In the text "Human Growth and Development Across the Lifespan", What questions would you ask Juanita to learn more about how the attachment between Marcus and his foster parents (Juanita and Roberto) are being interrupted? What are the long-term implications of this type of attachment scenario?

During oxidative phosphorylation, why does a single molecule of NADH result in the production of more ATP molecules than a single molecule of FADH$_2$? Choose one: O FADH$_2$ promotes the pumping of more protons than does NADH. O FADH$_2$ has a lower electron affinity than does NADH. O NADH donates more electrons to the electron-transport chain than does FADH$_2$. O FADH$_2$ and NADH feed their electrons to different carriers in the electron-transport chain. O FADH$_2$ is less likely than NADH to participate in the electron-transport chain.

b. Given: As we did in Block I, you will develop a system of equations to help solve for unknown currents and voltages. In this block, the unknown variables will be complex numbers. Therefore, you need to be able to solve a system of equations where the unknowns are complex. You have the following equations. Note $V_1$ and $V_2$ represent complex numbers. You are welcome and encouraged to use Matlab to help you solve these equations. $\frac{V_1 - V_2}{j1,800} + \frac{V_1}{800} + \frac{V_1 - 12\angle60^\circ}{600} = 0$ $\frac{V_2 - V_1}{j1,800} + \frac{V_2}{-j500} = 0$ Find: The complex values for $V_1$ and $V_2$. You may leave your answers in either polar or rectangular form. Solution:

5. Particle setting in a batch reactor Consider an unstirred batch reactor. The reactor is in the shape of a right circular cylinder with a vertical axis. The volume is V = 30 L and the height is H = 70 cm. The reactor is filled with water. Suspended in the water are particles of two sizes. The initial condition (at time t = 0) has all of the particles of each size uniformly suspended throughout the reactor. For t > 0, the particles settle to the bottom of the reactor with their respective settling velocities. The data in the following table define the particles in the system. Symbol Parameter Particle size 1 Particle size 2 dp Particle diameter 5 ?m 10 ?m mp Initial suspended 50 mg 150 mg mass Vs Settling veocity 7.4 cm/h 29 cm/h a. The total mass of particles suspended in the water is initially 200 mg. Plot the mass of particles that remain suspended, m, as a function of time for 0 < t < 8 h. b. Compute the particle mass flux (mass per area per time-- remember the sign indicates the direction of the flux) that is attributable to settling to the bottom of the reactor versus time. Show your results as a plot of J, versus t for 0 < t < 8 h.
