The answer is going to be the line equation to predict the cost of gas per gallon in 2017 n
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.

Answer:
The answer is D. Prokaryotes have one origin of replication but it proceeds in two directions.
Explanation:
DNA replication is a process in which in which one parental DNA strand acts as template to synthesize complementary daughter strand. There are specific sequences in DNA from where replication starts. These sequences are called origin of replication. In Eukaryotic cells due to large number of DNA many origins of replication are present. However, in prokaryotic DNA only one origin of replication is present that is bi-directional.
Because lower salinity is the only thing he reproduced, in a large ecosystem such as the Atlantic Ocean there are a variety of factors that can influence the development of eggs.
