(Crops may at some point also be weeds) Weed disadvantages • Reduces crop yield – weeds and crops have to share resources such as light, water and nutrients • Reduces crop quality and health – increases moisture and disease levels • Delay harvesting – conservation of moisture may delay ripening Beneficial effects of weeds • Valuable indicators • Help against erosion
decade: that is bioethanol and biodiesel. Bioethanol is based on sugar, extracted from sugarcane and beet, or starch, which mainly comes from maize, wheat or cassava. Starch- based crops must be first converted into sugars in the saccarification process, which requires substantial volumes of enzymes to turn starch into sugars (Soetaert, W. 2008). The starchy products represent only a small percentage of the total plant mass. Other plants' building blocks like cellulose and lignin are currently not being used to make biofuels as there is not a commercial viable production method for making ethanol form cellulosic biomass (FAO, 2008). Biodiesel is based on the oil crops, such as rapeseed in Europe and soybean in the USA and Brazil. In tropical regions, biodiesel feedstock can also be sourced from palm, coconut and jatropha oils, but these are currently not major feedstock for biodiesel. Biodiesel is produced
Extended Essay Research Question: To What Extent Does a Plant Based Diet Lower the Risk of Coronary Artery Disease? Subject: Biology Word Count: 3482 Abstract: Because there has been much debate over whether plant based diets are beneficial or not, I’m willing to learn more about it and since there’s eligible data available on the effects of vegetarian/vegan diets on cardiovascular diseases, my research question is formed accordingly: To what extent does a plant based diet lower the risk of coronary artery disease? The importance of this study lies in my own curiosity and my desire to acquire further knowledge on the prevention and treatment of coronary artery disease.
Her friend, Les, didn't like to use any energy at all. He walked to school, read books instead of watching TV, played the trumpet instead of Guitar Hero, and turned off the lights anytime he left a room. Then one evening, there was a power outage. The lights went out, the TV turned off, and everything became very quiet. Jules became very upset, and quite scared. She couldn't do anything that she wanted to do. She didn't think she could survive. Meanwhile, Les didn't seem to mind at all. He was able to light a few candles and he could still read his books, practice his trumpet, and hang out and play cards with his family. The two friends then realized that there was a big difference in their lifestyles and the amount of energy they used. So Jules decided she should figure out how much energy Les used and then compare her energy consumption to how much she really needed. To do this, they figured out how much energy Jules was using for entertainment, light, heating and
The network of artesian wells provides cattle with water. Natural zones The wet forests also called the rainforests occupy the narrow coastal region in the east. In the west they give place to grasslands with some trees called savannas. Farther west the trees disappear and the savannas give place to the bushlands. The real desert occupies the centre of the Western Plateau. In the very southwest there are thin forests of evergreen trees. Plants A rich variety of plant can be found in the natural landscapes of Australia. A lot of species can be found in wet tropical forests in the north and in temperate rainforests in the south. The biggest family of the native plants is the myrties. They include more than 500 species of eucalyptus, or gum trees. Only the big river red gum is seen everywhere. These can be found beside rivers and dry riverbeds. Some gum trees are valuable timber species and have been cut down for many years
The ship spilt only 5% of the oil spilt that year, and oil is just one of many pollutants that people dump into the water every year. Every year, 14 billions pounds of sewage, sludge, and garbage are dumped into the world's oceans. 19 trillion gallons of waste also enter the water annually. The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another. For many years, chemicals were dumped into bodies of water without concern. While many countries have now banned such behavior, it continues to go on today. As the world has industrialized and its population has grown, the problem of water pollution has intensified. The simple fact that millions of people live along coastlines and near rivers means that these bodies of water are likely candidates for heavy and destructive pollution.
climbing, fishing, hunting or skiing. The only big city in the Rockies is Denver. Lakes The Great Lakes are a group of five large lakes in North America. They are the largest group of fresh water lakes on Earth. They are sometimes called the inland seas. There are: 1. Lake Superior (the largest and deepest) 2. Lake Michigan (the only one entirely in USA) 3. Lake Huron 4. Lake Erie (smallest and most shallow) 5. Lake Ontario (much lower elevation than the rest). The Great Lakes between the USA and Canada are joined together by rivers and canals. The lakes are connected to the Atlantic Ocean by the St. Lawrence River and to the Hudson River by a canal. Between Lake Ontario and Lake Erie is Niagara Falls (51 m). Another large lake in the USA is Great Salt Lake. It is saltier than the sea. Rivers The Mississippi river is the major river of North America and the United States. It flows from

