Stereoisomers are isomeric molecules that have th.pdf
Stereoisomers are isomeric molecules that have the same molecular formula and
sequence of bonded atoms (constitution), but that differ only in the three-dimensional
orientations of their atoms in space. This contrasts with structural isomers, which share the same
molecular formula, but the bond connections and/or their order differ(s) between different
atoms/groups. In stereoisomers, the order and bond connections of the constituent atoms remain
the same, but their orientation in space differ. stereo isomers are classifides in to two types
(1)enantiomers (2)diastereomers Enantiomers are two stereoisomers that are related to each other
by a reflection: They are mirror images of each other, which are non-superimposable. Human
hands are a macroscopic example of stereoisomerism. Every stereogenic center in one has the
opposite configuration in the other. Two compounds that are enantiomers of each other have the
same physical properties, except for the direction in which they rotate polarized light and how
they interact with different optical isomers of other compounds. As a result, different
enantiomers of a compound may have substantially different biological effects. Pure enantiomers
also exhibit the phenomenon of optical activity and can be separated only with the use of a chiral
agent. In nature, only one enantiomer of most chiral biological compounds, such as amino acids
(except glycine, which is achiral), is present. Diastereomers are stereoisomers not related through
a reflection operation. They are not mirror images of each other. These include meso
compounds, cis-trans (E-Z) isomers, and non-enantiomeric optical isomers. Diastereomers
seldom have the same physical properties. In the example shown below, the meso form of
tartaric acid forms a diastereomeric pair with both levo and dextro tartaric acids, which form an
enantiomeric pair.

Salt dissolving in water physical or chemical Def.pdf
Salt dissolving in water physical or chemical Definition Salt water - Salt water or
saltwater may refer to: Saline water, water containing dissolved salts; Brine, water saturated or
nearly saturated with salt; Brackish water, water that is saltier ..... Solubility equilibrium -
Solubility equilibrium is any type of chemical equilibrium relationship between solid and
dissolved states of a compound at saturation. Solubility equilibria involve application of
chemical principles and constants to predict solubility of substances under specific conditions
(because solubility is sensitive to the conditions, while the constants are less so). The substance
that is dissolved can be an organic solid such as sugar or an ionic solid such as table salt. The
main difference is that ionic solids dissociate into constituent ions when they dissolve in water.
Most commonly water is the solvent of interest, although the same basic principles apply with
any solvent. In the case of environmental science studies of water quality, the total concentration
of dissolved solids (not necessarily at saturation) is referred to as total dissolved solids.
Dissolution of an organic solid can be described as an equilibrium between the substance in its
solid and dissolved forms:.... Salt water - Saline water, water containing dissolved salts; Brine,
water saturated or nearly saturated with salt; Brackish water, water that is saltier than fresh

Multicasting:
It is the communication between a single sender and multiple receivers on a network. Typical
uses include the updating of mobile workers from a home office and the episodic issuance of
online newsletters
IGMP works as:
Internet Group Management Protocol is allows a host to promote its multicast group membership
to adjacent switches and routers. IGMP is used by the TCP/IP protocol set to achieve dynamic
multicasting
When a multicast transmission initiates the software creates a multicast group. This multicast
group address consists of an IP address by the first octet in the range 224 – 239 and is particular
in the IP packet as the end address for this traffic. The host initiate the transmission send a
message to the 224.0.0.2 address specify the multicast group address. And the switch receives
this message and adds the multicast group to its table and adds the receiving port as a member of
the group.
PIM works as:
The PIM protocol can be configured to work on IPv4 and IPv6 networks.
Multicast protocols are used to carry multicast packets from one source to multiple receivers.
They ease better bandwidth use and use less host and router processing and ideal for usage in
applications such as video and audio. PIM is a usually used multicast routing protocol.
SDN:
Software Defined Networking is an upcoming architecture that is dynamic, manageable and
adaptable of making it perfect for the dynamic nature of today\'s applications.
Open Flow:
Open Flow is enable for researchers to run experimental protocols in the campus networks we
use every day. Open Flow is added as a feature to saleable Ethernet switches, routers and
wireless access points and provide a regular hook to allow researchers to run experiments
without require vendors to expose the inner workings of their network devices.

