Lady's slipper Common names: American Valerian, Moccasin Flower, Nerveroot, Whippoorwill's-shoe and Yellow Indian Shoe. Bionominal name- Cypripedium pubescens. The plant comes into flowering age only after 10-15 years. Height is 12-30 inches tall. Are found across much of North America, as well as in parts of Europe. This plant grows in the wild in forest lands and meadows, but owing to excessive harvesting, lady's slipper is seldom found growing in the wild. However, to a certain extent, this herb is also cultivated. This plant has only 2 leaves. The color of lady's slipper flowers varies from yellowish to purplish- brown and are borne at the top of an elongated stalk. One petal of the flower changes into a structure akin to a yellow sac, known as the `slipper'. The herb has a plump rootstock that gives rise to numerous curved stems covered with bristles. The stems bear alternate leaves and typical golde...

What is deep sea? Deep sea is nothing but the stumpy level in the marine that is found in the depth of more than 1800 m. This area is completely dark because no light can make a way inside it. 71 % portion of the earth is occupied by water and people are utilizing ocean for various purposes such as transportation, fishing, exploration and many more. However, the deep part of the sea is still remains untouched. Seeing the situation majority of the scientist thought that life would be scant in the deep sea, but almost each search has discovered that life is plentiful in this reason. The deepest layer of ocean has lots of unthinkable stories, secrecy and legends that make mankind more curious about the life that is surviving bottom of the sea. Deep sea animals Deep sea animals live in the marine ecosystem or in oceans. If you look at the marine biology, you will find millions of species of sea animals. The marine life is a large resource t...

How can we reduce air pollution level in cities? The air pollution levels are extremely high in cities, but how can people change this situation? Cars and big factories emit lots of deleterious gases into the air, for example carbonic acid gas, cities are not healthy places to live anymore. Firstly, we should using the public transport. Everybody can walk and bicycle instead of driving cars. Vehicles emit a lot of harmful gases into the air. Every family member does not need his or her own car. One car for the whole family would minimise the number of cars in cities and air pollution levels will come down. Secondly, people have to recycle. It would help reduce factories work. It will emit less harmful gases into the air. Finally, we should plant more trees in cities and also create more national parks. They produce oxygen. In conclusion, there are many ways to make cities better...

The country of my dreams The counrty of my dreams is Australia. It lies in the Southern Hempishere between the Pacific Ocean and Indian Ocean. One of the resones why i like Australia is its nature. It is recognized as a megadiverse counrty. Its isolation from other continets explains much of the strangeness of its animal and plant life. There are a lot of interesting animals like kangaroos, koalas and wombats and birds like emus and kookaburras. Australia is a highly developed country. It has the sixth largest per capita income in the world. It is said that Melbourne is the world's most liveable cities. Another reason why Australia appeals fo me, is its beautiful beaches and climate. Winters are mils and summers are hot and sunny. Australia's beaches are always full of surfers, and one day i hope i will be one of them . Australians have a very good quality of life. There are a lot of universities, where to ...

Newfoundland Geography Newfoundland and Labrador is located on the eastern edge of North America. Newfoundland and Labrador is home to Iceberg Alley, one of the best places in the world to view icebergs. Just off the coast, the meeting of the cool Labrador Current and the warm Gulf Stream creates an abundance of marine life that attracts thousands of whales, and provides rich nesting grounds for millions of seabirds. To put things in perspective, Newfoundland and Labrador is a little smaller than California, slightly bigger than Japan, and twice the size of the entire United Kingdom. Geography The island of Newfoundland covers 111,390 square kilometres. With the addition of the vast territory of Labrador, the province covers a total area of 405,212 square kilometres, and has more than 29,000 kilometres of unspoiled coastline.

