Find the statement that is NOT true. First exclude the four statements that accurately describe how various living organisms keep their membranes at an appropriate fluidity. Plants alter the fatty acid composition of their membrane phospholipids in response to seasonal temperature changes Humans adjust the fatty acid composition of their membrane phospholipids to maintain the proper level of fluidity as temperatures change seasonally. Mammals invest energy to regulate body temperature Bacteria adjust the fatty acid composition of their membrane phospholipids to keep their membranes fluid in the winter Cholesterol buffers membrane fluidity of mammals

This exercise shows how trade leads to gains by all trading partners through specialization and comparative advantage. Suppose that Japan has 20 laborers in total and that the United States has 40 laborers. Suppose their production possibilities are given in Table 35.2. (Be careful: The table tells you that'a worker in Japan can produce 2 TV sets per day or 10 bicycles per day, not two TV sets and 10 bicycles!) - Table 35.2 Output per worker day in the United States and Japan Country TV sets Bicycles (per day) (per day) Japan 2 10 United States 1 8 1. Draw the production possibilities curves for each country in Figure 35.1. Assume constant costs of production. Japan United States

use MATLAB to generate an appropriate plot of the pmf of Y found in (a). | A modem transmits a +2 voltage signal into a channel. The channel adds to this signal a noise term that is drawn from the set \{0, -1, -2, -3\} with respective probabilities \{4/10, 3/10, 2/10, 1/10\}. (a) Find the pmf of the output Y of the channel.

Problem 7: (14 points) Synchronization strategy of taxis and customers at the airport. Taxis arrive at the airport in order. If there are customers waiting, a taxi driver immediately picks up the one waiting customer who arrived the earliest. Otherwise, the driver waits in a taxi-queue. Similarly, an arriving customer checks if there are taxis waiting. If so, she gets into the taxi that arrived the earliest. Otherwise she waits in line. Each taxi only picks up one customer. Each driver and customer will be a separate thread executing functions taxi() and customer() respectively. Function taxi() calls done() when a customer is picked up, while customer() calls done() when a taxi has been boarded. You are requested to write code for the above two functions. Assume that the number of drivers (say N) is infinitely recycled and that new customers keep arriving. Hence, you may assume that the variable associated with the taxi drivers is circular or you may assume that the counter associated with the customers is also circular. lock c_lock, d_lock; // protect the shared variables of customer and driver int driver_ticket = customer_ticket = -1; Part 1: (4 pts) How will you implement the above problem: with condition variables, with semaphores, or you may use any of the above? Please FULLY justify your selection. Part 2: (10 pts) Write code or pseudo-code using the synchronization primitive(s) selected above.
