- As described in Figure, host DNA is hydrolyzed into smallpieces, which are occasionally assembled with phage proteins, creatinga phage with bacterial chromosomal DNA. If the breakage ofthe chromosomal DNA is not random (i.e., it is more likely tobreak at certain spots as opposed to other spots), how might nonrandombreakage affect cotransduction frequency?The diagram shows SEIV model of measles for children under pre-school. fl μ (1-P)A S BSI PA E V O T I In the transfer diagram, ^ is the rate at which individuals are born, p is the fraction of infants who are vaccinated, ß is the rate at which susceptible individuals become infected by those who are infectious, is the natural death rate, o is the rate at which exposed individuals become infectious, and is the rate at which infected individuals are treated and recovered with permanent immunity.Can you give a clear explanations of the introduction for this paper? Please explain as if your presenting a group presentation about this paper introduction.
- Understanding the life cycle of Plasmodium is important and we know that it is spread via mosquitos. The mosquito serves as O a mechanical vector in which the pathogen does not need the vector for replication O a biological vector in which the pathogen does not need the vector for replication O a mechanical vector in which the mosquito serves as a host for the multiplication of the pathogen during some stage of the pathogen's life cycle O a biological vector in which the mosquito serves as a host for the multiplication of the pathogen during some stage of the pathogen's life cycle Question 34 Patients are becoming inherently resistant to malaria resulting from O Sporogenic cells traveling a shorter distance O Climate changes O Genetic deficiency of glucose-6-phosphate dehydrogenase O Decrease in mosquito numbers 12 ....Antigenic shifts in influenza viruses are represented by dra-matic changes in the viral antigens. It is likely they arise fromrare events in which:(a) Two different influenza viruses infect a cell at the sametime(b) Two separate viruses undergo lysogenic conversion(c) Two viruses conjugate(d) Mutations accumulate(e) All of the aboveEach species of bacteria has its own distinctive cell surface. Thecharacteristics of the cell surface play an important role in processessuch as conjugation and transduction. For example, certainstrains of E. coli have pili on their cell surface. These pili enableE. coli to conjugate with other E. coli and also enable certain bacteriophages (such as M13) to bind to the surface of the E. coli andgain entry into the cytoplasm. With these ideas in mind, explainwhich forms of genetic transfer (i.e., conjugation, transduction,and transformation) are more likely to occur between different speciesof bacteria. Discuss some of the potential consequences ofinterspecies genetic transfer.
- The SIR model of pandemics (such as COVID-19) considers three variables: S (those susceptible to the disease) I (those infected with the disease), and R (those recovered or removed from the illness). This model has a system of three differential equations, one for the derivative of each variable. We viewed the video entitled "The Coronavirus Curve - Numberphile," and we also rebuilt this model in Geogebra ourselves. That model includes two constants, "transm" and "recov:" use Ct instead of "transm," and use cr instead of "recov." In Geogebra, we could tweak these values. a. In this system, what is the equation for S'(t) = dS/dt? b. In this system, what is the equation for I'(t) = dI/dt? c. In this system, what is the equation for R'(t) = dR/dt? d.

Explain in four to five sentences.
- Your roommate left the deviled eggs out on the counter for 8 hours, but is happily eating them for breakfast. "We learned that bacteria take 20 minutes to reproduce at room temperature," he explains, "so I figure at most there's only a couple hundred in there. No big deal." What is your response, after remembering the equation N Noert, and the fact that e is roughly equal to 2.72? %3D O The intrinsic rate of increase (r) is only equal to 2, since each bacterium divides in half. No big deal. Hand me a fork! O If just 1 dangerous bacterium landed on your egg at the beginning of the night, there would now be approximately 1.7 million. They have been growing exponentially all night! You might be okay, but better not risk it. O If just 1 dangerous bacterium landed on your egg at the beginning of the night, there would now be nearly 27 billion. They have been growing exponentially all night! Call me if you need a ride to the hospital later. So the population only doubled 3 times for every…nich TWO of the following statements about Extended Spectrum ß-lactamases are CORRECT? O Extended Spectrum ß-lactamases can inactivate all B-lactam antibiotics except third generation antibiotics in this family. O Genetic material encoding for extended spectrum ß-lactamases are easily transferred to other bacteria via transduction. O Extended Spectrum ß-lactamases are frequently produced in Klebsiella sp. and Escherichia coli strains. O Many Extended Spectrum ß-lactamases are not inhibited by clavulanic acid and other B-lactamase inhibitors. OSome Extended Spectrum ß-lactamases-producing E. coli are still sensitive to penicillins.
