...Earth Life refers to any living system that can maintain homeostasis, grow or have the capacity to do so, respond to environmental stimuli, reproduce in some manner, and adapt to environmental changes. Anything that can do these things is referred to as a living organism. Life on Earth consists of carbon forms. Carbon is a key component for all life that has naturally occurred on Earth. Molecules made of carbon bond with hydrogen, nitrogen, and mostly oxygen to make complex molecules. The substance carbon is in excess on Earth. It is easy for enzymes to move and manipulate carbon molecules due the size and the fact that they are lightweight. The most common elements found in living organisms on Earth are hydrogen, nitrogen, oxygen, phosphorous, sulfur, and carbon. Possibilities of Extraterrestrial Life in Our Solar System The possibility of life within our solar system has been a question asked for years. Space exploration in the 1960s started to answer the question with no. Probes sent out to search for life have not returned any signs of it. Human life can be ruled out within our solar system due to the conditions on the planets and moons within the solar system being uninhabitable by humans....

...Module 3 Waves and the Electromagnetic Spectrum Topic: Waves 1. What is a wave? A wave is vibration that travels and all waves are created by something vibrating. Waves transport energy but do not transport mass. 2. Describe the following terms associated with waves: a. amplitude height of wave b. wavelength length of a wave c. frequency number of waves per second (Hz) d. period how long a wave lasts when it arrives at a fixed point (measured in seconds) 3. What are radio waves? An electromagnetic wave of a frequency used for long distant communication. 4. Explain the difference between a transverse wave and a longitudinal wave, and give examples of each. In a longitudinal wave, the vibration travels in the same direction that wave travels. Examples of longitudinal waves include: Sound, p-waves (earthquakes) In a transverse wave, the vibration direction is perpendicular to direction that wave travels. Examples include: Light/electromagnetic, (radio, microwave, xray, etc.), water waves, swaves (earthquakes). The major difference between longitudinal and transverse waves is their direction. Longitudinal waves move left to right while transverse waves move up and down. 5. Compare and contrast: light waves vs. sound waves Light waves are transverse and sound waves are longitudinal. Light waves can travel through a vacuum but sound waves cannot. Speed of light is nearly 300 million m/s while sound has a speed of about 340 m/s...

...prevent and control soil erosion are a part of geologic processes. Earth materials and processes affect our lives through our dependence on Earth resources; through geologic hazards such as volcanic eruptions, floods and earthquakes; and through the physical properties of the natural environment (Murck, B. W., Skinner, B. J., & Mackenzie, D. (2010)). Understanding Earth’s materials is important because we depend on its resources for building, soil for agricultural needs, energy resources, the air we breathe, and water needed to sustain life. Earth’s natural resources are not all unlimited some or many need management and conservation because they are not infinite. Chapter 2 1.

...THE UNIVERSE When we look up in the night sky we can see the stars and the moon. And because it is natural to be curious, we ask questions and we want answers. When our view was limited by what our eyes could see, the sky was our Universe. Then the telescopes deepened our view, photography enhanced it, and spectroscopy broadened it. The universe grew from a sky of stars to a realm of galaxies, to an expanding universe of galaxies. Many people believe that nature, the sun and moon, the star, even human beings never had a beginning. There is an endless, external cycle of birth, life and death that constantly repeats itself and it never began and will never end. In the Book of Genesis in the Bible, it was written that at first the world did not exist and that God is the only one who existed. So He created the world. The universe is the totality of everything that has ever existed. It is so large that it contains billions of stars, and all of the planets, galaxies and all of space. The study of the universe is called Cosmology. Traditional Views about the Universe 1. Geocentric Universe Greeks believed that the earth was a sphere that stayed motionless at the center of the universe or the geocentric (Earth-centered) view. Orbiting the earth were seven wanderers (planetai in Greek) including the sun, the moon and the known planets, Mercury, Venus, Mars, Jupiter and Saturn. Greece was centered as the “Golden Age” of early astronomy. Claudius Ptolemy created the book Almagest...

...minute. The wave energy dissipates over a wide area which results in a weak backwash. Destructive waves Destructive waves have a large wave height and short wave length. They have tall breakers that have a high downward force and a strong backwash. Their frequency is high with between 13 and 15 waves per minute. Their strong downward energy helps erode beach material and cliffs. The strong backwash results in narrow beach profiles. Tides Tides are the rise and fall of sea levels. Tides are caused by the gravitational pull of the moon and to a lesser extent the sun. When the earth, the moon and sun are aligned the gravitational pull is at it’s greatest. This creates a Spring tide. A Spring tide results in a high, high tide and low, low tide. This creates a high tidal range (difference between the highest and lowest tide) and results in stronger tidal currents than normal. Spring tides usually occur twice a month when there is a full moon. When the sun and moon are at a right angle to the earth we experience Neap tides. The gravitational pull of the sun partially cancels the moon’s. This results in a low, high tide and a high, low tide. This creates a low tidal range and results in weaker tidal currents than normal. Sub-Aerial Processes Sub-aerial process are land based processes which alter the shape of the coastline. These are a combination of weathering and mass...

...Cyber Crime Stacy Hendrix Grantham University Richard Sayles Introduction to Computer Crimes May 15, 2012 Cyber crime is the new breed of crime, which is either perpetrated using computers, or is otherwise related to the internet. Its origin can be traced to the growing dependence on computers in modern life in today’s society. Cyber crime has assumed criminal implications today as everything from microwave ovens and refrigerators to nuclear power plants is being run by or connected to computers. Today, the world is moving towards a point where everything from banking /stock exchanges, are traffic control, telephones to electric power, health care, welfare and education depends on software through the use of computers. This exponential growth; the increase in the capacity and accessibility of computers coupled with the decrease in cost, has brought about revolutionary changes in every aspect of human civilization, including criminal activity. The increased capacities of information systems today come at the cost of increased vu Inerrability. Information technology has become a production site for criminal opportunities of a variety that the brightest criminals of yore could not even begin to dream about. A cyber crime may be theft of valuable information services, communications in furtherance of criminal conspiracies, telecommunications piracy, electronic money laundering, electronic vandalism and terrorism, sales and investment...

