a case study on additive manufacturing Solution Hydrauilc block manifold redesigned for additive manufacturing Additive manufacturing (AM) is highly suited for the design and manufacture of manifolds due to its ability to build internal features and passageways. Renishaw has collaborated with a customer to redesign their current hydraulic block manifold with additive manufacturing in mind. The main goal of the project was to reduce the mass of the component whilst retaining its robustness. Due to the increased design freedom associated with additive manufacturing, an opportunity to increase the efficiency of the flow paths was also identified..

In a Davis U-tube experiment, you add a different strain of auxotroph.pdf
In a Davis U-tube experiment, you add a different strain of auxotrophic bacteria to each side of
the apparatus. After allowing time for growth, you transferred and grew the bacteria on a plate
with minimal medium and noticed the growth of prototrophs. By which process did this genetic
transfer possibly occur if... There was DNase enzyme (breaks down free-floating DNA) present
in the medium? There was no DNase enzyme in the medium? There was DNase enzyme
present in the medium and the sintered glass filter was removed from the U-tube apparatus (no
separation between bacterial strains)? Answer the following questions with F^+, F^-, or Hfr.
More than one of these three may apply to a single question. Bacterium that does not have an F
factor. Bacterium that can donate an F factor.
Solution
Answer:
4. For DNA transfer to take place through conjugation between the two different bacteria,
physical contact is necessary.
a. When DNase is present, it can cleave any naked DNA present in the media. So, the only way
that can transfer DNA from one bacterial auxotroph to the other is through transduction (if the
media is contaminated with a bacteriophage) or through physical contact, i.e, conjugation (if the
sintered glass filter is defective).
b. When there is no DNase, the most probable mechanism of gene transfer is transformation
(transfer of naked DNA).
c. In this case, there can be physical contact between the two auxotroph strains. So, gene transfer
probably took place through conjugation.
5. a. Bacteria that does not have a F factor: F-
b. Bacteria that can donate a F factor: F+
( Hfr strains cannot transfer the F-factor efficiently to the F- strain due to the short duration of
conjugation tube formation).
If HDL levels were given in the dataset as a continuous (quantitativ.pdf
If HDL levels were given in the dataset as a continuous (quantitative) variable, and all the other
variables were still given as dichotomous variables, which of the following statistical tools we
can use to explore the relationship between a continuous quantitative DV and one or more binary
IVs (binary means taking only two values)? (choose all the correct answers).
T-test, ANOVA, or Regression?
Solution
As one variable is dichotomous therefore we will use t test in order to test sifgnificant diffrence
between mean of two levels of dichotomous variable..
I dont really know what two factor analysis is All my study guid sa.pdf
I dont really know what two factor analysis is? All my study guid says is to know what two
factor analysis, three factor anaylsis and tetrad anaylsis. Then it gives the things you should
know in each topic. THis is for Genetics.
Two factor analysis:
1) You should know how to determine the genotype (write it properly) of individuals based on
phenotype and phenotype based on genotype.
2) You should know cis and trans organization of alleles in a diploid organism.
3) Determine map distance between genes based on recombination frequency
4) You should be able to determine progeny size of different genotypes based on genetic map
and map distance. (distinguish between map position and map distance)
5) Know test cross and F2 analysis of linked and independently assorting genes. .
6) Show know how to do genetic analysis of organisms where recombination is seen in both
male and female gametogenesis and organisms where recombination is absent in males.
Solution
1. The phenotype means the external appearance of an organism. It is the observable
characteristics of any indivudual. As if we say the plant is tall having green and round seeds and
purple flowers, so the characters such as tall, green, round and purple are the phenotypic
characters of that plant.
Genotype refers to the genetic makeup of an individual. It constitutes the set of genes, whuch
decides the phenotype of organism.
Such as TTRR this is genotype of a homozygous tall plant having round seeds..

essay on elderly patients in rural areas having problems meeting health care needs due to
transportation
Solution
Many elderly patients who are above 60 years old have been facing higher complex situations
with respect to their health due to low transportation facilities across the country. This is due to
lack of both federal and state \"transportation health care budgets\" to implement health care
facilities including adequate rural transportation services finally making elderly people difficult
to their health care access those who have been suffering from dementia, diabetes and
neurodegenerative diseases. Therefore, the health care needs including accident and emergency
services to the rural pediatric patients are lower compared to the urban health care facilities so
that it is crucial to improve essential public transportation systems to bring these pediatric
patients to provide them with essential care.

