Tissue Definition
Tissues are groups of cells that have a similar structure and act together to perform a specific function. The word tissue comes from a form of an old French verb meaning “to weave”. There are four different types of tissues in animals: connective, muscle, nervous, and epithelial. In plants, tissues are divided into three types: vascular, ground, and epidermal. Groups of tissues make up organs in the body such as the brain and heart.
Types of Animal Tissues
Connective
Connective tissue connects or separates groups of other tissues. It is found in between all the other tissues and organs in the body. Connective tissue is made up of cells and ground substance, which is a gel that surrounds cells. Most connective tissue, except for lymph and blood, also contains fibers, which are long, narrow proteins. Fibers can be collagenous, which bind bones to tissues; elastic, which allow organs like the lungs to move; or reticular, which provide physical support to cells. Connective tissue also allows oxygen to diffuse from blood vessels into cells.
About 1 in 10 people are have a disorder involving connective tissue. Some connective tissue disorders include sarcomas, Marfan syndrome, lupus, and scurvy, which is a Vitamin C deficiency that leads to fragile connective tissue.
Muscle
Muscle tissue comprises all the muscles in the body, and the specialized nature of the tissue is what allows muscles to contract. There are three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle. Skeletal muscle anchors tendons to bones and allows the body to move. Cardiac muscle is found in the heart and contracts to pump blood. Smooth muscle is found in the intestines, where it helps move food through the digestive tract, and it is also found in other organs like blood vessels, the uterus, and the bladder. Skeletal and cardiac muscles are striated; this means that they contain sarcomeres (a unit of muscle tissue) that are arranged in a uniform pattern. Smooth muscle does not have sarcomeres.
Duchenne muscular dystrophy is an example of a muscle tissue disorder. It is an inherited disorder that causes muscles to atrophy over time. The muscles shorten as they atrophy, which can cause scoliosis and immobile joints. Individuals with the disorder are usually male because the gene responsible for it is found on the X chromosome (of which males have only one).
Nervous
Nervous tissue is found in the brain, spinal cord, and peripheral nerves, which are all parts of the nervous system. It is made up of neurons, which are nerve cells, and neuroglia, which are cells that help nerve impulses travel. Nervous tissue is grouped into four types: gray matter and white matter in the brain, and nerves and ganglia in the peripheral nervous system. The main difference between gray and white matter is that axons of the neurons in gray matter are unmyelinated, while white matter is myelinated. Myelin is a white, fatty substance that insulates neurons and

simple squamous epithelium is a single layer of flat cells in contact with the basal lamina (one of
the two layers of the basement membrane) of the epithelium.This type of epithelium is often
permeable and occurs where small molecules pass quickly through membranes via filtration or
diffusion. Simple squamous epithelia are found in capillaries, alveoli, glomeruli, and other
tissues where rapid diffusion is required. It is also called pavement epithelium due to its tile-like
appearance. This epithelium is associated with filtration and diffusion.This tissue is extremely
thin, and forms a delicate lining.

Cells vary in shape & size
Types of Cells:
Based on cellular structure, there are two types of cells:
Prokaryotes - Prokaryotic cells have no nucleus.
Eukaryotes - characterized by a true nucleus.
Structures of cell:
It consist of 3 parts:
Cell membrane outer boundary of cell
Nucleus - control center
Cytoplasm material between cell membrane & nucleus
Cell (plasma) membrane:
Cell structure that regulates passage of materials between cell & its environment; aid in protection & support of cell
Cell wall – cell structure that surrounds cell membrane
2. Nucleus
Nucleus - organelle that controls the cell’s activities & contains DNA
Parts of nucleus:
Nuclear envelope - 2 membranes that surround nucleus of a cell
Nucleolus - cell structure that contains RNA & proteins; where ribosomes are made
Chromosomes - threadlike structure in a cell that contains genetic information that is passed on from one generation of cells to the next
Chromatin – long, tangled strands of DNA
3. Cytoplasm
Cytoplasm – (jelly-like) area between nucleus & cell membrane of a cell
Surrounds organelles
Organelle – tiny cell structure that performs a specialized function within the cell
Cell Organelle and its Functions:
Nucleolus: The nucleolus is the site of ribosome synthesis. Also, it is involved in controlling cellular activities and cellular reproduction
Nuclear membrane: The nuclear membrane protects the nucleus by forming a boundary between the nucleus and other cell organelles.
Endoplasmic reticulum: The endoplasmic reticulum is involved in the transportation of substances throughout the cell. It plays a primary role in the metabolism of carbohydrates, synthesis of lipids, steroids and proteins.
Golgi Bodies: Golgi bodies are called the cell’s post office as it is involved in the transportation of materials within the cell
Ribosome: Ribosomes are the protein synthesizers of the cell
Mitochondria: The mitochondrion is called “the powerhouse of the cell.” It is called so because it produces ATP – the cell’s energy
Lysosomes: Lysosomes protect the cell by engulfing the foreign bodies entering the cell and helps in cell renewal. Therefore, it is known as the cell’s suicide bags
Chloroplast: Chloroplasts are the primary organelles for photosynthesis. It contains the pigment chlorophyll
Vacuoles: Vacuoles stores food, water, and other waste materials in the cell

