• any use of antibiotics will select for resistant bacteria
• overuse of antibiotics in livestock
Answer:
im pretty sure it's the second option .-.
Organisms depend on buffer that are compounds that stabilize pH by absorbing or releasing h ions. It consists of weak acids and weak bases.
The buffer is also consists of undissociated acid (HA) and the ions that are made by dissociating the acid (A-). Because of the presence of weak acids and bases and to stabilize the pH the buffer absorb or give off H+.
The nucleic acids must have positive charge that helps in formation of double helices.
Undissociated acid means when an acid dissociates to release a proton to make the solution acidic.
