Answer: In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. ... This enables better survival and reproduction compared with other members of the species, leading to evolution.Adaptations are the result of evolution. ... Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation.

This creates one atom with a negative charge, called an anion, and one atom with a positive charge, called a cation. The attraction between these charges hold the atoms together in an ionic bond.
Hydrogen bonds are inter-molecular bonds. The key difference between hydrogen bond and ionic bond is that ionic bonding exists between permanent anions and cations, whereas hydrogen bonds exist between partial positive and partial negative charges
