In each question below is given a statement numbered I, II and III. An assumption is something supposed or taken for granted. You have to consider the following assumption and decide which of the assumption is implicit in the statement. Statement: The June 2018 quarter results of Infosys reflect that the investors waiting for the company to perform as good, if not better, than its largest peer Tata Consultancy Services (TCS) may have to wait a little longer. Infosys, the country’s second-largest software exporter reported slower sequential growth in revenue and profit than TCS for the June quarter (Q1). It also lagged on the fronts of employee attrition and growth in the banking, financial services, and insurance (BFSI) vertical.  Assumptions: I. On the positive side, Infosys continued to add large clients – four in the above $100-million billing category compared with the previous quarter. It continued to retain guidance of 6-8% revenue growth for FY19 while retaining the operating margin band of 22-24%. II. In the near term, the stock performance of TCS is likely to overshadow Infosys given the difference in their growth trajectories. III. The growth momentum of Infosys has slowed relative to TCS. The year-on-year growth in trailing 12-month (TTM) revenue of Infosys in each of the four quarters up to the June 2018 quarter has lagged TCS after leading in the previous five quarters.
A bacterial culture (200 μL containing 1.8 × 109 cells) was treated with an antibiotic Z (50 μg per mL) for 4 h at 37°C. After this treatment, the culture was divided into two equal aliquots.
Set A: 100 μL was plated on Luria agar.
Set B: 100 μL was centrifuged, the cell pellet washed and plated on Luria agar.
After incubating these two plates for 24 h at 37°C, Set A plate showed no colonies, whereas the Set B plate showed 0.9 × 109 cells. This experiment showed that the antibiotic Z is
The growth of bacteria (lactobacillus) in milk leads to curd formation. A minimum bacterial population density of 0.8 (in suitable units) is needed to form curd. In the graph below, the population density of lactobacillus in 1 liter of milk is plotted as a function of time, at two different temperatures, 25°C and 37°C. Consider the following statements based on the data shown above: I. The growth in bacterial population stops earlier at 37°C as compared to 25°C II. The time taken for curd formation at 25°C is twice the time taken at 37°C. Which one of the following options is correct?
Which of the following events occur during the stationary phase of bacterial growth?
P. Rise in cell number stops.
Q. Spore formation in some Gram-positive bacteria such as Bacillus subtilis.
R. Cell size increases in some Gram-negative bacteria such as Escherichia coli.
S. Growth rate of bacterial cells nearly equals their death rate.
T. Decrease in peptidoglycan cross-linking.
Consider the following statement
1. A bacterial food intoxication refers to food borne illnesses caused by the presence of a bacterial toxin formed in the food.
2. A bacterial food infection refers to food borne illnesses caused by the entrance of bacteria into the body through ingestion of contaminated foods and the reaction of the body to their presence or to their metabolites.
Which of the statements given above is/are correct?
Viral transduction is the process by which viruses carry bacterial DNA from one bacterial cell to another. In what way does this process play a role in bacterial evolution?
Determine the correctness or otherwise of the following Assertion (A) and Reason (R).
Assertion: Bacterial growth is called synchronous when majority of the cells are in same stage of the bacterial cell cycle.
Reason: Synchronous culture can be obtained by growing bacteria in an enriched medium
