The cell is the basic unit of all life. All living things-- tigers‚ trees‚ elephants‚ and men-- are made up of cells. A cell is alive-- as alive as you are. It breathes‚ takes in food‚ and gets rid of waste. It grows and reproduces‚ or creates one of its own kind. (Garrod 36) Most cells reproduce by dividing‚ so that there are two cells where there once was one. (Akkas 78) Every living thing is made up of one or more cells‚ and each of these cells was produced by an already existing cell. New cells

Introduction A hurricane is a tropical revolving storm. It is a very large circular area of low pressure‚ driven by evaporation from warm seas. In areas away from the Equator‚ air is drawn into the hurricane to replace the rising air. Owing to the Earth rotation‚ wind in a hurricane spiral inwards in an anti-clock wise direction. Wind speeds can reach 300km/ hour‚ although there is an area at the centre of the hurricane

Mitosis Biology Project Dania Abu Zahra‚ Hadeel Kashash‚ Nada Mubarak‚ Reem Al Ahbabi What is Mitosis? Mitosis is the process by which a cell‚ which has previously replicated each of its chromosomes‚ separates the chromosomes in its cell nucleus into two identical sets of chromosomes‚ each set in its own new nucleus. It is a form of nuclear division. It is generally followed immediately by cytokinesis. Mitosis and cytokinesis together define the mitotic (M) phase of the cell cycle—the division of

Geography Peru is a country located on the western part of South America just below the equator. The country is made up of a coastal plain in the west‚ tall mountains in its center (also called “The Andes”) and a jungle in the east that leads into the Amazon River basin. The highest point in Peru is Nevado Huascaran which is a mountain that is 22‚205 feet tall. The climate of Peru varies based on the landscape but it is mostly tropical in the east‚ desert in the west and temperate in the Andes

questions that relate to people interacting with earth‚ which are asked by geographers. • Latitude: Latitude lines are imaginary lines on the earth’s surface that run east and west around the globe and tell you your distance north or south of the Equator. • Longitude: Longitude lines are imaginary lines on the earth’s surface that run from pole to pole around the globe and tell you your distance east or west from the Prime Meridian. • Compass Rose: A symbol on a map used to display the orientation

Mitosis: During meiosis I‚ tetrads form‚ and crossing-over occurs during prophase I. This event does not occur during mitosis. During metaphase I of meiosis‚ tetrads align at the spindle equator. The paired chromosomes have a total of four chromatids each. During metaphase in mitosis‚ dyads align at the spindle equator. During the anaphase I of meiosis‚ the homologous chromosomes of each tetrad separate‚ and dyads move to opposite poles. During anaphase of mitosis‚ sister chromatids separate‚ becoming

temperate grassland‚ coniferous forest‚ temperate broadleaf forest‚ and tundra. The tropical forest can be separated into two categories; tropical rainforest and tropical dry forest. Both‚ tropical rainforest and tropical dry forest are found near the equator. The tropical rainforest is generally characterized by poor soil‚ high rainfall‚ and a high diversity of plants and animals. The tropical dry forest undergoes an annual dry season. Though‚ the average rainfall is adequate enough to enable growth of

Just how different and similar can the Brazilian and American cultures be? Brazil is located below the equator in South America‚ on the other hand‚ The United States of America is located above the equator in North America. Because of the difference in location‚ Brazil speaks Portuguese derived from Latin roots while Americans speak English derived from Germanic roots. Both cultures place emphasis in family. The American culture sees family as less important than a career. Americans have their twenty-four

Stacy Servoss Ms. Hines Eng. 090-D01 15 July‚ 2013 The Effects the Moon Has On the Ocean Tide The moon’s gravity affects tides on the earth. The sun and moon together pull on the earth’s oceans in different directions to create tides. But there are several other factors that complicate this process. Friction is the earth’s rotation and axis tilt on the sun and moon’s gravitational pull on the earth. This forces push on the earth’s atmosphere‚ creating high tides and low tides. The gravity
