what are the basic methods to isolate nucleic acids? Solution The basic methods used in DNA precipitation are, 1). DNA precipitation 2). Phenol-chloroform extraction During DNA extraction procedure, the DNA clumps out because it is not soluble in ethanol. DNA is soluble in water, but the sodium ions present in the extraction media neutralizes the negatively charged phosphate ions. Now, the DNA becomes less soluble and form aggregates or clump together upon the addition of ethanol. The yield increases with using cold ethanol because the DNA is even less soluble in cold ethanol..

Acronym for system development life cycle. SDLC is the process of developing information
systems through investigation, analysis, design, implementation and maintenance. SDLC is also
known asinformation systems development or application development. SDLC is a systems
approach to problem solving and is made up of several phases, each comprised of multiple steps:
The software concept - identifies and defines a need for the new system
A requirements analysis - analyzes the information needs of the end users
The architectural design - creates a blueprint for the design with the necessary specifications for
the hardware, software, people and data resources
Coding and debugging - creates and programs the final system
System testing - evaluates the system\'s actual functionality in relation to expected or intended
functionality.
Sorting Out SDLC Terminology
We’ve probably all seen the job postings with a “required skills” line item that reads something
like the following:
Must be expert in a variety of software development methodologies including SDLC, RUP, XP,
PMP, Agile, Waterfall, Spiral, SEI, PMI, CMMI, PIMBOC, and Scrum.
To which, you might reply, “What are they talking about?”
Clearly, there are people in HR and recruiting (and I know some in development) who are
confused about software development methodologies, their names, acronyms, meanings, and
relationships to one another. Let’s try to sort this out a bit.
Untangling the terminology
To begin, many of the terms listed above are not SDLCs. The term SDLC is an acronym that
stands for Software Development Life Cycle (as well as System Design Life Cycle, System
Development Life Cycle and Synchronous Data Link Control). SDLC is used as a generic
umbrella term for any number of software development methodologies.
SDLC by itself is not a methodology. When the term SDLC shows up in a list of methodologies,
it is a clear indicator that the person who wrote this is confused about what it really means.
The internet American Heritage dictionary gives us the following definition for methodology:
-A body of practices, procedures, and rules used by those who work in a discipline or engage in
an inquiry; a set of working methods: the methodology of genetic studies; a poll marred by faulty
methodology.
Some of the SDLCs listed above do not claim to be methodologies. To be more accurate, an
SDLC is anapproach to managing a software deve.

describe how the composition of the population changed Solution.pdf
describe how the composition of the population changed ?
Solution
The major reason for population changes, whether in an individual country or for the whole
world, is the change in birth and death rates. The birth rate is the number of live babies born in a
year for every 1000 people in the total population. Death rates are number of people dying per
1000 people. When birth rates are higher than death rates the population of an area will increase.
migration are the number of people migrate from one country or society to the other. BIRTH
RATE: when babies are born, it results in a population change, The fertility rate in a country
refers simply to the number of children born. This is different from the fecundity rate, which is
the number of children who could be born in a given society. In other words, fecundity is the
biological capacity of humans to produce children.The fecundity rate is greater than the fertility
rate in most cases. Birth rates vary by society for a number of reasons, including personal choice
and social and political factors. Factors such as poverty level, access to contraception, maternal
and infant care, and availability of nutrition all impact the birth rate in a society. DEATH RATE:
As the growth rates increases the death rate also increases. when babies are born, when members
of a society die it changes the population. butthis is refered as the mortality rate, which is simply
the number of deaths that occur in a society. This is usually calculated by looking at the number
of deaths per 1,000 individuals. In the United States, for example, the death rate is 8/1000
people. Just like birth rate, the death rate in a country depends on things such as availability of
quality medical care, disease, war, or famine. MORTALITY: The most important factor that
accounts for a change in population is migration. Generally migration refers to movement; it\'s
the flow or circulation of people in societies. There are two kinds of migration: emigration and
immigration. Emigration means to leave one\'s own country for another. Immigration means to
enter into a country other than one\'s own. Both of these process impact population change. The
composition also depends upon age structure. Age structure varies according to age distribution
of an individual, therefore the population size is expected to double or even triple before
stabilizing for many developing countries with fairly large populations and large numbers of
people under age 15..

