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.
Answer/Explanation:
In eukaryotes, photosynthesis occurs mainly in green plants. These organisms have specialized organelles called chloroplasts that carry out photosynthesis. These contain photoreceptors that absorb photons from the sun through a pigment called chlorophyll, providing the energy to synthesise glucose from carbon dioxide and water.
In contrast, prokaryotes that carry out photosynthesis are able to do so because they have folds in the plasma membrane that permit the attachment of chlorophyll. They do not have specialized membrane-bound organelles like eukaryotes.
I think the correct answer from the choices listed above is option D. Destruction of tundra vegetation will likely result in melting of the permafrost. The tundra ecosystem is extremely sensitive to disturbance with little ability to restore itself. The melting of the permafrost will <span>cause the collapse of ground and loss of soil. </span>
Answer:
Bio gas
Explanation:
Bio gas is gotten from the anaerobic breaking down of biomass especially animal waste.
PROS:
A. it is renewable: biogas is renewable and has an endless supply of material since animals are the main source when compared to fossil fuels.
B. It doesn't involve a rigorous mining exersice to get to like fossil fuels and it is in accessible abundance.
CON:
A. A lot of waste is needed for the product of biogas and the final waste (sludge) from the production process can be a huge problem to dispose off.
B. Some of the gases liberated in the manufacturing process are greenhouse gas, especially methane. These gases if let out, will contribute immensly to global warming.
