Answer:
1.
Nearly all helium on Earth is a result of radioactive decay. The decay product is primarily found in minerals of uranium and thorium.
In what is called radioactive emission of "alpha particles" the atom of, say uranium, spits out particles in the form of two protons and two neutrons--a helium nucleus.
2.Helium is obtained through natural gas as it is extracted from the ground. The helium is a result of the decay of thorium and uranium. As these elements decay, they release an alpha particle. That alpha particle is the nucleus of a helium atom.
3.Natural gas is separated into its major components through a distillation process known as fractional distillation. Sometimes this name is shortened to fractionation, and the vertical structures used to perform this separation are called fractionating columns. In the fractional distillation process, the nitrogen and methane are separated in two stages, leaving a mixture of gases containing a high percentage of helium. At each stage the level of concentration, or fraction, of each component is increased until the separation is complete.
Explanation:
Answer: One of the primary differences between DNA and RNA is that DNA is double-stranded while RNA is single-stranded.
The correct statement is that viruses are not living, although this concept is widely debated. In truth, viruses are neither living nor non living, they have not been classified properly as of yet. Viruses do NOT have organelles and they can NOT produce their own energy thus they rely on other cells to provide energy and to reproduce and spread the virus for them to other cells. (I'm fascinated by viruses, sorry i rambled!)
