population growth = accelerated degradation of natural resources = agricultural stagnation. -90% of households in Sub-Saharan Africa use wood-fuel as the staple source of energy. -Slow economic growth will impede the switch to non-wood fuels. -Hence the demand for wood-fuel would increase with population growth -Has important negative effects on rural women‚ health‚ nutritional patterns and soil conservation -Loss of animal and plant species due to shrinking forests Population growth and education

strength 1M HCl acid had a pH level of 3.12 (Table 3.1). Sample A2 to A4 remained in the pH 3 level‚ while sample A5 and A6 had a pH range of 4 (Table 3.1). The pH level for 1M HCl dilutions slightly increased between each sample (Table 3.1). The diluted solutions of 1 M NaOH showed a few unexpected results. The original solution of 1 M NaOH was at a pH level of 11.50 (Table 3.1). However‚ the pH of sample B2 increased to 12.81 (Table 3.1). The remaining samples had a decreasing pH pattern for each dilution

Survival skills Survival skills are techniques a person may use in a dangerous situation (e.g. natural disasters) to save themselves or others (see also bushcraft). Generally speaking‚ these techniques are meant to provide the basic necessities for human life: water‚ food‚ shelter‚ habitat‚ and the need to think straight‚ to signal for help‚ to navigate safely‚ to avoid unpleasant interactions with animals and plants‚ and for first aid. In addition‚ survival skills are often basic ideas and abilities

Investigation Aim: The aim of the investigation was to investigate the effect of substrate concentration Hydrogen Peroxide H O (in %) on the rate of reaction of the enzyme catalase (in 1/mean time). Prediction: As the substrate concentration (hydrogen peroxide) in % increases the rate of reaction in 1/mean rate increases until the solution becomes saturated with the substrate hydrogen peroxide. When this saturation point is reached‚ then adding extra substrate will make no difference. The

Bacteria Growth Requirements Microbiology Life as we now it has ended. What is left you ask? Well it is said the only thing that could survive an incident that could end our known way of life is a roach and a pack or Twinkies. In truth the great survivor would be microorganisms. Microorganisms can survive where most cannot due to their size‚ nutritional needs‚ energy requirements‚ and are very good at adapting to different environments (Black 2008). Microorganisms require two things to

In this report‚ the concentration of total protein and albumin were calculated with the interpretation of a standard curve. To determine the concentration of total protein in human serum‚ a total protein assay was performed by using the Biuret reagent. Proteins react to this compound because it contains two amide bonds. When the Biuret reagents is introduced to a sample of protein‚ it forms a blue or violet complex. The concentration of albumin in human serum is determined by using the Bromocresol

Temperature Effects on Labor Productivity: A Cross-Country Approach Introduction Intro into the topic Hypothesis I will test the hypothesis that higher temperature will adversely affect labor productivity in a country. Outline Purpose The purpose of this paper is to check the effects of temperature on labor productivity to conclude that climate change will have a severe impact on labor productivity in the future. It can be thought of as a domino effect. To begin with‚ populations are increasing

Environmental factors effecting motor skill development Child development is defined as to how a child ables itself to complete more difficult tasks as they grow in age. Development is often confused with growth‚ which refers to a child’s tendency to grow bigger in size. Parents can become concerned easily when a child’s developmental skills take longer then the “normal” or when pressures of milestones are not satisfied “on time”. Developmental milestones are functioning tasks or skills that should
