Cardiac Cycle The cardiac cycle describes the coordinated and rhythmic series of muscular contractions associated with the normal heart beat. The cardiac cycle can be subdivided into two major phases‚ the systolic phase and the diastolic phase. Systole occurs when the ventricles of the heart contract. Accordingly‚ systole results in the highest pressures within the systemic and pulmonary circulatory systems. Diastole is the period between ventricular contractions when the right and left ventricles

WATER CYCLE Water Cycle‚ also known as hydrologic cycle‚ is a process that is constantly recycling the Earth ’s supply of water. This is important because humans‚ animals‚ and plants all need water to survive. It is controlled by the sun‚ which produces energy in the form of heat. This heat energy causes the water in the world ’s oceans‚ lakes‚ etc. to warm and evaporate. As the water is heated‚ it changes its phase from liquid to gas. This gas is called water vapor and this process is called

. Many products and services often pass a life cycle while there are many shapes depending on their industries. They newly emerge in the society‚ start to sell to be widespread‚ become saturated in the market and then gradually get out of date. This sequence of product and service is called the product life cycle. Smartphone also passes such natural path. According to the next web (2011)‚ first smartphone brand was Ericsso’s GS88 in 1997. A touchscreen smartphone‚ which is widespread now‚ was launched

الله الرحمن الرحيم السلام عليكم ورحمة الله وبركاته Water cycle The Earth ’s water is always in movement‚ and the water cycle‚ also known as the hydrologic cycle‚ describes the continuous movement of water on‚ above‚ and below the surface of the Earth. Since the water cycle is truly a "cycle‚" there is no beginning or end. Water can change states among liquid‚ vapor‚ and ice at various places in the water cycle‚ with these processes happening in the blink of an eye and over millions

The Cell Cycle Brittany Jameson Vista College Abstract The cell cycle is made up of five steps. These steps are interphase‚ mitosis‚ cytoplasmic division‚ cell differentiation‚ and cell death. During mitosis there is a series of four stages. The Cell Cycle To start the cell cycle the cells first go through a step called interphase. During this step the cell grows and synthesizes new molecules and organelles. In the S phase the DNA of the cell is replicated in preparation for cell division

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 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
