Neurophysiology Virtual Lab pilot Neurophysiology is the study of nervous system function. Primarily, it is connected with neurobiology, psychology, neurology, clinical neurophysiology, electrophysiology, biophysical neurophysiology, ethology, neuroanatomy, cognitive science and other brain sciences. Neuron Simulation Virtual Lab pilot This lab uses a graphical web-based Neuron simulator and models a section of excitable neuronal membrane using the Hodgkin-Huxley equations. Various experiments will deal with the several parameters of Hodgkin-Huxley equations and will model resting and action potentials, voltage and current clamp, pharmacological effects of drugs that block specific channels etc.

Objectives Describe the special nature of the Earth as a "water planet" and recognize its place in the universe. Compare some of the current theories concerning the origin of the planet and the waters that cover its surface. Discuss the co-evolution of the earth and its resident biology. Discuss basic chemical oceanography in terms of the special properties of water and dissolved salts and dissolved gases.

Biology | Cottey College

Describe the motions of the seas — as currents, waves and tides — in terms of causes and their influences and effects upon the land. Recognize the adaptations of marine organisms to special properties of the ocean such as light and sound.

Identify the features of special animal groups such as sharks, protozoa and marine mammals. Realistically assess the resources of the sea in terms of minerals, energy and food.

Discuss the reasons for and the means by which humankind uses and misuses marine resources. Describe areas of intense scientific interest and public concern such as plate tectonics and earthquake predictions, the impact of ocean pollutants, climate fluctuations, cetacean intelligence, and ocean technology.

Identify the causes of marine pollution and understand the problems of containment and alleviation. Content Outline and Competencies: The Water Planet A. Define oceanography and list and briefly describe at leave five branches of this science.

Discuss science as a way of understanding the universe and accumulating knowledge. List the steps in the scientific method and compare and contrast the terms, hypothesis, theory and law as they are used in science.

Discuss the big bang theory of the origin of the universe including at least two types of evidence that support this theory.

Explain how and when the sun, solar system, Earth and oceans formed. Compare and contrast the early voyages of the Polynesians, Vikings, Greeks and Chinese, especially their motivations, vessels and seafaring skills. Recognize the importance of record-keeping and catography to voyaging, and the historical role of the Library of Alexandria.

List some of the major contributions to early voyaging of Prince Henry, Magellan and Columbus. Recognize the role of Captain James Cook in the history of marine science, and be aware of his three major voyages.

Describe the United States Exploring Expedition, its objectives and accomplishments, and its importance in bringing in the United States into the field of oceanography. Describe the Challenger Expedition and its major contributions in marine science. Chronicle the rise of land-based oceanographic institutions, from the early beginnings in Naples ad Monaco to the major facilities now operating in the United States.

List the disciplines in which marine research is being done today, as it relates to recent advances in data gathering and technology.


Making the Pieces Fit A. Describe the layered structure of Earth and understand how the structure was determined through the study of seismic waves.

Explain the concepts of buoyancy and isostatic equilibrium and their relationship to continental drift. Understand the source of convection and the role it plays in plate tectonics. Compare and contrast the terms continental drift, seafloor spreading and plate tectonics. Explain the evidence, both direct and indirect, for plate tectonic theory.

The World in Motion A. Describe the three major types of plate boundaries and discuss specific examples of each. Describe the formation, movement and fate of the Hawaiian Ridge and Emperor Seamounts and explain how these features support the theory of plate tectonics.

Discuss the formation of guyots and terranes and how each is related to tectonic movements. Compare and contrast deep and shallow earthquakes and describe the Wadati-Benioff Zone. Explain how the patterns of paleomagnetism, seafloor age and sediment thickness contribute to an understanding of tectonic theory.

Summarize the major types of evidence that support the theory of plate tectonics and list at least five significant unanswered questions about this process.Bacteria and fungi occur as individual, free-floating (planktonic) cells or clustered together in aggregates of cells (biofilms).

A microbial biofilm is ‘a structured consortium of microbial cells surrounded by a self-produced polymer matrix’ In addition to microorganisms, components from the host, such as fibrin, platelets or immunoglobulins, may be . Aseptic technique is vital in reducing the morbidity and mortality associated with surgical infections.

Description Aseptic technique can be applied in any clinical setting. Pathogens may introduce infection to the patient through contact with the environment, personnel, or equipment. AGM FUNDAMENTALS OF MICROBIOLOGY 1+1. Theory. Definition and scope of Microbiology - Spontaneous generation theory - Germ theory of diseases - Contributions of Antonie Van Leeuwenhoek, Louis Pasteur, John Tyndall, Robert Koch, Edward Jenner, Joseph Lister, Alexander Fleming and Waksman.

The aseptic techniques described here control the opportunities for contamination of cultures by microorganisms from the environment, or contamination of the environment by the microorganisms being handled. There are some general rules to follow for any aseptic technique.

Without aseptic technique growth of microorganisms on the nutrient agar is observed but not in nutrient broth which is clear as initial condition. By the end of this experiment, students learnt on how to perform microbiological work by maintaining the laboratory condition, methods and techniques which will render sterility called aseptic technique.

Aseptic technique is a fundamental and important laboratory skill in the field of microbiology. Microbiologists use aseptic technique for a variety of procedures such as transferring cultures, inoculating media, isolation of pure cultures, and for performing microbiological tests.
