Chapter 5 Reading Questions
1. Explain the biological significance of the Dung of the Devil.
Extracts from the plant have strong antiviral properties that are very helpful for fighting disease.
2. Give 2 reasons conservation of biodiversity may be beneficial to our health.
There may be some organisms that can provide health benefits, such as the Dung of the Devil. Also, greater biodiversity allows for greater stabilization of the climate, which is necessary for our well-being.
3. Give 3 examples of how natural substances have been used to treat disease.
The rosy periwinkle is used to treat childhood leukemia and Hodgkin’s disease. The mayapple is the source of two anti-cancer drugs. Other medicines come from invertebrates such as sponges, corals, and sea squirts.
4. Which has more biodiversity a carefully tended lawn or a small plot of untended land? Explain.
A small plot of untended land has greater biodiversity, since there is a greater variety of species there than on the well-kempt and uniform lawn.
5. Define species.
A species is a group of organisms that is distinct from other groups in terms of characteristics, and that can breed with each other.
6. Approximately how many species have scientists named? How many species are estimated to live on Earth?
About 2 million have been named, and about 10 million are thought to live on Earth.
7. Compare and contrast species richness and species evenness. Use an example to explain.
Species richness – the number of species in a given area, such as a pond or a tree
Species evenness – the proportion of the number of species in an ecosystem
Two communities may have an equal species richness, but one community may be dominated by one species, while the other may have an equal number of each species.
8. How are species phylogenies determined?
They are determined by the similarity of different species (morphology and behavior)
9. List the classification system from the most broad to the most specific.
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
10. Speciation is an example of microevolution or macroevolution? Explain.
Speciation is an example of macroevolution. Both result in the creation of new species. Microevolution is small-scale changes in a species that may eventually result in speciation.
11. Explain 2 ways mutations may occur. Are they good or bad? Explain.
Mutations may occur by UV radiation. It can also occur through mistakes made while DNA is copied.
12. Explain how recombination occurs.
It is the switching of one small part of a chromosome with another during meiosis.
13. Give 2 examples of how humans are purposefully or inadvertently directing evolution of organisms.
The breeding of plants and animals for human use is done purposefully. The evolution of weeds after being sprayed with herbicides is inadvertent.

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.

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.
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
