Suppose that previously collected traffic data indicated that, during the afternoon rush hour, an average of 4 cars arrive at a toll bridge each second. If it is assumed that the cars arrive randomly, and can thus be modeled with a Poisson distribution, what is the probability that in the next second, NO cars will arrive. Solution lambda = mean number of cars crossing bridge each second = 4 probability that no cars arrive in next second = P(X=0) = 4^0/0! * e^-4 = 0.0183.

Firefly luciferase is a commonly used reporter gene. The gene origina.pdf
Firefly luciferase is a commonly used reporter gene. The gene originates from fireflies (a type of
beetle) and when it combines with its substrate, luciferin, light is produced. Luciferin is very
expensive to purchase. You would therefore like to figure out the biosynthetic pathway for
making luciferin so that you can get bacteria to make luciferin. This will enable you pay off all
your college loans! You have obtained 5 mutant firefly stocks that each fail to glow at night.
The flies in each stock have the wild type luciferase gene but ultimately fail to make the luciferin
substrate. Each stock has a unique mutation in one of the genes required to make luciferin. You
know that the biosynthesis of luciferin involves 5 intermediate compounds: A, B, C, D, and E.
However, you do not know the order that these compounds appear in the pathway. When you
feed these intermediate compounds to the mutant fireflies, they sometimes are able glow (+) and
sometimes still cannot glow (-). However, when you feed the mutant fireflies luciferin, they
always glow. Based on the results in the table above, write the biosynthetic pathway for
luciferin, showing the order of the intermediates (A-E) and the genes (M1-M5) required to
convert each intermediate to the next in the pathway.
Solution
This is a probem, where in you can get the answer by the means of trial and error.
Now that we have all pieces to this puzzle, lets join them.

Fergie has the choice between investing in State of New York bond at.pdf
Fergie has the choice between investing in State of New York bond at 10.2 percent and a
Surething bond at 11.5 percent. Assuming that both bonds have the same nontax characteristics
and that Fergie has a 30 percent marginal tax rate, in which bond should she invest?
Solution
After tax rate of return for Surething bond =11.5(1-0.3)=8.05%
Hence since State of New York bond has a higher rate of return;State of New York bond bond
must be invested upon..
Explain the “life” of a secreted protein molecule - trace the pathwa.pdf
Explain the “life” of a secreted protein molecule - trace the pathway in a cell by which a secreted
protein, such as an antibody, would be produced in an animal cell, starting in the nucleus.
Solution
Cells secrete proteins for their own cytosol or for release into surrounding extracellular fluid.
These secretions may include various hormones, digestive enzymes, antibodies, mucus etc.
The transcription process (conversion of DNA to mRNA) occurs inside the nucleus. This newly
formed mRNA is translated into proteins in the cytosol at cellular structures called ribosomes.the
ribosome remains in the cytosol if the protein has to be used within the cell, whereas if it is
destined for secretion outside the cell, the signal sequence (first few amino acids) is synthesized
on the ribosome and then the ribosome docks at the rough endoplasmic reticulum (RER) for
completion of protein synthesis. Proteins enter and cross endoplasmic recticulum (ER)
membrane co-translationally (i.e., they cross ER during synthesis of polypeptide). In the lumen
of ER, proteins undergo glycosylation and molecular chaperones aid in the process of protein
folding. Misfolded proteins are retrotranslocated to the cytosol, where they are degraded by a
proteasome action.
The vesicles with correctly folded proteins then enter the golgi appratus where further
posttranslational modifications occur including cleavage and functionalization. When the protein
moves through the entire Golgi apparatus, it buds off as secretion vesicles. Now, with the help of
cell\'s cytoskeleton, it moves towards the edge of the cell and attaches itself to the membrane.
Eventually, vesicle fuses with the cell membrane releasing its contents out of the cell through
the process of exocytosis.
This secretion pathway is followed for all protein molecules including antibodies..

7. Using to Table 1 to assist you, explain the rational for the diversity of the mycobiome, as
compared to the number of bacterial species identified in the lungs of CF patients. This should be
a full paragraph, not one or two sentences.
Solution
From the tabulated data given, it can be clearly noticed that majority of the population suffers
from ascomycete infections. Particularly, the most infectious species can be identified as
Candida albicans followed by C. dubliniensis. Saccharomyces cerevisiae infections are also very
high followed by C. parapsilosis and C. glabrata. Other types of infections are also evident in
patients but these organisms remain the most frequent infective agents for patients with cystic
fibrosis.
Since all of these microbes spread the disease from one organism to another, they are highly
communicable in nature. Also, since very high frequency of some of the species can be noticed
from the data, it is also suggested that the infections are opportunistic in nature i.e. they will
infect the individual as soon as his immunity against these microbes is minimized. Importantly,
since a huge population is suffering form nearly similar kind of infections, it can be suggested
that fixation of these microbial infections is possible in this population which can be clinically
deleterious in advanced stages because eradication of these microbes using multiple antibiotic
treatment would be difficult.
Hence, it can be evaluated from the data that the statisitical figures are clinically alarming and
demand immediate attention..