Veblen, \"Why is Economics Not an Evolutionary Science\"
consisting 500 words, my homework due is today at 10:00 p.m.
Solution
\"Why is Economics Not an Evolutionary Science\" was written in1898. According to veblin the
only rational approach is to assume economies evolve because he argued that we can describe
the economy and have not any effective theory of change and development. Veblen classes the
assumption that that economies ‘normally’ tend towards equilibrium—as no more rational that
the spiritually-based notion that there is a final cause or teleological pull towards some natural
outcome due to natural law; that is, “a preconception regarding the ends to which, in the nature
of things, all things tend (P.392) .Veblen is insistent, however, that we cannot understand
economics without paying attention to human learning.Veblen does not see evolution as
something that happens primarily to individuals but as a collective change to societies, and
collections of institutions.According to him evolution is a dispassionate cumulative
causation..Most of the people including me likes this paper because it reminds us that most of
what we think has been thought before, just not acted upon; because it seems to sow the seeds for
much of what followed in terms of complexity and evolutionary economics.Veblen in his paper
has sheer command of language and he touches on most of the challenges that economist ever
since have raised about.

1.S. cerevisiae can switch mating types. Which of the following stat.pdf
1.S. cerevisiae can switch mating types. Which of the following statements correctly summarizes
where the information comes from for it to do this?
Solution
Saccharomyces cerevisiae occurs in two forms, the haploid and diploid. The haploid cells
undergo mitosis, which die under the conditions of higher stress. The preferential form of the
yeast is diploid, which undergoes growth by mitosis.
In cerevisiae, the cells of opposite mating type are present in the same ascus. They are produced
by a single meiosis and mate with each other. Means, the organism can switch mating types. The
mating locus contains two-mating loci in inactive state, which provide the information to replace
the inactive copy at the mating locus with the active copy..
You produce an interference pattern by projecting a blue laser with .pdf
You produce an interference pattern by projecting a blue laser with a wavelength of 405 nm
through the double slits you used in the today’s experiment. The lens is placed 51.2 cm from the
screen. What is the distance between two adjacent bright spots? Show all work.
Solution
Let\'s assume separation between the slits is, d = 0.10mm = 10-4 m
Wavelength of light, Lembda = 405 x 10-9 m
Distance of screen, D = 51.2 x 10-2 m
Distance between two adjacent bright spots = D x Lemda / d
= [51.2 x 10-2 x 405 x 10-9 ] / 10-4 = 2.07 mm.

You are working with the file directory of a Windows XP computer from the command line, and
you use the md command to create a new directory in your My Documents directory. What
command switch can you issue to confirm that the new directory was created?
A. Just use the dir command to view all of the directories and files in the My Documents and
look for the name of directory you just created
B. dir /new
C. dir /bn
D. dir /ad
Solution
D. Using the dir command with the /ad switch will show just directories in the current working
directory, such as My Documents, making it easier to spot the newly created directory. If the list
is very long, you can also add the /p switch to pause and scroll through each screen, such as
dir/ad /p..

You deposit $1,000 in a fund earning 5.75%. How long will it take to double your money?
Solution
Let us suppose that it will take n years to get double. Hence,
1000(1+0.0575)^n=2000
or,log1000+nlog(1.0575)=log2000
or, 3+0.024280n=3.30102
or, n=0.301029/0.024280=12.3
Hence it will take almost 12.3years to get double.

Below are transactions for February 2018:
Record Journal Entries for following transactions:
02/01
Included in WWC’s February 1 Accounts Receivable balance is a $1,500 account due from Kit
Kat, a WWC customer. Kit Kat is having cash flow problems and cannot pay its balance at this
time. WWC arranges with Kit Kat to convert the $1,500 balance to a note, and Kit Kat signs a 6-
month note, at 9% annual interest. The principal and all interest will be due and payable to
WWC on August 1, 2012.
02/02
WWC paid a $900 insurance premium covering the month of February. The amount paid is
recorded directly as an expense.
02/05
An additional 150 units of inventory are purchased on account by WWC for $11,250 – terms
2/15, n30.
02/05
WWC paid Federal Express $450 to have the 150 units of inventory delivered overnight.
Delivery occurred on 02/06. (Hint--Recall company uses perpetual inventory system, record
transportation fees as part of inventory costs—debit to inventory)
02/10
Sales of 120 units of inventory occurred during the period of 02/07 – 02/10. The sales terms are
2/10, net 30. (Hint --Recall company follows FIFO. What are the COGS of 120 sold units?)
02/15
The 40 units that were paid for in advance and recorded in January are delivered to the customer.
(Hint --Recall WWC follows FIFO. What are the COGS of 40 sold units?)
02/15
10 units of the inventory that had been sold on 2/10 are returned to WWC. The units are not
damaged and can be resold. Therefore, they are returned to inventory. Assume the units returned
are from the 2/05 purchase.

