Gene duplication played a critical role in evolution in that it produces redundant copies of existing genes, which are then free to mutate and adopt new functions. it is a major mechanism in which new genetic materials are generated during molecular evolution. Gene duplication is important in that it can provide new genetic material for mutation, drift and selection to act upon, which results in specialized or new gene functions.
Answer:There are two conditions that must be met for an object to be in equalibrium.
Explanation:1. The first condition is that the net force of the object must be zero for the object to in equalibrium.
2.If net force is zero then net force along any direction is zero.
<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.
