Energy holds them together.
A mouse has a greater ratio of surface area rather than a hippopotamus.
Solution:
The function of a protein is determined by its shape.
The shape of a protein is determined by its primary structure (sequence of amino acids).
The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.
Neutron stars are created when
giant stars die in supernovas and
their cores collapse, with the
protons and electrons essentially
melting into each other to form
neutrons. Credit: NASA/Dana
