... What are the factors that make dental hygiene important. (The invention of the tooth brush and diseases.) Your teeth are one of the many beauties of the human body; they come in all shapes, sizes, and even curves. Now you may ask what effects teeth have on humans besides beauty, well, there are many. They are what is essential for us to survive and to obtain nutrients, in order for our bodies to function daily, so it is very necessary that we care for them in the most special way, first lets take you into how the care for teeth got to where it is today. Before there was the invention of the toothbrush, people used rough cloth and chalk to rub across their teeth and even sometimes with the addition of products like salt and powder. The ancient Chinese would chew on twigs with a special flavor to freshen their breath. The ancient Greeks and Romans used crushed bones and oyster shells to clean their teeth with. But then, along came the invention of the tooth brush by the ancient Chinese, they cut open pigs and used the pieces of their neck to assemble what they called bristles to begin cleaning their beauties. Many years after, a man named William Addis was thrown into jail for starting a riot, since he wanted to stay fresh, he used his time to think of ways to stay on top of things, what he did was carve a bone handle, drill holes into it, and inserted boar bristles, that were held in place by wires. His contraption was very well known and he become very wealthy by the time...

...Bre Patrick Period: 7 Honors Anatomy December 4, 2014 1. What is the purpose of skin? What functions does it serve? How does it serve these functions? The purpose of skin is to protect the organs inside the body. The functions of skin is protection, excretion, maintence, synthesis, storage, and detection. Protection underlying tissues and organs against shocks, absorption and chemical attack. Excretion of salts, water and organic wastes by integumentary glands. Maintence of normal body temperature through either insulation or evaporative cooling, as needed. Synthesis of Vitamin D3, a steroid that is subsequently converted to the hormone calcitriol, important to normal calcium metabolism. Storage of nutrients. Lipids are stored in adipocytes in the dermis and in adipose tissue in the subcutaneous layer. Detection of touch, pressure, pain, and temperature stimuli and the relay of that information to the nervous system. 2. What are five layers of the skin? Describe each. There are actually three layers to the skin; The Epidermis, The Dermis, and the Subcutaneous Fat Layer. However there are five skin layers that take place in the epidermis. * The Epidermis: provides mechanical protection and helps keep microorganisms outside the body. * Stratum Spinosum: the outermost epidermis layer that protects against foreign materials and to produce and retain moisture, which it does through a series of cellular-level interactions and interchanges. *...

...absence of food. While the idea of missing even one meal might put most of us in misery, fasting does have many benefits for the body. 4. Fasting has been called the "miracle cure" because the list of physical conditions improved by fasting is long and varied. Cited most often are allergies, arthritis, digestive disorders of all kinds, skin conditions, cardiovascular disease, and asthma. Because fasting initiates the body's own healing mechanisms, any ailment may show improvement. 5. Fasting frees up energy so healing can begin.Fasting is a wonderful antidote for our usual over-indulgences. There's nothing wrong with enjoying our food, but excess food on a continuous basis does create a burden for the body. When it must handle more than is comfortable and appropriate for it, it will suffer. 6. Imagine at work how you feel when you're handed a huge work load--more than you can handle in your 8-10 hour day, more than is comfortable and appropriate for your job title (or salary level). You're under duress. But you will cope. You must cope. You must make decisions. You attend to the most important and urgent of matters and set aside those that can wait for another day. 7. During fasting, we rest our system from the constant onslaught of food stuffs. We usually think of food as giving us energy, so it can be a new way of thinking to understand how the food we eat actually requires energy. Digesting, assimilating and metabolizing,these activities require a great deal of energy...

...other liquid. However the ability to be soluble depends on a substances polarity and bonding. This then contributes to the various ways that different types of chemicals interact in water. Solubility is crucial to every living thing on earth as water can carry along valuable chemicals, minerals, and nutrients necessary for survival. In fact Water covers 70% of the Earths surface and composes 55-70% of the human body. Water is an excellent solvent due to its chemical composition and physical attributes. According to USGS (http://water.usgs.gov/edu/qa-solvent.html ) Water molecules have a polar arrangement of the oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) has a negative charge. A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. This causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative. "Like dissolves like" is an expression used by chemists to help them remember how solvents work. The expression refers to "polar" and "nonpolar" solvents and solutes. For example water is polar and Oil is non polar thus water will not dissolve oil. Therefore nonpolar molecules don't dissolve very well in water, including many organic compounds, such as fats and waxes. Water molecules can become attracted to several other types of molecules due to its polar bonds. Water can become so heavily...

