Solution
please split the questions and ask. it was too lengthy to answer so all are in short.
1. Explain the basic characteristics that are common to all living things.
The fundamental characteristics of all living beings are growth, reproduction. All are made up of
cells, they adapt and respond to the environment. They all obtain and utilize energy. Though all
these are in common, they have different cellular organization.
2. Describe the levels of organization of life.
The various levels of organization of life include organelles, cells, tissues, organs, organ systems,
organisms, populations, communities, ecosystem and biosphere. They are in the chronological
order starting from the simplest form to the most complex one.
3. Distinguish among the three domains of life and kingdoms.
Three domain system introduced by carl woese divides cellular forms into three domains- archae,
bacteria and eukaryotes. It mainly separates archae from prokaryotes based on their 16sRNA
differences. This classification is above the kingdom level.
The five kingdom system has prokaryotes without membranes placed under Monera, eukaryotes
are placed into 3 kingdoms plantae, fungi and animalia. Protista are a separate kingdom
consisting of diversified algae and others which does not come under other groups
4. Explain the process of natural selection
Charles Darwin proposed the natural selection in his theory of evolution. Natural selection is a
process by which the organisms which are adapted to the environmental conditions and survive
in them. Shortly said as “survival of the fittest”. They transfer the genetic traits to further
generations making them more dominant while those who cannot survive get eliminated.
5. Identify the components of the scientific method.
Scientific method is a planned method which helps scientists in answering or solving a problem.
It consists of 6 components. 1. Purpose or question of research, 2. Research to find more
information on the question, 3. Hypothesis after getting preliminary information, 4. Experimental
design of the question, 5. Analysis of the results, 6. Conclusion of the experiment.
6. Contrast ionic and covalent bonds.
Covalent bonds are less polar than ionic bonds.Covalent bond is a chemical bond formed
between two non-metals .

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.

Editor's Notes
Rules in Naming Elements Naming the elements is a difficult task. The individual or the group that discovered it gets the privilege of naming it. Here are some of the ways on how they named the elements as we get it today. These are from IUPAC or International Union of Pure and Applied Chemistry.
Based on the properties of the Elements. Elements have been named based on their properties or attributes. For example, phosphorus got its name from the Greek word “phosphoros,” which means lightning bearer. It is due to the fact that phosphorus, when burnt, gives off a very bright light.
Based from its origin/ore or mineral substance Elements are also named based from its origin mineral or what we call as ore. Elements are usually found mixed with other elements through rocks called minerals. For example, aluminum is named after its ore alum, from where it was first found. Alum is a combination of aluminum, potassium, and sulfates.
Based on its Discovery Some of the elements are named based on the way it was discovered. For example, helium was named helium when they discovered it accidentally when they are studying a solar eclipse and saw an unknown signal in their graphs. They named it after the Greek word for sun or helios.
Based on mythological figures or astronomical object Some of the elements are named after mythological figures, like Thorium from the name of the Norse god Thor or the god of thunder.
Based on places they represent. Most recently discovered elements are named after locations that they represent. For example, Yttrium is named after Ytterby, Sweden, as they are found in a mine in that location. Berkelium is named after Berkley, California, where this element is discovered.
Based on scientist’s name Some of the elements as well are named in honor of famous scientists like Einsteinium in honor of Albert Einstein.
