Which standards organization defined the Ethernet standard? A. IEEE B. ISO C. ANSI D. DIX Solution A is correct. IEEE was the first standards body to create Ethernet standards. B, C, and D are incorrect. B is incorrect because ISO created the OSI Reference Model, not the first Ethernet standard. C is incorrect because ANSI is a U.S. standards body that adopts IEEE and other standards. D is incorrect because DIX for Digital Equipment Company, Intel, and Xerox teamed to create the first industry standard, but they are not a standards organization..

iii) Volume ratio = 4/9*(2/3) = 8.27.
Explain how PCBs affect different trophic levels in fish, birds, and .pdf
Explain how PCBs affect different trophic levels in fish, birds, and whales
Solution
The polychlorinated biphenyls (PCBs) are going to affect different trophic levels in fish, birds
and whales (mammalian vertebrates) even at low concentrations may generate relatively high
accumulation of PCB in different biota. The primary consumers (trophic level II in food web)
such as fishes are accumulated with PCB if the aquatic environment is contaminated with high
PCB follo0wed by transfer of POCB to birds when they consume small fishes in the aquatic
environment (trophic level III). When the marine mammals such as whales are going to eat these
fishes are result in differential pathological changes such as reproductive failures etc. If the
humans (tertiary trophic level) are going to consume these result in toxic effects.
During the global recession of 2008 and 2009, there were many accusa.pdf
During the global recession of 2008 and 2009, there were many accusations of unethical
behavior by Wall Street executives, financial managers, and other corporate officers. At that
time, an article appeared suggesting that part of the reason for such unethical business behavior
may stem from the fact that cheating has become more prevalent among business students. The
article reported that 86% of business students admitted to cheating at some time during their
academic career as compared to 77% of non-business students.
Cheating has been a concern of the dean of the College of Business at Rocky University for
several years. Some faculty members in the college believe that cheating is more widespread at
Rocky than at other universities, while other faculty members think that cheating is not a major
problem at the college. To resolve some of these issues, the dean commissioned a study to assess
the current ethical behavior of business students at Rocky. As part of this study, an anonymous
exit survey was administered to a sample of 90 business students from this years graduating
class. Responses to the following questions were used to obtain data regarding three types of
cheating.
During your time at Rocky, did you ever present work copied off the internet as your own?
____ Yes
____ No
During your time at Rocky, did you ever copy answers off another students exam?
____ Yes
____ No
During your time at Rocky, did you ever collaborate with other students on projects that were
supposed to be completed individually?
____ Yes
____ No
Any student who answered yes to one or more of these questions was considered to have been
involved in some type of cheating. The complete data set is in the file named Rocky.