IntroductionFew things are more aggravating to produce on a worksi.pdf
Introduction
Few things are more aggravating to produce on a worksite than concrete. Bags of cement, sand,
aggregate (gravel) and possibly other additives must be delivered to the construction area. A
supply of clean water is also necessary, along with a rented concrete mixing hopper. Even after
all the dusty and heavy ingredients have been loaded into the hopper, one small error in the
wet/dry ratio can render an entire batch of concrete unusable. One common solution to this
messy and time-consuming problem is “READY MIX CONCRETE”.
Ready-mix concrete (RMC) is a ready-to-use material, with predetermined mixture of cement,
sand, aggregates and water. RMC is a type of concrete manufactured in a factory according to a
set recipe or as per specifications of the customer, at a centrally located batching plant.
It is delivered to a worksite, often in truck mixers capable of mixing the ingredients of the
concrete en route or just before delivery of the batch. This results in a precise mixture, allowing
specialty concrete mixtures to be developed and implemented on construction sites. The second
option available is to mix the concrete at the batching plant and deliver the mixed concrete to the
site in an agitator truck, which keeps the mixed concrete in correct form.
In the case of the centrally mixed type, the drum carrying the concrete revolves slowly so as to
prevent the mixed concrete from \"segregation\" and prevent its stiffening due to initial set.
However, in the case of the truck-mixed concrete, the batched materials (sand, gravel and
cement) are carried and water is added just at the time of mixing. In this case the cement remains
in contact with the wet or moist material and this phase cannot exceed the permissible period,
which is normally 90 minutes.
The use of the RMC is facilitated through a truck-mounted \'boom placer\' that can pump the
product for ready use at multi-storied construction sites. A boom placer can pump the concrete
up 80 meters.
Objective -
Manufacturing process of ready mix concrete.
Procedure –
Materials required for RMC –
Admixture: A substance added to the basic concrete mixture to alter one or more properties of
the concrete; i.e. fibrous materials for reinforcing, water repellent treatments, and coloring
compounds.
Aggregate: Inert particles (i.e. gravel, sand, and stone) added to cement and water to form
concrete.
Cement: Dry powder that reacts chemically with water to bind the particles of aggregate,
forming concrete. Portland cement is typically used in concrete production.
Fly ash: Fly ash is a by-product from coal-fired electricity generating power plants. The coal
used in these power plants is mainly composed of combustible elements such as carbon,
hydrogen and oxygen (nitrogen and sulfur being minor elements), and non-combustible
impurities (10 to 40%) usually present in the form of clay, shale, quartz, feldspar and limestone.
As the coal travels through the high-temperature zone in the furnace, the combus.