simple squamous epithelium is a single layer of flat cells in contact with the basal lamina (one of
the two layers of the basement membrane) of the epithelium.This type of epithelium is often
permeable and occurs where small molecules pass quickly through membranes via filtration or
diffusion. Simple squamous epithelia are found in capillaries, alveoli, glomeruli, and other
tissues where rapid diffusion is required. It is also called pavement epithelium due to its tile-like
appearance. This epithelium is associated with filtration and diffusion.This tissue is extremely
thin, and forms a delicate lining.

Tissues including membranes and glands : types, structure and functions
Body cavities and their contents
Cell
Cell is the basic Structural and functional unit
Unicellular Organisms - made up of only one cell
Multicellular Organisms - made up of more than one cell.
Cells vary in shape & size
Types of Cells:
Based on cellular structure, there are two types of cells:
Prokaryotes - Prokaryotic cells have no nucleus.
Eukaryotes - characterized by a true nucleus.
Structures of cell:
It consist of 3 parts:
Cell membrane outer boundary of cell
Nucleus - control center
Cytoplasm material between cell membrane & nucleus
Cell (plasma) membrane:
Cell structure that regulates passage of materials between cell & its environment; aid in protection & support of cell
Cell wall – cell structure that surrounds cell membrane
2. Nucleus
Nucleus - organelle that controls the cell’s activities & contains DNA
Parts of nucleus:
Nuclear envelope - 2 membranes that surround nucleus of a cell
Nucleolus - cell structure that contains RNA & proteins; where ribosomes are made
Chromosomes - threadlike structure in a cell that contains genetic information that is passed on from one generation of cells to the next
Chromatin – long, tangled strands of DNA
3. Cytoplasm
Cytoplasm – (jelly-like) area between nucleus & cell membrane of a cell
Surrounds organelles
Organelle – tiny cell structure that performs a specialized function within the cell
Cell Organelle and its Functions:
Nucleolus: The nucleolus is the site of ribosome synthesis. Also, it is involved in controlling cellular activities and cellular reproduction
Nuclear membrane: The nuclear membrane protects the nucleus by forming a boundary between the nucleus and other cell organelles.
Endoplasmic reticulum: The endoplasmic reticulum is involved in the transportation of substances throughout the cell. It plays a primary role in the metabolism of carbohydrates, synthesis of lipids, steroids and proteins.
Golgi Bodies: Golgi bodies are called the cell’s post office as it is involved in the transportation of materials within the cell
Ribosome: Ribosomes are the protein synthesizers of the cell
Mitochondria: The mitochondrion is called “the powerhouse of the cell.” It is called so because it produces ATP – the cell’s energy
Lysosomes: Lysosomes protect the cell by engulfing the foreign bodies entering the cell and helps in cell renewal. Therefore, it is known as the cell’s suicide bags
Chloroplast: Chloroplasts are the primary organelles for photosynthesis. It contains the pigment chlorophyll
Vacuoles: Vacuoles stores food, water, and other waste materials in the cell
Reproduction
Cell division: Cells need to divide for a number of reasons, including the growth of an organism and to fill gaps left by dead and destroyed cells after an injury, for instance.
There are two types of cell division:
Mitosis
Meiosis

