Are there any non carbon based life forms?

No, and there is little chance that any planet anywhere in the Universe will have life not based on carbon. This is because carbon forms four bonds, is very common and the energies of carbon reactions are suitable.

Could there be nitrogen based lifeforms?

Nitrogen is one of a handful of elements that have been suggested as alternatives to carbon as the basis of life elsewhere in the universe. Principally this is because it can form long chains at low temperatures with a liquid solvent such as ammonia (NH3) or hydrogen cyanide (HCN).

Is every living thing carbon based?

Possibly the quickest answer to this question is simply that all living things are reliant on molecules that include carbon. There are no living things on our planet that do not have carbon (however, there are nonliving things made up of carbon as well: e.g, diamonds and, well, carbon itself).

What if humans were silicon based?

Due to the weak nature of silicon bonds, silicon-based life would be primitive and simple. The complex structures of the organic forms we see on earth would be lacking — instead we would see a blob or a clump of silicon compounds.

Are there sulfur based lifeforms?

Sulfur-based bacteria exist today, in places like hydrothermal vents and hot springs. And early Archaean rocks have shown evidence for ancient sulfur-based metabolism as early as 3.5 billion years ago, but fossils of these sulfur-based life forms have been difficult to find and even more difficult to verify.

Are there any silicon-based life forms?

So, the answer, at least for now, is no – although silicon can sometimes be used biologically as a sort of structural support (and there are some examples claiming silicon as an essential trace element) for carbon-based life – silicon-based life itself does not exist, as far as we know, because of the chemical and …

Why are humans called carbon-based lifeforms?

Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.

Are plants carbon based?

All living things are carbon based. The role then of carbon in plants is called the carbon cycle.

Why are humans made of carbon?

Carbon dioxide molecules can also enter red blood cells and bind to hemoglobin – a protein present in the blood that transports oxygen throughout the body. A molecule named carbaminohemoglobin is formed when carbon dioxide binds with hemoglobin. It accounts for 30\% of the total carbon dioxide present in the human body.

Are you really a carbon based life form?

You are -based life-form. Every organism on this planet, from fungus to the massive blue whale, has its genetic code written in carbon. The ability of carbon atoms to form many simultaneous bonds with other elements made it easy for them to bond with nitrogen, oxygen and hydrogen.

Why are humans carbon based life forms?

Carbon Based life forms often get their carbon from ingesting carbon based sustenance and from there the cycle keeps going, other organisms release the carbon back into the atmosphere and the cycle is continued. Humans can effect the way in which the carbon cycle operates in a devistating way.

Are humans made of carbon?

The element carbon is not found in a pure form in the human body, but rather in compounds within the body. Carbon constitutes roughly 18 percent of body mass, and millions of carbon atoms form the thousands of molecules in virtually every cell.
