The electrostatic forces of attraction between the shared pair of bonded electrons and the positively charged nuclei hold the atoms together.

Substitute y = 5x + 2 into 8x + 7y = 11 to get, 8x + 7(5x + 2) = 11This simplifies down to 8x + 35x + 14 = 11And further simplifies to 43x = -3 giving the solution x = -3/43Substituting the x solution bac...

Phagocytosis is a non-specific cellular defence mechanism by the body which is initiated when a pathogen invades the body and has antigens which are detected as antigenic or foreign – note that antigens a...