AnswerRecombinant DNA Technology It is the set of techniques tha.pdf
Answer:
Recombinant DNA Technology: It is the set of techniques that enables the DNA from different
sources to be identified, isolated, and recombined so that new characterstics can be introduced
into an organism. One of the main techniques in recombinant DNA technology is DNA cloning.
The DNA cloning produces an unlimited number of copies of a particular DNA segment (from a
single ancestral DNA molecule). The Recombinant DNA Technology was engineered by Stanley
Norman Cohen and Herbert Boyer in 1973.
The cell based DNA cloning involve following 4 steps:
1) Construction of recombinant DNA molecule: The hybrid DNA molecules are constructed by
in-vitro covalant attachment (ligation) of the desired DNA fragments to a replicon.
2) Transformation: The recombinant DNA molecules are transferred into host cells, in which the
chosen replicon can undergo DNA replication.
3) Selective propogation of cell clones: The targeted cells were propogated in the selective liquid
medium.
4) Isolation of recombinant DNA clones: The recombinant DNA clones are selectively isolated.
* The enzymes used in the recombinant DNA technology are basically of 4 types:
DNA polymerase, Nucleases, Restriction Enzymes, Isoschizomers
Restriction enzymes: Most naturally occuring DNA molecules are much larger than can be
readily analysed in the lab. To study individual gene and individual site on DNA, the large DNA
molecules must be broken into small (managable) fragments. This could be done using
restriction enzymes. The restriction enzymes are bacterial enzymess that able to cut double-
stranded DNA molecules (by cleaving the phosphodiester bonds) at a specific nucleotide
sequence, called a restriction site. The term restriction comes from the fact that these enzymes
restrict the entry of foreign DNA in the bacteria. There are some enzymes that cut a three base
pair sequence while others can cut four, six, and even eight base pair target sequence in a DNA
molecule, usually palindromic.
The naturally occurring restriction endonucleases are categorized into four groups (Types I, II
III, and IV) based on their composition and enzyme cofactor requirements, the nature of their
target sequence, and the position of their DNA cleavage site relative to the target sequence.
For example: the one widely used restriction enzyme, EcoRI, named because it was found in
certain strain of Escherichia coli and was the first (I) such enzyme found in that species.
Plasmids: Plasmid are naturally occuring cicular, extrachromosomal, autonomously replicating
DNA, present in many prokaryotic and few eukaryotic organisms. These are range in size from 1
Kbp to over 300 Kbp. The cloning vectors, replicating genetic element used to carry a fragment
of target DNA into a host cell for the purpose of cloning. The important features of a plasmid are

Some genetic diseases are called as complex or multifactirial because they are caused due the
combined effect of more than one factors (gene mutation along with environmental factors) and
therefore they are complex un nature. For example if there is mutation in TGFA gene in a
pregnant mother and sge is also exposed to smoking, she will have a significant risk of having
cleft lip/palate in her child. Any of the two factor alone is not sufficient to cause disaese.

Alcohols are organic molecules that have a very p.pdf
Alcohols are organic molecules that have a very polar -OH unit somewhere. That\'s
the soluble part, or the \"Like\" part that interacts with water. For instance methanol (CH3OH)
or ethanol (CH3CH2OH) are infinitely soluble in water or miscible with water. As the organic
molecule gets bigger, e.g., (CH3CH2CH2CH2CH2CH2CH2CH2CH2-OH) then the interactions
of the other part of the molecule, or the nonpolar part of the molecule become very significant.
Since these types of interactions are mostly dispersive in nature, water has a harder time
disrupting those interactions to cause the solvation process to proceed.

A NEWVIEW OF GRAVITYEntropy and Gravity may be crucial concepts fo.pdf
A NEWVIEW OF GRAVITY
Entropy and Gravity may be crucial concepts for explaining roots of familiar force.
Gravity may be defined as masses attract each other. To scholars you could explain that space-
time is warped by mass Or that without gravity, the laws of physics would differ for people
moving at changing velocities.
Such a simple question, has defied a direct answer for centuries. A flurry of recent papers have
examined this new idea, which mixes principles from string theory and black hole physics with
basic old-fashioned thermodynamics.
Nobody has expressed the gravity-as-entropy except theorist Erik Verlinde of the University of
Amsterdam in an online paper(arXiv.org/abs/1001.0785v1). His recipe replicates Newton\'s law
of gravitational attraction, and then with some additional mathematical seasoning he arrives at
Einstein\'s general relativity, the modern and undefeated champion of gravity theories.
Verlinde\'s analysis indicates that gravity emerges from physical dynamics analogous to basic
thermodynamic processes. \"Using only … concepts like energy, entropy and temperature,\" he
writes, \"Newton\'s laws appear naturally and practically unavoidably.\"
some extending Verlinde\'s idea to encompass the history of the universe. Rapid expansion just
after the Big Bang and the more recent accelerating expansion of the universe might all fit into
the entropic-gravity picture of reality.
Entropy means \"disorder,\" with a tendency for higher entropy taken to mean that things like to
get messier any system not resupplied with useful energy reaches equilibrium, and entropy is
maximized. More technically, it is a measure of how likely a system is to be in its particular
configuration. Low entropy describes systems with a very improbable arrangement of their parts.
Curiously, the equations relating entropy to probability are precisely the same as the math used
by computer scientists to quantify information. As the molecules spread out, information about
their location diminishes and entropy rises.
Such loss of information--or increasing entropy--drives many natural processes, such as osmosis,
the mysterious migration of water across a membrane.
In 1995, Ted Jacobson of the University of Maryland demonstrated that the equations of
Einstein\'s general theory of relativity could be derived from basic thermodynamic principles,
who discovered parallels between ordinary thermodynamics and the physics of black holes.
Bekenstein showed that a black hole has entropy, determined by all the matter and energy it has
swallowed. Hawking demonstrated that black holes have a temperature. Since black holes are
basically nothing more than pure gravity.
In 1993 Dutch Nobel physics laureate Gerard \'t Hooft. proposed that reality shares common
features with holograms, like the flashy images embedded in credit cards that store apparently
three-dimensional information on a flat surface. In a similar way, \'t Hooft asserted, information
about the contents in three-d.

