what are the independent, dependent and controlled varible in this experiement.
my paper says this:
Indivdual organisms must maintain a relitvely stable internal enviroments. both organisms and cell respond to many evironmental factors that otherwise would change their internal enviroment.
How do organisms maintain the pH of their tissues within a normal range despite activities that tend to change the pH? You begin to answer the question by comparing that response of a nonbiological material and a biological material to the addition of acid and a base. The nonbiological material is tap water and the biological material is one of severl species devrived from organisms.What are the contolled, independent, and dependent variables?
independent: pH environment
dependent:response of the material to the pH change
controlled: tap water, species usedWhat are the contolled, independent, and dependent variables?
when controlled,how can you have independence.you would only have dependence....right?
