Both the area pellucida epiblast and the area opaca epiblast play roles during chick gastrulation. Which of the following best describes their involvement in this process? a) The area pellucida epiblast contributes cells that move through the primitive streak to form the mesoderm and endoderm, while the area opaca epiblast remains static and does not participate in gastrulation. b) The area pellucida epiblast forms the hypoblast, while the area opaca epiblast generates the primitive streak and drives gastrulation. c) The area pellucida epiblast gives rise to most of the embryonic tissues through cell movements at the primitive streak, while the area opaca epiblast contributes some endoderm and (through the hypoblast) extraembryonic structures such as the yolk sac. d) The area pellucida epiblast and the area opaca epiblast both contribute cells to the primitive streak, which completely forms before cell movements result in separation of the mesoderm and endoderm layers from the epiblast.

EXERCISE SET 3.1 1. Verify that the function f(x) = x^2 sin x + 2x - 3 has exactly one root in (0, 2). Find this root by using the bisection method with an error of no more than 10^-5. Count the number of iterations needed to find the root and compare your answer with the result obtained by using the error formula given by Theorem 1 of Section 3.1. EXERCISE SET 3.2 1. Verify that the function f(x) = x^2 sin x + 2x - 3 has exactly one root in (0, 2). Find this root using the method of false position with an error of no more than 10^-3. EXERCISE SET 3.4 1. Approximate to within 10^-6 the root of the equation e^-2x - 7x = 0 in [1/9, 2/3] by the secant method. EXERCISE SET 3.5 1. Find the roots of the following equations correct to six decimal places using Newton’s method. (a) x^5 - 3x^3 - x + 4 = 0, x0 = 0, (b) 3x^3 - x + 4 = 0, x0 = -1, (c) x^3 - x^2 + ex = 0, x0 = -1, (d) ex + x sin x = 0, x0 = 0. EXERCISE SET 3.8 1. Solve the nonlinear system of equations ln(x^2 + y) - 1 + y = 0 √x + xy = 0 using Newton’s method with x0 = 2.4 and y0 = -0.6.
