Describe the difference between descriptive and inferential statistics. Solution Descriptive and inferential statistics are the two main branches of the science of statistics. Inferential statistics use a random sample of data taken from a population to describe and make inferences about the population. Inferential statistics are valuable when it is not convenient or possible to examine each member of an entire population. Descriptive statistics provide a concise summary of data. You can summarize data numerically or graphically..

What is frictionSolutionThe force that resist relative motion .pdf
What is friction
Solution
The force that resist relative motion of solid surfaces ,layers of fluid and material elements that
slides against each other is called friction .there are many times of friction:
dry friction-it resists the relative motion between solid surfaces that appears in contact with each
other.it is ssubdivided into two types: static friction that is between surfaces that are non moving
and kinectic friction that is between moving surfaces
Fluid friction-it describes friction between viscous fluid layers that makes movement relative to
each other
lubricated friction-the seperstion between solid surfaces is made by a fluid lubricant.
skin friction-the force that resists fluid motion across body surface.
rolling friction-it resists the relative motion of a rollong object.it is a combination of various
frictional force types at wheel\'s point of contact and the surface..
What happens to the nominal exchange rate when the USs rate increa.pdf
If the US nominal exchange rate increases and prices rise faster in the US than abroad, the US currency will nominally appreciate. This means fewer US dollars are needed to purchase a unit of foreign currency. As a result, imports to the US will become costlier while exports out of the US will become more attractive.

We have not seen any humming birds in this forest today
We have not seen any humming birds in this forest after observing for two years
Humming birds are not usually found in forests
Therefore there are probably no humming birds in this forest.
This argument is what ?
Solution
Humming birds found in north america, south america and central america. they are mostly
found in areas where abundant insects, plants with nectars, water and safe places for building
nests are present.
Humming birds mostly tends to live in bushes, trees and shrubs that provide enough protection
for shrubs. Humming birds do not tend to live in bird houses and structures provided by home
owners seeking to encourage the birds to visit. Many humming birds love the habitat of wooded
forest areas that have lots of flowers.
Humming birds are wont be able to found to survival in cooler areas. However they are found in
coastal areas, desert areas, forest areas and meadows. Humming birds tend to live alone and will
put up with other humming birds where plenty of food is available..

The positron decay of ^15 O goes directly to the ground state of ^15 .pdf
The positron decay of ^15 O goes directly to the ground state of ^15 N; no excited states of ^15
N are populated and no gamma rays follow beta decay. Yet a source of ^15 O is found to emit
gamma rays of about 0.5 MeV. Explain the origin of these rays.
Solution
gamma rays almost always accompanies other radioactive emmissions because it represents
energy loss when the remaining nucleons reorganise into more stable arrangements. thus here in
this problem the origin of gamma rays arise due to mass defect as per Einesteins theory of
relativity..
The disease bullous pemphigoid results in the destruction of protein.pdf
The disease bullous pemphigoid results in the destruction of proteins within the basement
membrane that hold the epidermis and dermis together. How would this likely affect the
epidermis?
Solution
Bullous pemphigoid is an autoimmune disease.
Due to the nature of the disease, the cohesion between the dermis and the epidermis is destroyed.
The epidermis tends to separate from the dermis and in the intervening space, body fluids fill up,
giving the appearance of lesions. The colour and size of the lesions vary. In some patients they
may cover large parts of the anatomy. The lesions when disturbed burst, spilling their contents.
This may further lead to secondary infections and provide a pathway for pathogens to enter the
body..

QUESTION 8 1.00000 P Financial intermediaries are different from inve.pdf
QUESTION 8 1.00000 P Financial intermediaries are different from investment banking houses
in that financial intermediaries issue their securities to obtain funds from savers and then use the
fund to purchase other business\'s securities, while investment banking houses do not issue their
securities. Instead, savers\' money merely passes through investment banking houses. e True
False
Solution
Answer: This statement is false.
Financial Intermediaries- These are the financial institutions that work as mediator between two
parties, they include commercial banks, investment bank, mutual funds, NBFCs, pension fund
etc. These intermediaries channel funds from those who have it in excess to those who need
funds.
Investment banking- It is special branch of banking that provides many services like
underwriting, broking, portfolio management, M&A, restructuring, consultancy etc. These help
the new firms to raise capital from the market and go public by issuing shares to the general
public..

