...Biology I Silent Spring Book Review The four chapters of Silent Spring that I am reviewing are the first four of the book. I decided to do the first four because after reading this book, I thought that those chapters had the biggest impact of my views in the world’s pesticide problem. The first chapter of Silent Spring is a very powerful, fictional, yet possible fable of what can happen to the Earth, because of pesticide use. This chapter starts with describing a beautiful town in America. It describes the farms, the trees, and the wildlife that all live in harmony. Then the chapter begins to describe the plague that this town experiences. All of the wildlife and plants begin to die, and all the people in the town begin to get very ill. Eventually the town becomes silent and everything has withered and died. The most powerful part of this chapter is the fact that it could be true. The second chapter of this book describes the history of life. It talks about how living things affect its surroundings. I have always been taught that with every action there is a reaction. In this chapter, people use pesticides to get rid of the insects that are harming their crops. As they put it, the pesticides should really be called biocides, because they affect more than just the insects. The pesticides get into everything, including humans. Without knowing it we all become affected by the pesticides. The sad part is, is that even though pesticides are harmful to us and our...

...Tardigrades can be found everywhere on Earth these days. Scientist have found that these animals are in places like the Sahara Dessert and Antarctica. These organisms are able to survive almost everywhere. They have the ability to survive in the harshest environment. They can survive without oxygen for 10 years. In 1920, a scientist tested the organism through an experiment. The scientist put the Tardigrade in boiling hot water with temperature up to three hundred degrees, this gave an amazing result when the tardigrade survived through this peak temperature. The tardigrades have survived all the massive extinctions that have been on Earth. These animals live in the moss. This moss is soft and has to be moist. Many scientists say that the tardigrade...

...to people everywhere. They affect a lot of people worldwide. Floods can also be caused by a number of events. Snow melts, tropical storms, and dam or levee breaks are just a few of the causes of floods. Floods often cause damage to homes and businesses if they are in the natural flood plains of rivers. While river flood damage can be eliminated by moving away from rivers and other bodies of water, people have traditionally lived and worked by rivers because the land is usually flat and fertile and because rivers provide easy travel and access to commerce and industry. Although you can lessen the chance of floods occurring in your area by moving, floods can still occur everywhere and affect everyone. National Hazards: Floods Floods are one of the most dangerous natural disasters on Earth. Floods have cost humanity millions of dollars in damages and so much more. They are also very fatal. Every year, floods kill 6,753 people. While this may seem like a low number of deaths compared to car crashes or earthquakes but when other affects of floods are seen, Floods are seen as very dangerous disasters. They effect people from every part of the globe, effecting over 96,878,672 people and are caused by many things. In floods that result from snow melts, people in areas that are not close to large bodies of water are still susceptible to snow. Snow melts start when an area experiences heavy snowfall. After the snow starts to melt but the ground remains frozen, the water begins to...

...almost vomited everywhere by me. It was a scary thought that I was alone on this creepy island for all I knew there could have been a tiger near by. And be very hungry then attack me thinking I’m food. That scares me even more thinking about it so I should just try to think of something else like a horse or a cow. That scared me more though because a tiger would eat a horse or a cow. So it just happened and I vomited everywhere. Just thinking about food reminded me that I should just grab my bookbag and look for food in it. If not grab my knife out of the bag and some rope tie it to a stick and go hunt for some food....

...The bacterium is transmitted through excrement of faeces and if this comes into contact with drinking water, the bacteria can infect people. Bacteria can also spread to food, if people don't wash their hands thoroughly after using the toilet meaning it can be spread from person to person. The symptoms of cholera include; extreme diarrhoea (as much as a litre an hour), vomiting for hours on end, and may also lead to dehydration and electrolyte imbalance which could then cause death. This is because the cholera bacterium produces a toxin, which affects chloride ion exchange. The toxin causes the chloride ion protein channels in the plasma membranes of the small intestine epithelial cells to open; the chloride ions then move into the lumen of the small intestine, this build up of chloride ions lower the water potential in the lumen. Consequently water moves out of the blood, across the epithelial cells and into the lumen by osmosis, the increase of water secretion in the lumen results in a high amount of water being lost from the body, which is what causes the symptoms. Ways to prevent cholera spreading would be; proper sewage systems, treating water, hygiene such as washing hands after using toilet and preparing food, also covering food which may come into contact the bacterium. The quickest way to replace fluids in the body would be through a drip however not everywhere has access to drips, so cholera can be treated by methods such as oral rehydration therapy. Which involves...

