There are three main types of insects larvae
1. oligopod: Scarabeiform, Campodeiform
2. polypod: Hairy caterpillar, Slug caterpillar, Looper, Semilooper
3. apodous: Euciphalous, Hemicephalous, acephalous
1) OLIGOPOD: a) Campodeiform:
• Have resemblance to the dipluran genus campodea.
• Body is elongate, depressed dorso ventrally and well
sclerotised.
• Head is prognathous.
• Thoracic legs are long.
• A pair of abdominal cerci
is usually present.
• Larvae are generally predators
and are very active.
• Eg: grub of ant lion, grub of lady bird beetle
b) Scarabaeiform:
• Body is ‘C’ shaped, stout and subcylindrical.
• Head is well developed.
• Thoracic legs are short.
• Caudal processes are absent.
• Larva is sluggish, burrowing into wood or
soil.
• Eg: grub of rhinocerous beetle.

All animals have external structures, or bodily organs on the outside. The majority of animals have a head, a body covering, limbs, and a tail of some kind. These body parts are all essential to an animal's ability to live and reproduce, despite the fact that they may appear differently on different animals.
The limbs of mammals may be modified for a particular movement. They could be taught how to swim, fly, climb, and run. More commonly known as "ricochetal locomotion," saltatory (leaping) movement has been observed in a variety of unrelated species (some marsupials, lagomorphs, and several independent lineages of rodents).
The skin of mammals, like that of other vertebrates, consists of epidermal and dermal layers. It protects against actual injury, microbiological invasion, and UV rays from the sun. skin is also important for temperature regulation, sensory perception excretion, and water regulation.
Hairs are a keratinized derivative of the epidermis of the skin and are uniquely mammalian. It is seated in an invagination of the epidermis called a hair follicle. Two distinct kinds of hair typically compose a pelage, a coat of hair. Long guard hairs protect a dense coat of shorter, insulating under hairs.
Hair must periodically molt because it is made mainly of dead cells. In some mammals (e.g., humans), molting occurs gradually and may not be noticed. Others have rapid hair loss, which could alter the characteristics of their pelage. In the fall, many mammals acquire a thick coat of insulting under hair, and the pelage color may change.
For example, the Arctic fox takes on a white or cream color with its autumn molt, which helps conceal the fox in a snowy environment. with its spring molt, the Arctic fox acquires a gray and yellow pelage
Hairs are also important for the sense of touch. The mechanical displacement of hair stimulates nerve cells associated with the hair root. Guard hairs may sometimes be modified into thick-shifted hairs called vibrissae. Vibrissae occur around the legs, nose, mouth, and eyes of very sensitive to displacement.
Air space in the hair shaft and hair trapped between hairs and the skin provides an effective insulating layer. A band of smooth muscle, called the arrector pili muscle, runs between the hair follicle and lower epidermis. when the muscle contract, the hair stands upright, increasing the amount of air trapped the in the pelage and improving its insulating properties.
Arrector pili muscles are under the control of the autonomic nervous system, which also controls a mammal's "fight-or-flight" response. In threatening situations, the hair stands on end and may give the perception of increased size and strength.
Hair color depend on the number of pigments (melanin) deposited in it and the quantity of air in the hair shaft. The pelage of most mammals is dark above and lighter underneath. This pattern them less conspicuous under most conditions. Some mammals advertised their defenses using aposematic (warning

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

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.