Retelling the Aboriginal people 1. The formation of the continent Australia, a continent of geographic and biological diversity (mitmekesisus), has an amazing range of animal and plant life, as well as one of the world's oldest ethnic groups. After the last Ice age, when sea rose considerably (märkimisväärselt kasvanud), Australia and its largest island Tasmania, became isolated form the rest of Asia. 2. The earliest inhabitants The earliest humans living in Australia are called Aborigines and they are descended (pärinevad) from among the earliest humans in the world. For thousands of years Aborigines lived as hunter-gatherers along the coast and in the inland desert areas, following the same lifestyle as their ancestors. 3. Finding food and water Aboriginal tribes obtained water from trees and roots and even squeezed water out of the bodies of frogs. Women collected anything that grew or moved,...
How can we increase the quality of breathable air? “I’ll go out for a breath of fresh air” is an often-heard phrase. But how many of us realize that this has become irrelevant in today’s world? Air pollution is the addition of any harmful substances to the atmosphere, which causes the damaging of the environment, human health and the quality of life. Firstly, we should use green methods of powering like wind energy and landfill gas energy. This would reduce the amount of harmful gases. Another useful suggestion would be to plant trees. In this way we can increase the source of breathable oxygen. Unfortunately, many companies are contributing to deforestation. Finally, it would help if we put taxes on carbon emissions or higher taxes on gasoline. In this way people and companies will have greater incentives to conserve energy and pollute less. In conclusion, there are many ways to ...

Environmental problems Nimi Klass Biodiversity The variety of life on Earth, its biological diversity, is commonly referred to as biodiversity. The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach. In some way or form, almost all cultures have recognized the importance of nature and its biological diversity for their societies and have therefore understood the need to maintain it. Yet, power, greed and politics have affected the precarious balance. Why Is Biodiversity Important? Who Cares? · Why is Biodiversity important? Does it really matter if there aren't so...
Good morning! My name is Marianne Kümnik. I will be speaking today about strawberries. My presentation will last for about 10 minutes. Please can you save your questions till the end. Choosing Cultivars Some cultivars perform better than others, but it is difficult to predict which will grow best in a particular garden. Perhaps the best way to decide which cultivars to grow is to find out what works well for neighbours or local commercial growers. Before planting strawberries in a large area it’s good to try several promising cultivars Some cultivars that perform well: • Earliglow—perhaps the best-flavored cultivar, it is among the earliest to ripen. • Northeaster—ripens about the same time as Earliglow. It is resistant to red stele and does well on heavier clay soils. The berries are large and have a hint of grape flavor, which some people love and others dislike. • Sable—has excellent flavor and also ripens early. • Allstar—a relia...

I'd like to present the main issues of our planet and today i'll name 5 of them. These are air pollution, water pollution, endangered animals, deforestation and rubbish. Air pollution Firstly, lets talk about air pollution, which endangeres our life in cities and also the forests near by. Cars and factories blow poisoned gas in the air and it mixes with the oxygen, so the air that we breathe, becomes dangerous to our health. The ozone layer around the Earth, there is a special type of oxygen called ,,ozone". Ozone is important because it stops ultraviolett radiation from the sun. Many aerosol sprays and factories destroy ozone and they have made a very big hole in the ozone layer. This means that too much ultraviolet radiation now enters the Earth. This is very dangerous because it can cause cancer. Poisonous chemicals ...

Estonian University of Life Sciences Report on Soil Microflora By Katrin Vares Tartu 2013 Introduction The purpose of this report is to define soil microflora and establish the importance of it. Since the microorganisms clearly play an important role in preserving the balance of life, the next objective is to look into factors that influence this balance. Natural conditions and cultural impact could be considered as the variables that correlate the most with the activity and composition of microflora, hence some of the natural and cultural factors will be looked into a little more in detail. Definition, composition and importance of microflora Saunders Comprehensive Veterinary Dictionary (2007) cited by the online medical dictionary (2013) defines living microorganisms as that small that they can be seen only with a microscope and that maintain a more or less constant presenc...

Acid rain is rain or any other form of precipitation that is unusually acidic. It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the production of sulfuric oxides into the Earth's atmosphere with positive results Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased.[2][3] In 1852, Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England.[4] Though acidic rain was discovered in 1852, it was not until the late 1960s that scientists began widely observing and studying the phenomenon.

