Answer 1

Answer:

The correct answer is B. Ingesting too much alcohol leads to vomiting.

Explanation:

Homeostasis is the ability of the body to resist the chemical or physical change in the body and remain in constant and steady-state for example in hot days when temperature goes above 40° Celcius our body temperature remains at 37° c with the help of sweating.

Another example is vomiting after ingesting too much alcohol because alcohol is toxic and ingesting too much alcohol produces extra acids in the stomach which irritates stomach lining that results in upset stomach and vomiting.  

So by vomiting the alcohol our body reduces the toxic effect of alcohol in the body and resist the change in the body.
