Which macromolecules provide instructions for growth

Nucleic acids.

Explanation:

Nucleic acids are macromolecules made up of nucleotides that form two important cell components, DNA and RNA. They are called this because they are acidic and found in the nucleus of the cell. Nucleic acids are essential for all cells, because it is from the DNA and RNA molecules that proteins are synthesized, the cells multiply and the mechanism of transmission of hereditary characteristics still occurs. They are also the macromolecules responsible for the instructions for growth.

In addition, nucleotides are important in several processes, such as the synthesis of some carbohydrates and lipids and the regulation of intermediate metabolism, activating or inhibiting enzymes.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