Define liquidity and why money is said to be the most liquid of all .pdf
Define liquidity and why money is said to be the most liquid of all assets.
Solution
Liquidity is defined as the speed with which one asset can be converted into another asset that
can be instantly used as cash (for transaction purposes).
In this sense, money is the most liquid asset. Cash is already an asset that can be exchanged for
any purpose, but other components of money, for example checking deposits, savings, certificate
of deposits etc, can be concerted into cash at fastest possible time, therefore they are considered
most liquid of all assets. In contrast we can consider a farm-house which is a salable asset, but
selling it and getting cash for it takes much time, so it has very low liquidity..

Compare and contrast eukaryotic and prokaryotic cells. Why do you th.pdf
Compare and contrast eukaryotic and prokaryotic cells. Why do you think their endomembrane
systems are different, is evolution involved? Paragraph format please, be very detailed and the
answer is expected to be long!
Solution
Prokaryote,relatively simple unicellular organism lacking a nucleus and other features found in
the more complex cells of all other organisms,called eukaryotes.In 1938 American biologist
Herbert Copeland proposed that unicellular organisms lacking nuclei be classified in their own
kingdom, Monera, also called Kingdom Prokaryotae.All bacteria were categorized in this newly
established kingdom. This scheme was the first to establish separate kingdoms for prokaryotes
(organisms without nuclei) and eukaryotes (organisms with nuclei).In 1990 American
microbiologist Carl Woese proposed that bacteria be divided into two groups,the archaea,or
archaebacteria,and bacteria, based on their structural and physiological differences.In some
classification systems,the archaea are considered prokaryotes;in others, they are classified in
their own domain, the archaea.Archaebacteria consist of a small group of primitive anaerobes
(organisms that do not require oxygen).They are found in a narrow range of habitats–often in
extreme environments with high temperature,high salt,or high acidity.In contrast, bacteria live in
a wide range of environments with or without oxygen, at various temperatures, and at various
levels of acidity.
In both prokaryotes and eukaryotes,the plasma membrane is composed of two layers of
phospholipid molecules interspersed with proteins,and regulates the traffic that flows in andout
of the cell.The prokaryotic plasma membrane,however,carries out additional functions.It
participates in replication of deoxyribonucleic acid (DNA) for cell division andsynthesis of
adenosine triphosphate (ATP),an energy molecule.In some prokaryotes,the plasma membrane is
essential for photosynthesis,the process that uses light energy to convert carbon dioxide and
water to glucose.
Fossil records indicate that eukaryotes evolved from prokaryotes somewhere between 1.5 to 2
billion years ago.Two proposed pathways describe the invasion of prokaryote cells by two
smaller prokaryote cells.They subsequently became successfully included as part of a now much
larger cell with additional structures and capable of additional functions.They are Endosymbiosis

Which intermolecular porcess primarly drives the formation of a bila.pdf
Which intermolecular porcess primarly drives the formation of a bilayer when phospholipids are
added to water? Which intermolecular porcess primarly drives the formation of a bilayer when
phospholipids are added to water?
A-Lipids cause water to arrange in an ordered, unfavorable cage-like structure.
B-Forcing lipids into a bilayer reduces this effect.
C-The ordered arrangement of a bilayer is more favorable than the disordered state of individual
free-floating phospholipids.
D-A bilayer arrangement maximizes the strength of hydrophobic interactions among
phospholipids.
E-Phospholipids self-assemble inot a bilayer due to the strong affinity they have for each other.
Solution
Thanks for your query.
As the lipid bilayer forms the surface of the cell. there is an important point that we have to
understand here., That is the lipid cell is hydrophilic on one end and hydrophobic on the other
end. Therefore, the hydrophobic ends of both cells join in the center of the lipid bilayer and the
hydrophilic ends expose themselves to the outer surface and the inner surface. Since they are
hydrophilic they can easily interact with the fluids they are exposed to unlike the hydrophobic
ends.
Therefore the correct option is D