1. Water supplies are treated with chlorine to kill pathogens. Chlor.pdf
1. Water supplies are treated with chlorine to kill pathogens. Chlorine reacts well with many
other chemicals because it is a strong oxidant. What does this mean?
Answer: Option 4 Because chlorine is strongly electronegative and needs one electron to fill its
outer shell, it strongly pulls electrons from other substances.
Explanation: Chlorine is known to be one of the most electronegative atoms of the periodic table
( with a value of approx 3 in the pauling scale). This means that it has a very strong tendancy to
attract electron. Also Chlorine (Atomic number 17, configuration of electrons 2, 8, 7) has seven
electrons in the valence shell so it needs one electron to fill its outer shell .
2. Tests to monitor water safety often report the number of fecal coliform bacteria found in
samples. Which of the following statements accurately reflects water safety recommendations
based upon fecal coliform levels?
Answer : Here by mistake the first two options are exactly same, one of them probably needs to
be corrected to
If the level of fecal coliform bacteria is low, then the water is safe for drinking and recreational
purposes.
This option will be the correct option.
Explanation: Fecal coliforms are bacteria which indicate that the water might have been exposed
to fecal matter. They are an excellant proxy to make sure that the water doesn\'t contain any
human pathogens. So if the Fecal coliforms count is low it indicates that the chances of water
containing any human pathogen is also low and therefore it can be used for drinking and
recreational purposes
3. When an individual has severe diarrhea, as can occur with cholera, rehydration solution with
glucose, salt, sodium bicarbonate, and potassium chloride can be administered. Why is it
important to use a solution like this rather than simply giving the individual water?
Answer: Option 1: Diarrhea causes the loss of electrolytes, not just fluids, and it is important to
replace the electrolytes as well. Glucose is transported into intestinal epithelial cells, along with
sodium, by symporters. It is included as well because glucose is not sufficiently absorbed while
sodium is lacking.
Explanation: The answer is self explanatory
4.Vibrio cholerae is a human pathogen that causes cholera. It has an unusual shape distinctive of
its genus. Considering that it does not have one of the most common bacterial shapes, what is the

