Rana Issa is a college student from Egypt, who is majoring in Agricultural Engineering. Since as
long as she can remember, she had a deep interest in food production and food sustainability. She
grew up in a poor household and could recall days where she barely had enough to eat. For her
summer vacation, she decided to travel to a small factory farm in Saudi Arabia to learn more
about livestock management. Once she arrived, a man named Rizwan Kassis greeted her and
showed her around the farm. They had many animals on the farm. Some were raised for their
meat, and others such a camels were raised to be used in labor and transport. Rizwan talked
about how he hated the way large livestock farms operated, how unsustainable those practices
were, and how much better his farm was. Rana learned a lot from Rizwan, but she was tired from
the day and asked Rizwan if they could rest for the night. She awoke in the middle of the night
and felt something biting at her leg. She looked down and saw that it was just a tick. Rana
grabbed her tweezers out of her backpack and carefully removed the tick. She cleansed the site
with some soap and water and then went back to sleep. The next few days, Rana learned more
about Rizwan’s farm and even helped out with the day to day task. On the third day, she was
feeling tired and started to have a slight fever. Her fever worsen in the night, and she experienced
vomiting and diarrhea. The next day she was rushed to the hospital because she was bleeding
out. Luckily she received treatment as soon as possible and made a speedy recovery.
Case Study Questions:
The doctors found that Rana suffered from a rare disease that emerged in Saudi Arabia. Based on
this information and Rana’s symptoms,
1 what disease did Rana get on her trip, and what pathogen causes this disease?2
2How was Rana infected with this disease?
3Describe the pathogen that is responsible for the disease.
4What are the vectors of this disease?
5How is this disease treated and are there any ways to prevent the disease?
Solution

Prepare a two to three page report titled Environmental Sustainabi.pdf
Prepare a two to three page report titled \"Environmental Sustainability in the European Union
(EU).\" The report should be based on the publicly available information that you obtained. You
may use the report published by the European Commission.
Solution
The United Nations (UN) Conference on Environment and Development held in Rio de Janeiro
in 1992, Eurostat started working closely with the UN Commission on Sustainable Development
on global indicators of sustainable development. Sustainable development policy aims to achieve
a continuous improvement in citizens’ quality of life and wellbeing. This involves the pursuit of
economic progress while safeguarding the natural environment and promoting social justice. The
economic, environmental and social dimensions are all part of the EU Sustainable Development
Strategy adopted in 2001 and renewed in 2006 . The weak economic activity in the short term
has reduced some pressure on the environment, but overall progress is mixed regarding the
environmental dimension of sustainable development, the headline indicators show mixed
results. Environmental indicators linked to economic performance have developed favorably in
the short term, but this is mainly due to reduced economic activity. This is evident in the
reduction of greenhouse gas emissions and energy consumption. Despite some mildly positive
long-term developments, the pressure on natural resources has increased in the short term.
Clearly favourable developments have been observed for one of the two headline indicators of
the climate change and energy theme. Greenhouse gas emissions have steadily decreased in the
long run. If this trend continues, the EU is likely to surpass its Europe 2020 target of reducing
emissions by 20 % compared with 1990 levels. In 2012, the EU was only two percentage points
away from its target. The economic recovery could therefore increase GHG emissions in the
coming years. Energy consumption of transport relative to GDP has followed a moderately
unfavorable long-term trend but a clearly favorable short-term trend. The indicator has fallen
more or less continuously since 2000, which does not necessarily reflect better environmental
outcomes.
For some of the indicators the issue of interest of two trends is usually an economic variable and
the environmental variable that shows the environmental pressures exerted by the economic
activity. These are called decoupling indicators because they show the strength of the link
between the economic and the environmental variable. In relation to sustainable development,
the aim is to achieve a decoupling of these two variables, so that continued economic growth
does not lead to a further increase in environmental degradation. The evaluation is considered
favourable if the environmental pressure variable is decreasing and unfavourable if it is
increasing. Depending on the direction and magnitude of change in the pressure variable in
relation to the driving force, there are fou.

