Prevention technologies are dynamic in the sense that they are put in place and generally left alone. True or False? Explain your answer. Solution Answer: False Prevention technologies are static in the sense that they are put in place and generally left alone. it does not say that they are not regularlly evaluted and updated on need basis. But these technologies are designed to serve static manner. Where as Dectection anf response technologoes are dynamic and on going process to monitor the security violations or risks..

Need 2 -3 paragraph
Considering the aesthetics of the late 19th century, how, in your opinion, did 19th century artists
influence Modernism in the 20th century? Use at least one example of 19th century art in your
response as a basis for your analysis.
Solution
Modernism : it is a philosophical development that, alongside social patterns and changes,
emerged from wide-scale and expansive changes in Western culture amid the late nineteenth and
mid twentieth hundreds of years. Among the elements that formed innovation were the
improvement of present day modern social orders and the quick development of urban areas,
took after then by responses of ghastliness to World War I. Innovation additionally dismisses the
conviction of Enlightenment considering, and numerous pioneers rejected religious conviction.
An eminent normal for innovation is reluctance and incongruity concerning scholarly and social
conventions, which regularly prompted to explores different avenues regarding structure,
alongside the utilization of methods that attracted consideration regarding the procedures and
materials utilized as a part of making a canvas, ballad, building, and so on.
modernism unequivocally dismisses the philosophy of authenticity and makes utilization of the
works of the past by the work of repeat, joining, modifying, reiteration, update and farce. Present
day specialists explored different avenues regarding better approaches for seeing and with crisp
thoughts regarding the way of materials and elements of workmanship. An inclination far from
the account, which was trademark for the customary expressions, toward deliberation is normal
for much present day craftsmanship. Later imaginative generation is frequently called
contemporary craftsmanship or postmodern workmanship..

List three sources of variability in material properties. If that va.pdf
List three sources of variability in material properties. If that variability can be reduced, describe
how.
Solution
Homogeneous materials: A material of uniform composition throughout that cannot be
mechanically separated into different materials. Examples of homogeneous materials are certain
types of plastics, ceramics, glass, metals, alloys, paper, board and resins.
Isotropic materials: Isotropic material means a material having identical values of a property in
all directions. Glass and metals are examples of isotropic materials.
Anisotropy materials: It is a term used in various scientific disciplines to indicate that certain
properties of matter (such as a material or radiation) vary with the direction from which they are
measured. For instance, if the refractive index or density of a material is different when
measured along different axes, that property is said to be anisotropic.Anisotropy is the opposite
of isotropic, a term used when properties are the same when measured from any direction.
Orthotropic materrials: In materials science and solid mechanics, orthotropicmaterials have
material properties that differ along three mutually orthogonal twofold axes of rotational
symmetry. They are a subset of anisotropic materials, because their properties change when
measured from different directions.
A design is expected to have a good concept about mechanical properties of materials. Different
manufacturing methods and heat treatment can change the materials properties.
Engineering materials are divided as follows:-
1. Metal and Metal Alloys; Example: Iron, Copper, Nickel etc.
2. Non- Metals; Example: Ceramics, rubber, glass etc.
Important Mechanical Properties of Materials are Described Below
a. Strength: This describes the ability to resist any external force. Without Yielding (Yield point
is that point at which plastic deformation starts) breaks.
b. Stiffness: This is measured by modulus of elasticity. It is ability of the material to prevent
deformation when stress is applied.
There are many mechanical properties are present .
The mechanical properties of a materialare those which effect the mechanical strength and ability
of material to be molded in suitable shape. Some of the typical mechanical properties of a
material are listed below-
Strength
Toughness
Hardness
Hardenability
Brittleness
Malleability
Ductility
Creep and Slip
Resilience
Fatigue.

making and testing a prediction
suppose that after 22 months, guppies from the transplanted population were returned to the
source pool.what would most likely happen to those guppies.
Solution
Answer:
1) Due to habitat change the feeding frequency affect
2) Predation problem: Guppies have many predators, such as larger fish and birds, in their
natural habitats. Some of their common predators in the wild are Crenicichla alta, Anablepsoides
hartii, and Aequidens pulcher. Guppies\' small bodies and the bright coloration of males make
them easy prey, and like many fish, they often school together to avoid predation..
Life is wholly dependent on water. List and discuss two reasons why .pdf
Life is wholly dependent on water. List and discuss two reasons why this is?!!
Solution
Life is wholly dependent on water because,
1). Plants get the carbon dioxide necessary for photosynthesis in exchange with water
2). Animals use water in several ways such as, to transport the molecules in the body, to maintain
body temperature, to excrete the waste, etc.
As plants are the primary producers, their survival is the key for survival of the remaining
organisms. The biological cycle will be terminated if there is no water because the platn\'s
survival needs water..

John Rawls argued that societys goal should be to lessen the welfar.pdf
John Rawls argued that society\'s goal should be to lessen the welfare of the most well off
property rights should be equally distributed among all citizens.
Solution
Rawls refers to “the two principles of Justice as Fairness,” but the second has two parts. These
principles address two different aspects of the basic structure of society: the “First Principle”
addresses the essentials of the constitutional structure. It holds that society must assure each
citizen “an equal claim to a fully adequate scheme of equal basic rights and liberties, which
scheme is compatible with the same scheme for all.”
So answer here will be B..

Identify the distinguishing characteristics of member of Phylum Cnid.pdf
Identify the distinguishing characteristics of member of Phylum Cnidaria, including symmetry,
number of embryonic tissue layers, unique structures, skeleton and polymorphism (polyp and
medusa), place Cnidaria on a cladogram
Compare and contrast how a general polyp and a medusa feed
Describe why a nerve net was such a major evolutionary adaptation
Describe the characteristics of the four classes of Cnidarians
Label the following on a drawing: tentacles, mouth, anus, gastrovascular cavity, cnidocytes,
nerve net
Solution
Answer1) Symmetry- Radially symmetrical body
Number of embryonic tissue layers- two (endoderm and ectoderm)
Unique structures- Stinging cells (Cnidocytes)
Skeleton- Hydrostatic skeleton
Polymorphism (polyp and medusa)- polyp is a flower like solitary form and medusa is a free-
floating miniature of cnidarians.
Answer 2) a tubular shaped body form is called as polyp. They are sessile and are found as
attached bottom (basal plate) to a solid surface with the opened mouth at the top. while medusa is
an umbrella or bell shape form, having their mouth facing downwards. And they are free
floating. Being a sessile, polyp filter their food from the water by their tiny-beating cilia. While
medusas are free floating and motile so they can trap their feedings, and need not to filter the
water all the time though these structures were more related to the sexual reproduction.
Answer 3) Nerve net is a diffused framework of neurons in the body which can transmit
signals/impulse in different directions from a single point of stimulus.
This became a major evolutionary adaptation because it allowed the organism to sense the
environmental stimulus from any region of its body and respond accordingly. This allowed the
readily development and motion of different body parts such as limb like structures.
Answer 4) These are the four classes of cnidarians.
Hydrozoa are diploblastic and multicellular animals. Which has only mouth opening. They have
a fixed polyp stage and the reproductive medusa stage. They have the gonads as well.
Scyphozoan are present in medusoid forms. They have tentaculocysts as Sense organs. They
have Velarium in endodermal canal (Acraspedote). They endodermal gonads.
Anthozoan are present only in polyp forms. Their medusa stage is absent. They have Mesenteries
which bear nematocyst. They also possess endodermal Gonads.
Cubozoan looks like the jelly fish and called as jelly boxes. They possess box shaped medusa
and they share typical characteristics of scyphozoans..
If most evolutionary change occurs during and immediately after spec.pdf
If most evolutionary change occurs during and immediately after speciation, could speciation
rates and extinction rates explain major patterns in macroevolution? In turn, what factors may
influence speciation and extinction rates (are they all biological, or can geological /
meteorological / astronomical factors also play a role)?
Solution
In the course of evolution, some mutations keep on occurring with every replicative step. These
mutations lead to differences in alleles, which further result in different genotypes. Some
genotypes have higher fitness while others have lower fitness. Natural selection selects the
phenotypes which have higher fitness, and slowly discards the others during the course of
evolution. So, extinction rate depends on fitness and natural selection.
As new phenotypes are selected, they result in formation of new species; the process is known as
speciation. Speciation further results in evolution. Higher the speciation rate, higher will be the
rate of evolution.
So, you can say that most evolutionary changes occur during and after speciation.
Overall the biological factors affecting speciation and extinction rates are:
It is important to note that that apart from the above two factors, geological/astronomical factors
also affect speciation, extinction and evolution. Changes in the earth since times immemorial
ultimately resulted in changes like:.
Imagine that someone picking up roses in a garden gets a scratch fro.pdf
Imagine that someone picking up roses in a garden gets a scratch from a thorn. Some bacteria
(Staphyloccocus aureus and Streptococcus pyogenes) take advantage of the wound to gain access
to the deeper layers of the skin and attempt to cause an infection. Describe the different stages of
the host response (in particular the types of cells and receptors involved) and how the bacteria
will be recognized and eliminated.
Solution
The superficial staphylococcal and streptococcal infections are very common in skin. The
physiological condition of the skin is much suitable to these bacteria. Both these bacteria are
potent toxin and enzyme producing strains.
S.auresus infection on the skin immediately stimulates the inflammatory response and
macrophages and neutrophils are proliferated at the site of infection. The organism can enter the
body through openings in the skin barrier like hair follicles and can cause infections like
folliculitis, pimples, furuncle which is type of abscess. The furuncles also damage the
neighboring tissue by invading deep in to the tissue. This is known as carbuncle. Staphylococci
cause a highly contagious skin infection in children known as impetigo. The impetigo is two
types-nonbullous impetigo is caused by both S.aureus and S.pyogenes; bullous impetigo is
caused by staphylococcal toxin. It is also known as staphylococcal scalded skin syndrome. At
later stages of toxic shock syndrome the scalded skin syndrome is the characteristic feature.
Streptococci also secrete toxin and enzymes. The toxins are called hemolysins that lyse the red
blood cells. Various hemolysins like alpha, beta and gamma are produced by various
streptococcus strains. S.pyogenes is an important beta hemolytic streptococcus. Streptococcus
skin infections are generally superficial but some times may reach the deeper tissues also.
S.pyogenes infects the dermis of the skin and also causes a disease known as erysipelas in which
the skin erupts in to reddish patches.
The skin scraping is cultured and stained to observe the bacteria under microscope.
Staphylococci and streptococci both are gram positive and round shaped bacteria. The
staphylococci occur as grape-like clusters (Staphylococci name indicates bunch of grapes in
Greek). The streptococci are arranged in chains or pairs. Topical antibiotics like Mupirocin and
oral antibiotics like first generation cephalosporins and erythromycin are used to eliminate the
bacteria..
I need help working out this question . woman has normal vision al.pdf
I need help working out this question .
woman has normal vision although her maternal grandfather (her mother’s father) had red-
green colorblindness, a sex-linked recessive trait. Her maternal grandmother and the woman’s
own father are assumed to not possess a copy of the mutant allele. The woman marries a man
with normal vision although his father was colorblind. What is the probability that the first child
of this couple will be colorblind?
Solution
As it is x linked inheritance, the genotype of women is either xx = Normal or xxc =Carrier for
disease. If she is carrier (xxc) and married normal man, then the probability of 1st chaild getting
colour blindness is 1/4 = 0.25
Color blind ness is x linked and it inherit criss cross manner. That mean, male transfer color
blindness to her female children and. female transfer her male children.
XXc x XY ----------------> XX, XY, XXc & XcY
XcY progeny is only colour blind. So probability is 1\\4.

How con osmosis work for and against homeostasis How do osmosis .pdf
How con osmosis work for and against homeostasis? How do osmosis and diffusion relate to
dialysis? (Short paragraph o fine)
Solution
Multi cellular organisms should maintain a balance between internal and external environments
to carry out proper metabolic activities. The maintenance of relatively stable environment
internally is known as homeostasis.
All the body functions carried out by various systems of the body contribute to the homeostasis
to maintain a stable environment in the body for its survival and function. Homeostasis is much
required and the vital force for the each cell and through performing specialized activity, each
cells maintain a stable internal environment.
The net diffusion of water down the concentration gradient through the selectively permeable
membrane is called osmosis..
Enzymes and KE. Whats the relationship in terms of substrate mo.pdf
Enzymes and KE. What\'s the relationship in terms of substrate molecules
Enzymes and KE. What\'s the relationship in terms of substrate molecules
Solution
ANS:
Enzyme KE(kinetic energy)and substrate molecules relationship:
When the temperature raises the kinetic energy of reactants is also raised, increasing in
temperature results in higher activation energy molecules and more molecular (enzyme and
substrate) collision and interaction for the reaction to proceed faster.
The enzymes present in the human body usually need 37.5 o C (optimal temperature). The
optimum temperature for most of the enzymes between 40-45o C.
In this condition rate is increased. Increasing substrate concentration means an increasing rate at
which the enzyme and substrate molecules encounter one another
In general, the enzymes are exposed to a temperature above 50 o C, denaturing leading to
derangement in native structure. Majority of enzymes became inactive at higher temperature
above 70 o C
In enzymes at higher temperatures intra and intermolecular bonds are broken down, so the
enzyme molecules gain even more kinetic energy.
After reaching the maximum point, the rate of the reaction suddenly fall down due to the enzyme
degradation..
Explain membranes. Include the definition and name the four types an.pdf
Explain membranes. Include the definition and name the four types and which tissues each type
contains.
Solution
Answer : Membranes are the flat sheets of pliable tissue that cover or line a part of the body. The
combination of an epithelial layer and an underlying connective tissue layer constitutes an
epithelial membranes. These includes,
Mucous membranes : These membranes lines the body cavity that opens directlyto the exterior.
Mucous membranes lines the entire digestive, respiratory and reproductive tracts and much of
the urinary tract.
Serous Membranes : A serous membrane or Serosa lines a body cavity that does not open
directly to the exterior and it covers the organs that lie within the cavity.serous membranes
consist of areolar connective tissue covered by mesothelium and also consists of two layers such
as Parietal and visceral layer.
Cutaneous Membrane : These membarnes covers the surface of the body and consists of a
superficial portion called the epidermis and a deeper portion called the dermis.
Synovial Membranes : Like serous membranes, synovial membranes line structures that do not
open to the exterior. They lack in epithelium and are composed of discontinuous layer of cells
called synoviocytes, which secretes synovial fluid. Synovial fluid lubricates and nourishes the
cartilage covering the bones at movable joints and contains macrophages that moves microbes
and debris from the joint cavity..

Clinical immunology questionMr. R.M., a 60-year-old Caucasian man,.pdf
Clinical immunology question
Mr. R.M., a 60-year-old Caucasian man, was stung by a bee while gardening. He had been stung
once before earlier in the summer. Within a few seconds, his hand began to itch and he began to
experience abdominal cramping. He subsequently began experiencing difficulty breathing.
Fortunately, he was able to reach a first aid kit in his garage. Inside of the kit was an EpiPen
(injectable epinephrine) that his wife kept for herself because she was allergic to bee venom. He
immediately had his wife drive him to the hospital.
He was asymptomatic on arrival at the hospital. R.M. had no history of adverse reactions to bee
venom or antibiotics. Because of the nature of the incident, a diagnosis of anaphylactic shock
due to bee venom sensitivity was made. An IgE level was ordered. The results indicated a level
more than twice the (normal) reference range value. In addition, a follow-up skin test was
performed. The patient was extremely positive for bee venom.
Questions:
1.Which of the 4 types of hypersensitivity reactions does this case represent?
2.What is the immunologic mechanism involved in anaphylaxis?
3.What types of agents can induce anaphylactic shock?
4.Describe 2 different types of testing to diagnosis this patient.
5.What is the risk in performing a skin test?
Solution
Answer:
1) There are four types of hypersensitivity reactions, they include:
1) Type - I ; Allergy , 2) Type- II ; Cytotoxic, antibody-dependent, 3) Type III; Immune
complex disease
4) Type IV; Delayed-type hypersensitivity.
2) Anaphylaxis is an Type-I reaction ; allergic reaction. During allergic reaction, IgE react with
antigen, and it activates basophils and mast cells, due this activation, histamines are released.
3) Anaphylactic shock could be due to the food agents such as milk, eggs and shellfish. In few
cases, insect stings can cause shock.
4) Diagnosis includes, 1) Allergy testing (skin allergy test), 2)Differential diagnosis.
5) Skin test is available only to test effect of penicillin drug allergy.so, it is risk for allergies..
As shown in the pedigree below, a pair of first cousins (I and K) ma.pdf
As shown in the pedigree below, a pair of first cousins (I and K) marry an unrelated pair of first
cousins (J and L). Their children M and N produce child O.
1. Calculate the inbreeding coefficient (f) of O (express answers to 1 and 3 to three decimal
places). Assume that f= 0 for all ancestors. (Hint: To help you out, I have shaded individuals
who cannot contribute to autozygosity.) To show your work, use the letter names to indicate each
path/loop that contributes to autozygosity. For example: path 1 = M-I-E…
2. Interpret your result. What does this value of f indicate?
3. Recalculate f for child O when f=1/2 for great-great grandmother D (f=0 for all other
ancestors). Hint: After you have calculated all the loops above, you’ll adjust just the loop that
includes ancester D to account for her ancestral inbreeding using the formula presented in class

ancestors). Hint: After you have calculated all the loops above, you\'ll adjust just the loop that
includes ancester D to account for her ancestral breeding using the formula presented in class
(and text)
Solution
1. Path 1:
So, the probability that a copy of gene in A makes the way down to O via E and a copy of gene
in B makes the way down to O via F =( ½)n = (½)7=0.00781. Here n= node=7
Path 2:
Similarly like the first one the total probability in path 2 will be same that is 0.00781.
Thus inbreeding co-efficient = 0.00781+0.00781=0.01562.
2. Generally, the higher the level of inbreeding closer the coefficient of relationship approaches a
value of 1 and approaches a value of 0 for individuals with remote common ancestors.
As here the value of inbreeding co-efficient is aproximately 0 so we can conclude that
3. When a common ancestor is iself inbreed the inbreeding coefficient is = (1/2)n (1+ inbreeding
co-efficient of common ancestor) ,
The probability that a copy of gene in D makes the way to O = (1/2)7 = 0.00781
Therefore inbreeding co-efficient is = 0.00781 * (1 + 1/2 )=0.01172.