1. According to Mendel’s law of segregation :
2 . The Chromosomal Theory of Inheritance (Theodor Boveri and Walter Sutton --1903) was
consistent with Mendel\'s laws and the basic postulates were:
-----------------------These lead to the conclusion that both Sutton and Mendel predicted parental
types of gametes because in case of parental type , gametes are produced in equal proportion but
recombinant type produces gametes in unequal proportions.
Besides this , In 1911, after observing that linked traits could on occasion be inherited separately,
Thomas Hunt Morgan suggested that \"crossovers\" can occur between linked genes and
crossover is the prime reason for recombination.
With reference to Barth (2014), discuss how the author assessed the .pdf
With reference to Barth (2014), discuss how the author assessed the extent to which unmodified
historical cost, modified historical cost, and fair value measurement possess the qualitative
characteristics specified in the IFRS Conceptual Framework.
Solution
The conceptual framework in IFRS states the qualitative characteristics of the financial
statements to be useful which are as follows:
1. Fundamental : Fundamental qualitative characteristics are relevance and faithful
representation.
2. Enhancing: Enhancing qualitative characteristics are comparability, completeness, verifiablity
and understandability.
According to Barth(2014), Historical cost does not possess the qualitative characteristics of the
IFRS conceptual framework as it does not facilitates comparability and relevance but yes it is
sometimes relevant. The historical cost should be modified to use in financial statements, it
should be indexed for Inflation.
Modified historical cost possess the qualitative characteristics of the IFRS.
It is understandable, complete, accurate, but not considered as faithful representation. This is
widely used but both modified historical cost and unmodified historical cost lack meaning.
Whereas the Fair value presentation is more consistent with the new framework and hence it
should be widely used. This paper concludes that assets and liabilities at large should be
measured at fair value to provide the financial statements with the qualitative characteristics..

Solution
The characteristics of each microscope is as follows:
1.COMPOUND MICROSCOPE
In compound microscope the objective lens forms a real, inverted and magnified image of the
object. The eye piece acts like a magnifying glass and forms a virtual erect and magnified image.
Object is placed outside the principal focus of the objective lens. It consists of two convex lens,
ocular, close to the eye and s3cond objective lens. It also reduces chromatic abberrations.
2. STEREO (DISSECTING)
It is an optical microscope which is designed for low magnification, it uses light reflected from
the surfacevof an object rather than transmitted through it. It forms three dimensional erect
image as the prism under the eye piece reverses the image.
3. PHASE CONTRAST
It is used to examine biological tissues (live microorganisms). It is a type of light microscopy
that increases contrasts of transparent and colourless objects. This is achieved by influencing the
optical path of the light. Thus contrast of light and dark makes the specimen visible to the human
eye.
4. SCANNING (SEM).
It is used for producing high resolution images of a sample surface. The images have 3-D
appearance and best used to judge the surface structure of the sample. It produces image using
focused beam of electrons. In SEM, the picture is shown on the monitor.
5.TRANSMISSION (TEM).
It is based on transmitted electrons. It provides details of internal composition (show
morphology, crystallisation, stress or even magnetic domains of the sample). In TEM, picture is
shown on fluorescent screens. It provides 2-D picture of the sample. It uses electromagnetic
lenses to focus the electrons into very thin beams..

The zygomycota produce... septate hyphae with solid septate coenocy.pdf
The zygomycota produce... septate hyphae with solid septate coenocytic hyphae asexual
spores that are the most desiccation-resistant stage of the life cycle multi-nuleate zygosporangia
zygosporangia that are produced asexually two different types of spores: one through asexual
processes and one through sexual processes septate hyphae with a central pore
Solution
Zygomycotina contain about 1050 species of fungi. These fungi live in soil as saprophytes or
parasites on plants, insects and samll animals. The hyphae are coenocytic or multinucleate. The
hyphae are not septate but sepat are formed at the site of formation of gametangia. The
zygophores are produced during sexual reproduction and form zygosporangia by fusion of (+)
and (-) hyphae. Asexual spores formed include mitospores and chlamydospores. These spores are
dormant and desiccation resistant. Options 2, 3 and 6 are correct..

Three people get into an elevator at the ground floor of 12 story bu.pdf
Three people get into an elevator at the ground floor of 12 story building. Assuming each person
is equally likely to get off at each floor, what is the probability that they get off at the same
floor?
Solution
There are 12^3 ways to get off at any floor they want.
Now, there are 12 ways to get off all at the same floor.
thus,
P(same floor) = 12 / (12^3) = 1/144 or 0.006944444 [ANSWER].

Dr. Cardenas studied political attitudes among di erent groups of 20.pdf
Dr. Cardenas studied political attitudes among di erent groups of 20-, 40-, and 60- year- olds.
Political attitudes were found to be most conservative in the age-60 group and least conservative
in the age-20 group. What type of method was used in this study? Can you conclude that people
become more politically conservative as they get older? Why or why not? Propose alternative
ways of studying this topic.
Solution
This is an observational study. If it is an experimental design, we need to perform Chi-square
test, odds ratio, or one way ANOVA. Or simply, if the data is available for each age group, the
coefficient of variation is used to determine which age group is conservative..

