In the 14th century- the bubonic plague killed more than 2-3 of Europe (1).pdf
In the 14th century, the bubonic plague killed more than 2/3 of Europeans. The plague
was transmitted by fleas who were infected by rats and would inject a bacteria into the
bloodstream that shuts down a person's immune system. While not as common today,
the bubonic plague still exists, infecting around a thousand people a year. There are
about seven cases in the United States each year, many of those in Arizona and New
Mexico. Scientists have discovered that the bacteria works by affecting signaling
pathways in the immune system.
Based on what you know so far, which of these pathways do you think is the most
likely?

In the 19th century- cavalries were still an important part of the Eur.pdf
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 &

In spite of the contribution of plasmids to the spread of antibiotic r.pdf
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.pdf

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

How would you represent this object in Python?.
In these unprecedented times with the country recovering from a pandem.pdf
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. Identify the specific websites you used..

In the section -Investigating Life- Genetic Messages from Ancient Ecos.pdf
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..
