D is the answer to the very bottom
According to Webster Dictionary, Homeostasis is a relatively stable state of equilibrium or a tendency toward such a state between the different but interdependent elements or groups of elements of an organism, population, or group.
In simpler words, homeostasis is a period in time where things are relatively balanced and able to adapt to change without causing a lot of problems. I found a few examples involving the human body including body temperature, glucose levels and fluid volume. If you need an extra explanation, I will link the site if examples down below. (:
Happy studying!

This excerpt from section 3 of "An Occurrence at Owl Creek Bridge", contributes to the theme of fate because <em>It suggests that Farquhar is wrestling with forces larger than himself.</em> In the first section, Peyton Farquhar is on a railroad bridge twenty feet above the water. His wrists are tied on his back and in his neck, there is a noose. He is surrounded by soldiers of the Northern army. His execution is going to take place very soon. In section 2, the narrator introduces Farquhar using a flashback to tell us that he is a planter devoted to the Southern cause. In section 3, the narrator goes back to the present and Farquhar is falling from the bridge. He is feeling pain but everything looks strange for him, the stars above him, the language that he hears, and everything appear to have a malign significance.
