There are quite a few molecules that must form for life to exist. One of these life-supporting molecules is water.
Atoms are the smallest forms of life. So they are the basis of life as we know it. Then there are molecules. Molecules are built up of two or more atoms. So basically atoms and molecules are connected because atoms make up molecules.
Because the conditions for it to emerge were favourable on pre-biotic Earth. The exact conditions required and the process by which life emerged are the domain of the field of research called abiogenesis.
I asked this question, but finally found some type of answers on the web (I am no biologist, bio-chemist or w/e): Mycoplasma has 15 molecules: http://www.bio.tamu.edu/COURSES/biol213/09spring/213homework1answerkeysp09.pdf Some experiment created a 8 molecule life form: http://www.evolutionofdna.com/Eight-Molecule-Life.html I still would like to get more information, maybe a nanobe has less molecules if it is a life form (as the pdf mentioned above proved it could not be a life form since a Ribsome DNA could not fit in a nanobe). Thanks
Because self replicating molecules are required in order for reproduction of genes to take place.
Carbon is important to life because it can form complex molecules. This is because because of its ability to form many bonds. Carbon typically has four single bonds, two double bonds, one triple and one single bond, or one double and two single bonds. Due to this extensive boding, carbon can form large molecules that are necessary for the existence of living things.
Water must exist in order for any form of life to live on earth.
There is no reason why a form of life doesn't exist on Mars. If life can exist in the very hot thermal vents deep in the earth's oceans, then why life in some form can't exist on another planet in some form?
No, it is too hot for complex molecules to exist.
synthesis
By chemical reactions they form other compounds. They are the base of life.
We know of no form of life that could exist on Saturn based on our current knowledge of life, Saturn, and the realities of the solar system.No
Since the center of the Earth is in the molted form, it can not support life. Thus, it is not possible for life to exist on the center of the Earth.
In life insurance it exist at the date on proposal form orat the inception
water
Currently, there is not.
Yes, but they might not be the SAME water molecules. Life (chlorophyll) splits water and animals make water from its components.
The gametic life cycle exists in which the haploid form is always unicellular as in humans.