Estonia is a small country in Northern Europe with an area of about 45 000 sq km. The country's climate is determined by the proximity of the Atlantic Ocean. The summer temperatures are a little lower than the average of that latitude, but the winters are considerably warmer. As a part of the East-European Plain, the country has a rather flat surface. The highest and most topographically variagated region in Estonia is in the south-eastern part of the country. The Sakala Upland plains offer contrast to the hills of Ottepää, Karula and Haanja. At 318 metres, Suur Munamägi ('Great Egg Hill') is not only the highest point in Estonia, but of all the Baltic countries. The country has 3974 km of coastline, while the land border, in comparison, is only a mere 633 km. The coast varies from limestone cliff in the north to sandy beaches in the west. Most of Estonia's many islands belong to the West Estonian archipelago. The largest islands are Sa...
The sunflower (Helianthus annuus) is an annual(iga aastane) plant in the family Asteraceae, with a large flower head (inflorescence(õiekobar, õisik, õitseaeg, õidumine)). The stem(tüvi) of the flower can grow up to 3 metres tall, with the flower head reaching 30 cm in diameter. The term "sunflower" is also used to refer(nimetama, viitama, üle andma) to all plants of the genus(perekond, sugu) Helianthus, many of which are perennial(alaline, aastaringne) plants. What is usually called the flower is actually a head (formally(ametlikult) composite(liit-, komposiit- ; korvõieline, komposiit) flower) of numerous flowers (florets) crowded(täistuubitud, tunglev, rahvarohke) together. The outer flowers are the ray florets(pähik (õisiku osa) and can be yellow, maroon, orange, or other colors, and are sterile(steriilne, viljatu). The florets inside the circular head are called disc florets. Sunflower head displaying florets in spirals of 34 a...
Kordamisküsimused 1.prax: · Mis on rakuliin ja rakkude primaarkultuur, mille poolest erinevad? Primaarne rakukultuur on otseselt koest eraldatud rakkudest koosnev ja piiratud jagunemisvõimega kloon. Rakuliin on imortaliseeritud kloon, mis on võimeline paljunema/ jagunema piiramatult. Immortaliseeritud liine saab kas iseeneslike mutatsiooni tagajärjeliste transformatsioonide kaudu, ka eraldades rakke kasvajatest. Tekitada kunstlikult telomeraasi sisseviimisel rakku. Rakuliin sageli aneupolidne- kromosoomide arv normaalsest erinev (tavaliselt suurem). Eri rakutüübid transformeeruvad eri sagedusega, suured liikidevahelised erinevused. · Milleks on söötmesse lisatud seerum, antibiootikumid ja aminohapped? Et rakud end hästi tunneksid. Seerum-keskkond + mitogeenid=kasvufaktorid ja muud proliferisatsiooniks vajalikud substansid. Antibiootikumid-et bakterid vohama ei hakkaks, meie rakud olid antibioo...
LONG BEFORE the white man set foot on American soil, the American Indians, or rather the Native Americans, had been living in America. When the Europeans came here, there were probably about 10 million Indians populating America north of present-day Mexico. And they had been living in America for quite some time. It is believed that the first Native Americans arrived during the last ice-age, approximately 20,000 - 30,000 years ago through a land-bridge across the Bering Sound, from northeastern Siberia into Alaska. The oldest documented Indian cultures in North America are Sandia (15000 BC), Clovis (12000 BC) and Folsom (8000 BC) Although it is believed that the Indians originated in Asia, few if any of them came from India. The name "Indian" was first applied to them by Christopher Columbus, who believed that the mainland and islands of America were part of the Indies, in Asia. So, when the Europeans started to arrive in the 16th- an...
ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released ...

It is only knowledge produced with difficulty that we truly value. To what extent do you agree with this statement? Session: May 2017 Word count: 1212 It is only knowledge produced with difficulty that we truly value. To what extent do you agree with this statement? To be knowledgeable is to have an understanding about how things are and how things work. Knowledge is the combination of facts, information, and/or skills that when put together create a whole picture enabling us to fully understand a subject or situation. We, as ordinary people, can acquire knowledge either from our first hand experiences (personal knowledge) or from education and research (shared knowledge). Difficulty depends on how much effort or skill must be implemented for the information to be acquired, and the value of something lies in it's importa...
