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.

2. 1) Tissues
Tissue is a group of cells having similar structure and function.
In plants and animals groups of cells called tissues carry out
specific functions.
Example :- In human beings the cells of the muscular tissue contract and relax
and help in movement. In plants the cells of the vascular tissue conduct water and
food from one part of the plant to the other.
Animal Tissue Plant Tissue
3. 2) Differences between plant and animal tissues
a) Plant tissues :-
i) Plants do not move from place to place. Most of the cells and
tissues in plants provide mechanical support and strength. So most
of the tissues consists of dead cells because they provide
mechanical support and strength to the plant.
ii) The growth of plants takes place only in some regions. So plants
have tissues called meristematic tissues which divide and help in
growth and permanent tissues which do not divide.
b) Animal tissues :-
i) Animals move from place to place and need more energy than
plants. So most cells and tissues in animals are living cells.
ii) The growth of animals is more uniform so animals do not have
separate dividing and non dividing cells. Animals have organs
having specialized functions. So the organs have specialized
tissues.
4. 3) Plant tissues
Plant tissues are of two main types. They are Meristematic tissues and
Permanent tissues.
i) Meristematic tissues : are of three types. They are Apical meristematic
tissues, Intercalary meristematic tissues and Lateral meristematic tissues.
ii) Permanent tissues : are of two types . They are Simple permanent tissues
and Complex permanent tissues. Simple permanent tissues are of three
types. They are Parenchyma, Collenchyma and Sclerenchyma. Complex
permanent tissues are of two types. They are Xylem and phloem.

5. A. Meristematic tissue
A.1 Apical meristematic tissues : are present in the tips of stems and
roots. They help in the growth of stems and roots.
A.2 Lateral meristematic tissues :- are present in in the sides of stems
and roots. They help to increase the girth of the stems and roots.
A.3 Intercalary meristematic tissues :- are present at the base of
leaves and internodes and help in the growth of those parts.
Meristematic tissues are found in the growing regions of the plant like the tips of root,
stem and branches. They divide continuously and help in the growth of the plant. They
are of three types :

10. B. Permanent tissue
Permanent tissues are formed from meristematic tissues. They do not divide
and have permanent shape and size. They differentiate into different types of
permanent tissues. Permanent tissues are of two main types.
They are Simple permanent tissues and Complex permanent tissues.
B.1. Simple permanent tissues :
Simple permanent tissues are made up of one type of cells. They are of three types
called Parenchyma, Collenchyma and Sclerenchyma ~
B.1.1 Parenchyma
Parenchyma consists of loosely packed thin walled cells having more intercellular
spaces. They are the basic packing tissues of plants.
Some parenchyma cells in leaves contain chloroplast and prepares food by
photosynthesis. They are called Chlorenchyma .
Some parenchyma cells have large air cavities which help the plant to float on
water. They are called Aerenchyma.
Some parenchyma cells of roots and stem store water and minerals.
11. B.1.2 Collenchyma
Collenchyma consists of elongated cells having less intercellular
spaces and thicker at the corners.
They give flexibility and allows easy bending of different parts like
stem, leaf etc.
They also give mechanical support to the plant.
B.1.3 Sclerenchyma
Sclerenchyma consists of long, narrow, dead thick walled cells.
The cell walls contain lignin a chemical substance which act like
cement and hardens them.
It gives strength, stiffness and hardness to the plant parts.
15. B.2 Complex permanent tissues
These are made up of more than one type of cells. There are two types of complex
tissues. They are Xylem and Phloem. They are called vascular or conducting tissues.
B.2.1 Xylem : consists of tracheids, vessels, xylem parenchyma and
xylem fibres. The tracheids and vessels help to transport water and minerals from
roots to all part of the plant. Xylem parenchyma stores food and fibres help in
support.
B.2.2 Phloem : consists of sieve tubes, companion cells, phloem parenchyma and
phloem fibres. The sieve tubes and
companion cells transports food
from leaves to all parts of the plant.
Phloem parenchyma stores food
and fibres help in support.
17. 4) Animal tissues
Animal tissues are of four main types . They are :- Epithelial tissue, Muscular tissue,
Connective tissue and Nervous tissue.
i) Epithelial tissues are of different types. They are :- Squamous, Columnar,
Cuboidal, Glandular etc.
ii) Muscular tissues are of three types. They are :- Striated, Unstriated and
Cardiac.
iii) Connective tissues are of different types. They are :- Blood, Bone,
Ligaments, Tendons, Cartilage, Areolar, Adipose etc.
iv) Nervous tissue consists of nerve cells called neurons.

