Researchers studied the replication behavior of a certain virus. From an initial 1,000 copies of the virus, the researchers found that the virus population was increasing at a rate of 14% every 4 hours. The number of viruses N is given by the following model, where t is the number of hours after the study began with the 1,000 copies of the virus. $$N = 1,000(1.14)^{t/4}$$ Use the model to predict the number of viruses in 17 hours. Round to the nearest whole number. X viruses SUBMIT ANSWER

AFB cultures must be incubated for several weeks before a specific diagnosis of Mycobacterium tuberculosis can be made. In contrast, routine cultures require only 48 hours for identification . Which of the following explain why this is so: A. the presence of teichoic acids in the cell wall promotes slow acquisition of nutrients due to a hydrophilic cell wall . the presence of N-acetyl muramic acid (NAM) in the cell wall promotes slow acquisition of nutrients due to a hydrophobic cell wall the presence of mycolic acids in the cell wall promotes slow acquisition of nutrients due to a hydrophobic cell wall D. the presence of lipid A in the cell wall promotes slow acquisition of nutrients due to a hydrophilic cell wall E. the presence of large amounts of peptidoglycan that protects the cell from osmotic lysis F. the presence of an endospore that is not biologically active until two weeks after culture due to the hydrophobic nature of the endospore G. none of the above apply

Q4. Consider the following program, and judge whether the three integer side lengths can form a triangle. This triangle can be general triangle, an isosceles triangle or an equilateral triangle, and finally outputs the triangle type. [Note: The sum of the two sides is greater than the third side, and the absolute value of the difference between any two sides is less than the third side. It can form a triangle] (6 Marks) a. Draw the CFG of the program and calculate the full complexity. b. Write the basic paths covered. c. Design a set of 4 test cases to meet the basic test path coverage criteria. Following is the set of input data:
