a possibility.
Explanation:
Answer:
The correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.
Explanation:
For the majority of the solids dissolved in water, the solubility increases with temperature increments. Higher temperatures accompany the increase in kinetic energy permits the solvent particles to more adequately break apart the solute atoms that shows intermolecular attractions.
So if glass one dissolves the salt faster than glass two then it is clear that glass one has more temperature than glass two that takes more time to dissolve the rock salt.
Thus, the correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.
