<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:

Hypotonic solution

Explanation:

hypertonic solution is the one you get when the solute concentration of the water is higher than that of the cells.

isotonic solution is the one you get when the solute concentration of the cell and the water are the same.

hypotonic is the one that you get when the solute  concentration of the cell is higher than that of the waters.

Solute concentration being low reminds me of water. Hypo kind of sounds like hippo and hippos love water. You can use this to memorize the difference between hypertonic and hypotonic solutions.

sorry if the grammer is bad i tried my best.
