This document discusses key concepts of evolution including the history of evolutionary theories from creationism to modern ideas like punctuated equilibrium. It covers Darwin and Wallace's model of natural selection and how environmental pressures can lead to speciation. The fundamentals of evolution are explained including variation, inheritance, selection over time. The role of tectonic plate movement in genetic isolation and speciation is described. Various forms of evidence for evolution are listed such as the fossil record, present-day examples, and molecular clocks using mitochondrial DNA.
BIODIVERSITY AND EVOLUTION
POPULATION
IMPORTANT ASPECTS OF POPULATION
BIRTH- Natural process in which parents give rise to new offspring.
DEATH- Reduces the number of existing individuals in a population.
MIGRATION- Movement of individuals into or out of the population.
IMMIGRATION- Movement of individuals into the population.
EMIGRATION- Movement of individuals out of the population.
PATTERNS OF POPULATION GROWTH
BIOTIC POTENTIAL- Maximum reproductive capacity of an organism given that the resources are unlimited.
EXPONENTIAL GROWTH- Capacity of a population to increase continuously without showing any signs of stabling or declining.
FACTORS THAT AFFECT POPULATION GROWTH OR SIZE
LIMITING FACTORS
-control the growth, size, and distribution of organisms
COMPETITION
ABIOTIC FACTORS
PREDATOR-PREY RELATIOSHIP
POPULATION DENSITY
EXTINCTION
Some famous mass extinction events

Energy from Volcanoes ppt. is the next topic/ lesson from grade 9 LM Module 1 Quarter 3. The presentation is a discussion guide for teachers about geothermal energy and gives video suggestions in order for the students to understand the lesson well especially in showing how geothermal energy is harnessed. Feedbacks, reactions and suggestions are very much welcomed. Thanks!

artificial selection, also called "selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection.
A public lecture on "Why all the fuss about Darwin and Evolution?" by Dr. Eugenie Scott, Executive Director of National Center for Science Education, on the campus of California State University, Fresno, presented on December 2, 2009. The event was sponsored by the campus Consortium for Evolutionary Studies.

This is the instruction sheet for my MYP year 4 chemistry unit on thermal energy. It's a Vernier lab, which means it requires proprietary probes from the Vernier company. I have adapted the company's original document to highlight key steps for my students.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
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.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