Post your response to the following focus questions:
Describe a sole proprietorship and discuss its advantages and disadvantages.
Describe a partnership and discuss its advantages and disadvantages.
Describe a corporation and discuss its advantages and disadvantages.
Describe an S corporation and discuss its advantages and disadvantages.
Solution
Broadly speaking for conducting any type of Business activity we require to have a Business
entity. If the Business entity is owned and operated and managed by a single paerson then such
Business entity is called a sole Proprietorship. It is most simple and subjected to least terms &
conditions governing the business activities. The main disadvantages includes personal liability
of the owner/ propreitor, which is unlimited. A single person being at the helm of affairs poses
limitations on the development and growth of the business. Propreitorship has its death with the
death of the owner.
A Partnership as the word suggest is that form of Business entity which is owned by two or more
persons and formed under an agreement signed by all owners for some common purpose/ goal
and or objectives. A partnership firm is more complicated than the sole propreitorships, two or
more persons as owners may give advatages of sharing resources, knowledge, skills which are
essential for setting up of businesses of sizes unmanageable by a single person. Pooling diversity
of partners helps in the development and growth of the Business entity. Like sole propreitorship,
the partners under partnerships may be subjected to unlimited liabilities under or arising out of
the business activities of the Partnership firm. There are additional set of rules & regulations
under the law of the land governing the partnership firms.
The third and the most prefered form of business entity is an incorporated firm called corporation
and or company. A corporation/ company is different from its owners. This form of business
entity draws difference between the owner and management of the business entity. Unlike the
earlier set ups of Sole Propreitor and Partnership, the business activies are conducted neither by
sole owner nor by partners but managers who are considered to be having different identity than
the business entity which is also considered as a legal person. A corporation can be sued and it
can also sue others in the court of law.A corporation comes into existence with its incorporation
documents such as Memorandum of Understanding, Articles of Associations, Delegation of
Powers etc. These documents required for giving birth to the corporation varies from state to
state, nation to nation, lews of the land under whose jurisdiction it falls. The main advantage of a
corporation is to give limited liability to its owners who are called share holders and its business
activities are conducted by the professionals having required qualifications and skills. Just like its
birth, its death is not related to that of its share holders (owners).

Linear Algebra
Hello. I need help with my practice final. I am not trying to copy. I want to see If I am doing it
right So please help. Thank you very much!
Here\'s the problem Let V and W be (finite-dimensional) vector spaces. In fact, unless otherwise
stated in one of the problems or definitions below you may assume that dim V n and dimW m.
Also, unless otherwise stated, let T V W be a linear transformation. Definitions and Basic
Results 1. The kernel of T, written ker T, is the set of vectors UE v such that T(i) 30w. 2. The
range of T, written range T is the set of vectors i e W such that T(i) if for some i E V. 3. T is
injective means that whenever i E V then T(ii) T(i2) if and only if ii J v2 4. T is surjective means
range T W 5. T is bijective if and only if it is both injective and surjective. 6. T is called a linear
operator if V W 7. Let T be a linear operator in V and let u be subspace of V. u is said to be
invariant under T if T(ii) Eu for every i Eu 8. Let u and u be aces of V (a) The sum of these
subspaces, written uitu2, is the set of vectors i EV that can be written as a sum of vectors ii ii2
where ii E uh and ii2 Eu2. (b) V is said to be a direct sum of u and up, written V Juh Du2, if and
only if for every if E V there exists a unique pair of vectors iii E ui and ii2 Eur such that if ii ii2.
Examples R2 z-axis) (y-axis). Ra (ary-plane) axis A) span span Fact V u if and only if v un +uo
and un nu
Solution
if T is injective then there should be a map of v in w for every v belonging to V and w belonging
to W. Consider the basis of W as all elements are maped then the dim of W should be at least
equal to the dimension of V as linear transformation map each basis element of V to some basis
element in W
If T is surjective then same argument above applies to just opposite because now mapping covers
all the elements of W.
if T is bijective then it is both injective and surjective .So now only equality can hold hence
dim(V) = dim(W).
Many nations, including the US, already maintain a national DNA data.pdf
Many nations, including the US, already maintain a national DNA database of samples collected
during criminal investigations, but there are often questions of whether such databases should be
expanded to include more individuals, or whether their use is ethical at all. What arguments can
you make for and against \"banking\" DNA profiles (i.e. \"genetic fingerprints\" based on STRs,
not necessarily full genome sequences) in a database? Do you believe such databases are ethical
or an invasion of privacy? Should it be mandatory for some or all individuals? What restrictions
would you place on it?
Solution
ARGUMENTS FOR:
A DNA database covering the entire populace and each guest to the UK, as upheld by Lord
Justice Sedley, would spare huge measures of police time and help clear up violations quicker.
The individuals who do nothing incorrectly have nothing to fear and ought to be consoled.
The present framework - the DNA of each one of those captured for recordable offenses, liable
or not, is held - is specific and wasteful.
Current practice is uncalled for: ethnic minorities and youngsters are over-spoken to, making
hatred and hostile to police feeling. Two-in-five dark men have their DNA on record, as against
less than one-in-ten whites.
The world has changed: universal versatility implies that potential fear based oppressors can
travel every which way, frequently on false papers.
ARUGMENTS AGAINST:
It would be a definitive stride making progress toward a \'The government\' state: Britain would
turn into \'a country of suspects.
Whatever the utility of DNA tests, there is something inalienably exasperating about entering
each infant on a database during childbirth.
A national DNA bank would be enormously costly and bureaucratic.
It is harming to the picture of the UK - \'Welcome to Britain: now give a mouth swab\'.
DNA data could be mishandled by degenerate police and others wrongfully passing data to
unapproved individuals.
PRIVACY ISSUE:
Individual data is now held by gatherings in the private division, if individuals can believe the
private part then they ought to have the capacity to confide in the Government.
In 2010, the UK Government promised to roll out improvements to the period of time DNA tests
are kept in the UK National DNA Database. These were incorporated into the 2012 Protection of
Freedoms Act. These progressions guarantee that the DNA (and fingerprints) of people captured
yet not indicted an offense is held for a most extreme of 5 years.
The DNA Identification Act of 1994 unequivocally permits database records to be made
accessible for innovative work the length of all actually identifiable data is expelled.
It need not be mandatory for all the individuals but as a matter of national security it should be
taken into consideration.Some restrictions like the privacy issue and the information of that
should not be accessed to everyone instead the government should be in a position to give the
required information neccesary and sho.