They include more than 500 species of eucalyptus, or gum trees. Only the big river red gum is seen nearly everywhere. These can be found beside rivers and dry riverbeds. Some gum trees are valuable timber species and have been cut down for many years. Gum tree leaves are full of oils, which evaporate easily. Another big family of native plants is the acacias. They are also known as wattles. There are about 900 wattle species. The golden wattle is Australia’s native flower. Its gold flowers and green leaves inspired the colours worn by many Australian sporting teams. In Australia bushfires are very often to happen. Because the trees and shrubs do not lose their leaves in winter, but grow throughout the year. But when the dry leaves and branches fall down, then there is a lot of dry material and that helps bushfires to burn. 5 Animals Scientists estimate that the continent is home to more than one
Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. The most distinctive characteristic of tundra soil is its permafrost, a permanently frozen layer of ground. The average winter temperature is -28°C, but the average summer temperature is 3-16°C. During the brief summers, the top section of the soil may thaw out allowing plants and microorganisms to grow and reproduce. However, these plants and microorganisms become dormant during the cold winter months. Soil is formed slowly. The constant freezing and thawing in the tundra helps to break the rocks into smaller pieces. Permafrost consists mostly of gravel and finer material. The arctic tundra is also a windy place and winds can blow between 48 to 97 kilometres. The tundra is basically like a desert when it comes to precipitation
In 2000 more than 80% of all new plantings were red, with shiraz, cabernet and merlot at the top of the list. At the same time, 87% of all vines uprooted were white, mostly chenin blanc, white French and colombard. There is a shift from chardonnay to sauvignon blanc, a varietal which lends itself to a larger range of styles and quality levels. All in all, in the year up to the end of 2000, 6 042.7 hectares of new vines were planted. In 2000 the total grape crop was about 1-million tons, from which 830-million litres of wine were made by 355 active cellars, of which 185 were non-estate "private producers", 92 registered "estates", 69 co-operatives and nine producing wholesalers South African cuisine For the more daring diner, South Africa offers culinary challenges from crocodile sirloins to fried caterpillars to sheep heads.

domestic livestock. As a result much of the world's savannas have undergone change as a result of grazing by sheep, goats and cattle, ranging from changes in pasture composition to woody weed encroachment. The removal of grass by grazing affects the woody plant component of woodland systems in two major ways. Grasses compete with woody plants for water in the topsoil and removal by grazing reduces this competitive effect, potentially boosting tree growth. In addition to this effect the removal of fuel reduces both the intensity and the frequency of fires which may control woody plant species. Grazing animals can have a more direct effect on woody plants by the browsing of palatable woody species. There is
European yew Ursula 11. kl Description It is a small- to medium-sized evergreen tree, growing 1020 metres. The bark is thin, brown, coming off in small flakes aligned with the stem. The leaves are lanceolate, flat, dark green and highly poisonous. The seed cones are highly modified, each cone containing a single seed long partly surrounded by a modified scale which develops into a soft, bright red berry-like structure called an aril. The arils are mature 69 months after pollination, and with the seed contained are eaten by thrushes, waxwings and other birds. The aril is not poisonous. The seeds themselves are extremely poisonous and bitter, but are opened and eaten by some bird species Toxicity The bark, stem, needles and seeds of the
Under surface pressure and temperature conditions, lighter hydrocarbons methane, ethane, propane and butane occur as gases, while pentane and heavier ones are in the form of liquids or solids. However, in an underground oil reservoir the proportions of gas, liquid, and solid depend on subsurface conditions and on the phase diagram of the petroleum mixture. An oil well produces predominantly crude oil, with some natural gas dissolved in it. Because the pressure is lower at the surface than underground, some of the gas will come out of solution and be recovered (or burned) as associated gas or solution gas. A gas well produces predominantly natural gas. However, because the underground temperature and pressure are higher than at the surface, the gas may contain heavier hydrocarbons such as pentane, hexane, and heptane in the gaseous state. At surface conditions these will condense out of the gas to form natural gas condensate, often shortened to condensate
of these can vary considerably. Some technologies are already mature and economically competitive (e.g. geothermal and hydropower), others need additional development to become competitive without subsidies. This can be helped by improvements to sub-components, such as electric generators. The table shows an overview of costs of various renewable energy technologies. For comparison with the prices in the table, electricity production from a conventional coal-fired plant costs about 4¢/kWh. Though in some G8 nations the cost can be significantly higher at 7.88p (~15¢/kWh).Achieving further cost reductions as indicated in the table below requires further technology development, market deployment, an increase in production capacities to mass production levels,and of the establishment of an emissions trading scheme and/or carbon tax which would attribute a cost to each unit of carbon emitted; thus reflecting the true cost of energy

