the conjugate acid/base of an acid-base pair
Acids donate protons to a solution, while bases accept protons. Acid-base reactions involve the transfer of protons between species in a solution.
The number of protons in an atom determines its identity as a specific element. Changing the number of protons would change the element. Neutrons and electrons can be added or removed without changing the identity of the element since they do not affect the element's chemical properties.
The identity of every element is given by the number of protons in the nucleus. To keep electrical neutrality, they also have the same number of electrons.See the Related Questions for more information about protons, neutrons, and electrons in atoms.
A chemical species that behaves both as an acid and as a base is called an "Amphoteric species".Examples :H2O acts as an acid as well as a base.
Electrons are so small they contribute nothing to atomic mass. So since atomic number of 9 is the number of protons and atoms are generally neural it needs 9 to cancel out the positive charges of the protons.
due to difference in mass of different type of species
Closely related species are species that share a recent common ancestor and have a high degree of genetic similarity. They often have similar physical traits, behaviors, and ecological roles, indicating a close evolutionary relationship.
In taxonomy, a specific epithet is the second part of a species name that describes a particular characteristic of the organism, while a species is a group of organisms that can interbreed and produce fertile offspring.
There are 358 species and varieties of mosses in Minnesota. See related links for information about where to find some of the difference species in the state.

They are common names for related and very similar species. Please see the related question below which explains more clearly.
Threatend Species
Protons are positively charged species found inside the nucleus. The number of protons decides what element it is and its position in the periodic table.
They are related to all other species of ant.