Which of the following is an example of a translocation a chromosom.pdf
Which of the following is an example of a translocation? a chromosome containing the mutant
sickle cell allele Two chromosomes have experienced breaks at their terminal ends (e.g.,
chromosome 6 and 18), and during the rejoining process, the ends get switched. The end of
chromosome 6 becomes attached to chromosome 15 and vice verse an occurrence of
nondisjunction at meiosis I an occurrence of nondisjunction at meiosis
Solution
Answer: Translocations are chromosomal abnormalities which occur when chromosomes break
and the fragments rejoin to other chromosomes. It is of 2 types which are reciprocal and non-
reciprocal translocation. reciprocal one show normal phenotype as compare to the other one, so
option second is most appropriate example of chromosomal translocation..
What is simplicity and how does it bear on the acceptability of a sc.pdf
What is simplicity and how does it bear on the acceptability of a scientific hypothesis?
Solution
Simplicity - simpler means fewer assumptions. Consider Newtons mechanics and copernican
hypothesis . They both stand as examples of generality and simplicity. Newton with help of
previous general set of laws explained laws of motion for terrestial and heavenly bodies.
Copernicus explained the same observational data with simpler assumptions. The virtues are not
independent and in some cases it overlaps. In some cases generalisation will be simplification.
Simplicity is used for describing philosophical theories . In general if a hypothesis is more
simpler it can be confirmed . In some cases precision overlaps simplicity. The reality is part of
quine pervasive scientific realism. Quine quotes for simplicity. Quine also quotes that different
classes or groups can be clearly dealt only if is in simpler explanatory view and relative
simplicity of the system. Hence a scientific theory should not be generalised but should be in
simplified form..
What’s the difference between soluble and insoluble fiberWhy is f.pdf
What’s the difference between soluble and insoluble fiber?
Why is fiber indigestible? After all, isn’t cellulose just a string of glucose
molecules, similar to amylose?
What are some of the benefits of increasing fiber intake?
How does fiber confer these benefits?
What are some of the potential pitfalls of consuming excess fiber?
How does fiber confer these detriments?
What are the general recommendations for fiber intake?
We refer to some of our fibers as prebiotics. What does that term really mean? How does a
prebiotic aid gut health?
Solution
What’s the difference between soluble and insoluble fiber?
ANS: In short soluble fibres dissolve in water and insoluble fibres do not.
Soluble fibre makes our food more viscous when in a digestive tract. Soluble fibre traps food
components thus making them less absorbable. Insoluble fibre absorbs water for example how
dry sponge expands after soaking up water. Insoluble fibres are helpful in treating constipation.
Why is fiber indigestible? After all, isn’t cellulose just a string of glucose molecules, similar to
amylose?
ANS: What makes fibre indigestible is the lack of enzymes in humans to break down the
glycosidic bond in fibre.
What are some of the benefits of increasing fiber intake?
ANS: Benefits of fibre intake include:
gastrointestinal disorders
lowering cholesterol levels
lowering the risk of colon cancer
weight loss
How does fiber confer these benefits?
ANS: fibre has three mechanisms of action, which are bulking, viscosity and fermentation.
Fibres can use all three mechanisms or only one.
Bulking fibres absorb water and increase stool weight and regularity. Bulking fibres can be
minimally fermented or not fermented.
Viscous fibres thicken the content of the intestinal tract . They mix with water and form a
gelatinous mass. Depending on the type of viscous fibre, they are minimally, partially,
completely fermented or not fermented at all.
Fermentable fibres are used as food source for the microbes that exist on our large intestine.
What are some of the potential pitfalls of consuming excess fiber?
ANS: As fibre is not digested, too much fibre causes the digestive tracts to process it slowly, it
can lead to bloating, constipation, abdominal discomfort and gas. If constipation is prolonged, it
can lead to intestinal blockage. during intestinal blockage there can be malabsorption and
accumulations of toxins in the body..

