Beings from different planets in various galaxies often come to make new homes on the planet Lemuria and are then called Limurians. In fact, everyone on Lemuria previously came from somewhere else. Every now and then Limurians travel back to their original home planet at the rate of limspeed, which is 5000 limmetres per limminute, for a visit. Design, implement and test a Python class, Limurian, to generate objects which represent Limurians on planet Lemuria, with the following attributes/instance variables and class variables: Class variables: - Population, which is initialized to 1500 , is a class variable that keeps track of the total population of the planet Lemuria over time. As new objects are created (i.e., new Limurians come to the planet), the population number is automatically incremented by 1 . Hence, when the first object is created, the population should be changed to 1501 , when the second object is created, the population should be changed to 1502 , etc. - Lim_ID_Generator, which is initalized to 3000, is a class variable that is used to generate the 1 imID (see below) for a new object by increasing the previous ID (3000) by 2 and appending the first three characters of the name of the Limurian. For example, if the name of the Limurian is Shrilim, then the id for Shrilim should be 3002Shr. When the next object is created with the name Bhavlim, its ID would be 3004Bha. Etc. - LIMSPEED, which is set to 5000 , is the number of limmetres per limminute that Limurians travel when going back to their original planet. Instance variables: - 1 imID is 2 more than the value of the class varaible Lim_ID_Generator, with the first three characters of the Limurian's name appended, as described above - limName is the name of the Limurian - distanceFromOrig is the distance from planet Lemuria to the Limurian's original home planet, in limmetres Also include the following methods: - constructor method for the Limurian class - accessor method getLimID to retrieve the ID of the Limurian - accessor method getDistance to retrieve the distance of the Limurian's home planet from the planet Lemuria - mutator method updateDistance to change the distance from Lemuria to the Limurian's original planet - method computeTravelTime to compute the amount of travel time, in limminutes, that it takes a Limuria to travel to and from the Limuria's original home planet - special___tr__method to return the information about the Limurian, including the 1imID,1imName, distanceFromOrig and the time taken to travel to and from their original planet, with appropriate descriptive labels, as shown in the sample output Also include a main function to test the defined class as follows: - create 3 Limurian objects - print information about each Limurian using the __str_ method - update the distanceZromorig of the second Limurian and print the Limurian's ID, the old distance, and the updated distance with appropriate descriptive labels, as shown in the sample output - print th.

Austin Taylor and Edward Adelberg isolated some new strains of Hfr cells that they then used to map several genes in Escherichia coli by using interrupted conjugation. In one experiment, the researchers mixed cells of Hfr strain AB312, which were xl+mtl+mal+met+and sensitive to phage T6, with F strain AB531, which was xyl mt mal met and resistant to phage T6. The cells were allowed to undergo conjugation. At regular intervals, the researchers removed a sample of cells and interrupted conjugation by killing the Hfr cells with phage T6. The F cells, which were resistant to phage T6, survived and were then tested for the presence of genes transferred from the Hfr strain. The results of this experiment are shown in the graph. On the basis of these data, give the order of the xyl,mtl,mal, and mer genes on the bacterial chromosome and the minimum distances between them in minutes. The origin of transfer is represented by the red triangle. The distances between genes art not to scale. The circle represents the bacterial chromosome and the lines through the circle are gene locations..

b. JAJ Enterprises has generated an increasing amount of net income, but a decreasing amount of cash from operations (CFO) from 2014 to 2015. In 2014, decreases in inventories and other current assets and increasing accounts payables caused CFO to be higher than net income, despite increasing accounts receivables. In 2015, accounts receivables increased significantly along with increases in inventories and other current assets, while accounts payables were decreasing. These changes all caused CFO to be much lower than net income. This pattern is generally seen in companies unable to manage their working capital well, or in firms that are new or expanding. The net income increasing is a positive sign that may signal expansion..

Astronomy. 1511 Laboratory Manual In studying the physics and chemistry of our solar system, we learn more about its origins and how it will evolve in time. In light of the discoveries of extra solar planets and the stars they orbit around, we can use information we learn about them to understand more about our own planets to reach a deeper understanding. Calculating the Mass of the Moon Mass is the dominant factor in the initial formation of a solar system, so we: carefully study the masses of objects to understand how it has an affect during formation and after the system is stable over a period of time. When you learned about Kepler's Three Laws of Planetary Motion and Newton's Law of Gravity, you were provided the tools to understand the relationships between the orbital properties of the planets and the Sun. Because these physical laws are universal, they also apply to all orbiting objects. As long as the objects are allowed to move in a natural way, Kepler's Third Law enables us to calculate the mass of the source of gravity for the orbit. You are going to use a portion of the ephemeris (position and time) data collected by the Explorer 35 spacecraft when it orbited the Moon to draw its orbit. From this drawing you will use the properties of the ellipse (refer to your lab on Kepler's Laws and your textbook for assistance) to determine its semi-major axis. With data from Table 1 and the semi- major axis measurement, you will use the equation for Kepler's Third Law to calculate the mass of the Moon. Activity: 1. Plot the data from Table 1 on the graph. Please note that only the position data is used for the graph. 2. Use a ruler to find the major and minor axis of the ellipse. This requires you to use your best judgment to determine where they are located. Recall that the longest distance in the ellipse is the major axis and the shortest distance is the minor axis. Lay the ruler across the graph and rotate it around until you find them, then draw each line. The intersection of the two lines should be the geometric center of the ellipse. 3. The center of the Moon is located on the graph at the coordinates (0,0) in lunar radii. Since the Explorer 35 spacecraft orbited around the Moon, according to Kepler's 1 ut Law, the Moon must be at one focus of the ellipse. 4. Note that the scale of the grid on the graph is approximately: 1 Lunar Radii =10 small grid boxes a 23.7mm. Astronomy 1511 Laboratery Manua! Table 1 - Explorer 35 Ephemeris Data 5. Find and record the following properties of the ellipse in terms of Lunar Radii: (These properties require either measurement and calculation or just calculation. You will need your calculator to convert from millimeters to Lunar Radii.) a. The Semi-Major Axis (a): b. The Semi- Minor Axis (b): c. Measure the distance from the intersection of the lines for the major and minor axis to the center of the Moon at (0,0). This distance is labeled, c. The Distance from the Center of the Ellipse to the Focus (c).