Suppose earthquake A measures 3.2 on the Richter Scale. What was the Richter scale measure
of earthquake B if it was 1900 times more powerful than earthquake A?
Solution
Msf = log(Isf/S)
8.3 = log(Isf/S)
Now Msa = log(Isa/S)
Given Isa = 1900Isf
So, Msa = log(1900Isf/S)
= log 1900 + log(Isf/S)
= 3.278 + 3.2
= 6.478.

What type of gametes did Sutton predict Mendel (parental, recombin.pdf
What type of gametes did Sutton predict? Mendel? (parental, recombinant, both)
Solution
1. According to Mendel’s law of segregation :
2 . The Chromosomal Theory of Inheritance (Theodor Boveri and Walter Sutton --1903) was
consistent with Mendel\'s laws and the basic postulates were:
-----------------------These lead to the conclusion that both Sutton and Mendel predicted parental
types of gametes because in case of parental type , gametes are produced in equal proportion but
recombinant type produces gametes in unequal proportions.
Besides this , In 1911, after observing that linked traits could on occasion be inherited separately,
Thomas Hunt Morgan suggested that \"crossovers\" can occur between linked genes and
crossover is the prime reason for recombination.
With reference to Barth (2014), discuss how the author assessed the .pdf
With reference to Barth (2014), discuss how the author assessed the extent to which unmodified
historical cost, modified historical cost, and fair value measurement possess the qualitative
characteristics specified in the IFRS Conceptual Framework.
Solution
The conceptual framework in IFRS states the qualitative characteristics of the financial
statements to be useful which are as follows:
1. Fundamental : Fundamental qualitative characteristics are relevance and faithful
representation.
2. Enhancing: Enhancing qualitative characteristics are comparability, completeness, verifiablity
and understandability.
According to Barth(2014), Historical cost does not possess the qualitative characteristics of the
IFRS conceptual framework as it does not facilitates comparability and relevance but yes it is
sometimes relevant. The historical cost should be modified to use in financial statements, it
should be indexed for Inflation.
Modified historical cost possess the qualitative characteristics of the IFRS.
It is understandable, complete, accurate, but not considered as faithful representation. This is
widely used but both modified historical cost and unmodified historical cost lack meaning.
Whereas the Fair value presentation is more consistent with the new framework and hence it
should be widely used. This paper concludes that assets and liabilities at large should be
measured at fair value to provide the financial statements with the qualitative characteristics..

Three people get into an elevator at the ground floor of 12 story bu.pdf
Three people get into an elevator at the ground floor of 12 story building. Assuming each person
is equally likely to get off at each floor, what is the probability that they get off at the same
floor?
Solution
There are 12^3 ways to get off at any floor they want.
Now, there are 12 ways to get off all at the same floor.
thus,
P(same floor) = 12 / (12^3) = 1/144 or 0.006944444 [ANSWER].
The F statistic in a multiple regression is significant if at least .pdf
The F statistic in a multiple regression is significant if at least one of the predictors has a
significant t statistic at a given ?.TrueFalse
Solution
True, F test in ANOVA has null hypothesis that all slope coefficients are zero, and when this is
rejected, it means that atleast one coefficient (predictor) is significant..
Dr. Cardenas studied political attitudes among di erent groups of 20.pdf
Dr. Cardenas studied political attitudes among di erent groups of 20-, 40-, and 60- year- olds.
Political attitudes were found to be most conservative in the age-60 group and least conservative
in the age-20 group. What type of method was used in this study? Can you conclude that people
become more politically conservative as they get older? Why or why not? Propose alternative
ways of studying this topic.
Solution
This is an observational study. If it is an experimental design, we need to perform Chi-square
test, odds ratio, or one way ANOVA. Or simply, if the data is available for each age group, the
coefficient of variation is used to determine which age group is conservative..

Suppose earthquake A measures 3.2 on the Richter Scale. What was the Richter scale measure
of earthquake B if it was 1900 times more powerful than earthquake A?
Suppose earthquake A measures 3.2 on the Richter Scale. What was the Richter scale measure
of earthquake B if it was 1900 times more powerful than earthquake A?
Solution
Msf = log(Isf/S)
8.3 = log(Isf/S)
Now Msa = log(Isa/S)
Given Isa = 1900Isf
So, Msa = log(1900Isf/S)
= log 1900 + log(Isf/S)
= 3.278 + 3.2
= 6.478.

2024.06.01 Introducing a competency framework for languag learning materials ...
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Suppose that previously collected traffic data indicated that, durin.pdf
- 1. Suppose that previously collected traffic data indicated that, during the afternoon rush hour, an average of 4 cars arrive at a toll bridge each second. If it is assumed that the cars arrive randomly, and can thus be modeled with a Poisson distribution, what is the probability that in the next second, NO cars will arrive. Solution lambda = mean number of cars crossing bridge each second = 4 probability that no cars arrive in next second = P(X=0) = 4^0/0! * e^-4 = 0.0183
