Suppose a plant has two different alleles for flower colour, one red (R) and one white (r). In a population of ten plants, the frequency of R and r is 0.5 each. However, only six of these plants produce viable offspring by chance, resulting in a shift in the frequencies of R (0.8) and r (0.2) in the next generation. Identify the cause of such a shift.

As shown in the figure below, you have a system including a Cadmium cup with mass $M_{cup} = 0.303$ kg. The cup contains water with mass $M_{water} = 0.442$ kg., Both the cup and water are initially at a temperature of 45.0 degrees Celsius. You drop ice into the system. The ice has an initial temperature of -53.4 degrees Celsius and a mass of $M_{ice} = 2.936$ kg. The system will reach equilibrium with none the ice having melted and all of the water having frozen onto the ice block at some final temperature below 0 degrees Celsius. \text{ice} \text{ice} \text{ice} \text{water} \begin{itemize} \item None of the ice melts. \item All of the water freezes onto the ice. \item The system reaches equilibrium at $T < 0^\circ C$ \end{itemize} \text{cup} Find the system's final temperature, $T_{final} = $ degrees Celsius \begin{tabular}{|l|c|} \hline Material & $c$ (J/(kg K)) \\ \hline Aluminum & 897 \\ Beryllium & 1820 \\ Cadmium & 231 \\ Iron & 412 \\ Lead & 129 \\ Polyethylene & 2303 \\ Steel & 466 \\ Uranium & 116 \\ \hline \end{tabular} \begin{tabular}{|l|c|} \hline Water $c$ (J/(kg K)) & Water $L$ (J/kg) \\ \hline ice & 2090 \\ water & 4186 \\ steam & 2010 \\ \hline \end{tabular} \begin{tabular}{|l|c|} \hline & \\ \hline Fusion & 334000 \\ Vaporization & 2230000 \\ \hline \end{tabular}

1.) In an effort to increase productivity on a factory floor a company is upgrading it's ventilation fan system to provide more fresh air to it's 160 skilled laborers. Following ASHRAE standards a minimum of 1800 L/min per person is set as the target volume flow rate of air. The building has a large open floor plan 90 meters by 140 meters with a 7 meter high-bay ceiling. To keep noise down and avoid requiring hearing protection for the workers flow velocities should not exceed 10 m/s. Determine a.) the total mass flow rate (kg/s) and b.) the minimum diameter (cm) required of the ventilation fan. Also, determine c.) what this flow rate amounts to in air changes per hour (ACH) for the building (i.c., how many times the entire volume is evacuated per hour). Assume $\rho_{air} = 1.225$ kg/m².
