How does concentrated nitric acid affects water samples containing mercury?
Mercury (as a metal) is soluble in concentrated nitric acid.
Where to get music samples?
Maybe from DJMixsource.com and other related sites. Maybe you want to extract them from an old tape, or some mp3 files. In the stores you may find CDs containing special effects and samples. Anyway, there are a lot of places where you can get samples. I hope this answer helps you :)
How do you dissolve silica containing samples without using Hydrofluoric acid?
Silica-containing samples can be dissolved using a mixture of hydrochloric acid and nitric acid. Another option is to use a mixture of sulfuric acid and hydrochloric acid. Strong bases like sodium hydroxide can also be used for dissolving silica, though this may require elevated temperatures.
What are the Estimation of mercury in biological samples?
The estimation of mercury in biological samples is typically done using techniques such as atomic absorption spectrophotometry or inductively coupled plasma mass spectrometry. These methods involve digesting the biological sample to release the mercury and then measuring its concentration. Calibration curves with known standards are used to quantify the amount of mercury present in the sample.
Why clinical trials can't be done on human tissues?
The tissue samples are not alive. They are not living or moving like a living human. The effects of the drugs may be different on 'non living' samples may be different to the effects on a non-living human.
What was the name of the spacecraft that was to return a capsule to Earth containing samples of dust from a comet's tail?
Stardust. The spaceships name was Stardust.
Why clinical trials can't be done on human tissue samples only?
Clinical trials require studying the effects of a treatment in a living organism to understand its overall impact, including potential side effects and interactions with other bodily systems. Human tissue samples lack the complexity of a functioning organism, meaning that critical information about how a treatment interacts with the body as a whole would be missed.
What substance was used to treat the DNA before placing the samples into the wells?
To treat the DNA before placing the samples into the wells, a loading dye containing substances like glycerol and bromophenol blue is commonly used. The loading dye helps to visualize and track the DNA samples as they move through the gel during electrophoresis.
Why can't clinical trials be done on human tissue samples only?
The tissue samples are not alive. They are not growing/moving like a living human so the effects the drugs have on the non living samples may be different to the effects on a living human.
Water samples that contain dissolved substances are known as?
Water samples containing dissolved substances are known as solutions. The substances are dissolved in the water, resulting in a homogeneous mixture where the particles are evenly distributed.
How would three radioactive samples affect you if you were allowed to handle it?
It depends upon what the radioactive samples are. If you handle a glow-in-the-dark wristwatch, then there will be no observable effects. If you handle a 'hot' piece of Cesium, say, you could lose your arm.
How do you extract DNA from blood samples?
To extract DNA from blood samples, the blood is first treated with a solution to break open the cells and release the DNA. The DNA is then separated from other cellular components using techniques like centrifugation or filtration. Finally, the DNA is purified and concentrated for further analysis or testing.
