What is the function of the “control centre” in homeostasis?
Control centre is usually the brain. Control centre receives message and decides what needs to happen in order to return the condition to its normal state. It then sends a message to the effector

What is the function of the “effector” in homeostasis?
The body organ or part that will effect change or make the change happen.

give an example of a weak acid
Carbonic acid
Why is acid base balance important?
The body needs to maintain a balance of pH 7.35-7.45. Dropping blood pH can cause real issues in the body. If Blood PH drops from 7.35 to 7.26 it has issues with the brain function, nausea, breathing rate increase, drowsy
Explain how buffers work
A Buffer is a solution that resists changes in PH when small amounts of acid or base are added to it. It maintains its PH.
If any acid is added to the buffer, the base part of the buffer reacts with it , so removes it. If any base is added to the buffer the acid part of the buffer reacts with it so removes it. Any added acid (H+) will react with the base part of the buffer and be neutralised/Removed. Any added base (OH-) will react with the acid part of the buffer and be neutralised/ Removed.