Cartilage
Areolar
Adipose
18. A. Epithelial tissue
Epithelial tissue is the covering or protective tissue in animals. It forms the outer covering
like skin, outer covering of organs, inner lining of blood vessels, lungs, oesophagus, etc. It
protects the body and controls the movement of materials between the body and the
surroundings and between the parts of the body. The cells are closely arranged and have a
fibrous basement membrane.
A.1 Squamous epithelial tissue : consists of a layer of thin flat cells. It is
present in the linings of blood vessels, lungs, mouth, oesophagus etc. The
skin has several layers of epithelial cells. This tissue is called Stratified
squamous tissue.
A.2 Columnar epithelial tissue : consists of tall pillar like cells. It is present in
the walls of the intestine. The columnar epithelial tissue in the respiratory
tract has hair like projections called cilia. This tissue is called Ciliated
columnar epithelial tissue.
A.3 Cuboidal epithelial tissue : Consists of cone shape cells having a basement
membrane. It forms the lining of kidney, tubules and ducts of salivary glands
and provide mechanical support.
A.4 Glandular epithelial tissue : Sometimes epithelial tissue folds inwards and
forms a multicellular gland which secretes substances. This tissue is called
Glandular epithelial tissue.
21. B. Muscular tissue :-
Connective tissue helps in the movements of the body. It consists of
elongated cells called muscle fibres. It contains a protein called contractile
protein which contracts and relaxes and helps in
movements. Muscles which can move under our will are called voluntary
muscles.
Muscles which do not move under our will are called involuntary muscles.
B.1 Striated muscles : are voluntary muscles having light and dark
striations. The cells are long, cylindrical and are multinucleated.
They are also called skeletal muscles because they are attached to
bones. They help in voluntary movements of the body.
B.2 Unstriated muscles (Smooth muscles) : are involuntary muscles
having no striations. The cells are long and spindle shaped and are
uninucleated. They are present in alimentary canal, blood vessels,
bronchi of lungs, iris of eye etc. They help in involuntary
movements.
B.3 Cardiac muscles : are involuntary muscles having faint striations.
The cells are long, cylindrical, branched and multinucleated. They
are present in the heart and helps in the contraction and relaxation
of the heart.
23. C. Connective tissue
Connective tissue connects and joins the different parts of the body
together. The cells of the connective tissue are loosely packed and the space
between the cells are filled with a jelly like matrix.
C.1 Blood : Blood contains a fluid matrix called plasma which contains red
blood cells (RBC), white blood cells (WBC) and platelets. The blood transports
gases, digested food, hormones, waste materials etc.
C.2 Bone : is a hard and strong tissue. It consists of cells which are embedded in
a hard matrix containing calcium and phosphorus compounds. Bone forms the
framework of the body and supports the body and the main organs.
C.3 Ligaments : are flexible tissues which joins bones together and helps in
movements.
C.4 Tendons :- are fibrous tissues which joins muscles to bones and helps in
movements.
C.5 Areolar tissues : fills the space between skin and muscles, inside the
organs, around blood vessels etc. It helps to repair the tissues.
C.6 Adipose tissue : is found below the skin and between internal organs. It
contains fats and helps to store fats.
27. D. Nervous tissue
Nervous tissue helps to carry messages from one part of the body
to the other and responds to stimuli. It is found in the brain, spinal
cord and nerves. It consists of nerve cells called neurons.
Neuron (Nerve cell) : It has a cell body containing a nucleus and
cytoplasm. It has hair like structures called dendrites and a long part
called axon having nerve endings. The axon has a protective covering
called myelin sheath. The neurons are joined together to form nerve
fibres. The junction between two neurons is called synapse.
