DanWater ecosystems can be divided into three main categories: plankton, nekton, and benthos. 97% of the Earth is covered in salt water and 3% in fresh water. Freshwater ecosystems include rivers and streams, which are running water ecosystems, and lakes and ponds, which are standing water ecosystems. Ocean ecosystems contain several zones from the intertidal zone near the shore to the deep abyssal zone. Where salt water and fresh water meet is called an estuary, which contains a mix of both and usually salt marshes.

homeostasis
Homeostasis refers to the maintenance of a stable internal environment in the body despite changes in the external environment. It is important for organisms to regulate their internal environment to maintain independence from external environmental fluctuations. The human body regulates many internal factors through the nervous and renal systems. The nervous system uses the parasympathetic and sympathetic systems to regulate responses, while the renal system filters blood and reabsorbs necessary molecules through nephrons in the kidneys to control fluid and electrolyte balance.
Bodies of water
Power Point done and used to teach 2nd and 3rd Graders in Sciences. (Bodies of water- seas-oceans...)
Bodies of water
The document discusses different types of bodies of water on Earth. It states that about 3/4 of Earth's surface is covered by water, but only 1/2 cup out of a gallon jug represents the amount of fresh water. The largest oceans are the Pacific, Atlantic, Indian, and Arctic. Lakes are bodies of water surrounded by land, and the Great Lakes are located in Michigan. Rivers contain fresh water and flow into larger bodies of water. Ponds and streams are smaller than lakes and rivers.
final project
The document discusses four projects the student completed over the course of a semester. The first was a biography presentation where they shared photos from their life. The second was a group project where they interviewed local business owners about accessibility for disabled people and created public service announcements. The third was putting on a play based on a Disney movie for different school levels. The student enjoyed working with classmates and learning new skills through each project over the semester.

Section 1
A force is defined as a push or pull that can be measured in Newtons. Multiple forces can act on an object simultaneously, and the combination of all these forces is called the net force. An unbalanced net force causes an object to change its motion by starting, stopping, or changing direction, while a balanced net force where forces are equal on both sides results in no movement. The document then introduces an activity involving balloon rocket races.

3GPP LTE-A Standardisation in Release 12 and Beyond - Jan 2013 Eiko Seidel, C...
Quite some time ago major improvements have been made to LTE with LTE-Advanced as part of 3GPP Release 10. Unquestionably, LTE-A will be the leading global 4G standard fulfilling the defined ITU-R requirements [1] on IMT-Advanced such as peak data rates beyond 1Gbps. While further enhancements to LTE-Advanced have just been completed in 3GPP Release 11, the new technology trends become visible to serve the continuously growing traffic demand. This White Paper, based on Nomor’s attendance of 3GPP, provides an outlook on 3GPP standardisation for the forthcoming years. Besides a summary of general trends and a projected release schedule, it includes an overview of the work and study items of Release 12 in the Radio Working Groups. New key technologies that Release 12 will address are: Small Cell Enhancements, a New Carrier Type, 3D-MIMO Beamforming, Machine-Type-Communication, LTE-WiFi Integration at radio level and Public Safety incl. Device-to-Device communication. While the completion of Release 12 is expected mid of 2014, deployments might be seen around the end of 2015 and later. NoMoR is active in different related research projects and offers consultancy services for related research, standardisation, simulation, early prototyping and technology training.

Google's Android operating system, which is used in Motorola and other smartphones, grew to a 17% market share globally in the third quarter while Nokia's Symbian remained the leader. This growth positions Google well as smartphones are projected to surpass computers for web browsing.
Lesson 1
The document summarizes Britain imposing taxes on its colonies through various acts of Parliament in the 1760s-1770s, which angered American colonists and led to protests. The Stamp Act of 1765 placed a tax on printed materials and was opposed by Patrick Henry and the Stamp Act Congress. The Sons of Liberty and later the Daughters of Liberty organized boycotts of British goods in response to the Townshend Acts taxing imported goods.
A fieldtrip through the ladse network
LADSE is a special education cooperative that Jonathan Adamczewski provided a tour of their network for. The network begins at the control room where the original phone lines entered the building and now serves as the entry point for phone and internet connections. From there, the connections run through a series of switches and Ethernet cables to hardwire the building and connect all the computers, printers, and phone systems. The servers in the server cabinet store all shared applications and storage. Wireless access points provide internet coverage throughout the building to ensure no dead spots. Even small networks like those in off-site centers consist of basic components like wireless routers, switches, and hardwired connections to make everything work together optimally.
Policies and problems
The document outlines key issues and policies from Julia Gillard and Tony Abbott during the 2010 Australian federal election.

