Figure 1. The phylogeny of the milkweed butterflies (left), the amino acid changes in the cardenolide binding pocket of the Na-K pump (middle: V: valine; L: leucine; H: histidine; N: asparagine), and the relationship between cardenolide concentration and Na-K pump activity in the susceptible (blue), partially resistant (orange), and fully resistant (red) species (right). Of the following options, choose the one that is the best explanation for your observations. Reject all the rest. For full points you must also provide an explanation for each case. Defend the correct choice with adequate justification. For those that are false, explain why they are incorrect. Accept/Reject: The common ancestor of the Monarch and the Disturbed Tigerwing was partially resistant to cardenolides due to a mutation in amino acid position 2 of the Na-K pump, switching leucine to valine. A second mutation arose in the common ancestor of the Common Tiger and the Monarch that switched asparagine in position to 5 of the Na-K pump to histidine, making the butterfly almost completely resistant to cardenolides. Accept/Reject: The common ancestor of the Southern Monarch and the Blue Tiger was partially resistant to cardenolides due to a mutation in amino acid position 2 of the Na-K pump, switching leucine to valine. The common ancestor of the Southern Monarch and the Monarch was almost completely resistant to cardenolides due to a second mutation in amino acid position 5 of the Na-K pump, switching asparagine to histidine. Accept/Reject: In the common ancestor of the Blue Monarch and the Monarch butterflies, a single mutation in the cardenolide binding pocket of the Na-K pump occurred in response to the cardenolides in the butterfly's diet of milkweed. In the common ancestor of the Monarch and Southern Monarch butterflies, a second mutation occurred due to the butterfly's milkweed diet, which made the Na-K pump almost completely resistant to cardenolides. Accept/Reject: The common ancestor of the Blue Monarch and Common Tiger butterflies was not resistant to cardenolides. However, random mutations, first in the Blue Monarch butterfly and then in the Common Tiger butterfly, made their Na-K pumps partially resistant to cardenolides and ensured that both species were able to live and feed on milkweeds. This mutation then spread through the populations because it gave the butterflies a fitness advantage. Accept/Reject: Monarch and Southern Monarch butterflies are more highly evolved than the other milkweed butterflies because they are almost completely resistant to cardenolides produced by the milkweed. The Disturbed Tigerwing butterfly is the least highly evolved because it is not resistant to cardenolides at all.

Steam at 3 MPa and 350Â°C is supplied to the turbine of a power plant as shown in Figure Q1 at the flow rate of 10 kg/s operating on Rankine Cycle. The turbine expands the steam to 75 kPa, and the steam is condensed at the condenser. The specific heat of water is 4.17 kJ/kgK. Property values can be found in the Appendix QA1. (a) Plot the T-s diagram of the cycle. (5 marks) (b) Determine the turbine power output per unit mass of steam. (10 marks) (c) Determine the flow rate of cooling water to remove the heat from the condenser. (5 marks) (d) Determine the thermal efficiency of the cycle if the power consumption of the pump is not neglected, and compare the efficiency of the cycle with that of a Carnot cycle operating within the same temperature limits in the wet region.
