Hadley cell

Atmospheric Global Circulation is the movement of air caused by solar energy and the interaction of warm and cold air - this convergence forms cells or belts over the Earth’s surface. George Hadley (1685–1768) a British physicist and meteorologist, who first described this theory in 1753, did so using what is known as the Single-Cell Atmospheric Global Circulation Model or Hadley Cell (The Editors of Encyclopædia Britannica, 2007). Hadley’s Single-Cell theory failed to consider the Coriolis Effect which prevents air from traveling directly to the poles and could not explain the westerly winds in the mid-latitudes (The Editors of Encyclopædia Britannica, 2007). In the 1850’s research provides greater insight to the westerlies and polar easterlies,…

Discovering a new world below the ocean intrigues me. I have never been one for loving ocean creatures, but I do enjoy learning about the world below us. I found several facts interesting as I read the articles including: how osmosis and salinity functions, how seawater cells move, how pH affects the ocean, how decomposition works in the environment, how upwelling stirs up nutrients, and how water temperature affects organisms. One of the interesting facts discusses why osmosis and salinity…

species (Miller & Hammond, 2003). The larvae digestive system begins with the mouth, leads to the esophagus, and to the malpighian tubules, where nitrogenous wastes are filter and ion regulation takes place. The malpighian tubules lead toward the hind intestine and finally to the rectum, through which the wastes are eliminate (Douglas,1989). Caterpillars grow through time and increase in size each time they shed their skins which also known as molt. After molting, their skin is shed and develop…

She moved to America in September and enrolled in South Hadley High School in Massachusetts. When she enrolled in South Hadley she had a very good status, a lot of boys were attracted to her. She started dating a boy, Sean Mulveyhill, soon the relationship ended. Phoebe soon went to a new boy Austin Renaud, after they broke up, their ex girlfriends were out for her. They started bullying her both of the ex girlfriends and their best friends then they were called the “South Hadley Six”. They…

motor proteins attached to the vesicles. Microtubules can also expand or shrink in length in order to establish dynamic structures that can efficiently change the internal organization of the cell, and capture organelles through the cytosol. Intermediate filaments are made up of the protein keratin. Their primary function is to strengthen the internal structure of a cell. Microfilaments are the smallest among the three cytoskeletal filaments. They consist of protein actin. Microfilaments are…

In Aristotle’s view, everything in this world can be categorized. Living beings include plants and animal. The plant has nutritive soul and the animal process both nutritive soul and perceptive soul. If we discuss animal further, we can divide animal into rational animal, which is human, and non-rational animal. The essential feature of “being an animal” is perception. From the Aristotle Introductory Reading: “413b2: What makes something an animal is primarily perception.” Perception is…

Genetic Engineering is the modification of an organism 's genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. With this new, rapidly growing, technology we are now able to do things that we once thought were impossible. In Ethics and the New Genetics, the Dalai Lama addresses problems that we need to consider as we continue to explore this microscopic world that we have…

evolutionary time that has occurred. Heat shock proteins (HSPs) are in a class of proteins called molecular chaperones. (Kiang, J.; G, Tsokos. 1998). They are present in both eukaryotes and prokaryotes, in the cytosol, mitochondria, endoplasmic reticulum and the nucleus. In humans they have a relatively long half-life of about 2 days (Baneyx, F. 2008). HSP70 are a specific type which are normally found in very low amounts within a cell, they can be expressed in response to external stimuli.…

In the case of a missing limb, the scientists would take stem cells from the patient and us it for the base of the new limb. If Humans mastered cloning then they could use that technology and the patient’s stem cells to construct a new arm, leg, ear, or whatever was missing without worrying too much about the patient’s body rejecting the foreign limb. In the case of organs the process would be more or less the same, if someone was dying of liver cancer, it would be possible to take out his…