Describe a data structure to represent sets of elements (each element.pdf
Describe a data structure to represent sets of elements (each element with a unique key) that
would support the following operations: insert(x, A) - insert an element x into A (assume the key
of x is not in .4 yet) count (A, k) - return the number of elements in A with key at least k.
Solution
we can use Hashset for this.a simple code in hashset is given below
public class MyNode
{
...
}
public class MyDataStructure
{
private HashSet nodes = new HashSet();
///
/// Inserts an element to this data structure.
/// If the element already exists, returns false.
/// Complexity is averaged O(1).
///
public bool Add(MyNode node)
{
return node != null && this.nodes.Add(node);
}
///
/// Removes a random element from the data structure.
/// Returns the element if an element was found.
/// Returns null if the data structure is empty.
/// Complexity is averaged O(1).
///
public MyNode Pop()
{
// This loop can execute 1 or 0 times.
foreach (MyNode node in nodes)
{
this.nodes.Remove(node);
return node;
}
return null;
}
}
the unique key can also be achieved using dictioneries
hence code for this is given below:
public class FixedIntDictionary
{
// Our internal node structure.
// We use structs instead of objects to not add pressure to the garbage collector.
// We mantains our own way to manage garbage through the use of a free list.
private struct Entry
{
// The key of the node
internal int Key;
// Next index in pEntries array.
// This field is both used in the free list, if node was removed
// or in the table, if node was inserted.
// -1 means null.
internal int Next;
// The value of the node.
internal T Value;
}
// The actual hash table. Contains indices to pEntries array.
// The hash table can be seen as an array of singlt linked list.
// We store indices to pEntries array instead of objects for performance
// and to avoid pressure to the garbage collector.
// An index -1 means null.
private int[] pBuckets;
// This array contains the memory for the nodes of the dictionary.
private Entry[] pEntries;
// This is the first node of a singly linked list of free nodes.
// This data structure is called the FreeList and we use it to
// reuse removed nodes instead of allocating new ones.
private int pFirstFreeEntry;
// Contains simply the number of items in this dictionary.
private int pCount;
// Contains the number of used entries (both in the dictionary or in the free list) in pEntries
array.
// This field is going only to grow with insertions.
private int pEntriesCount;
///
/// Creates a new FixedIntDictionary.
/// tableBucketsCount should be a prime number
/// greater than the number of items that this
/// dictionary should store.
/// The performance of this hash table will be very bad
/// if you don\'t follow this rule!
///
public FixedIntDictionary(int tableBucketsCount)
{
// Our free list is initially empty.
this.pFirstFreeEntry = -1;
// Initializes the entries array with a minimal amount of items.
this.pEntries = new Entry[8];
// Allocate buckets and initial.
Discuss the assumption that explains why one subtracts one half of t.pdf
Discuss the assumption that explains why one subtracts one half of the total number of censored
observation from the denominator when calculating cumulative incidence?
Solution
The assumption that explains why one subtracts one half of the total number of censored
observation from the denominator when calculating cumulative incidence is that censoring
generally occurs uniformly over a period of time and the individuals were at risks for merely
one-half of the follow up period (Szklo, & Nieto, 2014).

A variety of peach, Desert Peach, has a uniformly skin that is mainly.pdf
A variety of peach, Desert Peach, has a uniformly skin that is mainly with random blotches of
pink. The gene required for called and the are located the same chromosome, chromosome A
spontaneous form this old Man, produces fruit the same white and pink coloring with where the
pink. Which one of the following statements consistent with the appearance of these two
peaches?
Solution
6. A spontaneous mutant can be either insertional of nucleotides or chromosomal rearrangements
on a chromosome. As the old man mutant has fuzziness but only in the pink regions, it might be
due to rearrangement of the fuzziness gene ahead of the pink colour gene due to which it is
expressed in the pink region.
7. When this DNA binding protein is expressed in the old man mutant, the fuzziness is gone,
which means that expression of fuzziness gene is repressed. So it might be this DNA binding
protein is repressing the expression of fuzziness gene..

Float :-
while doing programming you need to store information like floating point number.
for this in high level programming language like C, C++, Java, .NET we use built-in as well as
user defined data types.
so float is a keyword that has typical 4 bytes width and typical range +/- 3.4e +/- 38 (~7 digits)

the diagnostic process for UTIs.
Solution
List two reasons why women are at higher risks for developing UTIs
1 .decline in circulating estrogen
In this stage , a decline in estrogen causes changes in the urinary tract which more susceptible to
infection.
2) the urethra is longer than for women, and it is harder formicroorganisms to bladder to cause a
UTI.
3) women, the a ...n...u...s is closer to the urethra .
4) physical activities like ,sexual activity, wiping, and normal menstrual cycle /discharge, the
bacteria is easier to reachthe urethra.
=====================================================================
============
Tests and methods used to analyze urinary tract infections include:
1 Analysis of urine sample : specialist may request a pee test for lab examination to search for
white platelets, red platelets or microbes. To evade potential defilement of the example, you
might be told to first wipe your genital zone with a clean cushion and to gather the pee
midstream.
2. Developing urinary tract microscopic organisms in a lab. Lab examination of the pee is some
of the time took after by a pee culture. This test tells your specialist what microbes are creating
your disease and which drugs will be best.
3.Making pictures of urinary tract. On the off chance that you are having successive diseases that
your specialist thinks might be brought on by a variation from the norm in your urinary tract, you
may have a ultrasound, a modernized tomography (CT) filter or attractive reverberation imaging
(MRI). Your specialist may likewise utilize a difference color to highlight structures in your
urinary tract. Utilizing a degree to see inside bladder. In the event that you have repetitive UTIs,
your specialist may play out a cystoscopy, utilizing a long, thin tube with a focal point
(cystoscope) to see inside your urethra and bladder. The cystoscope is embedded in your urethra
and went through to your bladder..

