Introduction to Mitosis
What is Mitosis?
Mitosis is the division of a single parent cell, resulting in two daughter cells.
Usually happens in ordinary tissue growth.
What are the Steps of Mitosis?
The steps of mitosis are:
Prophase, Metaphase, Anaphase, Telophase
Remember: P-M-A-T
Prophase
The first stage of mitosis, when the chromosomes become visible and the nuclear membrane disappears.
Metaphase
The chromosomes now attach to spindle fibers with their pairs.
Anaphase
The chromosome pairs separate and move to the opposite sides of the cell.
Telophase
The final stage of mitosis, when the separated chromosomes reach the opposite poles of the cell and a new nuclei forms around the new chromosomes around the two daughter cells.
The cell proliferation will generally decrease with the differentiation of cells, and most cells in adult animals are blocked in the G 0 phase of the cell cycle.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

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.

2. What is Mitosis?
• Mitosis is cell division which begins in
the fertilized egg (or zygote) stage and
continues during the life of the organism
in one way or another. Each diploid (2n)
daughter cell is genetically identical to the
diploid (2n) parent cell.
3. Walther Flemming (1843 – 1905)
• Described the process of cell division in 1882
and coined the word ‘mitosis’
• •Also responsible for the word “chromosome’
which he first referred to as stained strands
• •Co-worker Eduard Strasburger named the
mitotic stages ‘prophase, metaphase,
anaphase, telophase’ in 1884

Zellsubstans, Kern
und Zelltheilung

Nucleus, and Cell-
Division)

process of mitosis, 1882
6. Why Do Cells Undergo Mitosis?
• Mitosis is exact nuclear division. The DNA in the parent cell is
copied exactly and then the cell nucleus divides exactly so
each of the two daughter cells has the same kind and number
of genetic base pairs arranged in chromosomes as the parent
cell.
• Mitosis is necessary because when cells reach a surface area
to volume ratio that is too small relative to the rate of
diffusion of nutrients and water into the cell, and thus the
nutritional demands of the cell cannot be met.
• In order to address this, the cell undergoes mitosis to form
two identical, but smaller cells, which increases the surface
area to volume ratio, and thus the rate of diffusion can meet
the nutritional demands of the entire cell.
7. Interphase
• The cell prepares for division
• Animal & Plant Cell
– DNA replicated (copied)
– Makes new organelles (synthesis)
– Cell increases in size (growth)
12. Metaphase
• The cell prepares chromosomes for division
• Animal & Plant Cell
– Chromosomes line up at the middle of the cell
– Spindle fibers attach to chromosomes at the
centromere
– SHORTEST phase of mitosis
14. Anaphase
• The chromosomes divide
• Animal & Plant Cell
– Spindle fibers pull chromosomes apart
– ½ of each chromosome (called chromatid) moves
to poles of cells
15. Telophase
• The cytoplasm divides
• Animal Cell
– DNA uncoils & appears as chromatin again
– 2 nuclei form
– Cell membrane pinches in to form the 2 new daughter cells
• Plant Cell
– DNA uncoils & appears as chromatin again
– 2 nuclei form
– New cell wall forms between two nuclei to form the 2 new
daughter cells