The soil microflora largely depends on the type of soil, temperature, moisture, plant growth, nutrients, pH, and many other factors which may vary between locations but also within a single plot and over very small distances (OECD, 2007). Nevertheless of the quantity of microflora, biomass of all microorganisms living in soil play an important role in the functioning of entire soil ecosystems because their enormous biochemical activity (Barabasz et al. 2002). Soil microflora cycles carbon, nitrogen, phosphorus, and sulfur, plays a role in soil structure
The winter season can last from October to May. The summer season may last from June to September. The temperatures in the Alpine biome can also change from warm to freezing in one day. Alpine animals have to deal with two types of problems: the cold and too much high UV wavelengths. 4. How are plants adapted to life in the biome? Tundra plants are small -- usually less than a foot high .The hairs on the stems of many tundra plants, such as the Arctic crocus, help to trap heat near the plant and act as protection from the wind. Plants adapted to the tundra have small waxy leaves to prevent the loss of precious water in this dry environment. Quick-Developing, Cup-Shaped Flowers Soil Not Needed for Growth Polar Desert- Plants that grow in the Arctic regions must be very hardy and adapted to the extreme winter cold of these environments. Polar desert plants have a summertime growing season, but in the Arctic and Antarctic
In most of the countries where biogas is produced, the excreta of the cattle and other farm animals are used. In India gobar or cow dung is used for the purpose of making biogas. 20% of the excreta of animals are made up of dust particles that are inorganic in nature. The percentage of the inorganic dust particles is brought down by combining water with the excreta in a 1:1 ratio. The rate of feeding of any biogas manufacturing plant that is based on dung is 3,500 kilograms per day. Under normal circumstances the microbial content of the biogas is maintained by the addition of 2% of the expended slurry of the slurry of the fresh dung. 1% calcium ammonium nitrate of the dung is combined with the slurry in such cases. At times waste of kitchens and excrement of human bodies is used in these processes. The human excreta are supposed to occupy, at the most, 3% of the slurry.
1. What is a plant? Plant is a living organism. It is made up of different parts, each of whitch has specialized function. 2. Name the parts of a shoot system. The shoot system above the ground consists of the stem, the leaves, flowers and fruit. 3. What are the main functions of a shoot system? Main functions of a shoot system are: * Stem- to support the plant, to transport water, minerals and sugar * Leaves- to make food by photosynthesis, to absorb water from air * Flower- to contain reproductive organs, the reproductive function *Fruit- to enclode the seeds, to protect seeds 4. What are the main functions of a root system? Main functions of a root system are to take in, absorb water and minerals, to hold the plant firmly in the soil. 5. What happens in the process of photosynthesis?

Because sea passages were narrower between the Java and Borneo islands, the first Aborigines could reach Australia from the north. When they finally got to Australia, it was in a much better condition than nowadays. There were large animals, who are now extinct, that provided much meat. The Aborigines lived in harmony with the environment. Because they were cut off from the rest of the world, Aborigines could not trade goods, acquire animals or crop seed, which was very important because the land did not contain any cultivated crops. Aborigines lived in clans that all had occupied a piece of land. Nobody thought about selling, buying or trading land because the clan was a part of the land they owned. Finding food was not easy at that time. In some areas, both men and women had to spend over half 2 of each day on hunting or gathering food

