A space ship returns to Earth from a planet that has life forms. Although the astronauts are no longer on board, NASA funds strange neurons with the following unusual internal and external ion concentrations: Na$^+$ Internal (Cytoplasm) External (interstitial) 60 mM 6 mM K$^+$ 0 mM (zero) 0 mM (zero) Mg$^{2+}$ 0.0001 mM 1 mM Cl$^-$ 150 mM 15 mM Suppose these ions could move freely across the membrane through ion selective channels. Indicate the direction each type of ion would flow at room temperature if the membrane potential were fixed (held stable). Tip think about which direction the ion would flow, if you draw it up for yourself. You can draw a cartoon for yourself showing the ion concentration inside and outside the cell for this and each of the following questions and consider the direction of flow at room temperature. Mg$^{2+}$ flow at +90 mV: influx of ion into cell neither in nor out efflux of ion out of the cell

Skylar repairs microwaves. Her revenue, in dollars, can be modeled by the equation $ y=80+30 x $, where $ x $ is the number of hours spent repairing microwaves. Her overhead cost, in dollars, can be modeled by the equation $ y=10 x^{2}-20 $, where $ x $ is the number of hours spent repairing microwaves. After how many hours does she break even? Note: The phrase break even refers to the value where the two functions are equivalent. Enter your answer in the box. $ \square $
