The mining causes the dust emission, which increase the amount of the particulate matter in the environment and causes the air pollution. The pollutants may include sulfur and nitrogen compound, which may cause acid rain and drainage. The removal of the material from earth may lead to erosion of the soil and may cause land slides.
I believe that the reason for using taq polymerase for pcr is that; it is heat stable and can withstand the temperature changes of the cycler. Taq polymerase is isolated from a heat loving bacterium that is naturally found in hot springs, so the enzyme doesn't break down at the high temperatures necessary for copying DNA using a polymerase chain reaction. At high temperatures, Taq polymerase attaches nucleotides to a DNA template, thereby copying the DNA.
Answer:
These are Cowpers's gland.(Bulbo Urethral Gland)
Explanation:
These are small pea-sized glands at the base of the penis which connect each with the urethra through a short duct. It is thorough this ducts that secretion from each gland gets to the urethra.
