Introduction. In Biology, Human Population Growth Is Defined

Introduction In biology, human population growth is defined as the increase of the number of individuals per a population. Human population growth can be affected by several different factors such as life expectancy and fertility rates. Life expectancy and fertility rates are the driving forces behind the growth of human population. Life expectancy refers to the average period in which an individual is expected to live. Fertility refers to the number of children a woman will bear within her lifetime. A factor that greatly affected the human population growth in China was the one child policy. The one child policy was implemented during the 1970s in an attempt to gain to control over China’s rapidly growing population. A policy such as†¦show more content†¦The medium range proposed by the United Nations has been corrected over the years to slightly above what it was projected to be, meaning that the world population has grown more rapidly than first projected (1). Toda y, China stands as the most populated country containing 1,386,814,594 individuals, making China 18.47 percent of the world’s total population according to the United Nations most recent estimations (3). Although, China seems to have their population under control now, during the 1960s and 1970s China was faced with the issues that arise from overpopulation. In 1979 China housed 25 percent of the world’s population (4). Two thirds of China’s population was under the age of thirty at that time and the baby boomers of the 1950s and 1960s were venturing into the procreative phase of their lives (4). Due to the rapid population growth rate that the baby boomers were causing with their own babies made Chinese government take notice. The Chinese government saw it essential to attempt to contain the rapid growing population. The Chinese government responded to this overpopulation problem by implementing the one child policy. The graph below illustrates China’s p opulation of infancy up until the age of 64 in relation to world in the form percent and years (8). . The one child policy was aimed at regulating and reducing the size of a Chinese family. The one child policy stated that families must obtain a birth certificate before the child was born (6).Show MoreRelatedThe Impact of Computer Science on Health Care Medicine1283 Words   |  6 PagesThe Impact of Computer Science on Health Care amp; Medicine Abstract Computer science can be defined as the systematic study of algorithmic processes, their theory, design, analysis, implementation and application. Its functions in the modern society today expand far beyond the uses one could even begin to imagine. Specifically, there is an increased influence in its practical application in the field of medicine. In recent times, an interdependent relationship between medicineRead MoreThe Importance Of Drug-Drug Interactions1176 Words   |  5 Pagesdrugs interact with the same gene product. The literature of biological studies contains most of the available information about gene-drug relationships. Identifying drug-drug interactions is an important and challenging problem in computational biology and healthcare research. One approach that has been tried and has been successful is text mining. It provides an attractive solution for identifying gene-drug relationships and aggregating them to predict novel DDIs. There are accurate, structu redRead MoreOceanic Pollution : A Major Issue Within The Modern Study Of Marine Biology1645 Words   |  7 PagesOceanic plastic pollution is a major issue within the modern study of marine biology. The main focus of many studies about oceanic pollution are within the Pacific Ocean. The Pacific Ocean holds much of the plastic pollution due to its location near costal countries along with being the main transportation for many exported goods. This topic has sparked interest because of the rapid growth of this problem will affect many within one’s life time along with changing oceanic life. Oceanic plastic pollutionRead MoreLab Report : Lighting Up With Tetrahymena. Katy Snider.

Tetrahymena cells nourish through a process called phagocytosis. Phagocytosis is when the cell engulfs anything in its path using the cell’s cytoplasm. In this experiment, through the use of a control, and low and high concentration of tobacco extract it was determined that cigarette extract inhibitsRead MoreThe Theory Of Evolution Of A Population Over A Number Of Continuous And Successive Generations1539 Words   |  7 PagesEvolution is the change in genetic composition of a population over a number of continuous and successive generations, which may have resulted from natural selection, inbreeding, hybridization, or mutation. (Biology Online, 2008). This change occurs when there is genetic variation, a variation of genomes between members of species, or groups of species thriving in different areas as a result of genetic mutation. (Biology Online, 200 9). The two major mechanisms considered to be the driving forceRead MoreCloning the Metagenome to Access the Biodiversity of Unculturable Bacteria 1461 Words   |  6 PagesIntroduction Being the essential part of earth’s microbiota and their involvement in chemical, physical and biological transformations, bacteria are considered as a very important group of microorganisms. Those bacteria which cannot be grown easily on artificial nutrient media are referred as unculturables. The evidence for the presence of yet to be cultivated bacteria came from the molecular data. The capability to obtain DNA sequence information from an environmental sample by PCR manipulationsRead MoreThe Benefits of Genetic Engineering Essay1459 Words   |  6 Pagesdo humans have the right to make life? Most of the concern comes from the fear of control over the production and development of human beings. But, those who are against cloning would most likely look the other way if they needed gene therapy after receiving a grim diagnosis. There are many aspects of genetic engineering and to thoroughly understand it looking into each is absolutely necessary. In order to understand genet ic engineering, the key terms in this controversy that must be defined areRead MoreEssay On Glioblastoma1349 Words   |  6 Pageschemotherapeutic resistance is almost universal and GB is no exception, thus reflecting in high mortality and morbidity rates4.

For instance, a fish gene can be transferred to a plant; human genes can be transferred to animals. A gene is a section of DNA on the chromosome, usually about a thousand units in length. A gene is a molecular unit of heredity of a living organism which holds the information to build and maintain an organism’s cells and pass genetic traits to offspring. The field of Human Biotechnology has many aspects of which Human Genetic Engineering is one, known for the power to improve an individual