UNIVAC with IBM:
IBM got in 1951 when it lost the Census Bureau business to UNIVAC. That setback reenergized
IBM, which had dominated pre-computer data processing.
Determined to meet the challenge—and eyeing data processing needs in the Korean War—IBM
designed its 701 computer in just one year. After that, a flurry of new models eroded UNIVAC’s
lead.
the best mechanism is

How are nuclear pores and porins in the membrane differentSolut.pdf
How are nuclear pores and porins in the membrane different?
Solution
Nuclear pores: are large protein complexes that cross the nuclear envelope, which is the double
membrane surrounding the eukaryotic cell nucleus. There are about an average of 2000 nuclear
pore complexes (NPCs), in the nuclear envelope of a vertebrate cell, but it varies depending on
cell type and the stage in the life cycle.[1] The proteins that make up the nuclear pore complex
are known as nucleoporins. About half of the nucleoporins typically contain solenoid protein
domains—either an alpha solenoid or a beta-propeller fold, or in some cases both as separate
structural domains. Each NPC contains at least 456 individual protein molecules and is
composed of 30 distinct proteins (nucleoporins).
NuclearPorins:nucleoporins are a family of proteins which are the constituent building blocks of
the nuclear pore complex (NPC).[1] The nuclear pore complex is a massive structure that
extends across the nuclear envelope, forming a gateway that regulates the flow of
macromolecules between the cell nucleus and the cytoplasm. Nuclear pores in turn allow the
transport of water-soluble molecules across the nuclear envelope. Nucleoporins, a family of
around 30 proteins, are the main components of the nuclear pore complex in eukaryotic cells.
Nucleoporin 62 is the most abundant member of this family.[2] Nucleoporins are able to
transport molecules across the nuclear envelope at a very high rate. A single NPC is able to
transport 60,000 protein molecules across the nuclear envelope every minute..
How many allotropic forms does uranium have Discuss the effect of a.pdf
How many allotropic forms does uranium have? Discuss the effect of allotropic transformation
on the properties of uranium.
Solution
Metallurgically, uranium metal may exist in three allotropic forms: orthorhombic(alpha),
tetragonal (beta), or body-centered cubic (gamma), and may be alloyed with other metals to alter
its structural and physical properties to suit the application.
Uranium undergoes allotropic transformations around 665 and 770°C.When room temperature
alpha uranium is heated melted it undergoes three distinct transformations, but the
transformations which occur while cooling are important.when the liquid metal solidifies.Slow
cooling results in soft metal, while rapid cooling inreases its hardness.
At room temperature uranium exists in alpha phase which is semi plastic and corrosive. When
heated to beta phase it becomes brittle and hard. The gamma phase is most suited for working as
it can be forged, drawn and extruded..