What would you conclude if an inoculated plate had colonies between the streak lines?
Solution
It depends, if there is no growth or colony appearance on streak line and only it shows growth in
between streak line then it is certainly a contamination.If there are colonies on streak line and not
resemble with the streak culture then also it is a contamination but there can be a chance that
colony appears due to some fault in streaking procedure and the inoculum drops between the
streak line..

The U.S. government subsidizes flood insurance because those who wan.pdf
The U.S. government subsidizes flood insurance because those who want to buy it live in the
flood plain and cannot get it at reasonable rates. What inefficiency does this create
Solution
As Hurricane Sandy continues to batter the Eastern seaboard of the U.S., one thing is for certain:
insurance companies will be ponying up for billions of dollars in property damage caused by
high winds. Last year’s Hurricane Irene cost insurance providers more than $4 billion in damage
claims, with flood-insurance payments totaling nearly $1.3 billion.
But what many Americans may not know is that this $1.3 billion was a bill footed by the federal
government, which underwrites the vast majority of flood insurance across the nation.
Historically, insurance companies have been wary of offering flood insurance to homeowners
because the risks associated with flood insurance are difficult to forecast, so any private
insurance that had been offered was prohibitively expensive for average homeowners.
But in the 1960s, frequent flooding of the Mississippi River was driving up the costs of federal
disaster-relief programs. In an effort to reduce these costs,Congress set up the National Flood
Insurance Program (NFIP) to provide flood insurance to the general public and promote effective
floodplain management. Under the program, homeowners in certain areas of the U.S. are
required to buy flood insurance, and communities that hope to benefit from the program have to
enforce city-planning regulations set out by FEMA, which manages NFIP.
(MORE: Banks Waive Fees for Residents in Path of Hurricane Sandy)
Though the program has been effective at making flood insurance widely available, a growing
chorus of critics from environmentalists to libertarians has been attacking it for encouraging
homeowners to build recklessly in areas that are prone to flooding. For instance, Ira Stoll wrote
yesterday in the New York Sun:
“Hurricane casualties are partly the result of unintended consequences of government actions:
without federal flood insurance, many fewer people would take the risk of living in low-lying
areas vulnerable to storm surges.”
There is evidence to support the view that the government is actually encouraging citizens to live
in areas most in danger of flood damage. According to a 2010 report issued by the Institute for
Policy Integrity, Congress has historically set the premium rate too low for flood insurance —
effectively subsidizing building in flood-prone areas at the expense of taxpayers at large. This
practice has helped drive the fund $19 billion in debt, caused mostly by the unusually severe
damage caused by Hurricane Katrina.
In addition, the report argued that the environmental effects of the federal government’s flood-
insurance policy may be more severe than the financial effects. According to the report:
“River basins and coastal zones provide natural purification of water and wastewater; erosion
control and weather mitigation; and habitat for fish and wildl.