Lesson 3
A biome is a major land ecosystem defined by its climate and characteristic plants and animals. There are six major land biomes: desert, tundra, taiga, tropical rainforest, temperate rainforest, and grasslands. Each biome has adaptations that allow its plants and animals to survive within a particular climate and habitat.
Lesson 5
The document discusses weathering, erosion, and deposition. Weathering is the process by which rocks and materials break down. There are two types of weathering - physical weathering caused by temperature changes and chemical weathering caused by chemicals. Erosion is when weathered rock is moved from one place to another by forces like gravity, water, wind, etc. Deposition is when eroded materials are deposited in another location. Landforms like meanders and sandbars are created through these geological processes.

Lesson 3
Volcanoes are commonly found along tectonic plate boundaries like the Ring of Fire around the Pacific Ocean. Magma is melted rock below the Earth's surface that becomes lava when it reaches the surface. Different volcanic features like dikes, sills, and batholiths are formed by magma hardening in vertical cracks or between layers of rock. The three main types of volcanoes are shield, cinder-cone, and composite volcanoes which are distinguished by their shape and eruption patterns. Island chains like Hawaii are formed as tectonic plates move over stationary hotspots of magma or along island arcs where subduction causes magma to rise upward.

A River is a living entity much as an artery in human being. So management of diseased river is also on similar lines as we manage coronary angina or any other diseased blood vessel.
Aquatic ecosystemsppt
There are several types of aquatic ecosystems including freshwater ecosystems like lakes, rivers, and wetlands as well as marine ecosystems. Aquatic ecosystems are important as they support biodiversity, provide breeding grounds, act as buffer systems, and are part of the water cycle. They can be altered by both natural processes like succession over time as well as human impacts like water pollution, excessive fertilizer use, industrial waste, and other forms of waste disposal.
Water Distribution on Earth
The document discusses the distribution of water on Earth. It notes that:
- 71% of the Earth's surface is covered in water, but 97% of that water is salty ocean water, leaving only 3% as freshwater.
- The major stores of freshwater are glaciers/ice (2.15%), groundwater (0.61%), and freshwater lakes (0.009%). Smaller amounts are found in the atmosphere, inland seas, soil moisture, and rivers.
- Water is distributed through the hydrologic cycle and, while it changes forms, the amount of water on Earth remains fairly constant over time as it is recycled.
Q2 Module 2 (Earth's Water).pptx
This document provides definitions and descriptions of various aquatic ecosystems. It defines marine ecosystems as containing 97% of the planet's water and covering 71% of the Earth's surface.

Finally, it lists several uses of water.
Unit 3 water
This document discusses various topics related to physical geography of water:
- Water is found on Earth as oceans (97% of water), seas, rivers, lakes, groundwater, and glaciers. It circulates through the water cycle.
- Rivers start from springs, lakes, glaciers or rainfall and flow into larger rivers and basins, providing water and resources for human uses.
- Oceans and seas contain almost all liquid water and provide food, resources, tourism, and transport but are threatened by pollution and overuse.
- Currents, tides, and waves influence ocean water and climate while lakes form inland from precipitation or glaciers, with the largest including the Great Lakes and Lake Victoria.
Freshwater Ecosystems
Freshwater ecosystems include rivers, streams, lakes, ponds, and wetlands. They make up a small fraction of the Earth's total water but support a diversity of habitats and species. Rivers and streams flow with cold, oxygen-rich water and can broaden and slow downstream. Lakes and ponds differ in size, with ponds being smaller and sometimes seasonal. Wetlands, including marshes and swamps, act as filters to clean water and protect shorelines from erosion. Freshwater ecosystems face threats from pollution and development.
Aquatic ecosystem and water pollution
Aquatic ecosystems can be freshwater like lakes, rivers, and wetlands, or marine water like oceans. They contain a variety of organisms adapted to different zones based on factors like sunlight, temperature, and oxygen levels. Aquatic ecosystems are important for biodiversity, breeding grounds, and being part of the water cycle, but are threatened by pollution, nutrient runoff, and other human impacts that can cause eutrophication and loss of species. Proper management of fertilizers, waste, and industrial discharges is needed to protect these fragile environments.