Explain homologous recombination between human X and Y chromosomes..pdf
Explain homologous recombination between human X and Y chromosomes.
Solution
X and Y chromosomes homology:
The X chromosome is a large sub metacentric chromosome, which contains many genes on it.
Among these genes most are unrelated to sex.
The Y chromosome is a small acrocentric chromosome. In this chromosome 83 active genes are
present, in which most are related to sex determination and spermatogenesis.
The gene of Y chromosome is a pseudogene. It clearly explains the common evolutionary origin.
Homologous recombination between human x and y chromosomes:
In human X and Y chromosomes several homological sequences of regions are identified.
Generally the chromosomes X and Y are paired during in meiosis and undergo crossing over.
these regions are called pseudoautosomal regions., PAR1 and PAR2.
PAR1 crossover is very important in male meiosis. in this chromosomes proper segregation was
occur.
where they exchange only DNA within the pseudoautosomal region at the distal short arms of
both chromosomes.
However, it has been suggested that aberrant recombination involving other segments of high
homology could be responsible for the production of X/Y translocations..

By looking at the skeleton of a python, a boa contricor and a legles.pdf
The document discusses evidence that snakes like pythons and boa constrictors evolved from four-legged ancestors. Fossil evidence suggests snakes evolved from burrowing lizards that had legs which became smaller over time as burrowing favored more streamlined bodies. While the ancestor is disputed, the evidence indicates proto-snakes possessed legs that later disappeared as legs were more hindering underground.

The positron decay of ^15 O goes directly to the ground state of ^15 .pdf
The positron decay of ^15 O goes directly to the ground state of ^15 N; no excited states of ^15
N are populated and no gamma rays follow beta decay. Yet a source of ^15 O is found to emit
gamma rays of about 0.5 MeV. Explain the origin of these rays.
Solution
gamma rays almost always accompanies other radioactive emmissions because it represents
energy loss when the remaining nucleons reorganise into more stable arrangements. thus here in
this problem the origin of gamma rays arise due to mass defect as per Einesteins theory of

The disease bullous pemphigoid results in the destruction of protein.pdf
The disease bullous pemphigoid results in the destruction of proteins within the basement
membrane that hold the epidermis and dermis together. How would this likely affect the
epidermis?
Solution
Bullous pemphigoid is an autoimmune disease.
Due to the nature of the disease, the cohesion between the dermis and the epidermis is destroyed.
The epidermis tends to separate from the dermis and in the intervening space, body fluids fill up,
giving the appearance of lesions. The colour and size of the lesions vary. In some patients they
may cover large parts of the anatomy. The lesions when disturbed burst, spilling their contents.
This may further lead to secondary infections and provide a pathway for pathogens to enter the
body..

QUESTION 8 1.00000 P Financial intermediaries are different from inve.pdf
QUESTION 8 1.00000 P Financial intermediaries are different from investment banking houses
in that financial intermediaries issue their securities to obtain funds from savers and then use the
fund to purchase other business\'s securities, while investment banking houses do not issue their
securities. Instead, savers\' money merely passes through investment banking houses. e True
False
Solution
Answer: This statement is false.
Financial Intermediaries- These are the financial institutions that work as mediator between two
parties, they include commercial banks, investment bank, mutual funds, NBFCs, pension fund
etc. These intermediaries channel funds from those who have it in excess to those who need
funds.
Investment banking- It is special branch of banking that provides many services like
underwriting, broking, portfolio management, M&A, restructuring, consultancy etc. These help