IntroductionFew things are more aggravating to produce on a worksi.pdf
Introduction
Few things are more aggravating to produce on a worksite than concrete. Bags of cement, sand,
aggregate (gravel) and possibly other additives must be delivered to the construction area. A
supply of clean water is also necessary, along with a rented concrete mixing hopper. Even after
all the dusty and heavy ingredients have been loaded into the hopper, one small error in the
wet/dry ratio can render an entire batch of concrete unusable. One common solution to this
messy and time-consuming problem is “READY MIX CONCRETE”.
Ready-mix concrete (RMC) is a ready-to-use material, with predetermined mixture of cement,
sand, aggregates and water. RMC is a type of concrete manufactured in a factory according to a
set recipe or as per specifications of the customer, at a centrally located batching plant.
It is delivered to a worksite, often in truck mixers capable of mixing the ingredients of the
concrete en route or just before delivery of the batch. This results in a precise mixture, allowing
specialty concrete mixtures to be developed and implemented on construction sites. The second
option available is to mix the concrete at the batching plant and deliver the mixed concrete to the
site in an agitator truck, which keeps the mixed concrete in correct form.
In the case of the centrally mixed type, the drum carrying the concrete revolves slowly so as to
prevent the mixed concrete from \"segregation\" and prevent its stiffening due to initial set.
However, in the case of the truck-mixed concrete, the batched materials (sand, gravel and
cement) are carried and water is added just at the time of mixing. In this case the cement remains
in contact with the wet or moist material and this phase cannot exceed the permissible period,
which is normally 90 minutes.
The use of the RMC is facilitated through a truck-mounted \'boom placer\' that can pump the
product for ready use at multi-storied construction sites. A boom placer can pump the concrete
up 80 meters.
Objective -
Manufacturing process of ready mix concrete.
Procedure –
Materials required for RMC –
Admixture: A substance added to the basic concrete mixture to alter one or more properties of
the concrete; i.e. fibrous materials for reinforcing, water repellent treatments, and coloring
compounds.
Aggregate: Inert particles (i.e. gravel, sand, and stone) added to cement and water to form
concrete.
Cement: Dry powder that reacts chemically with water to bind the particles of aggregate,
forming concrete. Portland cement is typically used in concrete production.
Fly ash: Fly ash is a by-product from coal-fired electricity generating power plants. The coal
used in these power plants is mainly composed of combustible elements such as carbon,
hydrogen and oxygen (nitrogen and sulfur being minor elements), and non-combustible
impurities (10 to 40%) usually present in the form of clay, shale, quartz, feldspar and limestone.
As the coal travels through the high-temperature zone in the furnace, the combus.

AnswerRecombinant DNA Technology It is the set of techniques tha.pdf
Answer:
Recombinant DNA Technology: It is the set of techniques that enables the DNA from different
sources to be identified, isolated, and recombined so that new characterstics can be introduced
into an organism. One of the main techniques in recombinant DNA technology is DNA cloning.
The DNA cloning produces an unlimited number of copies of a particular DNA segment (from a
single ancestral DNA molecule). The Recombinant DNA Technology was engineered by Stanley
Norman Cohen and Herbert Boyer in 1973.
The cell based DNA cloning involve following 4 steps:
1) Construction of recombinant DNA molecule: The hybrid DNA molecules are constructed by
in-vitro covalant attachment (ligation) of the desired DNA fragments to a replicon.
2) Transformation: The recombinant DNA molecules are transferred into host cells, in which the
chosen replicon can undergo DNA replication.
3) Selective propogation of cell clones: The targeted cells were propogated in the selective liquid
medium.
4) Isolation of recombinant DNA clones: The recombinant DNA clones are selectively isolated.
* The enzymes used in the recombinant DNA technology are basically of 4 types:
DNA polymerase, Nucleases, Restriction Enzymes, Isoschizomers
Restriction enzymes: Most naturally occuring DNA molecules are much larger than can be
readily analysed in the lab. To study individual gene and individual site on DNA, the large DNA
molecules must be broken into small (managable) fragments. This could be done using
restriction enzymes. The restriction enzymes are bacterial enzymess that able to cut double-
stranded DNA molecules (by cleaving the phosphodiester bonds) at a specific nucleotide
sequence, called a restriction site. The term restriction comes from the fact that these enzymes
restrict the entry of foreign DNA in the bacteria. There are some enzymes that cut a three base
pair sequence while others can cut four, six, and even eight base pair target sequence in a DNA
molecule, usually palindromic.
The naturally occurring restriction endonucleases are categorized into four groups (Types I, II
III, and IV) based on their composition and enzyme cofactor requirements, the nature of their
target sequence, and the position of their DNA cleavage site relative to the target sequence.
For example: the one widely used restriction enzyme, EcoRI, named because it was found in
certain strain of Escherichia coli and was the first (I) such enzyme found in that species.
Plasmids: Plasmid are naturally occuring cicular, extrachromosomal, autonomously replicating
DNA, present in many prokaryotic and few eukaryotic organisms. These are range in size from 1
Kbp to over 300 Kbp. The cloning vectors, replicating genetic element used to carry a fragment
of target DNA into a host cell for the purpose of cloning. The important features of a plasmid are
as follows:

a. Major categories1. Chromosomal disorders Due to numerical or .pdf
a. Major categories:
1. Chromosomal disorders: Due to numerical or physical abnormality at the chromosome level.
2. Monogenic disorders: Due to mutation in single gene
3. Complex/Multifactorial disorders: Due to mutation in one or more than one genes together
with extrinsic factors.
Some genetic diseases are called as complex or multifactirial because they are caused due the
combined effect of more than one factors (gene mutation along with environmental factors) and
therefore they are complex un nature. For example if there is mutation in TGFA gene in a
pregnant mother and sge is also exposed to smoking, she will have a significant risk of having
cleft lip/palate in her child. Any of the two factor alone is not sufficient to cause disaese.
b. According CDC, the leading causes of death are 1.heart attacks followed by 2, cancers,
3.respiratory diseases, 4.accidents, 5.stroke, 6.Alzheimer\'s disease, 7.diabetes,
8.influenza/pneumonia, 9.nephritis/nephrotic syndrome/nephrosis and 10.suicide. Of these
1,2,3,5,6, and 7 have genetic sysceptibility and comes under complex/multifactorial disorders. 3

Alcohols are organic molecules that have a very p.pdf
Alcohols are organic molecules that have a very polar -OH unit somewhere. That\'s
the soluble part, or the \"Like\" part that interacts with water. For instance methanol (CH3OH)
or ethanol (CH3CH2OH) are infinitely soluble in water or miscible with water. As the organic
molecule gets bigger, e.g., (CH3CH2CH2CH2CH2CH2CH2CH2CH2-OH) then the interactions
of the other part of the molecule, or the nonpolar part of the molecule become very significant.
Since these types of interactions are mostly dispersive in nature, water has a harder time
disrupting those interactions to cause the solvation process to proceed.

A NEWVIEW OF GRAVITY
Entropy and Gravity may be crucial concepts for explaining roots of familiar force.
Gravity may be defined as masses attract each other. To scholars you could explain that space-
time is warped by mass Or that without gravity, the laws of physics would differ for people
moving at changing velocities.
Such a simple question, has defied a direct answer for centuries. A flurry of recent papers have
examined this new idea, which mixes principles from string theory and black hole physics with
basic old-fashioned thermodynamics.
Nobody has expressed the gravity-as-entropy except theorist Erik Verlinde of the University of
Amsterdam in an online paper(arXiv.org/abs/1001.0785v1). His recipe replicates Newton\'s law
of gravitational attraction, and then with some additional mathematical seasoning he arrives at
Einstein\'s general relativity, the modern and undefeated champion of gravity theories.
Verlinde\'s analysis indicates that gravity emerges from physical dynamics analogous to basic
thermodynamic processes. \"Using only … concepts like energy, entropy and temperature,\" he
writes, \"Newton\'s laws appear naturally and practically unavoidably.\"
some extending Verlinde\'s idea to encompass the history of the universe. Rapid expansion just
after the Big Bang and the more recent accelerating expansion of the universe might all fit into
the entropic-gravity picture of reality.
Entropy means \"disorder,\" with a tendency for higher entropy taken to mean that things like to
get messier any system not resupplied with useful energy reaches equilibrium, and entropy is
maximized. More technically, it is a measure of how likely a system is to be in its particular
configuration. Low entropy describes systems with a very improbable arrangement of their parts.
Curiously, the equations relating entropy to probability are precisely the same as the math used
by computer scientists to quantify information. As the molecules spread out, information about
their location diminishes and entropy rises.
Such loss of information--or increasing entropy--drives many natural processes, such as osmosis,
the mysterious migration of water across a membrane.
In 1995, Ted Jacobson of the University of Maryland demonstrated that the equations of
Einstein\'s general theory of relativity could be derived from basic thermodynamic principles,
who discovered parallels between ordinary thermodynamics and the physics of black holes.
Bekenstein showed that a black hole has entropy, determined by all the matter and energy it has
swallowed. Hawking demonstrated that black holes have a temperature. Since black holes are
basically nothing more than pure gravity.
In 1993 Dutch Nobel physics laureate Gerard \'t Hooft. proposed that reality shares common
features with holograms, like the flashy images embedded in credit cards that store apparently
three-dimensional information on a flat surface. In a similar way, \'t Hooft asserted, information
about the contents in three-d.