The Darwinian revolution challenged traditional views of a young Eart.pdf
The Darwinian revolution challenged traditional views of a young Earth inhabited by
unchanging species. What were the prevailing thoughts about the Earth and the organisms on it
prior to Darwin? What was Darwin\'s big idea? How does it differ from previous ideas
explaining the diversity of life on Earth? What is the \'Scala Naturae\', who advanced this
concept and why was it so widely accepted? What is \'Systema Naturae\', who advanced this
concept and why so accepted? Who are these people did we talk about them? How are their ideas
relevant to a conversation about evolution? Malthus, Linneaus, Hutton, Lyell, cuvier, Lamarck,
Aristotle, Darwin, Mendel, Wallace What did Lamarck propose as an explanation for how
organisms change over time? Explain how Lamarck\'s ideas are not supported by evidence?
Descent with modification by means of natural selection explains the adaptations of organisms
and the unity and diversity of life What did Darwin do that most influenced his worldview (what
is a worldview)? What were the critical observations Darwin made on his voyage of discovery?
What two main ideas did Darwin develop in the \"Origin of Species\"? What is natural
selection? (Look at the lecture powerpoints to answer the question) What are three main points
and important considerations regarding natural selection? What is an adaptation? What are the
two observations and two inferences that explain how natural selection leads to adaptive
evolution? What role did artificial selection play in the development of Darwin\'s logic for
natural selection? What does the theory of evolution suggest will happen when environments
favoring one adaptation change?
Solution
Ques-1: What were the prevailing thoughts about the young Earth and the organisms on it prior
to Darwin
The prevailing thoughts about the young Earth and the organisms on it prior to Darwin are
creatures were created by supernatural power & human are going to control these creatures and
populations are unchanging on the young Earth. Theory of evolution of “Darwin” has produced
specific impact on the imperialism and biblical view of origin of the species finally affected
contemporary philosophical views of religion & creation. These views have changed socio-
economical perspectives in the society about the culture finally changed the “religious views of
humans that “human race has evolved from God’s creation & God’s image”.
Ques-2: What was Darwin\'s big idea?
Answer:
Darwin theory of evolution is completely based on genetic variations and natural selection
operating on the species to acquire adaptations followed by unfit species are going to extinct.
However, here the extinction is not based on designer as it is due to nature. Nature selects
species, which are fit into it followed by elimination that is unfit in nature. It is different from
previous ideas of Earth species diversity, in which creation was completely relies upon myths
and God, the “religious views of humans that “human race has evo.
The average length of crocodiles in a swamp is 13 feet. If the lengt.pdf
The average length of crocodiles in a swamp is 13 feet. If the lengths are normally distributed
with a standard deviation of 2.2 feet, find the proportion of crocodiles more than 14.7 feet long.
Round your answer to two decimal places
Solution
Normal Distribution
Mean ( u ) =13
Standard Deviation ( sd )=2.2
Normal Distribution = Z= X- u / sd ~ N(0,1)
P(X > 14.7) = (14.7-13)/2.2
= 1.7/2.2 = 0.7727
= P ( Z >0.773) From Standard Normal Table
= 0.2198.

Compare and contrast eukaryotic and prokaryotic cells. Why do you th.pdf
Compare and contrast eukaryotic and prokaryotic cells. Why do you think their endomembrane
systems are different, is evolution involved? Paragraph format please, be very detailed and the
answer is expected to be long!
Solution
Prokaryote,relatively simple unicellular organism lacking a nucleus and other features found in
the more complex cells of all other organisms,called eukaryotes.In 1938 American biologist
Herbert Copeland proposed that unicellular organisms lacking nuclei be classified in their own
kingdom, Monera, also called Kingdom Prokaryotae.All bacteria were categorized in this newly
established kingdom. This scheme was the first to establish separate kingdoms for prokaryotes
(organisms without nuclei) and eukaryotes (organisms with nuclei).In 1990 American
microbiologist Carl Woese proposed that bacteria be divided into two groups,the archaea,or
archaebacteria,and bacteria, based on their structural and physiological differences.In some
classification systems,the archaea are considered prokaryotes;in others, they are classified in
their own domain, the archaea.Archaebacteria consist of a small group of primitive anaerobes
(organisms that do not require oxygen).They are found in a narrow range of habitats–often in
extreme environments with high temperature,high salt,or high acidity.In contrast, bacteria live in
a wide range of environments with or without oxygen, at various temperatures, and at various
levels of acidity.
In both prokaryotes and eukaryotes,the plasma membrane is composed of two layers of
phospholipid molecules interspersed with proteins,and regulates the traffic that flows in andout
of the cell.The prokaryotic plasma membrane,however,carries out additional functions.It
participates in replication of deoxyribonucleic acid (DNA) for cell division andsynthesis of
adenosine triphosphate (ATP),an energy molecule.In some prokaryotes,the plasma membrane is
essential for photosynthesis,the process that uses light energy to convert carbon dioxide and
water to glucose.
Fossil records indicate that eukaryotes evolved from prokaryotes somewhere between 1.5 to 2
billion years ago.Two proposed pathways describe the invasion of prokaryote cells by two
smaller prokaryote cells.They subsequently became successfully included as part of a now much
larger cell with additional structures and capable of additional functions.They are Endosymbiosis

