You will want to look at electronegativity differ.pdf
You will want to look at electronegativity differences between elements in a
molecule. Ionic bonds will only occur when the difference of electronegativity for the bonding
elemets is high, such as Sodium (very low electronegativity) and Chlorine (very high
electronegativity). Depending on which chemistry you are taking, you could even go as simple is
ionic bonding occurs only when bonding elements on different sides of the periodic table.
Phosphorous and Antimony are fairly close to Chlorine, and thus will form a covalent bond. To
find out whether it is polar or non-polar, you must look closer into the difference of
electronegativity in the entire molecule, but for this example, just take a quick glance at a Lewis
Dot Diagram. If the molecule is symmetric (like most organic chemicals), the molecule is non-
polar (like most organic chemicals). If the molecule is not symmetric, it will be polar, like water.

Well 1-Heptanol is a straight chained 7 carbon mo.pdf
Well 1-Heptanol is a straight chained 7 carbon molecule with an OHgroup attached
to one end, to state the obvious. Because 1-Heptanol is longer than Ethanol, the Oxygen does
not havemuch of an effect on the electron distribution at the far end ofthe molecule. Conversely,
Ethanol has two carbons attached toan OH group. The electrons around those two carbons
aregreatly affected by the OH group. So if you made a map of polarity of each of these
molecules, theentire Ethanol molecule would likely be affected by the OHgroup. In 1-Heptanol,
the polarity would be concentrated nearthe OH group, but the other end of the molecule would
likely beunaffected by the presence of the OH group. Therefore theEthanol molecule is more
polar, because the entire molecule\'selectron density is affected. Does this make sense? If you
have any questions about myexplanation or you want clarification please ask.

Waters bent structure leads to its polar nature.pdf
Water\'s bent structure leads to its polar nature, which is the cause for most of its
unique properties. It the molecule were straight, it would not be polar and this would be quite
disruptive. Water would no longer be strongly attracted to itself or other polar molecules. So
water would no longer have surface tension. Insects which walk on water would fall through.
Water would have a far lower boiling point, so it would evaporate much more easily. Also,
boiling water would no longer be hot enough to cook food. The hydrogen bonding character of
water would change, resulting in that ice would no longer be less dense than liquid water, and
therefore ice would sink to the bottom of bodies of water. Most disastrous would be the effect on
living things. Water would no longer be a solvent and so anything which is dissolved in water in
animal\'s bodies would come out of solution. Ions and electrolytes would come out of the water
and clump up in the body. Without water to dissolve things, the blood could no longer carry
certain essential chemicals to the cells, nor could it carry certain toxic wastes away from cells.
Cellular metabolism would soon cease to function and life as we know it would for the most part
cease. ===================== If water were a linear molecule, would it still be polar? 1
Yes No .Would the water molecules still be able to form hydrogen bonds with one another? 2
Yes No . ANsWER Answer Details 1. no 2. yes. note: if the water molecule is linear, the net
dipole moment is zero. thus, it is not polar. However, the O-H bond is still polar due to the
different electronegativity of O and H atoms. Thus, the H---O-H hydrogen bonds still exist.

