Stels [109]

Answer:

A living being or organism is a complex set of organizational material, in which molecular communication systems intervene that relate it internally and with the environment in an exchange of matter and energy in an orderly manner, having the ability to perform the basic functions of life that are nutrition, relationship and reproduction, in such a way that living beings work by themselves without losing their structural level until their death.

Explanation:

The matter that composes living beings is formed in 95% by four elements (bioelements) that are carbon, hydrogen, oxygen and nitrogen, from which biomolecules are formed: 3 4

Organic biomolecules or immediate principles: carbohydrates, lipids, proteins and nucleic acids.

Inorganic biomolecules: water, mineral salts and gases.

These molecules are constantly repeated in all living beings, so the origin of life comes from a common ancestor, as it would be very unlikely that two living beings with the same organic molecules have independently appeared.5 6 Stromatolites have been found 3700 million years old, 7 so that life could have arisen on Earth 4100-3800 million years ago.1 8 9

All living things are made up of cells. Inside these are carried out the sequences of chemical reactions, catalyzed by enzymes, necessary for life.

The science that studies living things is biology.

Could there be a frameshift mutation that would not affect the
dusya [7]

Answer:

no, because it would have to be a perfect process, and changing would end in a mistake.

Explanation:

(detail) It would be unlikely, because a frameshift mutation shifts every nucleotide down one, so several amino acids in the protein are likely to be changed. However, if a frameshift mutation occurred near the end of the DNA sequence, the protein could have minimal changes to its structure and function.