Post your response to the following focus questions:
Describe a sole proprietorship and discuss its advantages and disadvantages.
Describe a partnership and discuss its advantages and disadvantages.
Describe a corporation and discuss its advantages and disadvantages.
Describe an S corporation and discuss its advantages and disadvantages.
Solution
Broadly speaking for conducting any type of Business activity we require to have a Business
entity. If the Business entity is owned and operated and managed by a single paerson then such
Business entity is called a sole Proprietorship. It is most simple and subjected to least terms &
conditions governing the business activities. The main disadvantages includes personal liability
of the owner/ propreitor, which is unlimited. A single person being at the helm of affairs poses
limitations on the development and growth of the business. Propreitorship has its death with the
death of the owner.
A Partnership as the word suggest is that form of Business entity which is owned by two or more
persons and formed under an agreement signed by all owners for some common purpose/ goal
and or objectives. A partnership firm is more complicated than the sole propreitorships, two or
more persons as owners may give advatages of sharing resources, knowledge, skills which are
essential for setting up of businesses of sizes unmanageable by a single person. Pooling diversity
of partners helps in the development and growth of the Business entity. Like sole propreitorship,
the partners under partnerships may be subjected to unlimited liabilities under or arising out of
the business activities of the Partnership firm. There are additional set of rules & regulations
under the law of the land governing the partnership firms.
The third and the most prefered form of business entity is an incorporated firm called corporation
and or company. A corporation/ company is different from its owners. This form of business
entity draws difference between the owner and management of the business entity. Unlike the
earlier set ups of Sole Propreitor and Partnership, the business activies are conducted neither by
sole owner nor by partners but managers who are considered to be having different identity than
the business entity which is also considered as a legal person. A corporation can be sued and it
can also sue others in the court of law.A corporation comes into existence with its incorporation
documents such as Memorandum of Understanding, Articles of Associations, Delegation of
Powers etc. These documents required for giving birth to the corporation varies from state to
state, nation to nation, lews of the land under whose jurisdiction it falls. The main advantage of a
corporation is to give limited liability to its owners who are called share holders and its business
activities are conducted by the professionals having required qualifications and skills. Just like its
birth, its death is not related to that of its share holders (owners).

Here\'s the problem Let V and W be (finite-dimensional) vector spaces. In fact, unless otherwise
stated in one of the problems or definitions below you may assume that dim V n and dimW m.
Also, unless otherwise stated, let T V W be a linear transformation. Definitions and Basic
Results 1. The kernel of T, written ker T, is the set of vectors UE v such that T(i) 30w. 2. The
range of T, written range T is the set of vectors i e W such that T(i) if for some i E V. 3. T is
injective means that whenever i E V then T(ii) T(i2) if and only if ii J v2 4. T is surjective means

Solution
if T is injective then there should be a map of v in w for every v belonging to V and w belonging
to W. Consider the basis of W as all elements are maped then the dim of W should be at least
equal to the dimension of V as linear transformation map each basis element of V to some basis
element in W
If T is surjective then same argument above applies to just opposite because now mapping covers
all the elements of W.
if T is bijective then it is both injective and surjective .So now only equality can hold hence
dim(V) = dim(W).
Many nations, including the US, already maintain a national DNA data.pdf
Many nations, including the US, already maintain a national DNA database of samples collected
during criminal investigations, but there are often questions of whether such databases should be
expanded to include more individuals, or whether their use is ethical at all. What arguments can
you make for and against \"banking\" DNA profiles (i.e. \"genetic fingerprints\" based on STRs,
not necessarily full genome sequences) in a database? Do you believe such databases are ethical
or an invasion of privacy? Should it be mandatory for some or all individuals? What restrictions
would you place on it?
Solution
ARGUMENTS FOR:
A DNA database covering the entire populace and each guest to the UK, as upheld by Lord
Justice Sedley, would spare huge measures of police time and help clear up violations quicker.
The individuals who do nothing incorrectly have nothing to fear and ought to be consoled.
The present framework - the DNA of each one of those captured for recordable offenses, liable
or not, is held - is specific and wasteful.
Current practice is uncalled for: ethnic minorities and youngsters are over-spoken to, making
hatred and hostile to police feeling. Two-in-five dark men have their DNA on record, as against
less than one-in-ten whites.
The world has changed: universal versatility implies that potential fear based oppressors can
travel every which way, frequently on false papers.
ARUGMENTS AGAINST:
It would be a definitive stride making progress toward a \'The government\' state: Britain would
turn into \'a country of suspects.
Whatever the utility of DNA tests, there is something inalienably exasperating about entering
each infant on a database during childbirth.
A national DNA bank would be enormously costly and bureaucratic.
It is harming to the picture of the UK - \'Welcome to Britain: now give a mouth swab\'.
DNA data could be mishandled by degenerate police and others wrongfully passing data to
unapproved individuals.
PRIVACY ISSUE:
Individual data is now held by gatherings in the private division, if individuals can believe the
private part then they ought to have the capacity to confide in the Government.
In 2010, the UK Government promised to roll out improvements to the period of time DNA tests
are kept in the UK National DNA Database. These were incorporated into the 2012 Protection of
Freedoms Act. These progressions guarantee that the DNA (and fingerprints) of people captured
yet not indicted an offense is held for a most extreme of 5 years.
The DNA Identification Act of 1994 unequivocally permits database records to be made
accessible for innovative work the length of all actually identifiable data is expelled.
It need not be mandatory for all the individuals but as a matter of national security it should be
taken into consideration.Some restrictions like the privacy issue and the information of that
should not be accessed to everyone instead the government should be in a position to give the
required information neccesary and sho.

