How would a volcano erupt in an oxygen free environment?
it can not
What is an anaerobe?
An anaerobe is an organism that thrives in an environment without oxygen. Facultative anaerobes prefer an oxygen-free environment but can survive in the presence of oxygen. Obligate anaerobes are destroyed by oxygen and cannot survive if it is present in their environment.
Is oxygen mixture or pure substance?
Oxygen is a pure substance. In nature, free oxygen exists as a molecule of two oxygen atoms covalently bonded, O2.
Is regular and free election a characteristic for limited or unlimited government?
A limited government is usually termed to describe one where there is less government intrusion in the rights of its citizens. It provides the environment for free and open elections on the basis of the rule of law. On the other hand, an unlimited government has indeed, no limits in its authorities and by its very nature can disrupt the conduct of free and open elections.
An oxygen free environment is?
An oxygen free environment may be described as "anoxic" (without oxygen) however the composition of gases in the remaining gases may better describe it:A gas composed of noble gases like argon is called inertA gas which would unite with oxygen or other oxidants is a reducing atmosphereAn atmosphere similar to the Earth;s atmosphere but without oxygen is anaerobic
What is the meaning of anerobic?
A life-form that lives in an oxygen-free environment is described as "anaerobic."
Why are Alkaline metals not found free in nature?
Alkali metals are highly reactive due to their tendency to lose an electron, which makes them prone to forming compounds with other elements rather than existing in their pure, free state in nature. They readily react with moisture, oxygen, and other substances in the environment, which prevents them from being found free in nature.
Why was oxygen absent from earth's early atmosphere?
Oxygen is an extremely chemically active element, which is why things can burn in our current atmosphere. In the early Earth, all the oxygen had reacted with other chemicals in the environment, so that there was no free oxygen. Only later, when photosynthesis was used by green plants, was there a source of free oxygen.
How do you know that the first living thing did not require oxygen?
Scientists infer this by studying the evolution of life on Earth. The first living organisms likely evolved in an anaerobic (oxygen-free) environment, as oxygen levels were not initially present in significant amounts on Earth. These organisms would have been adapted to survive in environments without oxygen, and the need for oxygen likely evolved later as more complex organisms developed.
The oxygen revolution changed Earth's environment dramatically What adaptations took advantage of the presence of free oxygen in the oceans and atmosphere?
the evolution of cellular respiration, which used oxygen to help harvest energy from organic molecules
List two forms of anerobes?
* 1.) Obligate Anaerobes (can live only oxygen-free environment)* 2.) Facultative Anaerobes (can live oxygen including environment, but makes anaerobic fermentation)
What must photosynthetic bacteria provide before any eukaryotes could evovlve?
Oxygen. Photosynthetic bacteria were essential in producing oxygen through photosynthesis, which created an oxygen-rich atmosphere. This new oxygenated environment allowed for the evolution of aerobic metabolism in eukaryotes.