The kitchen and bathroom look like an ER. If you think that's craziness, you're right. Fortunately, you don't need to be a guinea pig to benefit from one. Hundreds of men and women have tested the techniques in The 4-Hour Body (4HB) over the last two years, and I've tracked and graphed hundreds of their results (194 people in this book). Many have lost more than 20 pounds of fat in the rst month of experimentation, and for the vast majority, it's the first time they've ever been able to do so. Why do 4HB approaches work where others fail? Because the changes are either small or simple, and often both. There is zero room for misunderstanding, and visible results compel you to continue. If results are fast and misunderstanding, and visible results compel you to continue. If results are fast and measurable,2 self-discipline isn't needed. I can give you every popular diet in four lines. Ready? · Eat more greens. · Eat less saturated fat.
The wet forests give place to beautiful grasslands with some trees called the savannas. Farther west the trees disappear and the bushlands begin. The real desert occupies the centre of the Western Plateau. In the very southwest there are thin forests of evergreen trees. Most of Australian trees are kinds of eucalyptus (or gum tree to Australians) and acacia (wattle of Australians). Eucalyptuses give the people timber and eucalyptus oil. Of 600 kinds of acacias the golden wattle, the national flower of Australia, is the best known. Of other trees there grow bottle trees in the savannas, tree ferns in the tropical forests and many others. Lakes Australia has much underground water. There are only few lakes which are full of water only after it rains. The biggest lake is Lake Eyre which is a salt lake. The natural lakes of the interior of continental Australia are salt lakes. Fed by streams and rivers, they receive water rarely. Lake Eyre, Torrens, Frome and Gairdner are the remains of a

majority of the year. Climate sculpts the landscape through heat, cold, humidity, light and wind. In Canada, the variety of landscapes shows the diversity of our climate. In the north, low precipitation and cold temperatures favour permafrost and suppress vegetation growth, resulting in treeless tundra. South of the tundra, on the Canadian Shield, summers are short and warm, and winters are long and cold. Annual precipitation is abundant, allowing coniferous forests to establish and grow. On the Pacific coast, the combination of heavy rainfall and mild temperatures year round supports Canada, Kärt Kalvet 8a temperate rain forests. On the Prairies, the large number of days of sunshine affects the development of the agricultural landscape. In the Maritimes, the Atlantic Ocean moderates the climate such that winters are generally long and mild, and summers are short and cool. These conditions help in the development of forests. Finally, around the Great Lakes and alongside the
All utility-scale reactors heat water to produce steam, which is then converted into mechanical work for the purpose of generating electricity or propulsion. In 2007, 14% of the world's electricity came from nuclear power. More than 150 nuclear-powered naval vessels have been built, and a few radioisotope rockets have been produced. Nuclear life cycle The Nuclear Fuel Cycle begins when uranium is mined, enriched, and manufactured into nuclear fuel, which is delivered to a nuclear power plant. After usage in the power plant, the spent fuel is delivered to a reprocessing plant or to a final repository for geological disposition. In reprocessing 95% of spent fuel can be recycled to be returned to usage in a power plant. What is nuclear energy? Nuclear energy was first discovered by French physicist Henri Becquerel in 1896, when he found that photographic plates stored in the dark near uranium were blackened like X-ray plates, which

middle latitudes typically have between 25 cm and 50 cm of precipitation a year. Much of this falls as snow, serving as reservoir of moisture for the beginning of the growing season. Warm to hot summers are experienced, depending on latitude. In the winter, grassland temperatures can be as low as -40° C, and in the summer it can be as high 20° C. There are two real seasons: a growing season and a dormant season. The growing season is when there is no frost and plants can grow (which lasts from 100 to 175 days). During the dormant (not growing) season nothing can grow because it's too cold. Taiga- Long, cold winters, and short, mild, wet summers are typical of this region. In the winter, chilly winds from the arctic cause bitterly cold weather in the taiga. The length of day also varies with the seasons in the taiga. Winter days are short, while summer days are long. The average temperature is below freezing for six months out of the year
Forests Tropical and subtropical forests, also known as rainforests or tropical rainforests, are lavish and ample forests with broad leave tree. They are mostly found at lowlands near the equator - Asia, Africa, South & Central America and on many of the Pacific Islands. Almost 50% forests of the world are tropical and subtropical in nature. Rainforests are characterized by high rainfall. They are home to two-thirds of all the living animal and plant species on the planet. Tall, broad-leaved evergreen trees are the dominant plants, forming a leafy canopy over the forest floor. The undergrowth or understory in a rainforest generally consists of shade-tolerant shrubs, herbs, ferns, small trees and large woody vines. The temperature ranges from 5°C to 50°C. Human uses of tropical and subtropical forests:
