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

“Discuss the Causes and Effects of Economic Growth” Economic Growth is where goods and services maximise in value over a period of time. This is measured by Real Gross Domestic Product (GDP) which is defined as “The total market value of all final goods and services produced in a country….equal to the total consumer‚ investment‚ and government spending‚ plus the value of exports minus the value of imports.”(www.Investorwords.com) In turn this is measured by the level of aggregate demand in the

Effect of Different Microwave Doses on Vicia faba Germination‚ Growth and Genetic makeup Problem: Some areas are affected by high frequencies of microwaves; this affects plant growth‚ germination and genetic makeup‚ which leads to a loss in crop yield‚ including one of the major crops of high economic importance‚ the Vicia faba. Abstract: Plants and their stresses have been of very great importance lately. Since there are many kinds of stresses‚ we only studied one‚ but a very important

THE EFFECTS OF AMMONIA AND VINEGAR ON RADISH PLANTS 1 The Effects of Ammonia and Vinegar on Radish Plants THE EFFECTS OF AMMONIA AND VINEGAR ON RADISH PLANTS 2 Abstract INTRODUCTION OF GROUP Plants are one of the most complex organisms; how they grow is very complex and it is important to see how they grow to even how they die. We first had to propose a question and test it to see if it was profound enough to test. Our group decided to see how different chemical

In which some of them at low concentration are compulsory micronutrients‚ while the same at higher concentrations such as Cd‚ Hg‚ As are intensely toxic to the metabolic activities of the plants (Reeves and Baker‚ 2000; Fernandes and Henriques‚ 1991).

Abstract on Determining the Photosynthetic Activity in Plants Using Different Wavelengths of Light using Chromatography and a Spectrophotometer In this experiment‚ the separation of particular pigments‚ contained within a fresh spinach leaf‚ were examined. Paper chromatography is the process of separating certain molecules‚ or pigment molecules‚ based upon their polarity. Four different pigments were examined from the spinach leaf: chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and carotene. Based

An experiment was carried out at the Horticulture Farm‚ Bangladesh Agricultural University‚ Mymensingh during 1998-99 growing season to study the effect of nitrogen and plant spacing on the growth and yield of potato (var. Diamant). Different nitrogen levels viz. 0‚ 127.0‚ 190.5 and 254.0 kg N/ha significantly influenced plant height‚ foliage coverage‚ number of main stem per hill‚ days required for 80% maturity of the crop‚ fresh weight of haulm (g/hill)‚ number of tubers per hill‚ weight of tubers

Temperature effects on the growth of microorganisms Introduction: The purpose of this experiment was to determine the effects that temperature has on three different organisms. Temperature is one of the most important environmental factors affecting growth and survival of microorganisms². The three organisms used where Escherichia coli‚ Pseudomonas fluorescens‚ and Bacillus stearothermophilis. Most bacteria grow within a particular temperature range. The minimum growth temperature is