How are nuclear pores and porins in the membrane differentSolut.pdf
How are nuclear pores and porins in the membrane different?
Solution
Nuclear pores: are large protein complexes that cross the nuclear envelope, which is the double
membrane surrounding the eukaryotic cell nucleus. There are about an average of 2000 nuclear
pore complexes (NPCs), in the nuclear envelope of a vertebrate cell, but it varies depending on
cell type and the stage in the life cycle.[1] The proteins that make up the nuclear pore complex
are known as nucleoporins. About half of the nucleoporins typically contain solenoid protein
domains—either an alpha solenoid or a beta-propeller fold, or in some cases both as separate
structural domains. Each NPC contains at least 456 individual protein molecules and is
composed of 30 distinct proteins (nucleoporins).
NuclearPorins:nucleoporins are a family of proteins which are the constituent building blocks of
the nuclear pore complex (NPC).[1] The nuclear pore complex is a massive structure that
extends across the nuclear envelope, forming a gateway that regulates the flow of
macromolecules between the cell nucleus and the cytoplasm. Nuclear pores in turn allow the
transport of water-soluble molecules across the nuclear envelope. Nucleoporins, a family of
around 30 proteins, are the main components of the nuclear pore complex in eukaryotic cells.
Nucleoporin 62 is the most abundant member of this family.[2] Nucleoporins are able to
transport molecules across the nuclear envelope at a very high rate. A single NPC is able to
transport 60,000 protein molecules across the nuclear envelope every minute..
How many allotropic forms does uranium have Discuss the effect of a.pdf
How many allotropic forms does uranium have? Discuss the effect of allotropic transformation
on the properties of uranium.
Solution
Metallurgically, uranium metal may exist in three allotropic forms: orthorhombic(alpha),
tetragonal (beta), or body-centered cubic (gamma), and may be alloyed with other metals to alter
its structural and physical properties to suit the application.
Uranium undergoes allotropic transformations around 665 and 770°C.When room temperature
alpha uranium is heated melted it undergoes three distinct transformations, but the
transformations which occur while cooling are important.when the liquid metal solidifies.Slow
cooling results in soft metal, while rapid cooling inreases its hardness.
At room temperature uranium exists in alpha phase which is semi plastic and corrosive. When
heated to beta phase it becomes brittle and hard. The gamma phase is most suited for working as
it can be forged, drawn and extruded..

Explain homologous recombination between human X and Y chromosomes..pdf
Explain homologous recombination between human X and Y chromosomes.
Solution
X and Y chromosomes homology:
The X chromosome is a large sub metacentric chromosome, which contains many genes on it.
Among these genes most are unrelated to sex.
The Y chromosome is a small acrocentric chromosome. In this chromosome 83 active genes are
present, in which most are related to sex determination and spermatogenesis.
The gene of Y chromosome is a pseudogene. It clearly explains the common evolutionary origin.
Homologous recombination between human x and y chromosomes:
In human X and Y chromosomes several homological sequences of regions are identified.
Generally the chromosomes X and Y are paired during in meiosis and undergo crossing over.
these regions are called pseudoautosomal regions., PAR1 and PAR2.
PAR1 crossover is very important in male meiosis. in this chromosomes proper segregation was
occur.
where they exchange only DNA within the pseudoautosomal region at the distal short arms of
both chromosomes.
However, it has been suggested that aberrant recombination involving other segments of high
homology could be responsible for the production of X/Y translocations..

your network with very little configuration out of the box..
By looking at the skeleton of a python, a boa contricor and a legles.pdf
The document discusses evidence that snakes like pythons and boa constrictors evolved from four-legged ancestors. Fossil evidence suggests snakes evolved from burrowing lizards that had legs which became smaller over time as burrowing favored more streamlined bodies. While the ancestor is disputed, the evidence indicates proto-snakes possessed legs that later disappeared as legs were more hindering underground.

Describe the difference between descriptive and inferential statisti.pdf
- 1. Describe the difference between descriptive and inferential statistics. Solution Descriptive and inferential statistics are the two main branches of the science of statistics. Inferential statistics use a random sample of data taken from a population to describe and make inferences about the population. Inferential statistics are valuable when it is not convenient or possible to examine each member of an entire population. Descriptive statistics provide a concise summary of data. You can summarize data numerically or graphically.
