Which has the most control of traits and inheritance?

nucleic acids

Explanation:

Nucleic acids are macromolecules made up of nucleotides and which form two important components of cells, DNA and RNA. They have the greatest control of traits and inheritance because they are the ones that keep all genetic and hereditary information.

They receive this name because they have an acid character and are found in the nucleus of the cell.

Nucleic acids are essential for all cells, since it is from DNA and RNA molecules that proteins are synthesized, cells multiply and the mechanism of transmission of hereditary characteristics still occurs.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