Which of the following statements is true about the interaction of e.pdf
Which of the following statements is true about the interaction of electromagnetic radiation with
matter?
1) Photoelectric absorption involves the interaction of a photon with the nucleus of an atom.
2) Rayleigh scattering involves an inelastic collision of a photon with an outer-shell electron with
negligible binding energy, after which that electron is ejected from the atom.
3) The main phenomena associated with X-ray imaging are Rayleigh scattering at low photon
energies and pair production at high photon energies.
4) The main phenomena associated with X-ray imaging are photoelectric absorption at low
photon energies and Compton scattering at high photon energies.
5)None of these statements are true.
Please explain why.
Solution
1) The statement is true.
The photons with atom particles are by chance, a given photon has a finite probability of passing
completely through the medium it is traversing. The probability that a photon will pass
completely through a medium depends on numerous factors including the photon’s energy and
the medium’s composition and thickness. The more densely packed a medium’s atoms, the more
likely the photon will encounter an atomic particle.
2)False
The photons doest not excite the atom when it interacts with the one or more bounded electrons.
The energy is same at the end of the process, that is energy of photon is equal to the interacting
atom. Therefore, it is elastic scattering.
3)
This statement is true.
Rayliegh scattering involves in deflection of the incoming particle, but not absorption.hence it
occurs for low photon energies. Whereas the pair productionrequires very high energy as the
photon interacts with the electron or nucleaus and forms postiron electron pairs. The photon must
have atleast 1.022 MeV energy to interact.
4)
The statement is false.
As the photoelectric absorption involves in absorption of photons by atoms which have
considerably high energy as discussed in first point.
So statements 1 and 3 are true..

What is the use of discrete gates with the use of an FPGA.Soluti.pdf
What is the use of discrete gates with the use of an FPGA.
Solution
A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a
customer or a designer after manufacturing – hence \"field-programmable\". The FPGA
configuration is generally specified using a hardware description language(HDL), similar to that
used for an application-specific integrated circuit (ASIC). (Circuit diagrams were previously
used to specify the configuration, as they were for ASICs, but this is increasingly rare.)
FPGAs contain an array of programmable logic blocks, and a hierarchy of reconfigurable
interconnects that allow the blocks to be \"wired together\", like many logic gates that can be
inter-wired in different configurations. Logic blocks can be configured to perform
complexcombinational functions, or merely simple logic gates like AND and XOR. In most
FPGAs, logic blocks also include memory elements, which may be simple flip-flops or more
complete blocks of memory.