Which intermolecular porcess primarly drives the formation of a bila.pdf
Which intermolecular porcess primarly drives the formation of a bilayer when phospholipids are
added to water? Which intermolecular porcess primarly drives the formation of a bilayer when
phospholipids are added to water?
A-Lipids cause water to arrange in an ordered, unfavorable cage-like structure.
B-Forcing lipids into a bilayer reduces this effect.
C-The ordered arrangement of a bilayer is more favorable than the disordered state of individual
free-floating phospholipids.
D-A bilayer arrangement maximizes the strength of hydrophobic interactions among
phospholipids.
E-Phospholipids self-assemble inot a bilayer due to the strong affinity they have for each other.
Solution
Thanks for your query.
As the lipid bilayer forms the surface of the cell. there is an important point that we have to
understand here., That is the lipid cell is hydrophilic on one end and hydrophobic on the other
end. Therefore, the hydrophobic ends of both cells join in the center of the lipid bilayer and the
hydrophilic ends expose themselves to the outer surface and the inner surface. Since they are
hydrophilic they can easily interact with the fluids they are exposed to unlike the hydrophobic
ends.
Therefore the correct option is D

What is simplicity and how does it bear on the acceptability of a sc.pdf
What is simplicity and how does it bear on the acceptability of a scientific hypothesis?
Solution
Simplicity - simpler means fewer assumptions. Consider Newtons mechanics and copernican
hypothesis . They both stand as examples of generality and simplicity. Newton with help of
previous general set of laws explained laws of motion for terrestial and heavenly bodies.
Copernicus explained the same observational data with simpler assumptions. The virtues are not
independent and in some cases it overlaps. In some cases generalisation will be simplification.
Simplicity is used for describing philosophical theories . In general if a hypothesis is more
simpler it can be confirmed . In some cases precision overlaps simplicity. The reality is part of
quine pervasive scientific realism. Quine quotes for simplicity. Quine also quotes that different
classes or groups can be clearly dealt only if is in simpler explanatory view and relative
simplicity of the system. Hence a scientific theory should not be generalised but should be in
simplified form..
What’s the difference between soluble and insoluble fiberWhy is f.pdf

molecules, similar to amylose?
What are some of the benefits of increasing fiber intake?
How does fiber confer these benefits?
What are some of the potential pitfalls of consuming excess fiber?
How does fiber confer these detriments?
What are the general recommendations for fiber intake?
We refer to some of our fibers as prebiotics. What does that term really mean? How does a
prebiotic aid gut health?
Solution
What’s the difference between soluble and insoluble fiber?
ANS: In short soluble fibres dissolve in water and insoluble fibres do not.
Soluble fibre makes our food more viscous when in a digestive tract. Soluble fibre traps food
components thus making them less absorbable. Insoluble fibre absorbs water for example how
dry sponge expands after soaking up water. Insoluble fibres are helpful in treating constipation.
Why is fiber indigestible? After all, isn’t cellulose just a string of glucose molecules, similar to
amylose?
ANS: What makes fibre indigestible is the lack of enzymes in humans to break down the
glycosidic bond in fibre.
What are some of the benefits of increasing fiber intake?
ANS: Benefits of fibre intake include:
gastrointestinal disorders
lowering cholesterol levels
lowering the risk of colon cancer
weight loss
How does fiber confer these benefits?
ANS: fibre has three mechanisms of action, which are bulking, viscosity and fermentation.
Fibres can use all three mechanisms or only one.
Bulking fibres absorb water and increase stool weight and regularity. Bulking fibres can be
minimally fermented or not fermented.
Viscous fibres thicken the content of the intestinal tract . They mix with water and form a
gelatinous mass. Depending on the type of viscous fibre, they are minimally, partially,
completely fermented or not fermented at all.
Fermentable fibres are used as food source for the microbes that exist on our large intestine.
What are some of the potential pitfalls of consuming excess fiber?
ANS: As fibre is not digested, too much fibre causes the digestive tracts to process it slowly, it
can lead to bloating, constipation, abdominal discomfort and gas. If constipation is prolonged, it
can lead to intestinal blockage. during intestinal blockage there can be malabsorption and
accumulations of toxins in the body..
What would you conclude if an inoculated plate had colonies betwe.pdf
What would you conclude if an inoculated plate had colonies between the streak lines?
What would you conclude if an inoculated plate had colonies between the streak lines?
Solution
It depends, if there is no growth or colony appearance on streak line and only it shows growth in
between streak line then it is certainly a contamination.If there are colonies on streak line and not
resemble with the streak culture then also it is a contamination but there can be a chance that
colony appears due to some fault in streaking procedure and the inoculum drops between the
streak line..

