Which gas became part of earth's atmosphere mainly as a result of the evolution of life-forms?
Oxygen became a significant part of Earth's atmosphere due to the evolution of photosynthetic life forms, such as cyanobacteria and plants. These organisms produce oxygen as a byproduct of their metabolic processes, leading to the rise of oxygen levels in the atmosphere over time.
What gas became part of Earths atmosphere mainly as a result of the evolution of life-forms?
Oxygen became part of Earth's atmosphere mainly as a result of the evolution of life forms, particularly through photosynthesis by early cyanobacteria and plants. This process involved converting carbon dioxide into oxygen as a byproduct, leading to the oxygen-rich atmosphere we have today.
Which gas in Earth's atmosphere suggests that there is life on Earth?
The presence of oxygen in Earth's atmosphere suggests there is life on Earth. Oxygen is produced primarily by plants and certain bacteria through the process of photosynthesis. Its abundance indicates the ongoing presence of life forms that release oxygen as a byproduct of their metabolic processes.
What type of bond forms between barium and oxygen?
An ionic bond forms between barium and oxygen.
Which gas forms 21 percent of the Earth's atmosphere?
Oxygen forms 21 percent of the Earth's atmosphere.
Could a cell live without a mitochondria?
Yes. Not yours, but there are plenty of life forms the do not require oxygen.
How would oxygen affect the earth if it was removed?
If oxygen were to be removed from earth, all life forms that require oxygen to survive will die out leaving the earth as we know it baron. Oxygen is vital to our survival, without it we would die.
Do aliens need oxygen?
It is not known for certain whether aliens, if they exist, require oxygen. Life as we know it on Earth relies on oxygen for respiration, but there may be forms of life in the universe that have evolved to utilize different elements or means for survival.
What form of respiration was probably used by the earliest forms of life?
The earliest forms of life likely used anaerobic respiration, which does not require oxygen to produce energy. This process is less efficient than aerobic respiration but can still generate ATP for cellular processes.
Is cyanobacteria live in mars?
Well. Cyanobacteria were the first life forms on Earth that did not require oxygen to breathe. I think there is probably life on Mars. But I don't really know for sure. But if there is life on Mars, it probably would be microscopic as cyanobacteria.
How do you know if your from out of this world?
When you don't require oxygen to maintain life.
How many life forms do not rely on oxygen?
50 billion
Where does oxygen come from and why is it important to life on earth?
Oxygen is important as it the breathing sources. It also forms ozone which is vital for life on earth.
Why there is no creatures on Mars?
It is un suitable for life forms, since there is no oxygen.
Do artificial oxygen cause cancer?
Oxygen is oxygen no matter how it is created. Oxygen is essential for many life forms so it is safe to say it is not a carcinogen.
Was earths first cells aerobic or anaerobic?
No, not all forms of life on Earth require oxygen in their environment. There are forms of life, called anaerobic forms, that do not require oxygen. These animals belong to the phylum Loricifera.
Why do scientists say that all forms life depend on solar energy?
Plants require sunlight to grow. Other forms of life eat plants.
