<u>Answer</u>: C) They can find the neighborhoods that are in the most danger, where to set up shelters, and which routes will help people reach safety.
<u />
<u>Explanation</u>: GIS is an extremely useful tool in analyzing geographic information. By overlaying topographic data as well as infrastructure, populations, bio-physical datasets (e.g. flood, landslide, storm surge, earthquake data), vulnerable areas as well are relatively safe areas can be detected. Thus, routes to safety as well as shelter construction can be planned.
The strength of an earthquake as well floodwater depth cannot be determined in advance with GIS. The bio.physical datasets that are used come from events that have already occurred and not future events. With GIS the damage caused by a future even can be <em>estimated</em>, but the strength of the natural disaster itself cannot.
Answer:
c.All are halogens, so they are not very chemically active,
The Hertzsprung-Russell diagram is one of the most important tools in the study of stellar evolution. Developed independently in the early 1900's by Ejnar Hertzsprung and Henry Norris Russell, it plots the temperature of stars against their luminosity (the theoretical HR diagram), or the color of stars against their absolute magnitude
Depending on its initial mass, every star goes through specific evolutionary stages dictated by its internal structure and how it produces energy. Each of these stages corresponds to a change in the temperature and luminosity of the star, which can be seen to move to different regions on the HR diagram as it evolves. This reveals the true power of the HR diagram – astronomers can know a star’s internal structure and evolutionary stage simply by determining its position in the diagram.
The Hertzsprung-Russell diagram the various stages of stellar evolution. By far the most prominent feature is the main sequence (grey), which runs from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) of the diagram. The giant branch and supergiant stars lie above the main sequence, and white dwarfs are found below it.
Answer:
Sickle cell anemia is a genetic disease with severe symptoms, including pain and anemia. The disease is caused by a mutated version of the gene that helps make hemoglobin — a protein that carries oxygen in red blood cells. People with two copies of the sickle cell gene have the disease.