1A) One of the best explanation for why we conform/obey in the real world is, generally people
are concerned over the thinking of other people. They tend to behave in such manner that they
can correlate with others in properties like behaviors, belief, attitudes and feelings.
1B) Participants obey the researcher is also based on the above explanations. The participants
obey because the researchers have more knowledge and information than them and the other fact
is the participants have to be in norms of research, institute or centre. So they have to obey
researchers.
2A) No; such obedience is not always beneficial. There are many examples where pupils are
tending to obey the researcher in such a way that they can even forget the ethical rules. Obeying
societal norms and expectations sometimes create disturbing behavior. Society is made of people
so the welfare of people will create welfare society.
2B) Deviant behavior is the behavior which denies the societal norms and expectations. They are
not harmful always. The criminal mind from deviant behavior can be created if it is from
abnormal, inappropriate or dysfunctional mental processes. This is relied to individual’s
personality.

1. Water supplies are treated with chlorine to kill pathogens. Chlor.pdf
1. Water supplies are treated with chlorine to kill pathogens. Chlorine reacts well with many
other chemicals because it is a strong oxidant. What does this mean?
Answer: Option 4 Because chlorine is strongly electronegative and needs one electron to fill its
outer shell, it strongly pulls electrons from other substances.
Explanation: Chlorine is known to be one of the most electronegative atoms of the periodic table
( with a value of approx 3 in the pauling scale). This means that it has a very strong tendancy to
attract electron. Also Chlorine (Atomic number 17, configuration of electrons 2, 8, 7) has seven
electrons in the valence shell so it needs one electron to fill its outer shell .
2. Tests to monitor water safety often report the number of fecal coliform bacteria found in
samples. Which of the following statements accurately reflects water safety recommendations
based upon fecal coliform levels?
Answer : Here by mistake the first two options are exactly same, one of them probably needs to
be corrected to
If the level of fecal coliform bacteria is low, then the water is safe for drinking and recreational
purposes.
This option will be the correct option.
Explanation: Fecal coliforms are bacteria which indicate that the water might have been exposed
to fecal matter. They are an excellant proxy to make sure that the water doesn\'t contain any
human pathogens. So if the Fecal coliforms count is low it indicates that the chances of water
containing any human pathogen is also low and therefore it can be used for drinking and
recreational purposes
3. When an individual has severe diarrhea, as can occur with cholera, rehydration solution with
glucose, salt, sodium bicarbonate, and potassium chloride can be administered. Why is it
important to use a solution like this rather than simply giving the individual water?
Answer: Option 1: Diarrhea causes the loss of electrolytes, not just fluids, and it is important to
replace the electrolytes as well. Glucose is transported into intestinal epithelial cells, along with
sodium, by symporters. It is included as well because glucose is not sufficiently absorbed while
sodium is lacking.
Explanation: The answer is self explanatory
4.Vibrio cholerae is a human pathogen that causes cholera. It has an unusual shape distinctive of
its genus. Considering that it does not have one of the most common bacterial shapes, what is the
shape of this species?
Answer Option 2 - Curved rod
Explanation:Vibrio\'s unique curved rod shape is also called the \"comma\" shape. Just helps to
remember it more easily
5. Legionella pneumophilia can grow in water and is transmitted in aerosols. Which of these has
an infection NOT been linked to?
Answer option 4 -ocean water
6. On a global scale, the most important waterborne bacterial pathogens are __________.
Answer Option 4 -Vibrio cholerae and Salmonella enterica serovar Typhi
