The document discusses cell and tissue types in the human body. It begins by outlining the hierarchical organization of biological structures from atoms to the biosphere. It then discusses how cellular differentiation through mitosis allows for the formation of complex multicellular organisms. The main animal tissue types are identified as epithelial, nervous, muscle, and connective tissues. Each tissue type is described in terms of its characteristic cell types and functions. Connective tissue is discussed in further detail regarding its main cell types, extracellular matrix components like collagen and elastic fibers, and examples of connective tissue diseases.
detail notes on connective tissue..
Connective tissue (CT) is one of the four basic types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue. It develops from the mesoderm. Connective tissue is found in between other tissues everywhere in the body, including the nervous system. In the central nervous system, the three outer membranes (the meninges) that envelop the brain and spinal cord are composed of connective tissue.
All connective tissue consists of three main components: fibers (elastic and collagenous fibers), ground substance and cells. Not all authorities include blood or lymph as connective tissue because they lack the fiber component. All are immersed in the body water.

Skeletal System, Muscular System, and Biological Organization PowerPoint Reve...www.sciencepowerpoint.com
This PowerPoint Review Game is one very small part of a larger science unit from www.sciencepowerpoint.com. This unit comes with a bundled homework package, detailed lesson notes, worksheets, review games, and much more. The Human Body Systems and Health Topics Unit uses a 13 Part 8,500 slide interactive PowerPoint full of critical class notes, review opportunities, video and academic links, and much more to deliver an entire unit of study. Learn more at www.sciencepowerpoint.com.
I don't play this game like Jeop_ _ dy, instead, students record the answers 1-25 as they work in small table groups. Each question 1-20 is worth 5 pts while 20-25 are all bonus questions worth 1 pt each. The bonus round for this game has to do with superheroes with "atomic-like power" The final question is a 5 point wager question. The answers are provided after the review in PowerPoint form so the students can self assess. The questions are previewed one last time before the answers are revealed so the teacher can call upon table groups or individual students for the answer. This is just one of the review games provided in the unit described above.
Thank you for your time
What structural characteristics did you observe for each type of tis.pdfnaveenkumar29100
What is the probability of having a boy, then a girl, then a boy, and then two girls in that birth
order?
Solution
Probability of boy P(b) = 1/2
and probability of girl is also P(g) = 1/2
as they are the only 2 outcome possible and are equally likely
So probability of having a boy, then a girl, then a boy, and then two girls =
P(b)*P(g)*P(b)*P(g)*P(g)
= 1/2 * 1/2 * 1/2 * 1/2 *1/2 = 1/32 =0.03125.
Every organism is composed of several different types of human body tissue. The human body tissue is another way of describing how our cells are grouped together in a highly organized manner according to specific structure and function. These groupings of cells form tissues, which then make up organs and various parts of the body.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

1. Cell Tissue - Questions and Answers
1. What is the logical order in which the concepts of atoms, molecules, cells...
up to biosphere are associated?
Atoms form molecules that form cells that form tissues that form organs that form
systems. Systems, in their turn, constitute individuals that form populations that
compound (biological) communities that form the biotic components of ecosystems. All
ecosystems of earth form the biosphere.
2. From the zygote, pluricellular organisms are formed by serial mitosis. Would
this formation be possible if each cell made by mitosis had an identical life in
relation to its antecedent cells? How did evolution solve that problem?
The formation of complex and distinct pluricellular organisms would not be possible if
mitosis in embryos produced only daughter cells with an identical life history as the
mother cell, since there would not be differentiation and structural or functional
specialization among cells.
Evolution solved the problem creating the cellular differentiation process by which,
motivated by stimulus not yet well-known by science, different and specialized cell
lineages gave birth to different tissues, organs and systems that, as a whole, form the
pluricellular organisms.
Cellular differentiation probably is a very intricate process that activates and inactivates
some genes within the cell in response to some stimulus.
3. What are the main types of animal tissue?
The main animal cell tissues are the epithelial tissue, the nervous tissue, the muscle
tissue and the connective tissue.
Image Diversity: epithelial tissue nervous tissue muscle tissue connective tissue
4. What are epithelial tissues? What are their general function and how is that
function associated to the features of the tissue?
Epithelial tissues, also called epithelia, are tissues specialized in the covering of external
and internal surfaces of the body.
The general function of the epithelium is to provide protection and impermeability (or
selective permeability) to the covered structure. This justifies the epithelium's typical
features: the cellular juxtaposition forming layers of very proximate cells with diminished
or none intercellular space between each two neighbor cells.
