Nitrogen cycle A simple and complete diagram of the nitrogen cycle. The blue boxes represent stores of nitrogen‚ the green writing is for processes that occur to move the nitrogen from one place to another and the red writing are all the bacteria involved. The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms. This transformation can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation

The Cell Cycle Mitosis: the process by which cells reproduce themselves‚ resulting in daughter cells that contain the same amount of genetic material as the parent cell. Interphase Prophase Metaphase Anaphase Telophase Cytokinesis Cell Division Occurs in a series of stages of phases Interphase occurs before mitosis begins Chromosomes are copied (# doubles) Chromosomes appear as threadlike coils (chromatin) at the start‚ but each chromosome and its copy(sister chromosome) change to sister

The organisational culture of a business is the collective behaviours of the individuals in a company and the way in which they strive to succeed. Business failure refers to a company ceasing operations following its inability to make a profit or to bring in enough revenue to cover its expenses. A profitable business can fail if it does not generate adequate cash flow to meet expenses. But what are the reasons for business failure? Is it predominantly due to the organisational culture of a company

where does the water cycle gets its energy from? the water cycle gets the energy from the sun. why do we need the water cycle? since 97% of the earth is covered by salt water we can not drink it. we can remove salt from water but it could be very expensive. how does water get into oceans? when clouds can’t hold any more water it comes as precipitation and lands in the ocean. what is the water cycle made up of? it is made up of six different traits. condensation‚infiltration‚runoff‚ evaporation‚ precipitation

CHAPTER 12- THE CELL CYCLE I. Concept 12.1- Cell division results in genetically identical daughter cells A. Overview 1) The continuity of life is based on the reproduction of cells or cell division. 2) The cell division process is an integral part of the cell cycle‚ the life of a cell from the time it is first formed from a dividing parent cell until its own division into two cells. B. Cellular Organization of the Genetic Material 1) A cell’s endowment of DNA‚ its genetic

CHAPTER ONE INTRODUCTION 1.0 BACKGROUND OF THE STUDY Menstrual cycle is a process experienced by every female at one point in their life cycle. In the olden days a young lady experiences her first menstruation in her late teens or early twenties. In recent times‚ however‚ some begin their menstrual cycle as early as nine years. The age at menarche (the first time a girl or a young woman menstruates) is widely considered as an important landmark in sexual maturity. However it varies widely between

The cell cycle‚ or cell-division cycle‚ is the series of events that take place in a cell leading to its division and duplication that produces two daughter cells. In cells without a nucleus‚ the cell cycle occurs via a process termed binary fission. In cells with a nucleus‚ the cell cycle can be divided in three periods: interphase—during which the cell grows‚ accumulating nutrients needed for mitosis preparing it for cell division and duplicating its DNA—and the mitotic phase‚ during which the

Hydrological Cycle Hydrological cycle is the process that involves the continuous circulation of water in the Earth-atmosphere system. The hydrologic cycle is a conceptual model that describes the storage and movement of water between the biosphere‚ atmosphere‚ lithosphere‚ and the hydrosphere. Water on our planet can be stored in any one of the following major reservoirs: atmosphere‚ oceans‚ lakes‚ rivers‚ soils‚ glaciers‚ snowfields‚ and groundwater. Water moves from one reservoir to another by
