Answer:
Explanation:
Helium is the second most abundant element in the universe, but here on earth, it's rather rare. Most people guess that we extract helium from the air, but actually we dig it out of the ground. Helium can be found in certain parts of the world, notably in Texas, as a minor component in some sources of natural gas.
Helium is generated underground by the radioactive decay of heavy elements such as uranium and thorium. Part of the radiation from these elements consists of alpha particles, which form the nuclei of helium atoms. ... Helium can also be produced by liquefying air and separating the component gases
When the gas contains more than about 0.4% helium by volume, a cryogenic distillation method is often used in order to recover the helium content. Once the helium has been separated from the natural gas, it undergoes further refining to bring it to 99.99+% purity for commercial use.
Answer:
The results of early research on biofeedback were surprising because they indicated that people could learn to control bodily functions regulated by the frontal lobes. b.somatic nervous system.
Explanation:
The frontal lobes have many funtions regarding memory, language, intelligence. It also has some motor skills because of the primary motor cortex, which helps coordinate voluntary movements, including walking and running. This could be named as the <em>somatic system, which transmits sensory communications and is responsible for voluntary movement and action. </em>
The answer is I, evolutionary phylogeny; It is based on the phylogeny of organisms which is determines the similarities and differences in their physical or genetic characteristics. A phylogenetic tree or evolutionary tree is used which shows the inferred evolutionary relationships among various biological species or other entities.