...ago in ancient world, the world began with Fire, Water, and Air. Together they created the world and everything in it. These three kingdoms: Fire kingdom, Water kingdom, and Air kingdom are the three powerful kingdoms of the ancient world. Each kingdom has its own underworld itself. Within the three kingdoms, Fire kingdom was the most powerful of all. This kingdom was so powerful that it will destroy everything in it pass. They are ferocious kingdom that destroyed whose ever against them. On the other hand, Air kingdom was a calm and compassion kingdom. They are the kingdom of inspiration, imagination of dream and wishes. They symbolize love and motherhood. This kingdom was ruled by the god and the goddess of air. They even have a child called Wind. Wind will eventually be the god of air who will one day take his kingdom to dominate the world. As Air kingdom settle down into the night, there they saw the sky was glowing with brightest orange color of firing arrows coming down at them. Within in minutes, the land was light up with fire burning everything and turn into ashes. The Fire kingdom quickly defeated the Air kingdom and they prove to themselves that nothing can stop the power of fire. As the Air kingdom turned into molten of hot fluid like lava coming out of volcano, Wind was wondering into the forest where he normally does every night. As he approached his kingdom, all he can see was fire everywhere. He quickly ran back into the forest and began his...

...Bubbles, Bubbles Everywhere! By: Kamari Casiano My science fair project is about “Which dishwashing liquid will make the most bubbles? ”. I chose this topic because I like bubbles and sometimes use dishwashing liquid to blow bubbles. The materials of my project are 3 empty water 16.9 fl oz. water bottles, 1 measuring cup in ounces, 1 measuring cup in ML or teaspoons, 1 ruler, and 1 bottle of Dawn, Gain, and Palmolive dishwashing liquid. While conducting my experiment, the factors that will be changed are the types of dishwashing liquid. These dishwashing liquids are Dawn, Gain, and Palmolive. The factors that will not be changed are the amount of water; the amount of dishwashing liquid and the time spent shaking the bottles. My hypothesis is that Dawn will make the most bubbles. I think Dawn will make the most bubbles because it costs the most. If it cost more than the ingredients must be more powerful to make the most bubbles. I researched what causes the soap to make bubbles. According to www.thenakedscientists.com, the amount of bubbles that you see in dishwashing liquid is affected by two types of compounds: the hydrophilic compounds, that are attracted to and dissolve in water and the lipophilic compounds, that dissolve in fats oils and lipids. These compounds interact and group together. In detergent, they are central to the forming of the gas-filled bubbles of soap that we use to clean dishes. The number of molecules formed, and the level of surface friction...

...Mineral and Water Essay Sci 241- Ellsworth July 1, 2012 Water is virtually the most important thing we put into our body yet most of us don’t meet the daily requirements of water. Water keeps us hydrated healthy and alive, so why is it that so many people despise water. Water is full of minerals which depending on the minerals have different functions and sources. In addition to keeping us healthy and alive water plays several very important functions in our body, including regulating body temperature, aiding in food digestion, and flushing out sodium. It’s important to understand the effects of water on your body that way you can understand the signs, symptoms, and general effect that dehydration water has on the body. Every summer countless people end up in the hospital with signs of dehydration, most of those hospital visits could have been avoided with proper understanding of minerals and water. Minerals are important to the health and maintenance of our bodies and bodily functions. There are several different types and kinds of minerals each of these playing important roles in our body, there are trace elements and macro and micro minerals. For starters the macro minerals are calcium, iron, magnesium, phosphorous, potassium, and sodium. Each of these macro minerals have important functions in the body ranging from helping aid in the transfer of oxygen between tissues in the body to helping bones and teeth form, as well as controlling the...

...downward spiral. There are already thousands of drilling rigs, numbering 5,200 in an area crossing five states. The government wants to expand this number to about 10,000. What are the ethical issues of such a project? Encroaching industrial civilization poses a migratory issue for the wildlife. Roads will be built that the animals have to cross, fences made of barbed wire are springing up everywhere, drilling run-off is polluting the rivers, streams, and lakes that harbor a big trout population. The barbed wire fences alone causes much grief for the animals. The wildlife has to choose to jump over the or crawl under the fence. Either way can cause great bodily harm to the animal and in some cases death, if the animal gets snagged on the barbed wire. Aside from the obvious physical obstacles the animals must overcome, are the ecosystem obstacles, water pollution and depleted land. The run-off from the drilling rigs will find its way into the rivers, lakes, and streams, which are home to many species of aquatic life, including Trout. These water formations are also a source of drinking water for the many species...