Header file I_Life.h Rules The universe of the Game of Life is an infinite two-dimensional
orthogonal grid of square cells, each of which is in one of two possible states, alive or dead.
Every cell interacts with its eight neighbors, which are the cells that are horizontally, vertically,
or diagonally adjacent. At each step in time, the following transitions occur: 1. Any live cell
with fewer than two live neighbors dies, as if caused by under-population. 2. Any live cell with
two or three live neighbors lives on to the next generation. 3. Any live cell with more than three
live neighbors dies, as if by over-population. 4. Any dead cell with exactly three live neighbors
becomes a live cell, as if by reproduction. The initial pattern constitutes the seed of the system.
The first generation is created by applying the above rules simultaneously to every cell in the
seed—births and deaths occur simultaneously, and the discrete moment at which this happens is
sometimes called a tick (in other words, each generation is a pure function of the preceding one).
The rules continue to be applied repeatedly to create further generations. (Wikipidia Oct. 5th

In which component of an HVAC system does a chilled beam save energy.pdf
In which component of an HVAC system does a chilled beam save energy?
Solution
A chilled beam is a type of convection HVAC system designed to heat or cool large buildings.
Pipes of water are passed through a \"beam\" (a heat exchanger) either integrated into standard
suspended ceiling systems or suspended a short distance from the ceiling of a room. As the beam
chills the air around it, the air becomes denser and falls to the floor. It is replaced by warmer air
moving up from below, causing a constant flow of convection and cooling the room. Heating
works in much the same fashion, similar to asteam radiator. There are two types of chilled
beams. Some passive types rely solely on convection whilst there is a \"Radiant\"/convective
passive type which cools through a combination of radiant exchange (40%) and convection
(60%) which can provide higher thermal comfort levels, while the active type (also called an
\"induction diffuser\")[8] uses the momentum of ventilation air entering at relatively high
velocity to \"induce\" circulation of room air through the unit (thus increasing its heating and
cooling capacity).
The chilled beam is distinguishable from the chilled ceiling.The chilled ceiling uses water
flowing through pipes like a chilled beam does; however, the pipes in a chilled ceiling lie behind
metal ceiling plates, and the heated or cooled plates are the cause of convection and not the pipe
unit itself Chilled beams are about 85 percent more effective at convection than chilled ceilings.
The chilled ceiling must cover a relatively large ceiling area because it provides heating and
cooling mainly by radiant, rather than convective, heat transfe.
If you deposit money today in an account that pays 4.5 annual inter.pdf
If you deposit money today in an account that pays 4.5% annual interest, how long will it take to
double your money? Round your answer to two decimal places.
Solution
We use the formula:
A=P(1+r/100)^n
where
A=future value($2x)
P=present value($x say)
r=rate of interest
n=time period.
2x=x(1+4.5/100)^n
2=(1.045)^n
Taking log on both sides;
log 2=n*log(1.045)
n=log 2/log(1.045)
=15.75 years(Approx)..

Solution
cot^2 theta=(3/2)csc theta
cot theta=cos theta/sin theta
and csc theta=1/sin theta
cos^2 theta/sin^2 theta= (3/2sin theta)
2 cos ^2 theta= 3sin theta
and cos^2 theta= 1- sin^2 theta
2(1-sin^2 theta)= 3 sin theta
2-2sin^2 theta= 3sin theta
2sin^2 theta -3sin theta -2=0
(sin theta -2)(2sin theta +1)=0
sin theta=2 and sin theta=-1/2
we have to ignore sin theta=2 since sin theta lies between -1 and 1
therefore sin theta=-1/2
theta= 7pi/ 6 , 11pi/6.
how can second messengers amplify a signal initiated by a toxicant o.pdf
how can second messengers amplify a signal initiated by a toxicant or drug?
Solution
A toxicant or a drug can be considered as the first messenger.When these messengers bind to
their respective receptors,they may not always be able to pass through the phospholipid bilayer
of the plasma membrane to enter the cell and initiate the signalling process.In such cases,
secondary messengers helps to relay the signals from the recepors into the cell and in doing so,
they also amplify the signal received.This amplification of a signal is brought about by activating
many multi-cyclic kinase cascades and many intracellular signalling processes at a time.Thus for
one every receptor that is bound by a drug /toxicant, the signal is amplified many times..
Examine the following table of characters in four different species o.pdf
Examine the following table of characters in four different species of flower. Based on the
character matrix, which is MOST likely an ancestral trait for the group of species? presence of
sepals arrangement of petals number of petals number of carpals
Solution
The different types of species should have the common type of traits is know as ancestral trait. It
also has a genetic similarities like dogs, horses, donkey all have 4 legs they all arise from
common ancestors.
In this case, only arrangement of petals follows the ancestral trait because all the 4 species has
the genetic similarities and common traits is whorled.
Other traits like number of carples and petals having different numbers in different species so,
they are not a ancestral traits..

