(b) The ODE in (a) is of the form $x' = f(x,h)$. Plot $x'$ vs $x$ for $h = 0$, clearly labeling all roots and the absolute maximum of the graph. Plot the phaseline, and state all equilibria and their stability. Assuming the initial population is nonzero, does the population ever become extinct? (c) Using graph graph in (b), plot $x'$ vs $x$ for $h < 1/4$. Plot the phaseline, and state all equilibria and their stability. Assuming the initial population is nonzero, does the population ever become extinct? (d) Using graph graph in (b), plot $x'$ vs $x$ for $h > 1/4$. Plot the phaseline, and state all equilibria and their stability. Assuming the initial population is nonzero, does the population ever become extinct? (e) If the fish population in a lake has a growth rate of 0.2 per month, with a carrying capacity of 40 thousand, and is initially populated at its carrying capacity, how many fish can be harvested per day at most to assure that the population will not become extinct? What assumption did you make?

3. Distilled water is a poor conductor of electricity, but if you add a small amount of sodium chloride (NaCl), you can get a current to pass through. Would salt water become more conductive as you get closer to the saturation point? (AKS 6a/ DOK 3) A. No, it would not become more conductive because the concentration level does not affect conductivity. B. Yes, it would become more conductive because the increased concentration level would indicate an increase in the number of ions in the solution once the salt has dissolved. C. No, it would not become more conductive because the increased concentration level would indicate that there are too many ions in the solution once the salt has dissolved. D. Yes, it would become more conductive because the decreased concentration level would indicate an increase in the number of ions in the solution once the salt has dissolved. 4. If a solution is temporarily able to hold more solute than it originally could hold, what would we call that type of solution? (AKS 6a/ DOK 1) A. saturated B. supersaturated C diluted D. concentrated
