Nonmetal atom
The structural units are the heart,blood, and blood vessels
Network solids are composed of an extended three-dimensional network of atoms bonded together by covalent bonds. Examples include diamond and quartz. The structural units in network solids are individual atoms or small groups of atoms connected to each other in a repeating pattern throughout the solid.
Nonmetal atom
In network solids, the basic structural units are atoms or ions held together by covalent bonds to form a three-dimensional network structure. These units are interconnected through strong chemical bonds in all directions, creating a continuous lattice structure. Examples of network solids include diamond (carbon atoms) and quartz (silicon and oxygen atoms).
ions
Amino acids are the basic structural building units of proteins.
Nucleotides are molecules that, when joined together, make up the structural units of RNA and DNA.
Nonmetal atom
Do you mean "nucleotide"? Nucleotides are molecules that, when joined together, make up the structural units of RNA and DNA.