5. Cells with an intracellular osmolarity of 300mosmL are suspended.pdf
5. Cells with an intracellular osmolarity of 300mosm/L are suspended in the following solutions.
Describe the sequence of events that take place.
(a)0.3M urea (membrane permeable)
(b)0.3M glucose (membrane impermeable)
(c)0.6M urea
(d)0.6M glucose
Solution
Osmolarity of a solution refers to the concentration of the solution in terms of how strongly it
attracts water molecules across a semipermeable membrane. It is given the intracellular
osmolarity of the cell is 300 mosm/L. It can also be expressed as 0.3 osm/L or 0.3 M.
(a) 0.3 M Urea (membrane permeable)
This solution is isosmotic to the intracellular osmotic pressure. But, the cell membrane being
selectively permeable, allows the entry of urea until both the solutions become isotonic. This
leads to bursting ofcell as along with urea water enters the cell.
(b) 0.3 M Glucose (membrane impermeable)
This solution is also isosmotic to the intracellular osmotic pressure. But given that the membrane
is impermeable, glucose cannot enter to cell and an isotonic condition cannot be reached. Hence
the cell would be unstable and would distort due to the uneven tonicity.
(c) 0.6 M urea
This solution is hypertonic and hyperosmotic as compared to the cell\'s intracellular fluid. Thus,
water will move out through the pores of the cell membrane causing the cell to shrink or become
flaccid.
(d) 0.6 M glucose
This solution is hypertonic and hyperosmotic as compared to the cell\'s intracellular fluid. Thus,
water will move out through the pores of the cell membrane causing the cell to shrink or become
flaccid..

Which is true of the data shown in the histogram I. The distribution.pdf
Which is true of the data shown in the histogram? I. The distribution is approximately
symmetric. II. The mean and median are approximately equal. III. The median and IQR
summarize the data better than the mean and standard deviation. Click the icon to view the
histogram. I and III I, II and III I only I and II III only
Solution
(I) The data shows that the shape of this histogram is bell-shaped. Also,if a line is drawn down
the middle of the graph, the two sides will mirror each other. So,the distribution is approximately
symmetric.
(II) In the given histogram where the values of data occur at regular frequencies. So, the mean,
median and mode occur at the same point.
(III) The IQR is the difference between the third and the first quartile. IQR makes the values by
estimate of outliers where mean and standard deviation are not effected against outliers. So, the
median and IQR is not summarize the data well.
Answer is (I) and (II).

Identify the distinguishing characteristics of member of Phylum Cnid.pdf
Identify the distinguishing characteristics of member of Phylum Cnidaria, including symmetry,
number of embryonic tissue layers, unique structures, skeleton and polymorphism (polyp and
medusa), place Cnidaria on a cladogram
Compare and contrast how a general polyp and a medusa feed
Describe why a nerve net was such a major evolutionary adaptation
Describe the characteristics of the four classes of Cnidarians
Label the following on a drawing: tentacles, mouth, anus, gastrovascular cavity, cnidocytes,
nerve net
Solution
Answer1) Symmetry- Radially symmetrical body
Number of embryonic tissue layers- two (endoderm and ectoderm)
Unique structures- Stinging cells (Cnidocytes)
Skeleton- Hydrostatic skeleton
Polymorphism (polyp and medusa)- polyp is a flower like solitary form and medusa is a free-
floating miniature of cnidarians.
Answer 2) a tubular shaped body form is called as polyp. They are sessile and are found as
attached bottom (basal plate) to a solid surface with the opened mouth at the top. while medusa is
an umbrella or bell shape form, having their mouth facing downwards. And they are free
floating. Being a sessile, polyp filter their food from the water by their tiny-beating cilia. While
medusas are free floating and motile so they can trap their feedings, and need not to filter the
water all the time though these structures were more related to the sexual reproduction.
Answer 3) Nerve net is a diffused framework of neurons in the body which can transmit
signals/impulse in different directions from a single point of stimulus.
This became a major evolutionary adaptation because it allowed the organism to sense the
environmental stimulus from any region of its body and respond accordingly. This allowed the
readily development and motion of different body parts such as limb like structures.
Answer 4) These are the four classes of cnidarians.
Hydrozoa are diploblastic and multicellular animals. Which has only mouth opening. They have
a fixed polyp stage and the reproductive medusa stage. They have the gonads as well.
Scyphozoan are present in medusoid forms. They have tentaculocysts as Sense organs. They
have Velarium in endodermal canal (Acraspedote). They endodermal gonads.
Anthozoan are present only in polyp forms. Their medusa stage is absent. They have Mesenteries
which bear nematocyst. They also possess endodermal Gonads.
Cubozoan looks like the jelly fish and called as jelly boxes. They possess box shaped medusa
and they share typical characteristics of scyphozoans..
If most evolutionary change occurs during and immediately after spec.pdf
If most evolutionary change occurs during and immediately after speciation, could speciation
rates and extinction rates explain major patterns in macroevolution? In turn, what factors may
influence speciation and extinction rates (are they all biological, or can geological /
meteorological / astronomical factors also play a role)?
Solution
In the course of evolution, some mutations keep on occurring with every replicative step. These
mutations lead to differences in alleles, which further result in different genotypes. Some
genotypes have higher fitness while others have lower fitness. Natural selection selects the
phenotypes which have higher fitness, and slowly discards the others during the course of
evolution. So, extinction rate depends on fitness and natural selection.
As new phenotypes are selected, they result in formation of new species; the process is known as
speciation. Speciation further results in evolution. Higher the speciation rate, higher will be the
rate of evolution.
So, you can say that most evolutionary changes occur during and after speciation.
Overall the biological factors affecting speciation and extinction rates are:
It is important to note that that apart from the above two factors, geological/astronomical factors
also affect speciation, extinction and evolution. Changes in the earth since times immemorial
ultimately resulted in changes like:.
Imagine that someone picking up roses in a garden gets a scratch fro.pdf
Imagine that someone picking up roses in a garden gets a scratch from a thorn. Some bacteria
(Staphyloccocus aureus and Streptococcus pyogenes) take advantage of the wound to gain access
to the deeper layers of the skin and attempt to cause an infection. Describe the different stages of
the host response (in particular the types of cells and receptors involved) and how the bacteria
will be recognized and eliminated.
Solution
The superficial staphylococcal and streptococcal infections are very common in skin. The
physiological condition of the skin is much suitable to these bacteria. Both these bacteria are
potent toxin and enzyme producing strains.
S.auresus infection on the skin immediately stimulates the inflammatory response and
macrophages and neutrophils are proliferated at the site of infection. The organism can enter the
body through openings in the skin barrier like hair follicles and can cause infections like
folliculitis, pimples, furuncle which is type of abscess. The furuncles also damage the
neighboring tissue by invading deep in to the tissue. This is known as carbuncle. Staphylococci
cause a highly contagious skin infection in children known as impetigo. The impetigo is two
types-nonbullous impetigo is caused by both S.aureus and S.pyogenes; bullous impetigo is
caused by staphylococcal toxin. It is also known as staphylococcal scalded skin syndrome. At
later stages of toxic shock syndrome the scalded skin syndrome is the characteristic feature.
Streptococci also secrete toxin and enzymes. The toxins are called hemolysins that lyse the red
blood cells. Various hemolysins like alpha, beta and gamma are produced by various
streptococcus strains. S.pyogenes is an important beta hemolytic streptococcus. Streptococcus
skin infections are generally superficial but some times may reach the deeper tissues also.
S.pyogenes infects the dermis of the skin and also causes a disease known as erysipelas in which
the skin erupts in to reddish patches.
The skin scraping is cultured and stained to observe the bacteria under microscope.
Staphylococci and streptococci both are gram positive and round shaped bacteria. The
staphylococci occur as grape-like clusters (Staphylococci name indicates bunch of grapes in
Greek). The streptococci are arranged in chains or pairs. Topical antibiotics like Mupirocin and
oral antibiotics like first generation cephalosporins and erythromycin are used to eliminate the
bacteria..
I need help working out this question . woman has normal vision al.pdf
I need help working out this question .
woman has normal vision although her maternal grandfather (her mother’s father) had red-
green colorblindness, a sex-linked recessive trait. Her maternal grandmother and the woman’s
own father are assumed to not possess a copy of the mutant allele. The woman marries a man
with normal vision although his father was colorblind. What is the probability that the first child
of this couple will be colorblind?
Solution
As it is x linked inheritance, the genotype of women is either xx = Normal or xxc =Carrier for
disease. If she is carrier (xxc) and married normal man, then the probability of 1st chaild getting
colour blindness is 1/4 = 0.25
Color blind ness is x linked and it inherit criss cross manner. That mean, male transfer color
blindness to her female children and. female transfer her male children.
XXc x XY ----------------> XX, XY, XXc & XcY
XcY progeny is only colour blind. So probability is 1\\4.