AI short essay: need help ASAP
What are the professional, ethical, legal, security and social issues and responsibilities inherent in
designing a toy that will hold conversations with children and transmit the children\'s utterances
over the internet?
Please confine yourself to 250 words or fewer
Solution
There are few issues and responsibilities to consider when designing such a toy. As children\'s
conversations are not matured and may sometmes seem funny to others, such conversations must
be filtered before transmission over the internet. There can be potential hackers trying to listen
and extract valuable information as well. Care must be taken that through such conversations no
personal details or the child\'s identity is transmitted over the internet. Since a child may not be
aware that the conversation is recorded and transmitted, their guardians should be aware of such
features in the toy, otherwise it may cause legal problems in case some the child unknowingly
reveals some important information..

Solution
Answer:
3. Propionibacterium is a gram positive, anaerobic bacteria and is part of the normal microbiota
of the skin and teeth. So, they require anaerobic conditions for their growth.
Staphylococcus on the otherhand is a facultative anaerobe, i.e, they can grow both in aerobic and
anaerobic conditions.
Thus, Staphylococcus has more chances of growth in a wide variety of enviromental conditions
compared to Propionibacterium. So, it causes more contamination..
why is it that cholera and other fecal oral disease continue to be a.pdf
why is it that cholera and other fecal oral disease continue to be a major public health problem in
many parts of the world? even tho we know because of contamination because of fecal oral
route... show evidence and support for opinion
Solution
The fecal–oral disease like cholera is a transmission of pathogens in fecal particles passing from
one host are delivered into the oral cavity of any other host. One of the major problem of
fecal–oral disease in many parts of world is lack of ok sanitation and, often linked to that trouble,
water pollutants with fecal cloth.
The technique of transmission may be simple or involve a couple of steps. Some examples to
support this of routes of fecal–oral transmission is:
-water that are available touch with feces (as an example due to groundwater pollution from pit
latrines) and is then now not treated properly earlier than ingesting
-by shaking a person\'s hand that has been infected by using stool, converting a toddler\'s
diapers, operating in the garden or managing cattle or house pets.
-Meals that has been prepared within the presence of fecal depend
-ailment vectors, like houseflies, spreading contamination from insufficient fecal disposal
including open defecation
-bad or absent hand washing after the usage of the rest room or managing feces (inclusive of
converting diapers)
-bad or absent cleansing of anything that has been in contact with feces
-sexual practices that can contain oral touch with feces, such as anilingus, coprophilia or \"ass to
mouth\".
-Ingesting feces, in kids, or in a mental disease referred to as coprophagia
-ingesting soil (geophagia)
Many evidences are shown:
-Cholera is an acute diarrhoeal infection because of ingestion of food or water contaminated with
the bacterium Vibrio cholerae. Cholera stays a global hazard to public health and an indicator of
inequity and shortage of social improvement. Researchers have envisioned that each yr, there are
kind of 1.3 to four.Zero million cases, and 21 000 to 143 000 deaths global because of cholera.
-During the nineteenth century, cholera unfold the world over from its authentic reservoir within
the Ganges delta in India. Six subsequent pandemics killed thousands and thousands of human
beings across all continents. The present day (seventh) pandemic began in South Asia in 1961,
and reached Africa in 1971 and the Americas in 1991. Cholera is now endemic in many nationss..

