What is homeostasis?

a.

production of urine.

b.

maintaining a stable internal environment.

c.

excretion of waste materials.

d.

none of the above.

B Homeo - i think means internal because of the prefix home and stasis usually means that whatever it its, is being preserved and or maintained.

Homeostasis refers to the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with external changes.

So, I would say:

D) None of the above.