This document discusses the diversity of rivers. It begins by introducing rivers and outlining their key characteristics, including their flow downstream powered by gravity. It then describes the river ecosystem, including populations that live on the surface, in deep areas, estuaries, marshes, and swamps. The importance of rivers is highlighted as providing habitat, fresh water, flood storage, renewable energy, aquaculture, and transportation. River ecosystem disruption from waste disposal, industrial activities, agriculture, and toxic dumping is examined. The effects of degradation include threats to flora and fauna as well as impacts on climate, oxygen levels, and human activities. The document concludes by discussing conservation efforts like habitat restoration, environmental education, enforcement of laws,
Water
Water is used for agricultural, industrial, and domestic purposes. Agricultural uses include irrigation of crops, which requires large amounts of lower quality water. Industrial uses involve both consumptive processes that use water, like manufacturing, and non-consumptive processes like cooling. Domestic water is used for drinking, bathing, cleaning, and other household activities. The quality of water needed depends on its intended use.
Block 3 Water in the Ecosystems
There are two main types of aquatic ecosystems: freshwater and saltwater. Freshwater ecosystems include lakes, rivers, and wetlands, and are characterized by factors like light, dissolved gases, and temperature. Saltwater or marine ecosystems make up the oceans and coastal waters, and are regulated by light, salt levels, temperature, and currents. They contain a diversity of life including phytoplankton, invertebrates like jellyfish and coral, and vertebrates like fish and marine mammals. Estuaries are transitional ecosystems where freshwater mixes with saltwater from the ocean.
Water ecosystems lcr
Water ecosystems can be divided into saltwater and freshwater. Saltwater ecosystems include oceans, seas and some lakes, and contain animals like fish, sharks, whales and penguins. Freshwater ecosystems contain very little salt and include rivers, streams, lakes and ponds, and are home to animals such as trout, otters, bullfrogs and turtles. In both saltwater and freshwater ecosystems, plants and animals are typically found in shallow, sunlit areas near the surface.

It also discusses the three main marine biomes: oceans, coral reefs and estuaries. Specific examples of aquatic life are given for Pakistan, including the Indus River dolphin, trout fish, sea snakes and turtles.
Why is water important bkmw
Water is essential for all life on Earth. The human body is made up of 45-60% water and water is needed for critical functions like regulating body temperature and transporting nutrients. While the oceans hold the vast majority of Earth's water, less than 1% of water is available as freshwater in rivers, lakes, and groundwater. Given water's unique properties as a solvent and its role in biological and industrial processes, access to clean water is necessary for drinking, sanitation, agriculture, and electricity generation.

Greece has a long history dating back to ancient Greek city-states like Athens that developed one of the first known democracies. The Byzantine Empire carried on Roman traditions for 1000 years after the Western Roman Empire fell. Today, Greece has a president and prime minister, with over 98% of Greeks practicing Greek Orthodox Christianity. Agriculture remains an important industry, with farmers growing crops like cotton, wheat and olives, and Athens is the capital and largest city despite air pollution issues.
Section 5
Rockets are able to lift off into space due to Newton's 3rd law of motion, which states that for every action force there is an equal and opposite reaction force. Satellites are objects that orbit other objects in space, such as planets, due to centripetal force keeping them in orbit around the larger object. Satellites do not fall back to Earth because the horizontal velocity of their orbit around the Earth is great enough to counteract gravitational pull, allowing them to remain in a continuous orbit.