Following WWII, a rift emerged between the capitalist nations of the.pdf
Following WWII, the Soviet Union and China emerged as major communist powers but did not always agree on policies. The Soviet Union established control over Eastern Europe through the Brezhnev Doctrine. Initially, China allied closely with the Soviet Union due to Soviet communism being the model, China's need for economic aid, and fear of the US. However, China grew unhappy with Soviet cooperation with the West and believed it had been exploited by the USSR in agreements like the Treaty of Friendship and during the Korean War. Ideological differences and China feeling humiliated by Soviet leaders contributed to a split, demonstrated by events like China supporting Albania against the Soviet Union.
What are the benefits and costs of using a common currency for Germa.pdf
What are the benefits and costs of using a common currency for Germany, Greece, and the EU?
Solution
Benefits:
Europe use to have number of currencies that required complex management and this is all gone
with introduction of European currency the EURO
Euro has increased trade between the european nations
Euro zone still is the largest economy in the world
Euro is a very strong currency
Trade in general became too easy within european borders, Goods, Services, People travelled in
much more efficient way,
Problems:
Rich, Industrial western european nations quickly became beneficiaries of Euro currency
Exports to nations within euro zone increased rapidly creating huge debts in less industrial
nations like greece
Some nations in Europe just did not have kind of sophestication to export to western european
nations so trade deficit increased for those nations
In general Idea of Euro was great, but smaller countries now loose their central bank and cannot
regulate their own currency. They loose fiscal and monetary tools so it becomes too difficult for
them to manage their own economy
European union as one nation is the only way to have Euro, One currency several nations might
not be great idea..

Banks offer various types of accounts, such as savings, checking, cer.pdf
Banks offer various types of accounts, such as savings, checking, certificate of deposits, and
money market, to attract customers as well as meet their specific needs. Two of the most
commonly used accounts are savings and checking. Each of these accounts has various options.
For example, you may have a savings account that requires no minimum balance but has a lower
interest rate. Similarly, you may have a checking account that limits the number of checks you
may write. Another type of account that is used to save money for the long term is certificate of
deposit (CD). In this programming exercise, you use abstract classes and pure virtual functions to
design classes to manipulate various types of accounts. For simplicity assume that the bank
offers three types of accounts: savings, checking, and certificate of deposit, as described next.
Savings accounts: Suppose that the bank offers two types of savings accounts: one that has no
minimum balance and a lower interest rate and another that requires a minimum balance and has
a higher interest rate Checking accounts: Suppose that the bank offers three types of checking
accounts: one with a monthly service charge, limited check writing, no minimum balance, and no
interest, another with no monthly service charge, a minimum balance requirement, unlimited
check writing and lower interest, and a third with no monthly service charge, a higher minimum
requirement, a higher interest rate, and unlimited check writing Certificate of deposit (CD): In an
account of this type, money is left for some time, and these accounts draw higher interest rates
than savings or checking accounts. Suppose that you purchase a CD for six months. Then we say
that the CD will mature in six months. The penalty

Solution
Similarities of Signalling systems:
1. They all involves communication by extracellular signals. It involves six common steps :
Synthesis, Release of signals along molecule by the signalling cell, Transport of signal to target
cell, Detection of signal by specific receptor protein, A change in cellular metabolism, triggered
by receptor-signal complex, Removal of the signal.
2. The receptor proteins exhibit ligand-binding and effector specificity.
3. The basic purpose of cell signalling in eukaryotes is to turn on a gene.
Differentiate between Autocrine, Paracrine,Endocrine and neurocrine signalsAutocrine
SignalingParacrine SignalingEndocrine SignalingNeurocrine SignalingIt is produced by
siganling cells that can also bind to the ligand that is released.It is cell siganling in which the
taarget cell is nearby. It is produced by signaling cells that originate from endocrine cells.In
neurocrine signaling, the neurotransmitter relased form neuronal terminal travels to synaptic
cleft and from their to other cells.Autocrine means that the chemical signals acts on the same
cellsParacrine means that the chemical signals acts on the adjacent cells.Endocrine means
chemical signals acts at different sites (after travelling through blood vessesl)It is similar to
paracrine but involves neurons.No diffusion is present. The cell signal moves by itself.Paracrine
signals move by diffusion through extracellular matrix.No diffusion occurs. It is relatively slow
process.It occurs the same way as paracrine sigals but with nerve cells.Example: Cytokine
interleukin-1 in monocytes.Example: Growth factors and clotting factors are paracrine signaling
agents.For example: The hormones like testosterone etc.Example: Transfer of signals across

