Identify the disease states resulting from: A. over-secretion B. under-secretion of vasopressin and list the principal symptoms associated with each condition. Over-secretion of vasopressin leads to syndrome of inappropriate antidiuretic hormone (SIADH), characterized by water retention, hyponatremia, and neurological symptoms such as confusion and seizures. Under-secretion causes diabetes insipidus, presenting with excessive urination (polyurial, extreme thirst (polydipsia), and dehydration. Over-secretion leads to diabetes mellitus, characterized by hyperglycemia, polyuria and increased thirst. Under-secretion results in syndrome of inappropriate antidiuretic hormone (SIADH), presenting with excessive water retention, dilutional hyponatremia, and neurological manifestations. Over-secretion results in nephrogenic diabetes insipidus, characterized by the kidneys' reduced response to vasopressin, leading to excessive urination and thirst. Under-secretion causes central diabetes insipidus, presenting with hypotension, tachycardia, and hypovolemia. Over-secretion causes SIADH, characterized by dilutional hyponatremia, water retention, and neurological symptoms. Under-secretion leads to diabetes insipidus, presenting with hypernatremia, polyuria, and polydipsia

(1) Set up the Riemann sums for the following functions over the given intervals. Then, after setting them up, compute the Riemann sum. (Feel free to use a computer or calculator to compute the Riemann sum after you set it up. You need to show your setup to get full points.) (a) $R_6$ for $f(x) = x^3 + 1$ from $x = 2$ to $x = 5$. (b) $L_4$ for $f(x) = x^2 + x$ from $x = -2$ to $x = 2$. (c) $L_8$ for $f(x) = \sin x$ from $x = 0$ to $x = 2\pi$ (2) Alice and Bob write some code to compute the right Riemann sum $R_n$ of the integral $\int_0^1 x^2 \, dx$ for any $n$. When Alice uses her code to compute $R_{1000000000}$, she gets 0.3333333338. When Bob runs his code to compute $R_{1000000000}$, he gets 4.000000001. Whose code is more likely to be correct? Why?
