In the 19th century, cavalries were still an important part of the European military complex. While horses have many wonderful qualities, they can be dangerous beasts, especially if poorly treated. The Prussian army kept track of the number of fatalities caused by horse kicks to members of 10 of their cavalry regiments over a 20-year time span. If these fatalities occurred independently and with equal probability for each regiment, then the number of deaths by horse kick per regiment per year should follow a Poisson distribution. On the other hand, if some regiments during some years consisted of particularly bad horsemen,12 then the events would not occur with equal probability, in which case we would expect a frequency distribution different from the Poisson distribution. The following table shows the data, expressed as the number of fatalities per regiment-year (Bortkiewicz 1898): a) Test whether a Poisson distribution fits these data. \begin{tabular}{cc} Number of deaths ( X ) & Number of regiment-years \\ \hline 0 & 109 \\ 1 & 65 \\ 2 & 22 \\ 3 & 3 \\ \hline 4 & 1 \\ \hline 4 & 0 \\ \hline Total & 200 \\ \hline \end{tabular}.

In Table 19.1 are listed the average distance from the Sun, r , in Astronomical Units (AUs), and the average orbital velocity, v , in kilometers per second ( km / sec ) , for each of the eight planets of the solar system. 1. Plot the planetary distance and velocity data from Table 19.1 on the axes of Figure 19.2 on the worksheet. 2. Describe the trend of the planets' orbital velocities with increasing distance from the Sun (a centrally concentrated mass) according to the data points in Figure 19.2. Be specific. TABLE 19.1 Planetary Distance and Orbital Velocity Data The Milky Way Galaxy: A Dispersed Distribution of Mass Our solar system lies in the outskirts of the Milky Way, a vast, rotating, disk-shaped assemblage of stars, gas, and dust more than 100,000 light-years across. Table 19.2 lists observational data for celestial objects found at various locations within the Milky Way's disk: r is the object's distance, or radius, from the galactic center, in units of kiloparsecs (kpc), where 1 kpc = 1 , 000 parsecs (about 3,260 light- years), and v is the object's orbital velocity around the galactic center in kilometers per second ( km / s ) . Taken together, this array of orbital velocities traces out the Galaxy's pattern of rotation. 3. Plot the galactic radius and velocity data from Table 19.2 on the axes of Figure 19.3 on the worksheet. 4. (a) Describe the trend of celestial objects' orbital velocity with increasing distance from the galactic center, according to the data points in Figure 19.3.

In spite of the contribution of plasmids to the spread of antibiotic resistance in human pathogens, little is known about the transferability of various drug resistance plasmids in bacterial biofilms. The goal of this study was to compare the efficiency of transfer of 19 multidrug resistance plasmids into Escherichia coli recipient biofilms and determine the effects of biofilm age, biofilm-donor exposure time, and donor-to-biofilm attachment on this process. An E . coli recipient biofilm was exposed separately to 19 E. coli donors, each with a different plasmid, and transconjugants were determined by plate counting. With few exceptions, plasmids that transferred well in a liquid environment also showed the highest transferability in biofilms. The difference in transfer frequency between the most and least transferable plasmid was almost a million-fold. The 'invasibility' of the biofilm by plasmids, or the proportion of biofilm cells that acquired plasmids within a few hours, depended not only on the type of plasmid, but also on the time of biofilm exposure to the donor and on the ability of the plasmid donor to attach to the biofilm, yet not on biofilm age. The efficiency of donor strain attachment to the biofilm was not affected by the presence of plasmids. The most invasive plasmid was pHH2-227, which based on genome sequence analysis is a hybrid between IncU-like and IncW plasmids. The wide range in transferability in an E . coli biofilm among plasmids needs to be taken into account in our fight against the spread of drug resistance..

In some goats, the presence of horns is produced by an autosomal gene that is dominant in males and recessive in females. A horned female is crossed with a hornless male. The F 1 offspring are intercrossed to produce the F2. What proportion of the F 2 females will have horns? A series of two-point crosses were carried out among 7 loci producing the following recombination frequencies. Map the 7 loci on their respective chromosome(s) and the distance between the loci of each group. 1In Drosophila (fruit flies), yellow body is due to an X inked gene that is recessive to the genes for gray body. A homozygous gray female is crossed with a yellow male. The F 1 are intercrossed to produce F 2 . Give the genotypes and phenotypes, along with the expected phenotypes of the F 1 and F 2 progeny..

In these unprecedented times with the country recovering from a pandemic, I know that those working the in the criminal justice system were facing challenges not previously experienced. Police had to deal with citizens directly. Probation/Parole Officers had to deal with offenders on supervision. Corrections Officers had to deal with prisoners. The court system had to function. So, do a little research and (1) find out what a specific police agency, (2) a specific probation/parole department, (3) a specific jail or prison and (4) a specific county court system was doing to manage all this during the Covid pandemic. This information should be available on the various websites. It has been also reported in the media. Respond in four specific paragraphs numbered 1 through 4.

In the section "Investigating Life: Genetic Messages from Ancient Ecosystems," what was the advantage of looking for DNA samples in permafrost? Areas with permafrost are older than other parts of the world, allowing scientists to collect samples back 1.5 to 2 million years. The freezing temperatures preserve the DNA. Most plants and animals evolved in Siberia. It is easier to take solid core samples. The enzymes that make DNA are still active in the cells..