For this chapter, Appendix B.3 may be particularly useful. Answers to odd-numbered problems appear in the back of the book. 1. A crystalline solid consists of atoms stacked up in a repeating lattice structure. Consider a crystal as shown in Figure P1.1a. The atoms reside at the corners of cubes of side L = 0.200 nm. One piece of evidence for the regular arrangement of atoms comes from the flat surfaces along which a crystal separates, or cleaves, when it is broken. Suppose this crystal cleaves along a face diagonal, as shown in Figure P1.1b. Calculate the spacing d between two adjacent atomic planes that separate when the crystal cleaves. [pic] Figure P1.1 Section 1.3 Density and Atomic Mass 2. Use information on the endpapers of this book to calculate the average density of the Earth.

...THE STUCTURE OF THE EARTH The interior structure of the Earth is layered in spherical shells, like an onion. These layers can be defined by either their chemical or their rheological properties. Earth has an outer silicate solid crust, a highly viscous mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core. Scientific understanding of Earth's internal structure is based on observations of topography and bathymetry, observations of rock in outcrop, samples brought to the surface from greater depths by volcanic activity, analysis of the seismic waves that pass through Earth, measurements of the gravity field of Earth, and experiments with crystalline solids at pressures and temperatures characteristic of Earth's deep interior. ASSUMPTIONS: The force exerted by Earth's gravity can be used to calculate its mass, and by estimating the volume of the Earth, its average density can be calculated. Astronomers can also calculate Earth's mass from its orbit and effects on nearby planetary bodies. Observations of rocks, bodies of water and atmosphere allow estimation of the mass, volume and density of rocks to a certain depth, so the remaining mass must be in the deeper layers. Earth's radial density distribution according to the preliminary reference earth model (PREM). Earth's gravity according to the preliminary reference earth model (PREM).

...What Is Selenium? Selenium (Se) is a trace mineral that is required by the human body and is of fundamental importance in ensuring good health. Selenium was discovered in 1817 by Jons Berzelius and takes its name from the Greek word Selene (the goddess of the moon). Until recently, selenium was a little-known trace mineral. International research on Selenium has established that it is an essential component of the human diet in the sustaining of good health and general well-being because of its protective and preservative characteristics. It has also been found that selenium deficiency may lead to increased susceptibility to disease and ill health. Organic And Inorganic Selenium Explained Selenium exists in two chemical forms in nature, Organic Selenium and Inorganic Selenium. Inorganic Selenium can be found in different minerals in the form of selenite, selenate and selenide as well as in metallic form. In contrast, in vegetable feed Organic Selenium is an integral part of amino acids. Therefore, in nature animals receive selenium mainly in the organic form. Research had shown that Organic Selenium is far more beneficial for us as our body absorbs and retain Organic Selenium at a better rate. Organic Selenium vs Inorganic Selenium Organic Selenium Inorganic Selenium • Exists in the form of seleno-amino acids, i.e. selenomethionine. • Exists in the form of mineral salt. • Is actively absorbed by amino acid routes. • Is passively absorbed from the small intestine. • More...

...approaches to nanomanufacturing, the top-down approach or the bottom-up approach. The top-down approach reduces large pieces of material down to the nanoscale. This approach uses more material and can lead to waste if excess material isn’t used. The second approach, the bottom-up approach, creates products by starting at the atomic or molecular level and building the products from the ground up. This process is very time consuming. With these two approaches there are new processes that enable nanomanufacturing which are (Manufacturing at the Nanoscale): 1. Chemical vapor deposition – a process where chemicals react to produce pure high-performance films. 2. Molecular beam epaxity – a method for depositing highly controlled thin films 3. Atomic layer epaxity – a method for depositing one atom thick layers on a surface 4. Dip pen lithography - a process where the tip of an atomic force microscope is "dipped" into a chemical fluid and then used to "write" on a surface. 5. Nanoimprint lithography –...

...INTRODUCTION The echinoderm class Holothuroidea consists of sea cucumbers, which can be described as worm-like organisms with elongated, soft bodies. Like most echinoderms, holothuroids have 5 rows of tube feet along their bodies. These tube feet aid the animal in attachment, locomotion and respiration (Pearse et al. 1987). Within the class Holothuroidea, there are about 1250 species, and these are distributed among 200 genera (Smiley et al. 1991). There is much variety among the habitats in which sea cucumbers reside. Some species, like Cucumaria fallax, inhabit quiet, still waters, while others, such as C. miniata, are found in areas that are constantly swept by tidal currents (McEuen 1988). Some holothuroids are tropical reef dwellers (Uthicke 1997); others live in temperate or polar waters (Hamel and Mercier 1995). Even the depth at which these animals can be found varies greatly. Many species live within the intertidal zone, but a few sea cucumbers live deep in the ocean, some among hydrothermal vents (Smirnov et al. 2000). Regardless of the environment in which they are found, sea cucumbers have become highly adapted to life in that environment, especially in their reproductive cycles. Sea cucumbers can reproduce through sexual reproduction as well as asexual reproduction. Each mode of reproduction has several environmental factors that have been proposed to control its timing. This paper will first introduce the two types of reproduction found in sea cucumbers. I will then...