Image Diversity: epithelial cell
5. Of which cells is the nervous tissue constituted? How is the generic function
of this tissue related to the characteristics of the main cell type that forms it?
The nervous tissue is formed of neurons and glial cells.
The function of the nervous tissue is to receive and to transmit neural impulses
(reception and transmission of information). This function justifies the characteristic
2. morphology of neurons, with membrane projections (dendrites) to get information and
an elongated membrane projection (axon, or nerve fiber) to transmit information at
distance. In their turn, the glial cells support the neurons and facilitate their work
(sometimes acting as insulators).
Image Diversity: neuron glial cell
6. What are muscle tissues? How is the function of this tissue related to the
typical characteristics of its cells?
Muscle tissues are tissues made of cells able to perform contractions and thus to
generate movement.
The function of the muscle tissue is to pull bones (skeletal striated muscle), to contract
and move viscera and vessels (smooth muscle) and to make the heart to beat (cardiac
striated muscle). The muscle cells have internal structures called sarcomeres where
there are myosin and actin molecules disposed to create contraction and distension
(movement).
Image Diversity: muscle cell
7. What is the typical biological function of the connective tissues? How is this
function associated to the main features of its cells?
The typical function of the connective tissues is to fill empty spaces among other body
tissues.
This function is related to the great capability of the cells of the connective tissue to
secrete substances that constitute extracellular material, like collagen and elastic fibers,
creating a significant spacing between these cells.
(There are other important biological features of the connective tissues, such as
substance transportation, defense of the organism, etc.)
8. Of which type of tissue are cartilages and bones made?
Bones and cartilages, tissues with great amount of intercellular material, are formed of
connective tissue.
9. Are the cells of the connective tissue far or near to the others?
The relative great spacing between cells is a typical feature of the connective tissue.
There are much intercellular material generally secreted by the tissue cells.
10. What are the general functions of the connective tissues?
The main functions of the connective tissues are: supporting and filling of spaces;
cellular nutrition; energetic storage (fats); hematopoiesis (formation of blood, blood cells
and blood components); immune defense (specialized cells).
11. What is connective tissue proper?
The name connective tissue proper is used to designate the connective tissue that fills
interstitial spaces as opposed to the specialized connective tissues (blood, bones,
cartilage, adipose tissue, etc.). The connective tissue proper secretes collagen, elastin
and reticular fibers.
3. 12. What are the main cells of the connective tissue proper? What is the name
given to the intercellular material that surround these cells?
The main cells of the connective tissue proper are the fibroblasts, cells that secrete the
intercellular material. These cells are the majority of cells of the tissue. Fibroblasts later
are transformed into fibrocytes, mature cells with restricted secretory role.
The intercellular substance that fills the interstice is called interstitial matrix, or just
matrix.
Image Diversity: fibroblast fibrocyte interstitial matrix
13. What are the three types of protein fibers of the connective tissue proper?
The matrix of the connective tissue proper is made of collagen fibers, elastic fibers and
reticular fibers.
Image Diversity: collagen fibers elastic fibers reticular fibers
14. What is the function of the collagen fibers of the connective tissue?
There are different collagen types. The main function of these proteins is to keep the
shape and the structural rigidity of the tissue. (Collagen is the most abundant protein of
the human body.)
15. Of which substance do elastic fibers of the connective tissue are made?
What are some functions of these fibers?
The elastic fibers are made of a protein called elastin.
Elastic fibers abound in artery walls, helping the maintenance of the arterial blood
pressure in these vessels. They are also present in the lungs, providing them with
elasticity (some respiratory diseases are caused by destruction of these fibers). In many
other organs and tissues the elastic fibers are found in the interstitial matrix.
16. What are the reticular fibers of the connective tissue and where can they be
found?
The reticular fibers are very delicate interstitial fibers made of a special type of collagen
known as collagen type III. They can be found in many organs and tissues such as in
lymphnodes, in the spleen, in the liver, in blood vessels and also covering muscle fibers.
17. What are diseases of the connective tissue? What are some of them?
Diseases of the connective tissue are hereditary or acquired diseases(many of
autoimmune cause) characterized by deficiency in structure or function of components of
the connective tissue, for example, deficiencies of collagen, elastin, etc. Some of such
diseases are lupus, dermatomyositis, cheloid, scleroderma, mixed connective tissue
disease, mucinosis and Marfan's syndrome.
