...Organism Physiology Paper Markesan Norfleet April 16, 2012 BIO/101 Alison Barrett Organism Physiology There are many different types of organisms that could have been chosen for this assignment. Organisms are any living thing such as fungus, animals, plants, or micro-organism. It is a body made up of organs, organelles, or other parts that will work together to carry on the various process of life. The organism I chose for this assignment is jellyfish. The name “Jellyfish” is a term that refers to the enormous variety of creatures that live in the sea. Some jellyfish live in fresh water. Jellyfish is an animal that belongs to phylum cnidarians, that is included in the class of scyphozoan. They are members of two groups that float freely or swim. The two groups are cnidarians and ctenophores. The type of jellyfish in the diagram is the scyphozoan medusa. They are the jellyfish that is commonly found washed up on seashore (Buiding Bodus of Jelly-Jellyfish, 2012). Jellyfish has two major body forms. The first body form is the polyp stage. This stage is characterized by the non-moving stalk that will catch food floating by. The second major body form is called the medusa stage. This form is characterized by the round body with hanging tentacles that will catch food (Hernandez, 2012). This form is more familiar to most people. The jellyfish feeds off of small fish and zooplankton that has been caught in their tentacles. They also have an incomplete digestive system, this...

...Organism Physiology Paper Sarah Szafranski BIO / 101 6/26/2013 Alena Aviles There are many organisms that have survived throughout the history of the earth by adapting to ever-changing environments. One of these, dating back over 220 million years, is the turtle. With over 250 different species still around, this reptile has established a legacy of perseverance and resiliency. They have overcome numerous adversities such as earthquakes, floods, fire, droughts, predators, disease, and urban sprawl. Turtles can be found in every ecosystem spanning the globe from the tropics, the desert, to the ocean. While turtles have been known to predominantly live in the water, they have adapted to conditions on land. Their species have evolved over the years through breeding and acclimation to their environment. This evolution includes changes to their physical characteristics such as shells, shapes, and color, but also incorporates psychological changes such as breeding habits, defensive tactics and migration patterns. My favorite of these would be the majestic sea turtle. Sea turtles can be found in just about every sea throughout the world regardless of fresh water, salt water, light water, or brackish water. As seaworthy as they are, sea turtles still have a strong tie to land and coastal habitats. As seen in the diagram below, the sea turtle has many of the same organs and functions of other mammals however; their bodies are shaped hydrodynamic, meaning that they can...

...Save Our Beaches! The Study Behind Coastal Pollution Plastic Pollution is a significant contributor to the non-point source pollution found in the Monterey Bay and around the world. While terms such as Marine Debris and Ocean Trash have been used to describe the garbage that enters the ocean, a growing number of scientists, researchers and marine-based organizations have adopted the term Plastic Pollution not only because 90% of floating ocean trash is plastic, but because the term pollution highlights that we are dealing with a pervasive substance that contaminates water, the cells of organisms, and knows no boundaries. (Plastic Pollution, n.d.) 80% of plastic pollution that enters the ocean originates from land. Common sources include: recreational beach users, people who drop litter on sidewalks and streets, plastics manufacturers and transporters, illegal dumping, and areas with inadequate trash receptacles. All land-based plastic pollution has the potential to become ocean pollution. Plastics easily blow into the ocean or washed down storm drains that flow directly to the Bay, and oceans around the world. (Marine Problems: Pollution, n.d.) Marine animals often mistake plastic pieces for food. For example, bird species such as pelicans or albatross will mistake pieces of plastic for small fish. Once the animal ingests the plastic, their body cannot digest it. The plastic item will remain in the animals’ stomach causing the animal to feel full. Thus the animal will eventually...

Reconstructing Phylogenies • 1859-1950- No coherent empirical methods • 1950-1966- Emergence of Phylogenetic Systematics • Phylogeny by discovery of the order of evolutionary innovation Ribotyping • Fingerprinting or sequencing RNA • Many diseases have unknown causes • However, diseased tissues can be ribotyped. (Wiley Death Fish) • This process involves extracting DNA from diseased tissues and then sequencing the DNA that codes for rRNA. • If a disease agent such as a bacteria is present, then we will get ribosomal DNA sequences from the host (you) and the bacteria (the infection agent). Ribotyping: Phylogeny matching • Once we have the rDNA sequences, we can plug them into a sequence matrix of all life and see where our unknowns appear on the tree of life.