What is the relationship between Accounting and an Accounting inform.pdf
What is the relationship between Accounting and an Accounting information system? (2.5
Marks)
Accounting-Methods, procedures, and standards followed in accumulating, classifying,
recording, and reporting business events and transactions. The accounting system includes the
formal records and original source data. Regulatory requirements may exist on how a particular
accounting system is to be maintained (e.g., insurance company).
Accounting Information System-Subsystem of a Management Information System (MIS) that
processes financial transactions to provide (1) internal reporting to managers for use in planning
and controlling current and future operations and for nonroutine decision making; (2) external
reporting to outside parties such as to stockholders, creditors, and government agencies.
• What has happened to the relationship over the years? (2.5 Marks)
Accounting and Information technology are two terms which are the used in every business .
Because both are needed for effective working of a corporate or company. It is the need of time
that we should understand the relationship between Accounting and Information Technology .
Accounting is related recording and utilisation of recorded data . Information technology is
scientific , technological , engineering disciplines and management technique used in
information handling and processing , their application , computers and their interaction with
men and machines and associated , economical and cultural matters . In Simple wording IT is
that technique which and get and utilize the information with effective and efficient way.
Now , we are ready for giving the relationship between Accounting And Information
technology.
Both are related to get information and utilization of that information . So both are
interconnected with each other . If our specialize of both area merge both system with scientific
and technical way , then they easily overcome the different problems due to lack of correct and
adequate information related to business.
• What is accounting information? (1 marks)
Accounting information can be classified into two categories: financial accounting or public
information and managerial accounting or private information. Financial accounting includes
information disseminated to parties that are not part of the enterprise proper—stockholders,
creditors, customers, suppliers, regulatory commissions, financial analysts, and trade
associations—although the information is also of interest to the company\'s officers and
managers. Such information relates to the financial position, liquidity (that is, ability to convert
to cash), and profitability of an enterprise.
Managerial accounting deals with cost-profit-volume relationships, efficiency and productivity,
planning and control, pricing decisions, capital budgeting, and similar matters. This information
is not generally disseminated outside the company. Whereas the general-purpose financial
statements of financial accounting are assumed.

The transport of sodium ions and glucose into the cell is through sy.pdf
The transport of sodium ions and glucose into the cell is through symnport. For every two
sodium ions transported into cell, one glucose is also transported in the same direction. The
concentration gradient of sodium is used to transport glucose into the cell, against its own
concentration gradient (that is, irrespective of the concentration of glucose). This is why, though
the glucose concentration inside the cell is higher compared to the cell exterior, glucose is
transported inside.
In the given experiment, the concentration of sodium ions inside the cell is initially low or very
less. There is a large concentration gradient of Na+ ions, due to which they are transported into
the cell easily. Glucose is also transported along with, without any hindrance. When equilibrium
is attained between the cell exterior and the cell interior with respect to sodium ions, there is no
net movement of ions into the cell. Therefore, symport of glucose is stopped.
When the concentration of extracellular Na+ ions increases, the concentration gradient also
increases as a result of which there is high net movement of Na+ ions into the cells. The cells
reaches equilibrium quickly, and this is why the plateau is reached.
B. Leaky channels allow leaking of Na+ and K+ ions to leak down their concentration gradient.
Therefore, apart from Na+ K+ pump, the channels also transport the ions, without transporting
glucose. Therefore, less glucose enters the cells, the cells reach equilibrium quickly.

Large companies are immensely powerful entities, to the point that t.pdf
Large companies are immensely powerful entities, to the point that they have frequently trumped
the interests of sovereign nations. American businessmen deposed the queen of Hawai\'i in 1893
because they were incensed with her tariff policies. The formerly independent country became an
American territory a few years later. Corporate interests frequently harm local communities, as
in 1928 when the Colombian army massacred an unknown number of striking United Fruit
Company workers. The U.S. had threatened a military invasion of Colombia to protect the
company\'s interests.
Corporations can have enormously detrimental effects on the environment. Oil spills are some of
the most conspicuous examples, but industries as varied as chemical manufacturing, mining,
agriculture and fishing can do permanent damage to local ecosystems. Climate change can also
be attributed in large part to corporations. While their responsibility is hard to untangle from that
of the consumers who demand electricity and transportation, it is difficult to deny that many
corporations have profited from the deterioration of the global environment.
In many cases, harm to the environment and harm to vulnerable communities go hand-in-hand:
indigenous groups in the Amazon rainforest, for example, have been decimated and even wiped
out, both intentionally and unintentionally, in order to make room for logging, cattle ranching,
gold mining, oil and gas drilling and hydroelectric power generation.
In light of this often dark legacy, some areas of corporate culture have begun to embrace a
philosophy that balances the pursuit of profit with a commitment to ethical conduct. Google
Inc\'s (GOOG) slogan sums up the idea of corporate social responsibility nicely: \"Don\'t be
evil.\"
The same money and influence that enable large companies to inflict damage on people and the
environment allows them to effect positive change. At its simplest, a corporation can give money
to charity. Companies can also use their influence to pressure governments and other companies
to treat people and resources more ethically. When Martin Luther King, Jr. won the Nobel Peace
Prize in 1964, Atlanta\'s business leaders initially refused to attend a dinner celebrating the
Atlanta native\'s achievement. Coca Cola Co.\'s (KO) CEO, recognizing the damage such a
display of segregationist attitudes could do to the firm\'s international brand, threatened to move
Coke out of the city, causing an immediate change of heart in the local business elite.
Companies can invest in local communities in order to offset the negative impact their operations
might have. A natural resources firm that begins to operate in a poor community might build a
school, offer medical services or improve irrigation and sanitation equipment. Similarly, a
company might invest in research and development in sustainable technologies, even though the
project might not immediately lead to increased profitability.

