Answer:
false
Explanation:
Although the majority of the air we breathe is N2, most of the nitrogen in the atmosphere is unavailable for use by organisms. This is because the strong triple bond between the N atoms in N2 molecules makes it relatively unreactive. However organisms need reactive nitrogen to be able to incorporate it into cells.
The combining form cancel/o-, as in cancellous bones structures means: lattice structure.
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.
Alot of humans might not now they are even harming the systems by smoking or littering.
