We all know the meaning of life in a single word: survival.

But that doesn’t make for an interesting question since the survival of every life became a social entitlement & human right, regardless of whether one wants to survive or expire..

What are the 7 requirements of life?

The seven characteristics of life include:responsiveness to the environment;growth and change;ability to reproduce;have a metabolism and breathe;maintain homeostasis;being made of cells; and.passing traits onto offspring.

What is the smallest unit of life?

cellThe cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.

Can life be created?

In May 2019, researchers, in a milestone effort, reported the creation of a new synthetic (possibly artificial) form of viable life, a variant of the bacteria Escherichia coli, by reducing the natural number of 64 codons in the bacterial genome to 59 codons instead, in order to encode 20 amino acids.