It outlines four principal types of laws: statutory laws passed by legislatures, common laws based on precedents, administrative laws created by government agencies, and constitutional laws based on the U.S. Constitution. It also discusses some key rights in the U.S. legal system such as the right to a lawyer, right to bail, right to a jury trial, presumption of innocence, right against self-incrimination, right to cross-examine witnesses, right to accurate evidence, and right to appeal a conviction.
Lesson 4
The document describes slavery in northern and southern colonies. In the north, some slaves worked on farms while most worked in towns and cities, where they had more opportunities than southern slaves but laws still limited their rights. In the south, most slaves worked on large plantations, where some showed farmers how to raise rice. Southern slave owners could sell slaves and slaves created instruments to preserve their culture and send messages. The document also mentions slaves resisting slavery by working slowly, breaking tools, and staging rebellions like the Stono Rebellion.
Lesson 3
The document discusses various aspects of everyday life in the colonies, including education, religion, reading, and meals. It states that education was important and most schools were one room, teaching basics like reading, writing and arithmetic. It also discusses the religious landscape, with religion being important and events like the Great Awakening. Reading was a form of entertainment and important publications included the Boston News-Letter and Ben Franklin's Poor Richard's Almanac. Meals in the colonies centered around foods like corn, stew, bread and desserts.
Lesson 2
The document discusses different types of settlements in colonial America:
- Cities like Philadelphia where Benjamin Franklin established the first newspaper, public library, and volunteer fire department.
- Puritan towns in Massachusetts that were self-sufficient with crops and trade between communities. They had a common area for livestock.
- Southern plantations that grew cash crops like tobacco with slave labor under wealthy owners and managers.
- Family farms where everyone worked hard to grow their own food for survival.
Lesson 1
The document discusses life for young workers and colonial economies. It states that an apprentice learns skills from experienced workers, artisans made things by hand, and most artisans were boys though some girls learned sewing and cooking. It then outlines the economies of the New England, Middle, and Southern colonies, which centered around fishing/whaling, farming and valuable minerals, and cash crops respectively. Finally, it discusses colonial trade routes, mentioning triangular routes and cities that were important trading centers and involved in the slave trade.
Lesson 1
The document discusses minerals and rocks. It defines minerals as solid, natural materials made from nonliving substances in the ground and made up of elements. It describes properties of minerals such as luster, hardness, cleavage, and fracture. It also discusses the shapes of minerals including crystals and gems. The document then defines rocks and describes the three main types: sedimentary rocks form from compressed sediments, igneous rocks form when lava cools and hardens, and metamorphic rocks form from changes to sedimentary and igneous rocks under heat and pressure.
Section 1
A force is defined as a push or pull that can be measured in Newtons. Multiple forces can act on an object simultaneously, and the combination of all these forces is called the net force. An unbalanced net force causes an object to change its motion by starting, stopping, or changing direction, while a balanced net force where forces are equal on both sides results in no movement. The document then introduces an activity involving balloon rocket races.
Lesson 4
An earthquake is the sudden movement of the Earth's crust caused by rock that is stuck together slipping suddenly. The epicenter is where the slipping rock begins and is the point where seismic waves start spreading out. Earthquakes typically occur along tectonic plate boundaries. An earthquake is measured on the Richter scale based on the magnitude of energy released at the epicenter, while the Mercalli scale measures the effects felt by people.
Lesson 2
The document discusses plate tectonic theory, including how geologists proposed that Earth's crust is made up of plates that move over time. It introduces Alfred Wegener's theory of continental drift, which proposed that continents move apart, and how fossil evidence later helped support this idea. It also discusses how plate tectonics can explain seafloor spreading through processes like magma formation at mid-ocean ridges. Additionally, it examines how mountain formation can occur through the compression and shearing of tectonic plates.
2011 2012 school calendar - updated june 23, 2011
This document contains a school calendar for the 2021-2022 school year. It lists important dates such as the first and last day of school, holidays, early dismissal days, conferences, and other school events. The calendar shows the months of August through June with notes about what is happening each month such as the start of each academic quarter, picture days, and vacations.
Chapter 5 Lesson 1
The document discusses various landforms and features of the Earth's surface and interior. It defines a landform as a physical feature on the Earth's surface and describes features of the ocean floor such as ocean basins, continental shelves, slopes, canyons, and rises. It also discusses how elevation and topographical maps are used to map Earth's landforms. Finally, it outlines Earth's major layers including the atmosphere, hydrosphere, crust, mantle, outer core, and inner core.
Chapt 5 sect 1
The document discusses the structure and composition of the United States Congress. Congress is made up of two chambers - the Senate and the House of Representatives. The Senate has 100 members with two Senators per state who each serve 6-year terms. The House of Representatives has 435 members who are elected based on state population to 2-year terms. The document also outlines qualifications, salaries, benefits, and election cycles for Senators and Representatives.
Section 1
Canada has several physical features including coastal mountains, the Rocky Mountains, and the Canadian Shield region of rocky uplands. The climate varies regionally from humid continental in central and eastern Canada to marine west coast in southwest Canada, with tundra and ice cap climates in the far north. Canada has abundant natural resources such as fisheries along the coasts, agricultural production including wheat and cattle, and various minerals including nickel, zinc, uranium, lead, copper, gold, silver, coal, and the world's largest deposit of potash in Saskatchewan used to make fertilizer. Coniferous forests provide lumber and pulp used to make paper and newsprint.
Lesson 1
The document discusses the water, carbon, and nitrogen cycles. It explains that in the water cycle, water is constantly evaporating from surfaces, condensing in the atmosphere, and falling as precipitation to then run off or be absorbed in a repeating cycle. The carbon cycle involves carbon being exchanged between living things, the atmosphere, oceans, fossil fuels, and rocks. The nitrogen cycle traps nitrogen gas from the air as compounds in the soil through fixation by bacteria or lightning, which are then used by plants and decomposed or released through denitrification.
