What earliest photosynthetic organism is responsible for the production of large quantities of oxygen in our atmosphere?
The earliest photosynthetic organisms responsible for the production of large quantities of oxygen in our atmosphere are cyanobacteria. These microorganisms, which emerged around 2.5 to 3 billion years ago, conducted photosynthesis and released oxygen as a byproduct. This process significantly contributed to the Great Oxygenation Event, drastically altering Earth's atmosphere and enabling the evolution of aerobic life forms.
What else can I help you with?
Is iron a part of the atmosphere?
Yes it is, but in small quantities.
What material contributed least to the early composition of the atmosphere?
Helium contributed least to the early composition of the atmosphere, as it is relatively rare and not produced in significant quantities by natural processes on Earth.
What are places that xenon is found in?
Xenon is found in the Earth's atmosphere in very small quantities (about 0.000009% by volume). It is also present in trace amounts in certain minerals and springs. Xenon is commercially extracted from the atmosphere through a process called fractional distillation of liquid air.
What is cloud seeding and is it effective?
Cloud seeding - is dropping quantities of microscopic particles into the upper atmosphere - with the intention that water molecules will 'stick' to the particles - and thus create rain.
If the phosphorus burn in atmosphere air?
When phosphorus burns in the atmosphere, it reacts with oxygen to form phosphorus pentoxide (P₂O₅) or phosphorus trioxide (P₄O₆) depending on the form of phosphorus used and the conditions of combustion. This reaction produces a bright white flame and can emit white smoke as the phosphorus oxide forms. The combustion can release energy and result in the production of heat and light, making phosphorus a reactive element in the presence of air. Additionally, the resulting oxides can contribute to environmental issues if released in significant quantities.
What prokaryotic cells that were the first to add significant quantities of oxygen to Earth's atmosphere are classified as?
Prokaryotic cells that were the first to add significant quantities of oxygen to Earth's atmosphere are classified as cyanobacteria. Cyanobacteria are photosynthetic bacteria that played a crucial role in the Great Oxidation Event, releasing oxygen as a byproduct of photosynthesis. Their activity contributed to the oxygenation of Earth's atmosphere and paved the way for the evolution of aerobic life forms.
What oxidized metal caused substantial quantities of oxygen to accumulate in Earth's atmosphere?
Iron was the oxidized metal that caused substantial quantities of oxygen to accumulate in Earth's atmosphere, a process known as the Great Oxidation Event. This event occurred around 2.4 billion years ago as photosynthetic organisms began producing oxygen through photosynthesis, which reacted with iron in the oceans and rocks, leading to the buildup of oxygen in the atmosphere.
which quantities define momentum?
The quantities of production in mass of a particle with velocity describe momentum.
Is iron a part of the atmosphere?
Yes it is, but in small quantities.
A gas which is not found in theatmosphere in significant quantities is?
One example of a gas not found in significant quantities in Earth's atmosphere is neon. Neon is a noble gas that is present in trace amounts in the atmosphere, but not in significant enough quantities to contribute to its composition.
Are there any atmospheric gases on Mercury?
Yes, but in very small quantities. Very very small quantities, Mercury's atmosphere is basically a vacuum.
What the axes of the production possibility frontier measure?
quantities of productive inputs
Why do scientists think that the first organisms did not need oxygen to survive?
Breathable oxygen, or O2, did not exist in large quantities in the atmosphere until after the evolution of photosynthetic organisms. Hence, early organisms had to have an anaerobic metabolism, or one that did not require oxygen. However, compounds containing oxygen, such as water, have always been necessary to organisms.
Which gas is present in very large quantities in the atmosphere?
The most abundant is nitrogen.
What gas can protect atmosphere?
Ozone, although in large quantities it can also be poisonous.
What was the gases percentage in the early atmosphere?
In the early Earth's atmosphere, which formed around 4.5 billion years ago, the composition was primarily made up of nitrogen (about 70-80%), carbon dioxide (around 10-20%), and smaller amounts of water vapor, ammonia, and methane. Oxygen was almost absent, as it was not produced in significant quantities until the advent of photosynthetic organisms. Over time, the atmosphere evolved, particularly after the Great Oxygenation Event, which increased oxygen levels significantly.
An athlete produces large quantities of sweat as a result the kidneys change the rate of urine production?
An athlete produces large quantities of sweat as a result the kidneys change the rate of urine production. This is because decreased urine production increases the amino acids in the blood.