describe the mutualistic relationship between trichonymphs, termite,.pdf
describe the mutualistic relationship between trichonymphs, termite, and bacteria.
Solution
Trichonympha live in the gut of a termite and enable the termite to survive. As termites eat
wood. But they are unable to digest cellulose, which is major component in the wood. The
Trichonympha that live in the termite\'s gut feed on this cellulose. If not present then termites
would die of starvation. The Trichonympha in this way feed themselves.
Termites learned that a bacterium in their gut could help them break down the cellulose and
plant fibers that they eat ..

Solution
Ans:
Compare and contrast how the nervous and endocrine systems control body function, with
emphasis on the mechanisms by which the controlling signals are transferred through the body
and the time course of the response(s) and action(s).
The nervous and endocrine systems differ in their means of communication.
Nervous system: Electrical and chemical communication. Fast. Stops when stimulus ceases.
Neurons quickly adapt and their reponses decline.
Endocrine system: Chemical. Slow. Trickle-down effect. Persistent responses.
Describe the structure of each type of hormone, explain how it is created, give an example and
explain how that type is transported in the body, and how it generally works in cells.
Amines – Monoamines synthesized from amino acids by the removal of COOH group, and retain
a nitrogen (epinepherine, norepinephrine, dopamine, histamine, serotonin.). Hydrophilic, mixes
with blood plasma. Monoamines (thyroid hormone): acts on nuclear receptors. Enters target cells
thru ATP dependent transport proteins.
Peptide hormones - (chains of 3-200+ amino chains) and Hydrophilic, mixes with blood plasma.
Peptides and catecholamines: hydrophilic, stimulates tatrget indirectly. Binds to cell surface
receptors, linked to second messenger systems, such as cAMP (cyclic adenosine
monophosphate).
Steroid hormones- derived from cholesterol. They are hydrophobic, binds to hydrophilic
transport proteins (albumins and globulins synthesized by the liver, and prolongs half-lives.).
The receptor associates with the target gene, controls transcription. (estrogen and progesterone
are good examples of steroid hormone actions).
Predict the action of a hormone based on the stimuli that release the hormone and the class of
hormone.The stimuli causing endocrine glands to secrete their hormones in direct response to
changing blood levels of certain critical ions and nutrients are called hormonal stimuli.
Releasing hormone: any of several hormones produced in the hypothalamus and carried by a
vein to the anterior pituitary gland where they stimulate the release of anterior pituit.
Answer 1 and 2 in detail Recently, Kathy Smith, a project manager fo.pdf
Answer 1 and 2 in detail Recently, Kathy Smith, a project manager for a large industrial
construction organization, was assigned to oversee a multimillion-dollar chemical plant
construction project in Southeast Asia. Kathy had earned this assignment after completing a
number of smaller construction assignments in North America over the past three years. This
was her first overseas assignment and she was eager to make a good impression, particularly
given the size and scope of the project. Successfully completing this project would increase her
visibility within the organization dramatically and earmark her as a candidate for upper
management. Kathy had good project management skills; in particular, she was organized and
highly self-motivated. Team members at her last two project assignments used to joke that just
trying to keep up with her was a full-time job.
Solution
1) Kathy lacks various characteristics of emotional intelligence including empathy, self-
awareness, and social skills. To complete the deadlines of the project Kathy forced her team
members to work on the weekends. She failed to understand the requirements of people from
varying cultural backgrounds. She used the similar approach of project management that she
used to adopt in her home country. Furthermore, Kathy lacked sufficient communication skills
that resulted in misunderstandings and conflict among her team members.
2) Out of five different dimensions of emotional intelligence, Kathy lacked social skills and
empathy element the most. She failed to understand the requirements and feelings of workers.
She forced the workers to work on the weekends. It led to the dissatisfaction and passiveness of
the workers. Besides this, she also failed to understand the cultural difference among people
from different backgrounds.