...Earth’s 6 ¾ billion people for agriculture, industry, recreation, tourism and municipal use. This remaining useable freshwater is in the form of lakes, ponds, rivers, streams, and general wet areas. Lakes, ponds and bogs are generally stationary bodies of water, although bogs can be a source of rivers and streams, which are moving bodies of water. Freshwater ecosystems support us many other ways too; dams can be built to harness the power of rivers to generate electricity. Rivers also provide water for irrigation and industry, processing wastes, producing timber and supplying food. Freshwater serves an important role in transporting goods via ships. They also serve for recreational, cultural and aesthetic purposes. Because of the huge demand we have on freshwater systems, they require 'Management and Policies' in order to regulate and protect them. Pollution and waste due to industrial exploitation and overpopulation are a serious threat to our freshwater resources. Residential, commercial and industrial premises are often concentrated near waterways, lakes and rivers. Historically, humans have congregated by freshwater and used it as medium for transport of goods and people. Now that we know how important water is to the planet and humans we as a country need to step up and reserve and save our fresh water resources. My plan of action is to make up some pamphlets and bring them to my local community center and my mayor’s office. I am going to try to sit down and talk to my mayor...

...OCEANIC IMPACTS Plastic Waste Humans have been utilizing the ocean for millions of years and have created serious problems within our oceans. Plastic pollution has caused huge problems in our oceans, as massive amounts of plastic trash ends up in our oceans every year. According to recent studies at least 5 trillion pieces of plastic waste are now floating in the world’s oceans. This waste for the most part sinks to ocean floor, what remains at the surface has created large whirlpools, and a significant amount of it washes onto our coastlines daily. (Parley, n.d.) The Pollution Problem Plastic pollution within our oceans is caused by following reasons: debris washed into the ocean from rivers after heavy rain or floods, blown off of garbage...

...brief overview of the Western gray squirrel (Sciurus griseus) and I’ll describing the environment that the squirrel lives in, as well as explaining the major role the squirrel plays in its environment. I will also be discussing the main functions and structures of the western gray squirrel’s main organs and how the western gray squirrel has evolved physiologically to become suited to the environment around it. The last thing I will be examining is the changes if any that the western gray squirrel would have to face environmentally as well as biologically if transplanted to a significantly different environment. One of three subspecies of native tree squirrels is the western gray squirrel. The western gray squirrel relies on the diverse old growth canopies of pine tree, oak tree, and fir tree forests, for natal dens, food, travel, and protection. The western gray squirrel will usually select larger patches of forested habitat usually away from human habitations. With an average body length of twelve inches and tail length of an additional twelve, the western gray is the largest of the native tree squirrels. This arboreal rodent has white-tipped gray hairs along much of its body and a white underbelly. It is noted for its large feet, pronounced reddish brown ears, and long bushy tail. Western gray squirrels do not hibernate, but will remain confined to their nests during periods of bad weather. Western grey squirrel's main source of food depends largely upon local habitat characteristics...

Besides, high employee turnover can harm McDonald’s ability to retain customer and provide high-quality customer service. Customers might feel more convenient and comfortable talking to the same employees and customer service representative over time. Negative Publicity Negative publicity is the adverse publicity that McDonald’s face due to particular reason, which may lead to potentially disastrous consequences. Documentaries such as 2004’s documentary “Super Size Me”, documented Morgan Spurlock’s rapidly deteriorating health as he ate only McDonald’s for a 30-day period, every item on the chain’s menu at least once. Morgan Spurlock gained 11.1 kilograms, a 13% body mass increase and experienced mood swings, sexual dysfunction, and fat accumulation in his liver. As a result, many health conscious consumers do not even consider having a meal at McDonald’s. Negative publicity has tarnished the reputation of McDonald’s among its customers. Needless to say, it...

...BUILDING MASS There are 4 Key Components in gaining lean body mass: They are: 1.Eat Lots of Good, Clean Food. 2. Work-Out Hard. 3. Supplement Properly. 4. Sleep Long. Notice that I put "eating lots of good, clean food" at the top of the list. Let's face it, more Calories = more mass, period. To build muscle, it is imperative to have adequate calories to build with. This doesn't mean to rush to Burger King and order 10 Whoppers. LOL, you want good, clean calories, like those found in your basic, down-to-the-earth-type foods such as: Potatoes, Rice, Oatmeal, Beans, and Yams. Meals should not include much the following: dairy products, sugars, or fats. You need to try to break your daily caloric, protein, carbohydrate, and fat intake into 6 even meals. Meals should be spaced out by between 2-3 hours. It is important to check your bodyfat once a week. You should eat enough to gain about 1-2 pounds of muscle per week Work-Out Hard Intensity is the Ingredient that makes Muscle Soup. Training Hard Doesn't mean getting pissed and curl 150lbs with your body. It means to put a weight that you can honestly pump out some good, clean reps with strict form. Get your spotter to help you with a few extra reps. If you can get used to the "Pain of the Growth Zone", have your spotter spot you until he/she gets tired. The Intensity of this type of training is Awesome! You may also consider getting a personal trainer. When you look for a personal trainer, you should look for someone who:...