Solution
Question
Answer
Explanation
7) What is the sequence of events in a typical eukaryotic cell cycle
B)G1 to S to G2 to mitosis to cytokinesis
In most eukaryotic cells, the division cycle of is divided into four discrete phases: G1, S, G2 and
M, M phase is followed by cytokinesis.
8) In which stage below in Mitosis, centromeres/chromosomes are aligned at the equator phase
of the cell?
C) Metaphase
When the prometaphase ends and metaphase begins, the chromosomes will be seen aligned along
the cell equator.
9) Which one below is not the Cell cycle check point?
B)S—G2
G1/S checkpoints, G2/S checkpoint and M checkpoint, these are the three checkpoints found in
the cell cycle
10) The pairing of chromosomes along their lengths, which is essential for crossing over referred
to as
B)synapsis
During synapsis only you can see the pairing up of the homologous chromosomes side by side
during meiosis I. Here each homologue pairs along its entire length to facilitate crossing over.
11) Which of the following statements about crossing over is false?
B)Crossing over takes place between sister chromatids
The exchange of chromosome segments between non-sister chromatids is seen during crossing
over and this will occur during the production of gametes.
12) Chromosomes fail to separate during meiosis, leading to abnormal number of chromosomes
B)Non-disjunction
During cell division, failure of homologous chromosomes or sister chromatids to separate
properly is known as Nondisjunction. Monosomy (2n-1) or trisomy (2n+1) are the example for
this