Immune System Cells are of various types. However, they are divided .pdf
Immune System Cells are of various types. However, they are divided mainly into two types
based on their type of response-
Cells of the Innate/ Non-Specific Immune System- These are the cells which have the natural or
inborn capacity of defence. They defend the host from infection by any foreign organisms, but
their effect is not long lasting.
These mainly comprise of: Natural killer cells, mast cells, eosinophils, basophils, macrophages,
neutrophils, and dendritic cells, and function within the immune system by identifying and
eliminating pathogens that might cause infection.Mast cells act by rapidly releasing characteristic
granules, rich in histamine and heparin, along with various hormonal mediators and chemokines,
or chemotactic cytokines into the environment. Histamine dilates blood vessels, causing the
characteristic signs of inflammation.Eosinophils, basophils, neutrophils kill foreign cells by
releasing toxic substances which are present in their granules like hydrogen peroxide and free
oxygen radicals. Macrophages, neutrophils and dendritic cells act by phagocytosis. This is a
process by which the foreign body is engulfed by the immune cell and then kill it by releasing
granules or respiratory burst.
Cells of the Adaptive Immune System- These are the cells which response to a specific antigen
containing foriegn body. These antigens specifically react to initiate the Adaptive immunity.
Adaptive immunity creates immunological memory after an initial response to a specific
pathogen, and leads to an enhanced response to subsequent encounters with that pathogen. This
process of acquired immunity is the basis of vaccination. Cells of the Adaptive Immune
Systemmainly comprises of the B-lymphocytes and the T-.lymphocytes. B-lymphocytes bear
certain receptors on their surface called antibodies, for which the anigen has sequences called
epitopes, due to which specific binding with the antibody occurs. This antigen-antibody binding
results in precipitation or some other form of degradation and thus,the foreign substance is
eliminated out of the host\'s body.
T-lymphocytes are of two types. Cytotoxic T cells (also known as TC, killer T cell, or cytotoxic
T-lymphocyte (CTL)) are a sub-group of T cells that induce the death of cells that are infected
with viruses (and other pathogens), or are otherwise damaged or dysfunctional. These could be
by release of cytotoxic granules or by Fas mediated killing. Another, group of T-Lymphocytes
called T-helper cells help in activating the cytotoxic cells. They help in presenting the antigen to
the adaptive immune system and releases cytokines that increases the activity of the adaptive
immune system