… This short article, Sorting Out SDLC Terminology, attempts to clarify some of the confusion
surrounding SDLC terminology used today in the field of project management. In several
paragraphs, explain (1) what, if anything, the article helped clarify for you; and (2) what you
might like to explore further based on the information provided ...
the article
http://testdog.com/knowhow/Sorting%20Out%20SDLC.html
Acronym for system development life cycle. SDLC is the process of developing information
systems through investigation, analysis, design, implementation and maintenance. SDLC is also
known asinformation systems development or application development. SDLC is a systems
approach to problem solving and is made up of several phases, each comprised of multiple steps:
The software concept - identifies and defines a need for the new system
A requirements analysis - analyzes the information needs of the end users
The architectural design - creates a blueprint for the design with the necessary specifications for
the hardware, software, people and data resources
Coding and debugging - creates and programs the final system
System testing - evaluates the system\'s actual functionality in relation to expected or intended
functionality.
Sorting Out SDLC Terminology
We’ve probably all seen the job postings with a “required skills” line item that reads something
like the following:
Must be expert in a variety of software development methodologies including SDLC, RUP, XP,
PMP, Agile, Waterfall, Spiral, SEI, PMI, CMMI, PIMBOC, and Scrum.
To which, you might reply, “What are they talking about?”
Clearly, there are people in HR and recruiting (and I know some in development) who are
confused about software development methodologies, their names, acronyms, meanings, and
relationships to one another. Let’s try to sort this out a bit.
Untangling the terminology
To begin, many of the terms listed above are not SDLCs. The term SDLC is an acronym that
stands for Software Development Life Cycle (as well as System Design Life Cycle, System
Development Life Cycle and Synchronous Data Link Control). SDLC is used as a generic
umbrella term for any number of software development methodologies.
SDLC by itself is not a methodology. When the term SDLC shows up in a list of methodologies,
it is a clear indicator that the person who wrote this is confused about what it really means.
The internet American Heritage dictionary gives us the following definition for methodology:
-A body of practices, procedures, and rules used by those who work in a discipline or engage in
an inquiry; a set of working methods: the methodology of genetic studies; a poll marred by faulty
methodology.
Some of the SDLCs listed above do not claim to be methodologies. To be more accurate, an
SDLC is anapproach to managing a software deve.

describe how the composition of the population changed Solution.pdf
describe how the composition of the population changed ?
Solution
The major reason for population changes, whether in an individual country or for the whole
world, is the change in birth and death rates. The birth rate is the number of live babies born in a
year for every 1000 people in the total population. Death rates are number of people dying per
1000 people. When birth rates are higher than death rates the population of an area will increase.
migration are the number of people migrate from one country or society to the other. BIRTH
RATE: when babies are born, it results in a population change, The fertility rate in a country
refers simply to the number of children born. This is different from the fecundity rate, which is
the number of children who could be born in a given society. In other words, fecundity is the
biological capacity of humans to produce children.The fecundity rate is greater than the fertility
rate in most cases. Birth rates vary by society for a number of reasons, including personal choice
and social and political factors. Factors such as poverty level, access to contraception, maternal
and infant care, and availability of nutrition all impact the birth rate in a society. DEATH RATE:
As the growth rates increases the death rate also increases. when babies are born, when members
of a society die it changes the population. butthis is refered as the mortality rate, which is simply
the number of deaths that occur in a society. This is usually calculated by looking at the number
of deaths per 1,000 individuals. In the United States, for example, the death rate is 8/1000
people. Just like birth rate, the death rate in a country depends on things such as availability of
quality medical care, disease, war, or famine. MORTALITY: The most important factor that
accounts for a change in population is migration. Generally migration refers to movement; it\'s
the flow or circulation of people in societies. There are two kinds of migration: emigration and
immigration. Emigration means to leave one\'s own country for another. Immigration means to
enter into a country other than one\'s own. Both of these process impact population change. The
composition also depends upon age structure. Age structure varies according to age distribution
of an individual, therefore the population size is expected to double or even triple before
stabilizing for many developing countries with fairly large populations and large numbers of
people under age 15..

*Dewey, The Quest for Certainty, Ch. 1
Veblen, \"Why is Economics Not an Evolutionary Science\"
consisting 500 words, my homework due is today at 10:00 p.m.
Solution
\"Why is Economics Not an Evolutionary Science\" was written in1898. According to veblin the
only rational approach is to assume economies evolve because he argued that we can describe
the economy and have not any effective theory of change and development. Veblen classes the
assumption that that economies ‘normally’ tend towards equilibrium—as no more rational that
the spiritually-based notion that there is a final cause or teleological pull towards some natural
outcome due to natural law; that is, “a preconception regarding the ends to which, in the nature
of things, all things tend (P.392) .Veblen is insistent, however, that we cannot understand
economics without paying attention to human learning.Veblen does not see evolution as
something that happens primarily to individuals but as a collective change to societies, and
collections of institutions.According to him evolution is a dispassionate cumulative
causation..Most of the people including me likes this paper because it reminds us that most of
what we think has been thought before, just not acted upon; because it seems to sow the seeds for
much of what followed in terms of complexity and evolutionary economics.Veblen in his paper
has sheer command of language and he touches on most of the challenges that economist ever
since have raised about.

