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

A Strategic Approach: GenAI in EducationPeter 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. Are Plants Heterotrophic or Autotrophic?
Plants are autotrophs
Autotrophs- they create their own food
3. Aboveground parts of the plant and their
Function:
Aboveground: Shoots
Leaves stems: produce food by photosynthesis
Flowers: reproduction
Aboveground: steam and leaf
Major stem
Secondary stems branch off
Terminal bud: shoot tip
Auxiliary bud: location of secondary stem growth
Petiole: stalk attaching leaf to stem
Node :location on stem of left attachment
4. Belowground portions of the plant and
their functions
Belowground: roots
Absorb water and minerals
Store food
5. Apical meristem
located on the top of the plant and on the bottom of the root. It is where cell
division is taking place and the plant is growing vertically.
Contain unspecialized cells
Lengthen shoots and roots
Located at the tip of the shoot and the bottom of the root
6. Lateral Meristem
located around the plant. It is where cell division is taking place and the plant
is growing hora

Cylindrical arrays of cells zontally.
7. Eudicots and Monocots
Eudicots
Have two cotyledons
Vascular tissue is arranged n a ring
Monocots
Have one cotyledons

8. Vascular Tissue
Vascular tissue: transport water and nutrients
Xylem
transports water
Conducts water
2 cells: vessel member and tracheid's
dead at maturity
Interconnected for vertical and lateral water movement
Phloem
Transport nutrition (food)
Conducts sugar
One cell: sieve member
Alive at maturity
Connect end to end
Helper cell: companion cells

9. Leaf Tissues
Mesophy II
Photosynthetic tissue between the epidermis
2 rows, columnar shaped
Contain 80% of chloroplasts
Spongy: attached to lower epidermis

Upper and lower epidermis secrete waves into the outer surface forming the caticle
Helps conserve water and protects
10. Stomata and Guard cells
Guard cells
Regulate the gas exchange and water loss
Control stomata opening and closing
Contain chloroplast
Expand and contract with water gain and loss
Stomata
Pores in the lower epidermis
Allow water and gas diffusion
Help cool the leaf
Are simply the holes in the leaf where gas exchange and water loss take place
11. Root Structure
Primary root: main root
Tip is the apical meristem
Contains the root cap
Protects the root with slime

Secondary roots (lateral): branch off from main root
Root hair: small extensions
12. Flower Structure
Receptacle: swelling at tip off peduncle
Attachment for other flower parts
Petals: inside of sepals

Ovary becomes fruit
15. Pollination and fertilization
Pollination: pollen grains released from an anther land on a stigma
Pollination is the delivery of pollen to the female structure of the plant
Fertilization: fusion of egg and sperm
actual coming together of the sperm and the egg.
16. Adaptation of life of land

Region of Elongation: cells lengthen and widen
Region of maturation:maturecells differentiate into different types
22. Cohesion-tension theory of water
Water moves from high to low concentration due to osmosis
Transportation occurs at all plant surface exposed to air
Parts of xylem cells in tension
Extends from leaves to steam to roots
23. Phototropism
When plant adjust the rate and direction of growth in response to light
Results in more efficient photosynthesis
