The document discusses adaptations and populations. It defines a habitat and environment, and explains that adaptations enable organisms to survive in their environment. Examples of adaptations in camels, polar bears, cacti, palm trees and fish are provided. The document also notes that population size of a species can be affected by factors like light, water, disease, predation or competition for food. Competition affects where a species lives, the size of its population and how distributed the population is.
The reproductive system is the human organ system responsible for the production and fertilization of gametes (sperm or eggs) and, in females, the carrying of a fetus. Both male and female reproductive systems have organs called gonads that produce gametes.
The reproductive system is the human organ system responsible for the production and fertilization of gametes (sperm or eggs) and, in females, the carrying of a fetus. Both male and female reproductive systems have organs called gonads that produce gametes.
The male and female reproductive systems develop initially embryonically "indifferent", it is the product of the Y chromosome SRY gene that makes the "difference".
♂ - Male ♀ - Female
The reproductive organs are developed from the intermediate mesoderm.
The permanent organs of the adult are preceded by a set of structures which are purely embryonic, and which with the exception of the ducts disappear almost entirely before the end of fetal life.
These embryonic structures are the mesonephric ducts (also known as Wolffian ducts) and the paramesonephric ducts, (also known as Müllerian ducts). The mesonephric duct remains as the duct in males which gives rise to seminal vesical, epididymes and vas deferens, and the paramesonephric duct as that of the female.
Importantly its sex chromosome dependence, late embryonic/fetal differential development, complex morphogenic changes, long time-course, hormonal sensitivity and hormonal influences make it a system prone to many different abnormalities.
Gonads:
Gonads Produce eggs and sperm cells, transport and sustain egg and sperm cells, nurture developing offspring, and produce hormones.
The gonads, ovary or testis, also develop in the intermediate mesoderm.
They originally form as swellings that lie just ventral to the anterior mesonephric kidney.
A mullarian duct also develops in the intermediate mesoderm near the mesonephric duct.
Due to fusion or failure of 1st ridge to differentiate, some vertebrates (agnathans, some female lizards & crocodilians, & most female birds) have a single testis or ovary.
Hormones cause differentiation of early gonads into either testes or ovaries.
As males develop the mesonephric duct makes connection with the testis as the primary sperm conducting duct, and the mullerian duct is lost.
Structure and function of adrenal glandsMoses Kayungi
Structure and function of adrenal glands
• Anatomically, the adrenal glands (suprarenal) are located in the thoracic abdomen situated 'on' top of the kidneys one on each side, specifically on their anterosuperior aspect.
• They are surrounded by the adipose capsule and the renal fascia
• They consist of two parts,
The outer cortex
The inner medulla.
Adrenal Cortex
• The adrenal cortex is devoted to the synthesis of corticosteroid hormones from cholesterol.
It completes the hypothalamic-pituitary-adrenal axis
The source of cortisol and corticosterone hormones
• The cortex is divided into three zones, or layers.
• This division is sometimes referred to as ‘functional zonation”
Zona glomerulosa
Zona fasciculata
Zona reticularis
Adrenal Medulla
• The adrenal medulla is the core of the adrenal gland, and is surrounded by the adrenal cortex.
• The chromaffin cells of the medulla are the body's main source of the circulating catecholamines, adrenaline (epinephrine) and noradrenaline (norepinephrine
Blood supply to Adrenal Gland
• Although variations of the blood supply to the adrenal glands (and indeed the kidneys themselves) are common, there are usually three arteries that supply each adrenal gland:
The superior suprarenal artery is provided by the inferior phrenic artery.
The middle suprarenal artery is provided by the abdominal aorta.
The inferior suprarenal artery is provided by the renal artery
• Venous drainage of the adrenal glands is achieved via the suprarenal veins:
The right suprarenal vein drains into the inferior vena cava.
The left suprarenal vein drains into the left renal vein or the left inferior phrenic vein

Climate change and biodiversity are closely linked: climate change has severe direct and indirect impacts on biodiversity and is predicted to be a dominant driver of future biodiversity loss; at the same time, the loss of biodiversity magnifies the adverse effects of climate change.

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.
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

1. Adaptations
1. A habitat is the place in which an
organism lives
2. The environment is the conditions in
which the organism lives
3. Organisms have certain features which
enable them to survive in their
environment. These are called
adaptations
9. Populations
1. The size of the population of a species
can be affected by the amount of light,
water, disease, predation or
competition for food
2. In the wild competition affects the :
• Location of a species – where it lives
• Size of a species – how big the
population is
• Distribution of a species – how spread
out the population is