How con osmosis work for and against homeostasis How do osmosis .pdf
How con osmosis work for and against homeostasis? How do osmosis and diffusion relate to
dialysis? (Short paragraph o fine)
Solution
Multi cellular organisms should maintain a balance between internal and external environments
to carry out proper metabolic activities. The maintenance of relatively stable environment
internally is known as homeostasis.
All the body functions carried out by various systems of the body contribute to the homeostasis
to maintain a stable environment in the body for its survival and function. Homeostasis is much
required and the vital force for the each cell and through performing specialized activity, each
cells maintain a stable internal environment.
The net diffusion of water down the concentration gradient through the selectively permeable
membrane is called osmosis..
Enzymes and KE. Whats the relationship in terms of substrate mo.pdf
Enzymes and KE. What\'s the relationship in terms of substrate molecules
Enzymes and KE. What\'s the relationship in terms of substrate molecules
Solution
ANS:
Enzyme KE(kinetic energy)and substrate molecules relationship:
When the temperature raises the kinetic energy of reactants is also raised, increasing in
temperature results in higher activation energy molecules and more molecular (enzyme and
substrate) collision and interaction for the reaction to proceed faster.
The enzymes present in the human body usually need 37.5 o C (optimal temperature). The
optimum temperature for most of the enzymes between 40-45o C.
In this condition rate is increased. Increasing substrate concentration means an increasing rate at
which the enzyme and substrate molecules encounter one another
In general, the enzymes are exposed to a temperature above 50 o C, denaturing leading to
derangement in native structure. Majority of enzymes became inactive at higher temperature
above 70 o C
In enzymes at higher temperatures intra and intermolecular bonds are broken down, so the
enzyme molecules gain even more kinetic energy.
After reaching the maximum point, the rate of the reaction suddenly fall down due to the enzyme
degradation..
Explain membranes. Include the definition and name the four types an.pdf
Explain membranes. Include the definition and name the four types and which tissues each type
contains.
Solution
Answer : Membranes are the flat sheets of pliable tissue that cover or line a part of the body. The
combination of an epithelial layer and an underlying connective tissue layer constitutes an
epithelial membranes. These includes,
Mucous membranes : These membranes lines the body cavity that opens directlyto the exterior.
Mucous membranes lines the entire digestive, respiratory and reproductive tracts and much of
the urinary tract.
Serous Membranes : A serous membrane or Serosa lines a body cavity that does not open
directly to the exterior and it covers the organs that lie within the cavity.serous membranes
consist of areolar connective tissue covered by mesothelium and also consists of two layers such
as Parietal and visceral layer.
Cutaneous Membrane : These membarnes covers the surface of the body and consists of a
superficial portion called the epidermis and a deeper portion called the dermis.
Synovial Membranes : Like serous membranes, synovial membranes line structures that do not
open to the exterior. They lack in epithelium and are composed of discontinuous layer of cells
called synoviocytes, which secretes synovial fluid. Synovial fluid lubricates and nourishes the
cartilage covering the bones at movable joints and contains macrophages that moves microbes
and debris from the joint cavity..

Clinical immunology questionMr. R.M., a 60-year-old Caucasian man,.pdf
Clinical immunology question
Mr. R.M., a 60-year-old Caucasian man, was stung by a bee while gardening. He had been stung
once before earlier in the summer. Within a few seconds, his hand began to itch and he began to
experience abdominal cramping. He subsequently began experiencing difficulty breathing.
Fortunately, he was able to reach a first aid kit in his garage. Inside of the kit was an EpiPen
(injectable epinephrine) that his wife kept for herself because she was allergic to bee venom. He
immediately had his wife drive him to the hospital.
He was asymptomatic on arrival at the hospital. R.M. had no history of adverse reactions to bee
venom or antibiotics. Because of the nature of the incident, a diagnosis of anaphylactic shock
due to bee venom sensitivity was made. An IgE level was ordered. The results indicated a level
more than twice the (normal) reference range value. In addition, a follow-up skin test was
performed. The patient was extremely positive for bee venom.
Questions:
1.Which of the 4 types of hypersensitivity reactions does this case represent?
2.What is the immunologic mechanism involved in anaphylaxis?
3.What types of agents can induce anaphylactic shock?
4.Describe 2 different types of testing to diagnosis this patient.
5.What is the risk in performing a skin test?
Solution
Answer:
1) There are four types of hypersensitivity reactions, they include:
1) Type - I ; Allergy , 2) Type- II ; Cytotoxic, antibody-dependent, 3) Type III; Immune
complex disease
4) Type IV; Delayed-type hypersensitivity.
2) Anaphylaxis is an Type-I reaction ; allergic reaction. During allergic reaction, IgE react with
antigen, and it activates basophils and mast cells, due this activation, histamines are released.
3) Anaphylactic shock could be due to the food agents such as milk, eggs and shellfish. In few
cases, insect stings can cause shock.
4) Diagnosis includes, 1) Allergy testing (skin allergy test), 2)Differential diagnosis.
5) Skin test is available only to test effect of penicillin drug allergy.so, it is risk for allergies..
As shown in the pedigree below, a pair of first cousins (I and K) ma.pdf
As shown in the pedigree below, a pair of first cousins (I and K) marry an unrelated pair of first
cousins (J and L). Their children M and N produce child O.
1. Calculate the inbreeding coefficient (f) of O (express answers to 1 and 3 to three decimal
places). Assume that f= 0 for all ancestors. (Hint: To help you out, I have shaded individuals
who cannot contribute to autozygosity.) To show your work, use the letter names to indicate each
path/loop that contributes to autozygosity. For example: path 1 = M-I-E…
2. Interpret your result. What does this value of f indicate?
3. Recalculate f for child O when f=1/2 for great-great grandmother D (f=0 for all other
ancestors). Hint: After you have calculated all the loops above, you’ll adjust just the loop that
includes ancester D to account for her ancestral inbreeding using the formula presented in class
(and text). As shown in the pedigree below, a pair of first cousins (I and K marry a unrelated pair
of first cousin s and L). Their children M and N produce child O. 1. Calculate the inbreeding
coefficient (f) of O (express answers to 1 and 3 to three decimal places). Assume that f 0 for all
ancestors. (Hint: To help you out, I have shaded individuals who cannot contribute to
autozyBosity.) o show your work, use the letter names to indicate each path/loop that contributes
to autoz osit For example: path 1 M-1-E 2. Interpret your result. What does this value of
findicate? 3. Recalculate f for child o when f-1/2 for great-great grandmother D (f 0 for all other
ancestors). Hint: After you have calculated all the loops above, you\'ll adjust just the loop that
includes ancester D to account for her ancestral breeding using the formula presented in class
(and text)
Solution
1. Path 1:
So, the probability that a copy of gene in A makes the way down to O via E and a copy of gene
in B makes the way down to O via F =( ½)n = (½)7=0.00781. Here n= node=7
Path 2:
Similarly like the first one the total probability in path 2 will be same that is 0.00781.
Thus inbreeding co-efficient = 0.00781+0.00781=0.01562.
2. Generally, the higher the level of inbreeding closer the coefficient of relationship approaches a
value of 1 and approaches a value of 0 for individuals with remote common ancestors.
As here the value of inbreeding co-efficient is aproximately 0 so we can conclude that
3. When a common ancestor is iself inbreed the inbreeding coefficient is = (1/2)n (1+ inbreeding
co-efficient of common ancestor) ,
The probability that a copy of gene in D makes the way to O = (1/2)7 = 0.00781
Therefore inbreeding co-efficient is = 0.00781 * (1 + 1/2 )=0.01172.

