Group C is presenting on the phyla Arthropoda and Annelida. Their presentation includes definitions and characteristics of arthropods such as their exoskeleton, jointed legs, and segmented bodies. The major classes of arthropods are discussed including insects, crustaceans, arachnids, centipedes, and millipedes. The anatomy and life cycle of cockroaches is explained in detail. Amazing facts about cockroaches are provided such as their ability to live for over a week without a head and hold their breath for 40 minutes.
Insects, spiders, crabs, shrimp, millipedes, and centipedes are all arthropods. Arthropods have jointed feet, a segmented body, and an exoskeleton, a cuticle on the outside of their body. Arthropods have by far the greatest number of species of any animal group, at around 900,000 species
Pentaceros is an echinoderm, ie spiny skin organism, It is remarkably known for its five arms and regenerative capabilities, the presentation discusses various aspects of its nomenclature, taxonomy, biology including feeding, reproduction, development, ecological significance. It has direct similarities to the most primitive chordates the hemichordates during their development hence play an integral role in the evolution story as a connecting link.
the presentation will help you learn more about how the insect eyes really work in field conditions and more over for the better understanding you can take help from from book: THE INSECTS:STRUCTURE AND FUNCTION byR.F.CHAPMAN.....as the contents of my presentation are from that book only.....
The ppt covers Introduction
Feeding habits in –, Phytophagous insects, Mycetophagous insects, Predaceous insects, Parasitic mode of nutrition ,Sensory organs associated with feeding, Sensilla on the mouthparts, Food selection by phytophagous insects, Prey specificity and selection by predators
Host- finding by blood- sucking and parasitic insects
Significance of food preferences

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.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
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

Honest Reviews of Tim Han LMA Course Program.pptxtimhan337
Personal development courses are widely available today, with each one promising life-changing outcomes. Tim Han’s Life Mastery Achievers (LMA) Course has drawn a lot of interest. In addition to offering my frank assessment of Success Insider’s LMA Course, this piece examines the course’s effects via a variety of Tim Han LMA course reviews and Success Insider comments.
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.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Protection
Arthropods are protected by fast movement, an exoskeleton,
pinchers, camouflage, and poison glands.
Movement
The fast movements of arthropods are the combined result of
jointed appendages, a hard skeleton, and fast acting striated
muscle.
o Digestion
Digestion is extracellular in the gut
14. Phylum Arthropoda
Circulation
Arthropods have an open circulatory
system. They have a dorsal heart
Excretion
Crustaceans excrete through nephridia or green
glands. Others use a network of Malpigian tubes
which collects liquid wastes in the gut.
15. Phylum Arthropoda
Respiration
Crustaceans use gills. Insecta, chilopoda, and
diplopoda use trachea and spiricles. Arachnids
use book lungs.
Nervous System
Arthropods have a highly complex nervous system
with a brain and a ventral nerve cord. They also
have compound eyes,touch receptors,
chemoreceptors, and auditory receptors.
16. Phylum arthropoda
Reproduction
Most have separate sexes and
internal fertilization. Most undergo
some form of metamorphosis.

head,ii) the thorax and iii) the abdomen.
three pairs of jointed legs,(18 knees)
one pair of antennae (sensory organs)and
a rigid exoskeleton
HEAD
Head have eyes,antennae
brain,
22. Head
much of their nervous system activity
takes place in nerve ganglia located
throughout their bodies. This is one of the
reasons why a headless roach can live for
more than a week. The other is that
roaches don't breathe through a nose or
mouth. Instead, they draw air through
spiracles, or holes in their sides. Tubes
called tracheae deliver oxygen from the
spiracles to organs and tissues. When a
headless roach finally dies, it dies of thirst.
24. Cockroach
The Thorax
attachments for three pairs of legs
two pairs of wings
prothoracic legs are closest to the head.
The middle legs are the mesothoracic
legs.
The very long metathoracic legs are the
roach's back legs,
25. Cockroach
The Abdomen
contains most of their internal organs,
tube-like heart moves blood to organs and
tissues.
much of the blood travels through a
network of spaces called a hemocoel.
26. cockroach
Biology
An adult female cockroach produces an egg
capsule
A cockroach has three stages during its life
cycle: egg, nymph, and adult. Adults lay eggs
contained within egg cases that are dark-colored
and roughly the same size and shape
as a dry kidney bean. Depending on the
species, an egg case contains between 16 -
50 eggs. Eggs hatch into young cockroaches
called nymphs. In a normal cockroach
population, nymphs are more numerous than
adults.
27. Amazing Cockroach facts
1. Cockroach can live up to nine
days without its head
2. If a cockroach breaks a leg it can
grow a new one
3. A cockroach can change
directions up to 25 times in a
second
4. Cockroaches can run up to
3km/hr (0.8 m/s)
28. cockroach
5. A cockroach can hold its breath
for up to 40 minutes if necessary
6. Cockroaches can survive without
food for a month and a week
without water
7. Coakroaches spend at least 75%
of their time in resting
29. cockroch
8. Some of the female cockroaches can mate
once and remain pregnant for the rest of lives
9. Young cockroaches only need a crack ~
0.5mm wide to crawl into the house. Adult can
squeeze into a space of 1.6mm while pregnant
