Explain how and why GISs were developed and first used and how they are used today.​
frosja888 [35]

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.

The photosynthetic pigments bacteriorhodopsin and proteorhodopsin are present in ________ and ________, respectively. The photos
DaniilM [7]

Answer:

A. Archaea / Bacteria

Explanation:

Bacteriorhodopsin is a protein used by Archaea, most notably by halobacteria, a class of the Euryarchaeota. It acts as a proton pump; that is, it captures light energy and uses it to move protons across the membrane out of the cell

Bacteriorhodopsin is an integral membrane protein usually found in two-dimensional crystalline patches known as "purple membrane", which can occupy up to nearly 50% of the surface area of the archaeal cell.

Proteorhodopsin also known as pRhodopsinbis a family of over 50 photoactive retinylidene proteins, a larger family of transmembrane proteins that use retinal as a chromophore for light-mediated functionality, in this case, a proton pump

List molar concentrations (0.0 M, 0.2 M, etc.) at which water entered the potato strips. Why did water move into the potato stri
kati45 [8]

Answer:

- Water entered the potato strips because the potato cells contained higher concentration of solutes than its external environment.

- The solutions are hypotonic to the solution in the potato cells.

Explanation:

According to osmosis, water will move from a region where it is high in concentration to that region where it is low in concentration. However, a region with high solute concentration contains a low water concentration and vice versa.

Hence, according to this question, water is said to move into potato strips from solutions of molar concentrations like 0.0M, 0.2M etc. Water moved into the potato strips because potato cells contained higher concentration of solutes than its external environment. This means that the external solutions are HYPERTONIC i.e. low in solute concentration to the solution in the potato strips.