The U.S. government subsidizes flood insurance because those who wan.pdf
The U.S. government subsidizes flood insurance because those who want to buy it live in the
flood plain and cannot get it at reasonable rates. What inefficiency does this create
Solution
As Hurricane Sandy continues to batter the Eastern seaboard of the U.S., one thing is for certain:
insurance companies will be ponying up for billions of dollars in property damage caused by
high winds. Last year’s Hurricane Irene cost insurance providers more than $4 billion in damage
claims, with flood-insurance payments totaling nearly $1.3 billion.
But what many Americans may not know is that this $1.3 billion was a bill footed by the federal
government, which underwrites the vast majority of flood insurance across the nation.
Historically, insurance companies have been wary of offering flood insurance to homeowners
because the risks associated with flood insurance are difficult to forecast, so any private
insurance that had been offered was prohibitively expensive for average homeowners.
But in the 1960s, frequent flooding of the Mississippi River was driving up the costs of federal
disaster-relief programs. In an effort to reduce these costs,Congress set up the National Flood
Insurance Program (NFIP) to provide flood insurance to the general public and promote effective
floodplain management. Under the program, homeowners in certain areas of the U.S. are
required to buy flood insurance, and communities that hope to benefit from the program have to
enforce city-planning regulations set out by FEMA, which manages NFIP.
(MORE: Banks Waive Fees for Residents in Path of Hurricane Sandy)
Though the program has been effective at making flood insurance widely available, a growing
chorus of critics from environmentalists to libertarians has been attacking it for encouraging
homeowners to build recklessly in areas that are prone to flooding. For instance, Ira Stoll wrote
yesterday in the New York Sun:
“Hurricane casualties are partly the result of unintended consequences of government actions:
without federal flood insurance, many fewer people would take the risk of living in low-lying
areas vulnerable to storm surges.”
There is evidence to support the view that the government is actually encouraging citizens to live
in areas most in danger of flood damage. According to a 2010 report issued by the Institute for
Policy Integrity, Congress has historically set the premium rate too low for flood insurance —
effectively subsidizing building in flood-prone areas at the expense of taxpayers at large. This
practice has helped drive the fund $19 billion in debt, caused mostly by the unusually severe
damage caused by Hurricane Katrina.
In addition, the report argued that the environmental effects of the federal government’s flood-
insurance policy may be more severe than the financial effects. According to the report:
“River basins and coastal zones provide natural purification of water and wastewater; erosion
control and weather mitigation; and habitat for fish and wildl.
The primary difference between deterministic models and probabilisti.pdf
Deterministic models provide certain solutions based on known parametric inputs, while probabilistic models account for uncertainty and provide a level of certainty to predict outcomes rather than exact solutions. Probabilistic models are preferable when inputs cannot be precisely known.
The Darwinian revolution challenged traditional views of a young Eart.pdf
The Darwinian revolution challenged traditional views of a young Earth inhabited by
unchanging species. What were the prevailing thoughts about the Earth and the organisms on it
prior to Darwin? What was Darwin\'s big idea? How does it differ from previous ideas
explaining the diversity of life on Earth? What is the \'Scala Naturae\', who advanced this
concept and why was it so widely accepted? What is \'Systema Naturae\', who advanced this
concept and why so accepted? Who are these people did we talk about them? How are their ideas
relevant to a conversation about evolution? Malthus, Linneaus, Hutton, Lyell, cuvier, Lamarck,
Aristotle, Darwin, Mendel, Wallace What did Lamarck propose as an explanation for how
organisms change over time? Explain how Lamarck\'s ideas are not supported by evidence?
Descent with modification by means of natural selection explains the adaptations of organisms
and the unity and diversity of life What did Darwin do that most influenced his worldview (what
is a worldview)? What were the critical observations Darwin made on his voyage of discovery?
What two main ideas did Darwin develop in the \"Origin of Species\"? What is natural
selection? (Look at the lecture powerpoints to answer the question) What are three main points
and important considerations regarding natural selection? What is an adaptation? What are the
two observations and two inferences that explain how natural selection leads to adaptive
evolution? What role did artificial selection play in the development of Darwin\'s logic for
natural selection? What does the theory of evolution suggest will happen when environments
favoring one adaptation change?
Solution
Ques-1: What were the prevailing thoughts about the young Earth and the organisms on it prior
to Darwin
The prevailing thoughts about the young Earth and the organisms on it prior to Darwin are
creatures were created by supernatural power & human are going to control these creatures and
populations are unchanging on the young Earth. Theory of evolution of “Darwin” has produced
specific impact on the imperialism and biblical view of origin of the species finally affected
contemporary philosophical views of religion & creation. These views have changed socio-
economical perspectives in the society about the culture finally changed the “religious views of
humans that “human race has evolved from God’s creation & God’s image”.
Ques-2: What was Darwin\'s big idea?
Answer:
Darwin theory of evolution is completely based on genetic variations and natural selection
operating on the species to acquire adaptations followed by unfit species are going to extinct.
However, here the extinction is not based on designer as it is due to nature. Nature selects
species, which are fit into it followed by elimination that is unfit in nature. It is different from
previous ideas of Earth species diversity, in which creation was completely relies upon myths
and God, the “religious views of humans that “human race has evo.
The average length of crocodiles in a swamp is 13 feet. If the lengt.pdf
The average length of crocodiles in a swamp is 13 feet. If the lengths are normally distributed
with a standard deviation of 2.2 feet, find the proportion of crocodiles more than 14.7 feet long.
Round your answer to two decimal places
Solution
Normal Distribution
Mean ( u ) =13
Standard Deviation ( sd )=2.2
Normal Distribution = Z= X- u / sd ~ N(0,1)
P(X > 14.7) = (14.7-13)/2.2
= 1.7/2.2 = 0.7727
= P ( Z >0.773) From Standard Normal Table
= 0.2198.

a case study on additive manufacturingSolutionHydrauilc block .pdf
- 1. a case study on additive manufacturing Solution Hydrauilc block manifold redesigned for additive manufacturing Additive manufacturing (AM) is highly suited for the design and manufacture of manifolds due to its ability to build internal features and passageways. Renishaw has collaborated with a customer to redesign their current hydraulic block manifold with additive manufacturing in mind. The main goal of the project was to reduce the mass of the component whilst retaining its robustness. Due to the increased design freedom associated with additive manufacturing, an opportunity to increase the efficiency of the flow paths was also identified.