1 OverviewFor this lab, you will implement the insert method and t.pdf
1 Overview
For this lab, you will implement the insert method and toString method of
a PointList class. The main method creates a PointList object, then prompt
the user for pairs of x and y (integer) values in a continuous (innite) loop.
Each unique pair the user enters should be inserted into the correct position in
the list according to its distance from the origin (0; 0). By constructing the list
one point at a time, we have the opportunity to easily keep it sorted without
having to sort it separately later. This technique is similar to insertion sort. Be
sure to use the appropriate overloaded add method in the ArrayList class. If
the user enters a duplicate point, it should be ignored (think about how can you
tell if it\'s a duplicate). Whenever a new point is added to the list, the contents
of the list should be printed, along with the point\'s distance from the origin.

There are few issues and responsibilities to consider when designing such a toy. As children\'s
conversations are not matured and may sometmes seem funny to others, such conversations must
be filtered before transmission over the internet. There can be potential hackers trying to listen
and extract valuable information as well. Care must be taken that through such conversations no
personal details or the child\'s identity is transmitted over the internet. Since a child may not be
aware that the conversation is recorded and transmitted, their guardians should be aware of such
features in the toy, otherwise it may cause legal problems in case some the child unknowingly

why is it that cholera and other fecal oral disease continue to be a major public health problem in
many parts of the world? even tho we know because of contamination because of fecal oral
route... show evidence and support for opinion
Solution
The fecal–oral disease like cholera is a transmission of pathogens in fecal particles passing from
one host are delivered into the oral cavity of any other host. One of the major problem of
fecal–oral disease in many parts of world is lack of ok sanitation and, often linked to that trouble,
water pollutants with fecal cloth.
The technique of transmission may be simple or involve a couple of steps. Some examples to
support this of routes of fecal–oral transmission is:
-water that are available touch with feces (as an example due to groundwater pollution from pit
latrines) and is then now not treated properly earlier than ingesting
-by shaking a person\'s hand that has been infected by using stool, converting a toddler\'s
diapers, operating in the garden or managing cattle or house pets.
-Meals that has been prepared within the presence of fecal depend
-ailment vectors, like houseflies, spreading contamination from insufficient fecal disposal
including open defecation
-bad or absent hand washing after the usage of the rest room or managing feces (inclusive of
converting diapers)
-bad or absent cleansing of anything that has been in contact with feces
-sexual practices that can contain oral touch with feces, such as anilingus, coprophilia or \"ass to
mouth\".
-Ingesting feces, in kids, or in a mental disease referred to as coprophagia
-ingesting soil (geophagia)
Many evidences are shown:
-Cholera is an acute diarrhoeal infection because of ingestion of food or water contaminated with
the bacterium Vibrio cholerae. Cholera stays a global hazard to public health and an indicator of
inequity and shortage of social improvement. Researchers have envisioned that each yr, there are
kind of 1.3 to four.Zero million cases, and 21 000 to 143 000 deaths global because of cholera.
-During the nineteenth century, cholera unfold the world over from its authentic reservoir within
the Ganges delta in India. Six subsequent pandemics killed thousands and thousands of human