move. b) Explain your reasoning for your answrr abeve in a lew sentences Include in your
answer the fundamental idea behind why some electrons can move when a voltage is applied and
why some cannot
Solution
a) The answer is (iv)
The material is a semiconductor in the light.
When hooked to a battery some electrons in the lower band will not move.
When hooked to a battery some electrons in the upper band will move.
b) As is seen in the above figure, there are two bands with an energy gap in between. The lower
band (called valence) is alomst filled with few available states. The upper band (conduction
band) is partiallty filled. This represents a semiconductor which is light. The photon energy has
cause some electrons from the valence band to be excited into the conduction band. For a metal,
the conduction and valence band overlap. For an insulator the energy gap is huge and electrons
from the valence band cannot be excited into the conduction band. Hence the energy band
diagram represents a semiconductor in light. Note that in dark, the electrons do not have enough
energy to cross the band gap and go into the conduction band.
When hooked to a battery the electrons in the lower band do not move. This is beacuse they are
tightly bound to the nucleus of the atom.
The electrons in the conduction band however are free electrons and are free to move. Hence
when hooked to a battery, the electrons drift due to the applied electric field..

Briefly Description 4 application and 4 Mechanism that is used on a .pdf
Briefly Description 4 application and 4 Mechanism that is used on a steamboat? And how do
these applications and Mechanism is applied on a steamboat?
Solution
Mechanism:
Marine steam engine
A marine steam engine is a steam engine that is used to power a ship or boat.
Propeller
A propeller is a type of fan that transmits power by converting rotational motion into thrust.
Paddle steamer
A paddle steamer is a steamship or riverboat powered by a steam engine that drives paddle
wheels to propel the craft through the water.
boiler
The boiler holds a quantity of water in such a way that most of the heat from the fire can be
transferred to the water. The water boils and gives off steam under pressure, so the boiler has the
double purpose of transferring heat and containing pressure. The greater the surface area exposed
to the fire, the more heat can be transferred to the water ( and the less wasted up the stack ), and
the more steam produced. The best way to create this large surface area in a small space is to fill
the space with pipes, or tubes. Therefore the heating surface of all steamboat boilers is made up
primarily of tubes..

1. explain how the structures of simple squamous, cuboidal and cilia.pdf
1. explain how the structures of simple squamous, cuboidal and ciliated and non-ciliated
columnar epithelium are related to their functions
2. outline the taxonomic scheme, describe four classical and four molecular methods used in
phylogeny
Solution
1).
The epithelial tissues form the sheet like outer covering of the body surfaces and provide
protection to the organs. One surface of this epithelial tissue is not bound to anything and
produces glandular secretions, also involved in absorption process.
The classification of epithelial tissue based upon their shape is given below:
1). Squamous epithelial cells: Thin layer of flattened cells
2). Cuboidal epithelial cells: Cube like shape
3). Columnar epithelial cells: Elongated shape
4). Simple epithelium: Single layer of cells
5). Stratified epithelial cells: Two or more than two layers of cells
The structure and function of some of the epithelial tissue is given below:
Type of tissue
Structure
Function
1). Simple squamous
Single layer of thin, flatten cells tightly packed with one another. The nuclei are broad and thin.
Lines the inside of capillaries of blood vessels and alveoli. Allows the diffusion and filtration of
molecules such as gaseous exchange in the alveoli.
2). Simple cuboidal
Single layer of cube shaped cells. The nuclei are centrally located and spherical shape.
Covers ovaries, glands, linings of kidney tubules. Allow the tubular secretion and tubular
reabsorption in the kidneys, secretion of glandular products in the glands.
3). Simple columnar
Single layer of elongated cells, nuclei are located near the basement membrane. Some of them
are ciliated, and some are non-ciliated. The length of cilia ranges from 7 to 10 µm in length.
Linings of digestive organs and uterine tubes. Cilia allows the expulsion mucus, movement of
egg cell to the uterus.
4). Stratified columnar
Multiple layers of cube shaped cells (usually, 2 to 3 layers)
Lines the urethra, pharynx, ducts of exocrine glands.
5). Pseudostratified columnar
Multiple layers of cells. The superficial layer is of elongated cells, and the deeper layer layers are
cuboidal.
Cover the air ways of the respiratory system. The goblet cells secrete mucus and the cilia of these
cells sweep the mucus.

