Higher level of organization are built from lower levels. Therefore, molecules combine to form cells, cells combine to form tissues, tissues combine to form organs, organs combine to form organ systems, and organ systems combine to form organisms.
The levels of organization from simple to complex

Bases have a pH level below 7 is falseFurther explanation
pH is the degree of acidity of a solution that depends on the concentration of H ions. The greater the value the more acidic the solution and the smaller the pH.pH = - log [H⁺]
The pH range is: 0-14acidic if the pH is <7 neutral if pH = 7 base if pH> 7
A base is a substance when dissolved in water, can produce OH⁻ ions.
Usually the nature of the base or acid can be known one of them with indicators, such as litmus.
Then the pH of the base is in the range between 8-14, and acidic between 0-7Learn more