Following WWII, a rift emerged between the capitalist nations of the.pdf
Following WWII, the Soviet Union and China emerged as major communist powers but did not always agree on policies. The Soviet Union established control over Eastern Europe through the Brezhnev Doctrine. Initially, China allied closely with the Soviet Union due to Soviet communism being the model, China's need for economic aid, and fear of the US. However, China grew unhappy with Soviet cooperation with the West and believed it had been exploited by the USSR in agreements like the Treaty of Friendship and during the Korean War. Ideological differences and China feeling humiliated by Soviet leaders contributed to a split, demonstrated by events like China supporting Albania against the Soviet Union.
What are the benefits and costs of using a common currency for Germa.pdf
What are the benefits and costs of using a common currency for Germany, Greece, and the EU?
Solution
Benefits:
Europe use to have number of currencies that required complex management and this is all gone
with introduction of European currency the EURO
Euro has increased trade between the european nations
Euro zone still is the largest economy in the world
Euro is a very strong currency
Trade in general became too easy within european borders, Goods, Services, People travelled in
much more efficient way,
Problems:
Rich, Industrial western european nations quickly became beneficiaries of Euro currency
Exports to nations within euro zone increased rapidly creating huge debts in less industrial
nations like greece
Some nations in Europe just did not have kind of sophestication to export to western european
nations so trade deficit increased for those nations
In general Idea of Euro was great, but smaller countries now loose their central bank and cannot
regulate their own currency. They loose fiscal and monetary tools so it becomes too difficult for
them to manage their own economy
European union as one nation is the only way to have Euro, One currency several nations might
not be great idea..
What is the difference of the rational expression below 14x17-3x1.pdf
What is the difference of the rational expression below? 14x/17-3x/17 17x/17 11x/17 42x/17
42x/289
Solution
Denominators are the same
So, we can directly subtract numerators as below :
(14x - 3x) / 17
Now, what is 14 - 3? That,s right, it\'s 11
So, 14x - 3x is 11x, right?
So, the answer is :
11x/17
Option B.

Banks offer various types of accounts, such as savings, checking, cer.pdf
Banks offer various types of accounts, such as savings, checking, certificate of deposits, and
money market, to attract customers as well as meet their specific needs. Two of the most
commonly used accounts are savings and checking. Each of these accounts has various options.
For example, you may have a savings account that requires no minimum balance but has a lower
interest rate. Similarly, you may have a checking account that limits the number of checks you
may write. Another type of account that is used to save money for the long term is certificate of
deposit (CD). In this programming exercise, you use abstract classes and pure virtual functions to
design classes to manipulate various types of accounts. For simplicity assume that the bank
offers three types of accounts: savings, checking, and certificate of deposit, as described next.
Savings accounts: Suppose that the bank offers two types of savings accounts: one that has no
minimum balance and a lower interest rate and another that requires a minimum balance and has
a higher interest rate Checking accounts: Suppose that the bank offers three types of checking
accounts: one with a monthly service charge, limited check writing, no minimum balance, and no
interest, another with no monthly service charge, a minimum balance requirement, unlimited
check writing and lower interest, and a third with no monthly service charge, a higher minimum
requirement, a higher interest rate, and unlimited check writing Certificate of deposit (CD): In an
account of this type, money is left for some time, and these accounts draw higher interest rates
than savings or checking accounts. Suppose that you purchase a CD for six months. Then we say
that the CD will mature in six months. The penalty

Solution
20) Opening a File Means we are accessing the file from memory and we are loading it from
external Memory to Virtual Memory.
Logical I/O means the data is treated as sequence of blocks that are nmbered from 0 ti N-1
Physical I/O treats them by sector,platter.
21) Access methods refer to a mechanism of accessing data whereas device driver is a software
that looks after particular devices connected to our machine internally or externally.
22) Processor bus is defined as the bus that provides the path for communication between the
main buses send the central processing unit
The memory bus is the computer bus which connects the main memory to the memory controller
in computer systems.
A system bus is a single computer bus that connects the major components of a computer
system, combining the functions of a data bus to carry information, an address bus to determine
where it should be sent, and a control bus to determine its operation.
The I/O Bus. A personal computer may transfer data from disk to CPU, from CPU to memory, or
from memory to the display adapter.
23) If we are having more than one command set for execution then it is known as Batch
Command File
24) Below are few functions
a) Opening a File b) Closing a File 3) Renaming a File etc..
25) Opening a File means we are physically accessing a resource that is predefined and
launching a program means we are externally loading the data that is not predefined.
They are similar as both need the data to be transferred externally and difference are in terms of
their functionalities

