What else can I help you with?
What gas was not present in the atmosphere of primitive earth?
Primitive Earth (Before life) contained no or very little Oxygen (element#8)According to scientific theory:Earth had no oxygen to begin with. It had a lot of carbon dioxide, though. Somehow (We still do not know how they started growing) single-celled Carbon Dioxide-breathing bacteria slowly, over thousands to millions of years, turned most carbon dioxide into oxygen, supporting new types of life.:)
Which gas is lacking in the atmosphere of primitive earth?
Oxygen was lacking in the atmosphere of primitive Earth. Instead, the atmosphere was primarily composed of gases such as carbon dioxide, nitrogen, methane, ammonia, and water vapor.
What percent of life is in the Earth?
Roughly 70% of the Earth's surface is covered by water, which is home to a significant amount of life. However, most life on Earth exists in the oceans rather than on land.
In 1953 who recreated the conditions of early Earth inside a laboratory apparatus?
Stanley Miller, along with Harold Urey, recreated the conditions of early Earth inside a laboratory apparatus in 1953. They aimed to demonstrate how life could have originated from simple molecules in a primitive Earth environment.
Does all life on earth exist in the ionosphere true or false?
False. Most life on Earth exists in the biosphere, which includes the surface of the planet and areas where organisms can live. The ionosphere is a region in the Earth's upper atmosphere that is much higher than where most life exists.
Where was the birth place of primitive life-form on earth?
The oceans, probably. most def the oceans
What is the most primitive bacteria called?
The most primitive bacteria are known as cyanobacteria, also called blue-green algae. They are often considered to be some of the earliest forms of life on Earth and are capable of photosynthesis.
Why are scientists who are searching for life on other planets studying Archae bateria?
Archaebacteria are the oldest and most primitive forms of life on planet Earth. It is postulated that primitive life on other planets would be most likely to resemble Archaebacteria. In addition, Archaebacteria were the first life forms to exist on Earth, so studying them allows xenobiologists to postulate how life may come into being on other planets.
Is RNA a thought to be the oldest and most primitive coding mechanism for life?
Yes it is the oldest and most primitive coding mechanism
The first cells to evolve in primitive earth were most likely members of the domain?
The first cells to evolve in primitive Earth were most likely members of the domain Bacteria. These cells were prokaryotic, lacking a true nucleus, and could survive in extreme environments. Their simple structure and ability to adapt to various conditions allowed them to thrive and serve as the foundation for life on Earth.
Is the sun the source of energy in most energy resources?
The Earth has two sources of energy, the sun's radiation and heat from inside the Earth. The sun is most important and life could hardly exist except at a very primitive level without it.
Can the box jellyfish see?
No, jellyfish do not see. They have no eyes, and no brains either. They are extremely primitive organisms, the most primitive of all existing multicellular life.
What geological period has fossils of the most primitive life forms?
20,000 b.c.
What is the most primitive portion of the brain?
The brainstem, consisting of the medulla, pons, and midbrain, is considered the most primitive portion of the brain. It controls basic life functions such as breathing, heart rate, and swallowing.
Was Earth colonized by extraterestrial man when there where primitive man on Earth?
No.
What is the superlative form of the word primitive?
most primitive