...Master Diver Diving Equipment Open circuit demand scuba is the most commonly used by recreational divers, but closed circuit and semi-closed rebreathers are now available. Test Pressure: the pressure to which the cylinder is subjected to during hydrostatic testing. For a 200 bar cylinder it is 300 bars, for a 232 bar cylinder it is 348 bars. If internal inspection reveals corrosion, it may have to be cleaned by tumbling. The tumbling process involves filling the cylinder approximately half full of an abrasive material such as carbide chips, or aluminum oxide chips, and rotating it for a number of hours. A dual valve for a single cylinder, known as a Y-valve, or an H-valve, allows a diver to mount 2 regulator systems on a single cylinder. The first stage reduces cylinder pressure to an intermediate pressure (or low pressure) of approximately 90-150 psi (6 to 10 bar). The second stage reduces the intermediate (low) pressure to ambient pressure. Because of their tendency to fail in a closed position, upstream valves are rare in modern scuba regulators. In a Balanced Valve regulator the operation of the regulator is independent of the cylinder or applied pressure. (Breathes the same at low tank pressure) The internal valves of scuba regulator first stages are available in 2 basic types, diaphragm and piston. The main valve of a Pilot Valve regulator is opened and closed with air pressure, rather than mechanical leverage. Some regulators may...

...The Internet Encyclopedia of Philosophy - http://www.iep.utm.edu Philosophy of Sexuality Among the many topics explored by the philosophy of sexuality are procreation, contraception, celibacy, marriage, adultery, casual sex, flirting, prostitution, homosexuality, masturbation, seduction, rape, sexual harassment, sadomasochism, pornography, bestiality, and pedophilia. What do all these things have in common? All are related in various ways to the vast domain of human sexuality. That is, they are related, on the one hand, to the human desires and activities that involve the search for and attainment of sexual pleasure or satisfaction and, on the other hand, to the human desires and activities that involve the creation of new human beings. For it is a natural feature of human beings that certain sorts of behaviors and certain bodily organs are and can be employed either for pleasure or for reproduction, or for both. The philosophy of sexuality explores these topics both conceptually and normatively. Conceptual analysis is carried out in the philosophy of sexuality in order to clarify the fundamental notions of sexual desire and sexual activity. Conceptual analysis is also carried out in attempting to arrive at satisfactory definitions of adultery, prostitution, rape, pornography, and so forth. Conceptual analysis (for example: what are the distinctive features of a desire that make it sexual desire instead of something else? In what ways does seduction differ from nonviolent rape...

Akyildiz The Broadband Wireless Networking (BWN) Laboratory, School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, GA, USA a r t i c l e i n f o a b s t r a c t Nanotechnology is an emerging field of science devoted to provide new opportunities in a vast range of areas. In this paper, different techniques are proposed to enable the long range interconnection of nano-machines, deployed over distances from a few centimeters up to several meters. Long range nano-communications will enable the development of applications that could not be implemented using other techniques. The usage of both short-range nano techniques and long range micro techniques are not practical or are unfeasible for a huge application scope. Biologically inspired research provides promising features to long range communication, such as very low power consumption and biocompatibility. In this paper, several bio-inspired techniques are discussed following a twofold taxonomy divided according to whether a fixed physical link is required for signal propagation or not, i.e., either wired or wireless communication. In the first group, pheromones, spores, pollen and light transduction are discussed. In the second group, neuron-based...

...Guns, Germs and Steel Page 1 GUNS, GERMS, AND STEEL: The Fates of Human Societies By Jared Diamond, 1997 About the Author: Jared Diamond is a professor of physiology at UCLA School of Medicine. He is a recipient of a MacArthur Foundation Fellowship and was awarded a 1999 National Medal of Science. He is also the author of The Third Chimpanzee. SUMMARY The book asks and attempts to answer the question, once humankind spread throughout the world, why did different populations in different locations have such different histories? The modern world has been shaped by conquest, epidemics, and genocide, the ingredients of which arose first in Eurasia. The book’s premise is that those ingredients required the development of agriculture. Agriculture also arose first in Eurasia, not because Eurasians were superior in any way to people of other continents, but because of a unique combination of naturally occurring advantages, including more and more suitable wild crops and animals to domesticate, a larger land mass with fewer barriers to the spread of people, crops, and technology, and an east-west axis which meant that climate was similar across the region. The book is well written and contains not only information about the history of cultures around the world, but excellent descriptions of the scientific methodologies used to study them, from how archeologists study the origin of agriculture to how writing evolved to how linguistics can trace the movements of peoples across huge geographic...

...Chapter 1 The Dimensions of Psychology Summary: Psychology is an academic and applied discipline that involves the scientific study of mental functions and behaviors. Psychology has the immediate goal of understanding individuals and groups by both establishing general principles and researching specific cases, and by many accounts it ultimately aims to benefit society. In this field, a professional practitioner or researcher is called a psychologist, and can be classified as a social, behavioral, or cognitive scientist. Psychologists attempt to understand the role of mental functions in individual and social behavior, while also exploring the physiological and neurobiological processes that underlie certain cognitive functions and behaviors. Structuralism was the first school of psychology and focused on breaking down mental processes into the most basic components. Researchers tried to understand the basic elements of consciousness using a method known as introspection. Wilhelm Wundt, founder of the first psychology lab, was an advocate of this position and is often considered the founder of structuralism, despite the fact that it was his student, Edward B. Titchener who first coined the term to describe this school of thought. Functionalism formed as a reaction to the structuralism and was heavily influenced by the work of William James and the evolutionary theory of Charles Darwin. Functionalists sought to explain the mental processes in a more systematic and accurate...