5. Cells with an intracellular osmolarity of 300mosmL are suspended.pdf
5. Cells with an intracellular osmolarity of 300mosm/L are suspended in the following solutions.
Describe the sequence of events that take place.
(a)0.3M urea (membrane permeable)
(b)0.3M glucose (membrane impermeable)
(c)0.6M urea
(d)0.6M glucose
Solution
Osmolarity of a solution refers to the concentration of the solution in terms of how strongly it
attracts water molecules across a semipermeable membrane. It is given the intracellular
osmolarity of the cell is 300 mosm/L. It can also be expressed as 0.3 osm/L or 0.3 M.
(a) 0.3 M Urea (membrane permeable)
This solution is isosmotic to the intracellular osmotic pressure. But, the cell membrane being
selectively permeable, allows the entry of urea until both the solutions become isotonic. This
leads to bursting ofcell as along with urea water enters the cell.
(b) 0.3 M Glucose (membrane impermeable)
This solution is also isosmotic to the intracellular osmotic pressure. But given that the membrane
is impermeable, glucose cannot enter to cell and an isotonic condition cannot be reached. Hence
the cell would be unstable and would distort due to the uneven tonicity.
(c) 0.6 M urea
This solution is hypertonic and hyperosmotic as compared to the cell\'s intracellular fluid. Thus,
water will move out through the pores of the cell membrane causing the cell to shrink or become
flaccid.
(d) 0.6 M glucose
This solution is hypertonic and hyperosmotic as compared to the cell\'s intracellular fluid. Thus,
water will move out through the pores of the cell membrane causing the cell to shrink or become
flaccid..

inflamed area..
Which is true of the data shown in the histogram I. The distribution.pdf
Which is true of the data shown in the histogram? I. The distribution is approximately
symmetric. II. The mean and median are approximately equal. III. The median and IQR
summarize the data better than the mean and standard deviation. Click the icon to view the
histogram. I and III I, II and III I only I and II III only
Solution
(I) The data shows that the shape of this histogram is bell-shaped. Also,if a line is drawn down
the middle of the graph, the two sides will mirror each other. So,the distribution is approximately
symmetric.
(II) In the given histogram where the values of data occur at regular frequencies. So, the mean,
median and mode occur at the same point.
(III) The IQR is the difference between the third and the first quartile. IQR makes the values by
estimate of outliers where mean and standard deviation are not effected against outliers. So, the
median and IQR is not summarize the data well.
Answer is (I) and (II).
