The current estimate of the worldwide human population at this moment is 7‚241‚862‚395. For every person who dies during the next three days‚ somewhere around the world a baby will be born who will‚ physically speaking‚ replace that death. With that being said there are 108 deaths per minutes‚ 155‚911 deaths per day and 56‚907‚606 per year. After all of those replacement births take place‚ 684‚000 additional births will occur. Every Minute of the day there are 267 births so that means every day

The data collected from the number of each type of macroinvertebrate was calculated to determine the Modified Family Biotic Index‚ percent contribution of dominant family‚ and EPT Index number for each of the three collection sites. The number of organisms and families of macroinvertebrates along with the calculated data can be seen in Table 1. Other sets of data was recorded and compared to test the stream quality at Pricket’s Creek. The water temperatures (°C) were 16.76 ± 2.32 (mean ± St. Dev

Introduction: One of the major problems the industrialized world is facing today is the contamination of soil‚ groundwater‚ sediments‚ surface water and air with hazardous and toxic chemicals. The long-term production and use of different petroleum derivatives have caused widespreadcontamination of soil around facilities handling them (Barbee et al.‚ 1992). The need to remedy these contaminated environments has led to the development of a number of technologies such as bioremediation (Head‚ 1998)

Introduction Emerging infectious diseases have been increasing incidence and are a key threat to wildlife and human health. Influenza is one of the most common diseases‚ causing millions of severe illnesses and huge number of deaths per years. Recent concerns were focused on H5N1 avian influenza virus that was first isolated in a domestic goose in China in 1997 due to its high case of death rate (Lucchetti‚ Roy & Martchvae‚ 2008). Influenza viruses are single-stranded RNA viruses of which 3 types

Population Ecology Ingrid Rhody BIO/101 March 7‚ 213 Kirsten Hagen MS Population Ecology Population ecology is the affect of a populations density and extension. When a group of single species occupy the same general area it is known as a population. This group of species will rely on resources and the same environmental atmosphere. The number of species within a group that occupy the same area or habitat is known as population density. Some ecologists use different types of techniques