Comparative anatomy
1. Comparative Anatomy Lab
Lab 10: Cat Dissection Week 1
Bio-220L-W02
Aim: To dissect and examine the internal anatomy of the cat.
Introduction:
2. This week, we will dissect a cat in order to understand anatomy better. Interesting creatures
that they are, cats have many unique characteristics. Their eyes and ears aid them with every
move while their coat functions as a blanket in winter and their tongue acts as a comb as well
as a warming and cooling device. Cat anatomy is the simple anatomy or consideration of the
structure of the internal body parts of a cat. Concisely, as a cat is a carnivore since long
times, it has its mouth and claws specially adapted for victimizing the prey. It has the
sharpest sense organs for early caution and various other specialties. Cats have highly
specialized teeth for the killing of prey and the tearing of meat. The premolar and first
molar together compose the carnassial pair on each side of the mouth, which efficiently
functions to shear meat like a pair of scissors. While this is present in canids, it is highly
developed in felines. The cat's tongue has sharp spines, or papillae, useful for retaining and
ripping flesh from a carcass. These papillae are small backward-facing hooks that
contain keratin which also assist in their grooming. Like nearly all members of the
family Felidae, cats have retractable claws. In their normal, relaxed position, the claws are
sheathed with the skin and fur around the toe pads. This keeps the claws sharp by preventing
wear from contact with the ground and allows the silent stalking of prey. ats possess rather
loose skin; this allows them to turn and confront a predator or another cat in a fight, even
when it has a grip on them. This is also an advantage for veterinary purposes, as it simplifies
injections. In fact, the lives of cats with kidney failure can sometimes be extended for years
by the regular injection of large volumes of fluid subcutaneously, which serves as an
alternative to dialysis. Cats possess rather loose skin; this allows them to turn and confront a
predator or another cat in a fight, even when it has a grip on them.

3. Place specimen on the tray dorsally.
4. Take scalpel and cut the specimen starting from the anterior mid-sagittal plane.
5. Identify the structures accordingly.
6. Draw all the models as displayed once the dissection is complete
Results/Diagrams:
4. - The drawings of all the skeletons and dissections are attached and labeled accordingly.
Discussion:
Although we did not dissect the cat today, we did examine the external physical features of
the cat through the bag that it was enclosed in. In addition, we sketched more models of cats,
birds, and reptiles. This provided us with a better understanding of the skeletal anatomy of all
of these creatures. The cat is a very complex mammal that shares many characteristics
similar to humans. By understanding the cat better, we can better understand humans.
Conclusion:
Cats are mammals classified as Felis catus under the current scientific classification system.
Domestic cats are characterized by a number of well-known physical characteristics. These
include a flexible and compact body, keen eyesight and adaptations for visual acuity at night,
retractable claws, sharp teeth and a reduction in numbers of teeth reflecting adaptation as a
carnivore, long vibrissae, and a long and flexible tail important as an aid to balance. The
domestic cat was first classified as Felis catus by Carolus Linnaeus in the tenth edition of
his Systema Naturae of 1758. However, because of modernphylogenetics, domestic cats are
now usually regarded as another subspecies of the Wildcat Felis silvestris. This has resulted
in mixed usage of the terms, as the domestic cat can be called by its subspecies name, Felis
silvestris catus. Wildcats have also been referred to as various subspecies of F. catus, but in
2003 the International Commission on Zoological Nomenclature fixed the name for wildcats
5. as F. silvestris. The most common name in use for the domestic cat remains F. catus,
following a convention for domesticated animals of using the earliest (the
senior) synonym proposed. Sometimes the domestic cat is called Felis domesticus or Felis
domestica, the term coined by German naturalist Johann Christian Polycarp Erxleben in
1777. These are not valid taxonomic names, and Linnaeus's binomial takes precedence. Cats
have 7 cervical vertebrae like almost all mammals, 13 thoracic vertebrae (humans have 12),
7 lumbar vertebrae (humans have 5), 3 sacral vertebrae like most mammals (humans have 5
because of their bipedal posture), and a variable number of caudal vertebrae in the tail
(humans retain 3 to 5 caudal vertebrae, fused into an internal coccyx). The extra lumbar and
thoracic vertebrae account for the cat's spinal mobility and flexibility. Attached to the spine
are 13 ribs, the shoulder, and the pelvis. Unlike human arms, cat forelimbs are attached to the
shoulder by free-floating clavicle bones, which allow them to pass their body through any
space into which they can fit their heads.