What is the relationship between Accounting and an Accounting inform.pdf
What is the relationship between Accounting and an Accounting information system? (2.5
Marks)
Accounting-Methods, procedures, and standards followed in accumulating, classifying,
recording, and reporting business events and transactions. The accounting system includes the
formal records and original source data. Regulatory requirements may exist on how a particular
accounting system is to be maintained (e.g., insurance company).
Accounting Information System-Subsystem of a Management Information System (MIS) that
processes financial transactions to provide (1) internal reporting to managers for use in planning
and controlling current and future operations and for nonroutine decision making; (2) external
reporting to outside parties such as to stockholders, creditors, and government agencies.
• What has happened to the relationship over the years? (2.5 Marks)
Accounting and Information technology are two terms which are the used in every business .
Because both are needed for effective working of a corporate or company. It is the need of time
that we should understand the relationship between Accounting and Information Technology .
Accounting is related recording and utilisation of recorded data . Information technology is
scientific , technological , engineering disciplines and management technique used in
information handling and processing , their application , computers and their interaction with
men and machines and associated , economical and cultural matters . In Simple wording IT is
that technique which and get and utilize the information with effective and efficient way.
Now , we are ready for giving the relationship between Accounting And Information
technology.
Both are related to get information and utilization of that information . So both are
interconnected with each other . If our specialize of both area merge both system with scientific
and technical way , then they easily overcome the different problems due to lack of correct and
adequate information related to business.
• What is accounting information? (1 marks)
Accounting information can be classified into two categories: financial accounting or public
information and managerial accounting or private information. Financial accounting includes
information disseminated to parties that are not part of the enterprise proper—stockholders,
creditors, customers, suppliers, regulatory commissions, financial analysts, and trade
associations—although the information is also of interest to the company\'s officers and
managers. Such information relates to the financial position, liquidity (that is, ability to convert
to cash), and profitability of an enterprise.
Managerial accounting deals with cost-profit-volume relationships, efficiency and productivity,
planning and control, pricing decisions, capital budgeting, and similar matters. This information
is not generally disseminated outside the company. Whereas the general-purpose financial
statements of financial accounting are assumed.

The transport of sodium ions and glucose into the cell is through sy.pdf
The transport of sodium ions and glucose into the cell is through symnport. For every two
sodium ions transported into cell, one glucose is also transported in the same direction. The
concentration gradient of sodium is used to transport glucose into the cell, against its own
concentration gradient (that is, irrespective of the concentration of glucose). This is why, though
the glucose concentration inside the cell is higher compared to the cell exterior, glucose is
transported inside.
In the given experiment, the concentration of sodium ions inside the cell is initially low or very
less. There is a large concentration gradient of Na+ ions, due to which they are transported into
the cell easily. Glucose is also transported along with, without any hindrance. When equilibrium
is attained between the cell exterior and the cell interior with respect to sodium ions, there is no
net movement of ions into the cell. Therefore, symport of glucose is stopped.
When the concentration of extracellular Na+ ions increases, the concentration gradient also
increases as a result of which there is high net movement of Na+ ions into the cells. The cells
reaches equilibrium quickly, and this is why the plateau is reached.
B. Leaky channels allow leaking of Na+ and K+ ions to leak down their concentration gradient.
Therefore, apart from Na+ K+ pump, the channels also transport the ions, without transporting
glucose. Therefore, less glucose enters the cells, the cells reach equilibrium quickly.

epitopes, due to which specific binding with the antibody occurs. This antigen-antibody binding
results in precipitation or some other form of degradation and thus,the foreign substance is
eliminated out of the host\'s body.
T-lymphocytes are of two types. Cytotoxic T cells (also known as TC, killer T cell, or cytotoxic
T-lymphocyte (CTL)) are a sub-group of T cells that induce the death of cells that are infected
with viruses (and other pathogens), or are otherwise damaged or dysfunctional. These could be
by release of cytotoxic granules or by Fas mediated killing. Another, group of T-Lymphocytes
called T-helper cells help in activating the cytotoxic cells. They help in presenting the antigen to
the adaptive immune system and releases cytokines that increases the activity of the adaptive
immune system
Solution
Immune System Cells are of various types. However, they are divided mainly into two types
based on their type of response-
Cells of the Innate/ Non-Specific Immune System- These are the cells which have the natural or
inborn capacity of defence. They defend the host from infection by any foreign organis.
Hi,The discount window is a policy which is governed by the centra.pdf
Hi,
The discount window is a policy which is governed by the central bank that allows the financial
institution to borrow money from the central bank on a short term basis. After the 9/11
incidents, Federal Reserve added $100 billion in liquidity per day, during the three days
following the attack, to help avert a financial crisis. Now, this was an important step to boost the
economy. The action provided the much needed liquidity for the various financial institutions to
function