...] Floods in Bangladesh can be divided into three categories: (a) monsoon flood - seasonal, increases slowly and decreases slowly, inundates vast areas and causes huge losses to life and property; (b) flash flood - water increases and decreases suddenly, generally happens in the valleys of the hilly areas; and (c) tidal flood - short duration, height is generally 3m to 6m, blocks inland flood drainage.The combined annual flood wave from the Ganges, brahmaputra and Meghna rivers passes through a single outlet, the lower meghna tide levels in the bay of bengal, reducing the slope and discharge capacity of the Lower Meghna. The effects of these high river water levels extend over most of the country and are the main determinant of the drainage condition and capacity. The discharge from minor rivers is reduced and surface drainage by gravity is limited to land above the prevailing flood level. Flooding caused by this drainage congestion exists nearly everywhere except in the highland and hilly areas in the northern and eastern parts of the country. | | | | | | | | The factors for causing floods in Bangladesh are: (a) general low topography of the country with major rivers draining through Bangladesh including a congested river network system, (b) rainfall in the upstream country or in the mainland, (c) snow-melt in the himalayas and glacial displacement (natural), (d) river siltation/lateral river contraction/landslides, (e) synchronisation of major river peaks and influences...

...Air and Water Pollution Jennilee Stieber ENV/100 February 24th, 2014 Jennifer Lake Air and Water Pollution Air and water are a necessity for all living things. There are naturally occurring and man based pollutants that effect the air that we breathe and the water we drink. Pollution is changing the world we live in, and understanding our pollutants helps us come to a better solutions and a future for our environment. Carbon oxides are air pollutants that are the gasses carbon monoxide and carbon dioxide. Both are colorless, odorless, tasteless, and are considered primary pollutants (Berg & Hager, 2009). Primary pollutants are emitted into the air directly by the sources. Carbon monoxide’s main source is vehicle exhaust, and other sources include from incomplete combustion. Carbon dioxide is released naturally through volcano eruptions and respiration. Some human activities that contribute to the production of carbon dioxide are deforestation and the burning of fossil fuels, such as oil and coal ("Global Climate Change", 2014). Carbon dioxide contributes to global warming by trapping in the heat from the sun in the troposphere and stratosphere, which leads to the whole Earth warming up. Carbon monoxide spreads in the troposphere, prevents other polluting gases to be release from the atmosphere and contributes to smog (2014). Particle matter is an air pollutant that consists of dust particles, lead, and sulfuric acid. There are solid and liquid particles...

...available everywhere. These are the two things that we have plenty of them. technology for electricity has evolved over time, but the basic principles of positive and negative charges can be demonstrated by creating a simple battery with supplies around the house and from a small electronics or home improvement store. Also known as an air battery, a saltwater battery uses the positive and negative ions from salt in water to generate a small amount of energy, enough to power a small, low voltage light bulb. Metal electrodes can be fashioned from metal nails that are long enough to extend past the water line of the solution. B. Statement of the Problem II. Why does salt conduct electricity in Water? C. Significance of the Study III. Unfortunately, When we do this investigatory project, it can helps the society, they can do it by their self, you can do by your own, or by your groups in society. Our investigatory project is little bit harder and easy, but we can sure that we can help other people, if we can do this experiment. D. Scope and Delimitation of the Study IV. Unfortunately, the cost of the technology to convert the saltwater will cost far the government huge allocations. Though this is said to be extremely economical, it has not yet been approved as practical to be used in everyday life. Another downside to this is that this technology, if ever developed, will only benefit the countries that have long coastlines or big bodies of water available...

...The afternoon sun shone with intensity on our bare backs making them warm. The warm, dry, gritty sand of Coney Island felt soft under by bare feet. People were scattered everywhere near the beach shore with colorful umbrellas. Even at this distance, we could hear indistinct chattering between people. Every one of us except the parents rushed to the ocean where the coldness of the water left me shivering. The foamy water that were the remnants of the crashing waves came up at regular intervals. The others continued to play in the icy ocean while I looked for the bucket that we brought with us to build a sand castle. I dumped buckets of wet sand onto the dry portion of the beach and called it a castle. Finished with the initial task, I started to dig deep trenches within the sand and that...
