What else can I help you with?
What would have to the oxygen content in the air if photosynthesis were stop?
The oxygen content in air would have decreased. This is because photosynthesis is a process which keeps the balance between oxygen and carbon dioxide by converting carbon dioxide to oxygen.
What type of chemical bond would be formed between oxygen and hydrogen atoms?
A covalent bond would be formed between an oxygen and hydrogen atom. This bond is formed by the sharing of electrons between the atoms.
Could the world exist without chlorophyll?
not in the way we know it, as although the world would exist, there would only be few simple organisms, which even then, wouldn't thrive all that much. In other words, the world would be covered in carbon dioxide, and the only life would be amoeba.
Did organisms that require oxygen exist before photosynthetic organisms?
It would be impossible for oxygen requiring organisms to exist before photosynthetic organisms because there was not oxygen in the atmosphere for these organisms to breathe. Photosynthetic organisms take carbon dioxide and water in and create oxygen as waste. Before these photosynthetic organisms existed there was not enough or any oxygen in the atmosphere for organisms requiring oxygen to survive.
What are the chemistry symbols for oxygen and water?
The atomic symbol for oxygen is O. The chemistry symbol for water is H2O. Water covers about 70 percent of our planet & is needed to support life. Without it, we would not exist.
What if oxygen didn't exist?
No one would be here today if there was no oxygen.
What would happen if oxygen did not exist?
Life on Earth, or at least most of it, would not exist without free oxygen. It is possible that some other form of life, based on another element, could exist in a non-oxygen environment. But none has been discovered as of now.
How is oxygen important to society?
nothing on earth would exist
Could life exist on Earth if the air contained only oxygen?
No. The oxygen would be too concentrated and we would die.
Why does your body need oxygen to function?
we need oxygen to function because without oxygen we would suffocate to death. without oxygen we wouldn't exist right now.
What are example of diatoms?
An example of a diatom (also known as bacillariophyta) would be cyclotella.
What would happen if there was no hydrogen and oxygen in water?
Water is a compound made up of two hydrogen atoms and one oxygen atom bonded together. If there were no hydrogen and oxygen in water, it would not exist as a substance. The properties and characteristics of water, such as its liquid state, transparency, and ability to dissolve other substances, depend on the presence of hydrogen and oxygen.
A force of attraction would exist between what two subatomic particles?
A force attraction exist between a protons and a neutron
How would we survive without the atmosphere?
Without the atmosphere, Earth's surface would be exposed to the full force of the sun's radiation and we would not have oxygen to breathe. Temperatures would fluctuate drastically between day and night and protection from meteoroids would be limited. Life as we know it would not be able to exist without the atmosphere.
Would oxygen be present if water did not exist?
no 70 percent of all oxygen comes from algee and 100 percent of plants are decendant of algee
The key elements for a fire?
Fuel, Oxygen and Heat Fuel, Oxygen and Heat Fuel, Oxygen and Heat
What reasons would have made it difficult for life to exist on early Earth?
The lack of oxygen and the extreme temperatures
