A different phenotype, head size, is perfectly positively correlated (1:1 relationship) with the ear size phenotype that you simulated for #9, but head size shows an opposing relationship with fitness, such that there is a negative relationship between head size and fitness. What do you expect to happen to the ear size phenotype from #9? Choose the correct answer below. a) selection increases ear size b) selection decreases ear size c) stabilizing selection on ear size

Your last submission is used for your score. 1. [0/2 Points] DETAILS PREVIOUS ANSWERS SCALCET9 3.4.001. MY NOTES ASK YOUR TEACHER PRACTICE A Write the composite function in the form $f(g(x))$. [Identify the inner function $u = g(x)$ and the outer function $y = f(u)$.] (Use non-identity functions for $f(u)$ and $g(x)$.) y = (6 - x$^8$)^5 $(f(u), g(x)) = (6 - x^8, x^5)$ Find the derivative $\frac{dy}{dx}$ $\frac{dy}{dx} = 5(6 - x^8)^4(-8x^7)$

The Sun provides the energy to drive the climate system and can also be harnessed using solar power technologies (a) If the radius of the Sun is approximately $7.0 \times 10^8$ m and has a surface temperature of 5800 K, determine the amount of energy emitted by the Sun per second. (b) Assuming that this energy is radiated uniformly from the Sun and that the separation between the Sun and the Earth is approximately $1.5 \times 10^{11}$ m derive the total power absorbed by the Earth. Note that the irradiance should work out to be approximately 1370 W.m$^{-2}$. You may ignore reflection in this calculation. The radius of the Earth is $6.4 \times 10^6$ m. (c) Derive a simple energy balance model that can be used to calculate the equilibrium temperature of the Earth given the incoming solar radiation. This model should use the fact that the Earth's albedo is roughly 0.3. You may also assume that the Earth's atmosphere does not impact the propagation of the incoming shortwave or outgoing longwave radiation in this very simple model. A diagram would be useful.

NG25230 Engineering Mechanics 2 6. The stresses on horizontal and vertical planes at a point on the outside surface of a solid circular shaft subjected to an axial load P and a torque T are shown in the Figure below. The normal stress on plane AA at this point is 55 MPa (T). Determine: a. The magnitude of the shearing stresses $\tau_h$ and $\tau_v$. (Ans: $\tau_h = \tau_v = 36.7$ MPa) b. The magnitude and direction of the shearing stress on the inclined plane AA. (Ans. $\tau_{nt} = 36.7$ MPa (CCW)) c. The principal stresses and the angle at which they can be found ($\sigma_{p1} = 73.4$ MPa (T) @ $\theta_{p1} = 26.6^\circ$, $\sigma_{p2} = 18.4$ MPa (C) @ $\theta_{p2} = 63.4^\circ$). d. The maximum shear stress ($\tau_{max} = 45.9$ MPa (CCW))

In the village of Frankfurter, the demand function for sausages per person is D(p) = 20 - 1.5p, where p is the price of a single sausage. The present population of Frankfurter is 100 persons. Suppose that 10 more people move into the town, each of whom has the same demand function as the old residents. At a price of $2, the price elasticity of demand for sausages in Frankfurter is (a) increased by 10% (b) decreased by 10% (c) unchanged (d) increased by 15% (e) None of the above. 5. Corrected_text: Consider a group of people A, B, C and the relation "At least as tall as and strictly heavier than." Is this relation transitive? Is it reflexive? Is it complete? (a) Yes; No; Yes (b) No; Yes; Yes (c) Yes; Yes; No (d) No; No; Yes (e) Yes; No; No (f) None of the above. 6. Corrected_text: If a firm is producing where MP/w < MP2/w2, the firm can reduce costs but maintain the same output by increasing the use of factor 1 and decreasing the use of factor 2.