List the Bergey’s Manual group number and Bergey’s characteristics of Enterobacteiaceae.
What are the IMViC battery of differential tests?
Solution
a. Bergey\'s manual is mainly used in the identification of prokaryotic organisms. Most of the
unknown prokaryotes fall in groups which are listed as follows:
1. The gram -ve aerobic/microaerophilic cocci and rods fall in group 4.
2. The faculatative gram -ve rods come under group 5.
3. The gram +ve cocci fall in group 17.
4. Endospore forming gram +ve cocci as well as rods fall under group 18.
5. Nonsporing regular gram +ve rods come under group 19.
6. Nonsporing irregular gram +ve rods come under group 20.
7. The last most common group is group 21 which contains all the aerobic, nonsporing,
nonmotile, acid-fast, weakly gram +ve rods.
b. The IMViC of differential tests is an acronym for each of the tests.
I stands for indole test.
M stands for Methyl red test.
V stands for Voges-Proskauer test.

Solution
Similarities of Signalling systems:
1. They all involves communication by extracellular signals. It involves six common steps :
Synthesis, Release of signals along molecule by the signalling cell, Transport of signal to target
cell, Detection of signal by specific receptor protein, A change in cellular metabolism, triggered
by receptor-signal complex, Removal of the signal.
2. The receptor proteins exhibit ligand-binding and effector specificity.
3. The basic purpose of cell signalling in eukaryotes is to turn on a gene.
Differentiate between Autocrine, Paracrine,Endocrine and neurocrine signalsAutocrine
SignalingParacrine SignalingEndocrine SignalingNeurocrine SignalingIt is produced by
siganling cells that can also bind to the ligand that is released.It is cell siganling in which the
taarget cell is nearby. It is produced by signaling cells that originate from endocrine cells.In
neurocrine signaling, the neurotransmitter relased form neuronal terminal travels to synaptic
cleft and from their to other cells.Autocrine means that the chemical signals acts on the same
cellsParacrine means that the chemical signals acts on the adjacent cells.Endocrine means
chemical signals acts at different sites (after travelling through blood vessesl)It is similar to
paracrine but involves neurons.No diffusion is present. The cell signal moves by itself.Paracrine
signals move by diffusion through extracellular matrix.No diffusion occurs. It is relatively slow
process.It occurs the same way as paracrine sigals but with nerve cells.Example: Cytokine
interleukin-1 in monocytes.Example: Growth factors and clotting factors are paracrine signaling
agents.For example: The hormones like testosterone etc.Example: Transfer of signals across
synapse in nerve cells..
1 OverviewFor this lab, you will implement the insert method and t.pdf
1 Overview
For this lab, you will implement the insert method and toString method of
a PointList class. The main method creates a PointList object, then prompt
the user for pairs of x and y (integer) values in a continuous (innite) loop.
Each unique pair the user enters should be inserted into the correct position in
the list according to its distance from the origin (0; 0). By constructing the list
one point at a time, we have the opportunity to easily keep it sorted without
having to sort it separately later. This technique is similar to insertion sort. Be
sure to use the appropriate overloaded add method in the ArrayList class. If
the user enters a duplicate point, it should be ignored (think about how can you
tell if it\'s a duplicate). Whenever a new point is added to the list, the contents
of the list should be printed, along with the point\'s distance from the origin.
2 Sample Output
Enter x, y values (type 0 0 to exit): 2 3

- 1. Which standards organization defined the Ethernet standard? A. IEEE B. ISO C. ANSI D. DIX Solution A is correct. IEEE was the first standards body to create Ethernet standards. B, C, and D are incorrect. B is incorrect because ISO created the OSI Reference Model, not the first Ethernet standard. C is incorrect because ANSI is a U.S. standards body that adopts IEEE and other standards. D is incorrect because DIX for Digital Equipment Company, Intel, and Xerox teamed to create the first industry standard, but they are not a standards organization.