2 a. RNA polymerase II that is actively transcribing a gene (activel.pdf
2 a. RNA polymerase II that is actively transcribing a gene (actively progressing along the DNA
polymerizing an RNA molecule) is phosphorylated. Researchers evaluated the abundance (the
frequency of occupancy) of RNA PolII at difference positions along a gene, and correlated that
with the introns and exons of the gene. The figure represents a portion of one gene that is
transcribed from left to right. The X axis corresponds to position along the DNA, and the boxes
below the figure illustrate where the exons are (with the lines between them representing the
introns). The Y axis represents the relative frequency of occupancy (relative abundance of active
RNA PolII using two different measures [pSer2 and pSer5]). A high the value on this axis means
that, when they sample whether RNA polII is present at the given position, they find the enzyme
present more frequently than at positions where the value is low.
a. With respect to intron/exon boundaries, what positions does the (transcribing) RNA PolII
occupy most?
b. How do you interpret this observation (i.e., does it say anything about how fast or how slow
RNA PolII is moving at different positions across the gene)? Does it suggest anything about the
relationship between transcription and splicing?
2b. You characterize the sequence of a full-length cDNA and the corresponding genomic DNA
for a particular intron-containing gene from mouse cells. When you align them to each other
using a computer program, the exons of the cDNA align perfectly in some regions with pieces of
the genomic DNA, whereas other exons appear to have a small number of specific nucleotide
differences compared to the genomic DNA. Assume this genomic DNA and cDNA come from
the same individual, and there are no sequencing mistakes. What might account for these
differences? ,241 132 15 98 459605 719M850 1341/1417 Ratio pser relative to RNAPI
Solution
2a RNA polymerase II at first recognizes and binds to the promoter DNA forming a state termed
as the closed complex. Following this the DNA surrounding the transcription start site is
unwound and the template strand is positioned in the Polymerase active site, forming the open
complex. Transcription initiation then commences, initially producing short RNA products.
b Alternative splicing is a crucial mechanism for gene regulation and for generating genomic
diversity. Recent studies indicate that the expression of nearly 95% of human multi-exon genes
involves alternative splicing. In metazoans, alternative splicing plays an important role in
generating different protein products that function in diverse cellular processes including cell
growth, differentiation and death.
Splicing is carried out by the spliceosome. A massive structure in which five small nuclear
ribonucleoprotein particles (snRNPs) and a large number of auxiliary proteins cooperate to
accurately recognize the splice sites and catalyse the two steps of the splicing reaction.

the reason of going infrastructure underground
Solution
Land and Location:
Nature has given us limited resourses and the world we are living is three dimensional.
Most of the mankind from their evolution is using this world in two dimensions only. Population
is increasing day by day but the land we are living is not increasing. So, there is a necessity of
using the third dimension i.e. up or down.
If we are going to construct a metro in cities like Delhi (capital of india), It should be
underground. Beacuse, comparing with area available in delhi, the populatin is too high. Delhi
has too much populaiton density and lots of buildings on the land of delhi and literally no place
available for new construction and it is impossible to construct a metro over the land. So, they
constructed most of the metro in delhi in underground.
Enviromental:
Underground space offers natural protection to whatever is placed underground.
If underground release any contaminants, surface environment is safe from them.
Topographical:
If we are going to construct a road or rail track in a hill area, it will be difficult and the journy
above hills and mountains is not safe always. In that kind of places , underground tunnels are

1.S. cerevisiae can switch mating types. Which of the following stat.pdf
1.S. cerevisiae can switch mating types. Which of the following statements correctly summarizes
where the information comes from for it to do this?
Solution
Saccharomyces cerevisiae occurs in two forms, the haploid and diploid. The haploid cells
undergo mitosis, which die under the conditions of higher stress. The preferential form of the
yeast is diploid, which undergoes growth by mitosis.
In cerevisiae, the cells of opposite mating type are present in the same ascus. They are produced
by a single meiosis and mate with each other. Means, the organism can switch mating types. The
mating locus contains two-mating loci in inactive state, which provide the information to replace
the inactive copy at the mating locus with the active copy..

You produce an interference pattern by projecting a blue laser with a wavelength of 405 nm
through the double slits you used in the today’s experiment. The lens is placed 51.2 cm from the
screen. What is the distance between two adjacent bright spots? Show all work.
Solution
Let\'s assume separation between the slits is, d = 0.10mm = 10-4 m
Wavelength of light, Lembda = 405 x 10-9 m
Distance of screen, D = 51.2 x 10-2 m
Distance between two adjacent bright spots = D x Lemda / d
= [51.2 x 10-2 x 405 x 10-9 ] / 10-4 = 2.07 mm.

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

what are the basic methods to isolate nucleic acidsSolutionTh.pdf
- 1. what are the basic methods to isolate nucleic acids? Solution The basic methods used in DNA precipitation are, 1). DNA precipitation 2). Phenol-chloroform extraction During DNA extraction procedure, the DNA clumps out because it is not soluble in ethanol. DNA is soluble in water, but the sodium ions present in the extraction media neutralizes the negatively charged phosphate ions. Now, the DNA becomes less soluble and form aggregates or clump together upon the addition of ethanol. The yield increases with using cold ethanol because the DNA is even less soluble in cold ethanol.