In which component of an HVAC system does a chilled beam save energy.pdf
In which component of an HVAC system does a chilled beam save energy?
Solution
A chilled beam is a type of convection HVAC system designed to heat or cool large buildings.
Pipes of water are passed through a \"beam\" (a heat exchanger) either integrated into standard
suspended ceiling systems or suspended a short distance from the ceiling of a room. As the beam
chills the air around it, the air becomes denser and falls to the floor. It is replaced by warmer air
moving up from below, causing a constant flow of convection and cooling the room. Heating
works in much the same fashion, similar to asteam radiator. There are two types of chilled
beams. Some passive types rely solely on convection whilst there is a \"Radiant\"/convective
passive type which cools through a combination of radiant exchange (40%) and convection
(60%) which can provide higher thermal comfort levels, while the active type (also called an
\"induction diffuser\")[8] uses the momentum of ventilation air entering at relatively high
velocity to \"induce\" circulation of room air through the unit (thus increasing its heating and
cooling capacity).
The chilled beam is distinguishable from the chilled ceiling.The chilled ceiling uses water
flowing through pipes like a chilled beam does; however, the pipes in a chilled ceiling lie behind
metal ceiling plates, and the heated or cooled plates are the cause of convection and not the pipe
unit itself Chilled beams are about 85 percent more effective at convection than chilled ceilings.
The chilled ceiling must cover a relatively large ceiling area because it provides heating and
cooling mainly by radiant, rather than convective, heat transfe.
If you deposit money today in an account that pays 4.5 annual inter.pdf
If you deposit money today in an account that pays 4.5% annual interest, how long will it take to
double your money? Round your answer to two decimal places.
Solution
We use the formula:
A=P(1+r/100)^n
where
A=future value($2x)
P=present value($x say)
r=rate of interest
n=time period.
2x=x(1+4.5/100)^n
2=(1.045)^n
Taking log on both sides;

HINT: Eventually you will need to factor. Just before factoring, try multiplying both sides of the
equation by 2 to get rid of the fraction.
Solution
cot^2 theta=(3/2)csc theta
cot theta=cos theta/sin theta
and csc theta=1/sin theta
cos^2 theta/sin^2 theta= (3/2sin theta)
2 cos ^2 theta= 3sin theta
and cos^2 theta= 1- sin^2 theta
2(1-sin^2 theta)= 3 sin theta
2-2sin^2 theta= 3sin theta
2sin^2 theta -3sin theta -2=0
(sin theta -2)(2sin theta +1)=0
sin theta=2 and sin theta=-1/2
we have to ignore sin theta=2 since sin theta lies between -1 and 1
therefore sin theta=-1/2
theta= 7pi/ 6 , 11pi/6.
how can second messengers amplify a signal initiated by a toxicant o.pdf
how can second messengers amplify a signal initiated by a toxicant or drug?
Solution
A toxicant or a drug can be considered as the first messenger.When these messengers bind to
their respective receptors,they may not always be able to pass through the phospholipid bilayer
of the plasma membrane to enter the cell and initiate the signalling process.In such cases,
secondary messengers helps to relay the signals from the recepors into the cell and in doing so,
they also amplify the signal received.This amplification of a signal is brought about by activating
many multi-cyclic kinase cascades and many intracellular signalling processes at a time.Thus for
one every receptor that is bound by a drug /toxicant, the signal is amplified many times..
Examine the following table of characters in four different species o.pdf
Examine the following table of characters in four different species of flower. Based on the
character matrix, which is MOST likely an ancestral trait for the group of species? presence of
sepals arrangement of petals number of petals number of carpals
Solution
The different types of species should have the common type of traits is know as ancestral trait. It
also has a genetic similarities like dogs, horses, donkey all have 4 legs they all arise from
common ancestors.
In this case, only arrangement of petals follows the ancestral trait because all the 4 species has
the genetic similarities and common traits is whorled.
Other traits like number of carples and petals having different numbers in different species so,
they are not a ancestral traits..

