A group of individuals of the same species that interact will find a mate and cross breed and produce a stronger species to survive they're environment. per Darwin's law..
No it’s not alive it just has adhesion as a property. It doesn’t have cells that make it living, and it doesn’t make or eat food to survive. And the force from the waves make it roll up on the beach, not because it’s alive.
2)
it’s charge would increase by -1
Explanation:
The type of atoms is usually determined by the number of protons. Different isotopes of an atom differ in the number of neutrons only. The number of electrons, however, in neutral atoms is the same as that of the protons. Its charge is zero because the positive charge of the protons cancels out with the negative of the electrons. Adding an electron to a neutral atom, therefore, increases the negative charge of the atom by 1
