Describe the results observed for pairing (d). Note how these results differ from those for pairing (b). Suggest a hypothesis to explain this difference. How could you test your hypothesis using the kinds of mice in this study?

First, practice reading the genotype information given in the data table. For example, pairing

(a) joined two mice that each had the wild-type version of both genes. Describe the two mice in pairing

(b), pairing

(c), and pairing

(d). Explain how each pairing contributed to the experimental design.

a. Suppose that $F(x,y)=0$ defines $y$ implicitly as a function of $x$ and $F$ is differentiable. Write an expression for $\frac{dy}{dx}$. Illustrate with a tree diagram.

b. Suppose that $F(x,y,z)=0$ defines $z$ implicitly as a function of $x$ and $y$ and $F$ is differentiable. Write an expression for $\frac{\partial z}{\partial x}$. Illustrate with a tree diagram.

Given the following equations, evaluate dy/dx. Assume that each equation implicitly defines y as a differentiable function of x. $\sqrt { x ^ { 2 } + 2 x y + y ^ { 4 } }$=3

An insulinoma is a cancerous mass of pancreatic beta cells that secrete insulin but do not respond to feedback mechanisms. How you would expect an insulinoma to affect blood glucose levels and liver activity?

Formic acid, HCOOH, is a weak electrolyte. What solutes are present in an aqueous solution of this compound? Write the chemical equation for the ionization of HCOOH.

Write the formulas of the conjugate bases of the following acids:
$\mathrm{HCOOH}$ (formic acid)..

A sample of ${N}_2 {O}_4$ gas with a pressure of 1.00 atm is placed in a flask. When equilibrium is achieved, 20.0% of the ${N}_2 {O}_4$ has been converted to ${NO}_2$ gas.

(a) Calculate $K_{{p}}$.

(b) When the original pressure of ${N}_2 {O}_4$ is 0.10 atm, what is the percent dissociation of the gas? Is the result in agreement with Le Chatelier's principle?

An aqueous solution contains a mixture of $0.0500\ \mathrm { M }\ \mathrm { HCOOH } \left( K _ { \mathrm { a } } = 1.77 \times 10 ^ { - 4 } \right)$ and $0.150\ \mathrm { M }\ \mathrm { CH } _ { 3 } \mathrm { CH } _ { 2 } \mathrm { COOH } \left( K _ { \mathrm { a } } = 1.34 \times 10 ^ { - 5 } \right).$ Calculate the pH of this solution.

Solve the following.

A solution of formic acid $\left(\mathrm{HCOOH}, K_{\mathrm{a}}=1.8 \times 10^{-4}\right)$ has a pH of 2.70 . Calculate the initial concentration of formic acid in this solution.
