s344n2d4d5 [400]

<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.

(a) if the seawater carbonate ion concentration is 270 ?mol/kg, what is the approximate rate of calcification, and approximately
Travka [436]
Using the graph provided with the question, we are able to find that that for a concentration of 270 micromol per kilogram, the calcification rate is 20 mmol calcium carbonate per meter squared per day.

Using this calcification rate,
30 = 20 * 1 * days

days = 1.5

The deposition will require 1.5 days.

kipiarov [429]

Digestive enzymes help to break down food in its simplest form. Pepsin is a digestive enzyme which leads to the degradation of proteins in the stomach. It is produced as pepsinogen and converted to active pepsin in the stomach by the removal of several amino acids.

<h3>What is pepsin?</h3>

Pepsin is a digestive enzyme which is present mainly in the gastric juice in stomach and helps to breakdown protein into peptides.

This pepsin is present in the stomach in the form of inactive pepsinogen. This pepsinogen gets active in the stomach by the action of hydrochloric acid.

Pepsinogen gets active and forms pepsin.

Thus, it can be concluded that the digestive enzyme pepsin degrades protein in stomach and is synthesized as pepsinogen and gets converted into active pepsin in stomach by removal of several amino acids.