describe the mutualistic relationship between trichonymphs, termite,.pdf
describe the mutualistic relationship between trichonymphs, termite, and bacteria.
Solution
Trichonympha live in the gut of a termite and enable the termite to survive. As termites eat
wood. But they are unable to digest cellulose, which is major component in the wood. The
Trichonympha that live in the termite\'s gut feed on this cellulose. If not present then termites
would die of starvation. The Trichonympha in this way feed themselves.
Termites learned that a bacterium in their gut could help them break down the cellulose and
plant fibers that they eat ..

Solution
Ans:
Compare and contrast how the nervous and endocrine systems control body function, with
emphasis on the mechanisms by which the controlling signals are transferred through the body
and the time course of the response(s) and action(s).
The nervous and endocrine systems differ in their means of communication.
Nervous system: Electrical and chemical communication. Fast. Stops when stimulus ceases.
Neurons quickly adapt and their reponses decline.
Endocrine system: Chemical. Slow. Trickle-down effect. Persistent responses.
Describe the structure of each type of hormone, explain how it is created, give an example and
explain how that type is transported in the body, and how it generally works in cells.
Amines – Monoamines synthesized from amino acids by the removal of COOH group, and retain
a nitrogen (epinepherine, norepinephrine, dopamine, histamine, serotonin.). Hydrophilic, mixes
with blood plasma. Monoamines (thyroid hormone): acts on nuclear receptors. Enters target cells
thru ATP dependent transport proteins.
Peptide hormones - (chains of 3-200+ amino chains) and Hydrophilic, mixes with blood plasma.
Peptides and catecholamines: hydrophilic, stimulates tatrget indirectly. Binds to cell surface
receptors, linked to second messenger systems, such as cAMP (cyclic adenosine
monophosphate).
Steroid hormones- derived from cholesterol. They are hydrophobic, binds to hydrophilic
transport proteins (albumins and globulins synthesized by the liver, and prolongs half-lives.).
The receptor associates with the target gene, controls transcription. (estrogen and progesterone
are good examples of steroid hormone actions).
Predict the action of a hormone based on the stimuli that release the hormone and the class of
hormone.The stimuli causing endocrine glands to secrete their hormones in direct response to
changing blood levels of certain critical ions and nutrients are called hormonal stimuli.
Releasing hormone: any of several hormones produced in the hypothalamus and carried by a
vein to the anterior pituitary gland where they stimulate the release of anterior pituit.
Answer 1 and 2 in detail Recently, Kathy Smith, a project manager fo.pdf
Answer 1 and 2 in detail Recently, Kathy Smith, a project manager for a large industrial
construction organization, was assigned to oversee a multimillion-dollar chemical plant
construction project in Southeast Asia. Kathy had earned this assignment after completing a
number of smaller construction assignments in North America over the past three years. This
was her first overseas assignment and she was eager to make a good impression, particularly
given the size and scope of the project. Successfully completing this project would increase her
visibility within the organization dramatically and earmark her as a candidate for upper
management. Kathy had good project management skills; in particular, she was organized and
highly self-motivated. Team members at her last two project assignments used to joke that just
trying to keep up with her was a full-time job.
Solution
1) Kathy lacks various characteristics of emotional intelligence including empathy, self-
awareness, and social skills. To complete the deadlines of the project Kathy forced her team
members to work on the weekends. She failed to understand the requirements of people from
varying cultural backgrounds. She used the similar approach of project management that she
used to adopt in her home country. Furthermore, Kathy lacked sufficient communication skills
that resulted in misunderstandings and conflict among her team members.
2) Out of five different dimensions of emotional intelligence, Kathy lacked social skills and
empathy element the most. She failed to understand the requirements and feelings of workers.
She forced the workers to work on the weekends. It led to the dissatisfaction and passiveness of
the workers. Besides this, she also failed to understand the cultural difference among people
from different backgrounds.

