Answer:
There are number of methods for determining the fingerprints. However, most commonly used methods are:
- Photography
- Alternate Light Source
- Cyanoacrylate
Explanation:
Determination of fingerprints is an important method used in forensic science. There are generally three types of fingerprints that are to be determined, namely latent fingerprints, patent fingerprints and plastic fingerprints. There are numerous methods used for the determination of fingerprints. However, most commonly used methods are:
<u>Photography:</u> Photography is direct or straightforward method that is used to determine the patent fingerprints. The image is photographed in a high resolution with the help of forensic measurement scale used as a reference.
<u>Alternate Light Source Method:</u> In this method the light source or LED is used of a particular wavelength in order to determine the latent fingerprints.
<u>Cyanoacrylate:</u> Cyanoacrylate processing is also known as super glue method or fuming method, which involves exposure of cyanoacrylate vapors to the non-porous surface from where the fingerprints are to be obtained.
More than 90% on the crust is composed of silicate minerals. Most abundant silicates are feldspars<span> (</span>plagioclase<span> (39%) and alkali feldspar (12%)). Other common silicate minerals are </span>quartz<span> (12%) </span>pyroxenes<span> (11%), </span>amphiboles<span> (5%), micas (5%), and clay minerals (5%).</span>
Part 1;
Because there is only limited amounts of fresh water on the Earth the rest is salt water; which humans can not survive on as the salt dehydrates our bodies instead of hydrates.
1) The more we try to get the the fresh water the more we will likely make more pollution.
2) The more we use the less there is.
3) Everything needs water.
Part 2; no idea I believe it is the ice caps, as it is fresh water in the ice caps and not a lot of humans up there to pollute the runoff.