3 3
Solution
let theta theta = t
from the graph y = f(t) = 3 + 2sin(t)
f(-t) = 3 + 2sin(-t) = 3 - 2sint
therefore f(t) not equal to f(-t)
then f(t) is odd function.
1.S. cerevisiae can switch mating types. Which of the following stat.pdf
1.S. cerevisiae can switch mating types. Which of the following statements correctly summarizes
where the information comes from for it to do this?
Solution
Saccharomyces cerevisiae occurs in two forms, the haploid and diploid. The haploid cells
undergo mitosis, which die under the conditions of higher stress. The preferential form of the
yeast is diploid, which undergoes growth by mitosis.
In cerevisiae, the cells of opposite mating type are present in the same ascus. They are produced
by a single meiosis and mate with each other. Means, the organism can switch mating types. The
mating locus contains two-mating loci in inactive state, which provide the information to replace
the inactive copy at the mating locus with the active copy..
You produce an interference pattern by projecting a blue laser with .pdf
You produce an interference pattern by projecting a blue laser with a wavelength of 405 nm
through the double slits you used in the today’s experiment. The lens is placed 51.2 cm from the
screen. What is the distance between two adjacent bright spots? Show all work.
Solution
Let\'s assume separation between the slits is, d = 0.10mm = 10-4 m
Wavelength of light, Lembda = 405 x 10-9 m
Distance of screen, D = 51.2 x 10-2 m
Distance between two adjacent bright spots = D x Lemda / d
= [51.2 x 10-2 x 405 x 10-9 ] / 10-4 = 2.07 mm.

You deposit $1,000 in a fund earning 5.75%. How long will it take to double your money?
Solution
Let us suppose that it will take n years to get double. Hence,
1000(1+0.0575)^n=2000
or,log1000+nlog(1.0575)=log2000
or, 3+0.024280n=3.30102
or, n=0.301029/0.024280=12.3
Hence it will take almost 12.3years to get double.

Which of the following statements is true about the interaction of e.pdf
Which of the following statements is true about the interaction of electromagnetic radiation with
matter?
1) Photoelectric absorption involves the interaction of a photon with the nucleus of an atom.
2) Rayleigh scattering involves an inelastic collision of a photon with an outer-shell electron with
negligible binding energy, after which that electron is ejected from the atom.
3) The main phenomena associated with X-ray imaging are Rayleigh scattering at low photon
energies and pair production at high photon energies.
4) The main phenomena associated with X-ray imaging are photoelectric absorption at low
photon energies and Compton scattering at high photon energies.
5)None of these statements are true.
Please explain why.
Solution
1) The statement is true.
The photons with atom particles are by chance, a given photon has a finite probability of passing
completely through the medium it is traversing. The probability that a photon will pass
completely through a medium depends on numerous factors including the photon’s energy and
the medium’s composition and thickness. The more densely packed a medium’s atoms, the more
likely the photon will encounter an atomic particle.
2)False
The photons doest not excite the atom when it interacts with the one or more bounded electrons.
The energy is same at the end of the process, that is energy of photon is equal to the interacting
atom. Therefore, it is elastic scattering.
3)
This statement is true.
Rayliegh scattering involves in deflection of the incoming particle, but not absorption.hence it
occurs for low photon energies. Whereas the pair productionrequires very high energy as the
photon interacts with the electron or nucleaus and forms postiron electron pairs. The photon must
have atleast 1.022 MeV energy to interact.
4)
The statement is false.
As the photoelectric absorption involves in absorption of photons by atoms which have
considerably high energy as discussed in first point.
So statements 1 and 3 are true..
Which of the following identifies an underlying principle of the com.pdf
Which of the following identifies an underlying principle of the communicative or “Acquisition
vs. Learning” approaches to the instruction of English Language Learners?
Select one:
a. Students should follow a step-by-step progression on English instruction from simpler to
more difficult tasks.
b. Students develop skills in English by mastering the written grammar of the language
c. Students should have repeated exposure to accurate models of oral English in the formal
register
d. Students develop English language skills by figuring out the meaning of English words in
interactions with other people
Solution
d. Students develop English language skills by figuring out the meaning of English words in
interactions with other people
because communication principle involves classroom interaction and aqusition vs learning means
to learn the few words and acquire them one by one by knowing their meanings and gradually
forming the sentences as a whole with these words..

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
