You are studying a prickly pear cactus population. There are two alleles for spine length, L is dominant for long spines, and l is recessive for short spines. If the phenotypic frequency of short spines in the population is 0.1598, what is the allele frequency for the dominant allele (L)? In other words, what is p? Round your answer to the fourth decimal after each step. Group of answer choices p2 2pq q2 (observed-expected)2 p+q

Carbon dioxide undergoes reversible expansion from 1x10-3 m3 to 5x10-3 m3 at 350 K following the van der Waals equation of state (with a = 0.36 J·m3/mole^2 and b = 4.3 x10-5 m3/mole). Compare the entropy change to an ideal gas undergoing the same expansion. Explore whether the entropy change remains the same if the van der Waals gas expansion is irreversible. Calculate the entropy change, ΔS, for the thermostat and the van der Waals gas as an isolated system. Investigate whether the entropy change for the thermostat is unchanged if the gas expansion is irreversible. Analyze if the chemical potential of the gas in the final state differs from that in the initial state. Compare the change in chemical potential, Δμ, for the van der Waals gas to that of an ideal gas under the same conditions.

Please help and write clearly, showing all work. Suppose that a firm produces cars, and they exist in an oligopoly. Specifically, there are two firms in the market which produce cars that are basically identical. They are so close that they both share the same market demand. Suppose that market demand is given by: p = 200 - 0.5QD. And assume (for simplicity) that both firms have a constant marginal cost of $10, with zero fixed costs. Each firm has to decide between two prices they could set, which are either (i) $105 or (ii) $60. If both firms choose the same price, then they split the market (i.e. they each produce half of the market demand and earn the revenue for those units). If the two firms choose different prices, then the firm with the lowest price takes all of the market demand at that price, and the firm with the highest price produces nothing (i.e. Q = 0). Which outcomes, if any, are Nash Equilibria? How do you know?

We are distilling a mixture with dumped packings shown in Table 10-3. The column operates at atm pressure. The flow rate of a liquid feed containing fm-mole-% methanol to the column is F Ib-moles/hr. The feed stream is fed to the packed column at Tf C. The column has a total condenser and a partial reboiler. The external reflux ratio is R. The distillate product contains dw mass fraction methanol, whereas the bottom product contains bf mole fraction methanol. A safety factor for the cross-sectional area of a packed column is 1.32. Data necessary for this problem are available in Tables 2-7 and 10-3, and the formulas for physical properties are shown below. The vapor phase is assumed to be ideal gases. The liquid phase is assumed to be ideal solutions.

Find the pressure drop in inch water per ft-column height. Find the top operating line equation. Determine the temperature of the bottom product in C. Find the condenser duty (Q) in kcal/hr, using Watson's method (equation). The critical temperatures of methanol and water are 512.6K and 647.3K, respectively.
