Structure of integument its function, moulting.pptxvineetha43
Slide 1
Insect body wall is called as Integument or Exoskeleton.
It is the external covering of the body which is ectodermal in origin
It is rigid, flexible, lighter and stronger
Slide 2
Structure of body wall consists of an outer non cellular part (cuticle), an inner cellular layer (epidermis), basement membrane
Epidermis - It is an inner unicellular layer resting on basement membrane
It’s functions:
i. Cuticle secretion &
Secretion of moulting fluids
ii. Digestion and absorption of old cuticle
iii. Wound repairing
iv. Gives surface look, protection, muscle attachment
v. Water-tight barrier against desiccation, and a sensory interface with environment.
Slide 3
Cuticle - It is an outer non cellular layer comprising three sub layersSub layers of cuticle
i. Endocuticle
Innermost and thickest layer made up of chitin and arthropodin. This layer is colourless, soft and flexible
ii. Exocuticle
Outer layer, much thicker & harden with composition of chitin and sclerotin. This layer is dark in colour and rigid

• Bioremediation – process of cleaning up environmental sites contaminated with chemical pollutants by using living organisms to degrade hazardous materials into less toxic substances
• Nutrient cycles referred to as biogeochemical cycles
• Gaseous forms of carbon, oxygen, and nitrogen occur in the atmosphere and cycle globally
• Less mobile elements, including phosphorous, cycle on a more local level
• Still, gains and losses from outside of the ecosystem are generally small when compared to the rate at which nutrients are cycled within the system.
ART refers to methods used to achieve pregnancy by artificial or partially artificial means.
• INCLUDES- artificial insemination, In vitro fertilization (IVF) , Zygote intrafallopian transfer (ZIFT) or Tubal Embryo Transfer, Gamete intrafallopian transfer (GIFT) , Intracytoplasmic sperm injection (ICSI)
There needs to be a balance between water ingested and water eliminated.
In order to maintain homeostatic levels of water, the body must undergo osmoregulation.
A number of morphologically and functionally diverse organs and tissue organs and tissue contribute to the development of immune responses .
These organs can be distinguished by function as the primary and secondary lymphoid organs .
In five kingdom classification(scheme proposed by R. Whittaker in 1969), Protists make up a kingdom called “Protista”, composed of “Organisms which are unicellular or unicellular-colonial and which form no tissue.
Protists are the eukaryotes that are not members of the kingdom Plantae, Animalia or Fungi. Most Protists are unicellular, but few have hundreds or even thousands of cells.
Protists can be autotrophic or heterotrophic.
They move by cilia, flagella or pseudopodia.
Microbial cultures are foundational and basic diagnostic methods used extensively as a research tool in molecular biology.
Microbial cultures are used to determine the type of organism, its abundance in the sample being tested, or both.
It is one of the primary diagnostic methods of microbiology and used as a tool to determine the cause of infectious disease by letting the agent multiply in a predetermined medium.
It is often essential to isolate a pure culture of microorganisms

o Snow leopard known throughtout the world for its beautiful fur and elusive behavior, the endangered snow leopard () is found in the rugged mountains of central asia.
o They are perfectly adapted to the cold, bareen landscape of their high altitude home, but human threats have created an uncertain future for the cats.
o Scientist estimate that there may only be between 3920-6390 snow leopard left in the wild.
Honey bees are social insects, which means that they live together in large, well-organized family group.
Communication, complex net construction, environmental control, defense and divison of the labor are just some of the behaviour that honey bees have developed to exist successfully in social colonies.
A honey bees colony typically consists of three kinds of the bees 1) Queen. 2) Workers. 3) Drones.
In addition to thousands of workers adults, a colony normally has a single queen & several hundred drones.
Honey bees live in comb or nest.
Mutual cooperation exist.
Developed communication Dance.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
3. • Insect are member of one of the biggest classes and phylum
arthopoda ( non chordates) with jointed legs.
• Body divided into head, thorax and abdomen.
Insect :-
4. General characters:-
• Triploblastic coelomate with bilateral symmetry.
• Segmented body aned jointed appendag.
• Exoskeleton.
• Lomotary system with skeleton muscles.
• 3 pair of peristomal appendages.
• Sense organ,antennae and coumpound eyes.
6. Abdomen :-
• An insect’s abdomen is third function region(tagma) of it’s
body .
• The abdomen is located is just behind the thorax.
• It consist of sclerotized, tergum and sternum.
• They jointed by membranous pleural region which are
commonly hidden beneath the sides of the tergum
7. • There is no sclerotization and the abdomen consist of serious
of membranous segments. This is true in many diptera,
coleoptera and hymenoptera
• The tergum sternum and pleural element sometimes fuse to
form a complete sclerotized ring this is in ephemeroptera and
dermaptera.
• In acrididae terga of segments 9 and 10 fuse together
• In some coleoptera the second sternum fuse with the next two
and the sutures between them are largely obliterated.
8. • The reproductive opening of male insect is usually on segment 9 .
• In females insect the opening of oviduct is on or behind segment 8
and 9.
•
9. Abdominal structure:-
• Spiracle :- opening of the respiratory system near the pleural
membrane on each side of the first eight abdomen.
• Anus :- rear opening to the respiratory system is present between
three protective sclerites.
• Cerci :- the pair of sensory organ located near the anterior margin
of paratop.
• Clasper :- the external genitalia may also include other sclerites.
10. Other abdominal structure
• Pincers :- the cerci are heavily sclerotized and foreceps. They are
used mostly for defense and sometimes to help in folding the
wing. ex- dermaptera.
• Median caudal filament :- a thread like projection arising
between the cerci. Ex- diplura, thysanura.
• Cornicles :- paired secretory structure located dorsally on the
abdomen of aphids. They produces substance that repel
predators or care-giving behavior by symbiotics ants.
11. • Abdomen proleg :- flesy locomotary appendages found only in
the larvae of certain order.
• Sting :- a modified ovipositor, found only in females of aculeate
hymenoptera.
• Abdominal gills :- respiratory organ found in the
nymphs(naiads) of certain aquatic insect.
12. • Furcula :- jumping organ. In springtail found in collembolan
on the ventral side of the fifth abdominal segment.
• Collophore :- a flesy peg like str. Found in collembola on the
ventral side of first abdominal segment. It appears to maintain
homeostasis by regulation of water from the environment.