move. b) Explain your reasoning for your answrr abeve in a lew sentences Include in your
answer the fundamental idea behind why some electrons can move when a voltage is applied and
why some cannot
Solution
a) The answer is (iv)
The material is a semiconductor in the light.
When hooked to a battery some electrons in the lower band will not move.
When hooked to a battery some electrons in the upper band will move.
b) As is seen in the above figure, there are two bands with an energy gap in between. The lower
band (called valence) is alomst filled with few available states. The upper band (conduction
band) is partiallty filled. This represents a semiconductor which is light. The photon energy has
cause some electrons from the valence band to be excited into the conduction band. For a metal,
the conduction and valence band overlap. For an insulator the energy gap is huge and electrons
from the valence band cannot be excited into the conduction band. Hence the energy band
diagram represents a semiconductor in light. Note that in dark, the electrons do not have enough
energy to cross the band gap and go into the conduction band.
When hooked to a battery the electrons in the lower band do not move. This is beacuse they are
tightly bound to the nucleus of the atom.
The electrons in the conduction band however are free electrons and are free to move. Hence
when hooked to a battery, the electrons drift due to the applied electric field..

Briefly Description 4 application and 4 Mechanism that is used on a steamboat? And how do
these applications and Mechanism is applied on a steamboat?
Solution
Mechanism:
Marine steam engine
A marine steam engine is a steam engine that is used to power a ship or boat.
Propeller
A propeller is a type of fan that transmits power by converting rotational motion into thrust.
Paddle steamer
A paddle steamer is a steamship or riverboat powered by a steam engine that drives paddle
wheels to propel the craft through the water.
boiler
The boiler holds a quantity of water in such a way that most of the heat from the fire can be
transferred to the water. The water boils and gives off steam under pressure, so the boiler has the
double purpose of transferring heat and containing pressure. The greater the surface area exposed
to the fire, the more heat can be transferred to the water ( and the less wasted up the stack ), and
the more steam produced. The best way to create this large surface area in a small space is to fill
the space with pipes, or tubes. Therefore the heating surface of all steamboat boilers is made up
primarily of tubes..

1. explain how the structures of simple squamous, cuboidal and ciliated and non-ciliated
columnar epithelium are related to their functions
2. outline the taxonomic scheme, describe four classical and four molecular methods used in
phylogeny
Solution
1).
The epithelial tissues form the sheet like outer covering of the body surfaces and provide
protection to the organs. One surface of this epithelial tissue is not bound to anything and
produces glandular secretions, also involved in absorption process.
The classification of epithelial tissue based upon their shape is given below:
1). Squamous epithelial cells: Thin layer of flattened cells
2). Cuboidal epithelial cells: Cube like shape
3). Columnar epithelial cells: Elongated shape
4). Simple epithelium: Single layer of cells
5). Stratified epithelial cells: Two or more than two layers of cells
The structure and function of some of the epithelial tissue is given below:
Type of tissue
Structure
Function
1). Simple squamous
Single layer of thin, flatten cells tightly packed with one another. The nuclei are broad and thin.
Lines the inside of capillaries of blood vessels and alveoli. Allows the diffusion and filtration of
molecules such as gaseous exchange in the alveoli.
2). Simple cuboidal
Single layer of cube shaped cells. The nuclei are centrally located and spherical shape.
Covers ovaries, glands, linings of kidney tubules. Allow the tubular secretion and tubular
reabsorption in the kidneys, secretion of glandular products in the glands.
3). Simple columnar
Single layer of elongated cells, nuclei are located near the basement membrane. Some of them
are ciliated, and some are non-ciliated. The length of cilia ranges from 7 to 10 µm in length.
Linings of digestive organs and uterine tubes. Cilia allows the expulsion mucus, movement of
egg cell to the uterus.
4). Stratified columnar
Multiple layers of cube shaped cells (usually, 2 to 3 layers)
Lines the urethra, pharynx, ducts of exocrine glands.
5). Pseudostratified columnar
Multiple layers of cells. The superficial layer is of elongated cells, and the deeper layer layers are
cuboidal.
Cover the air ways of the respiratory system. The goblet cells secrete mucus and the cilia of these
cells sweep the mucus.
