    These factors expressed in the question affect the population density of a country or location immensely. Firstly relief‚ when we talk about the relief we talk about highlands and lowlands. Although immediately we like to think that most of the world’s population live fairly low down it is in fact the case that 80% of the worlds population live 500 metres above the sea level‚ this is actually fairly high up. What we might have been thinking of are the mountainous areas of the world like the Andes

    conditions; low‚ medium‚ and high density. The effects of different population densities on the survivorship and reproduction of Daphnia are observed over a two-week period within a lab environment. Over the two week period‚ the numbers of parent Daphnia alive and dead are recorded daily‚ along with the amount of offspring produced each day. From the main parameter investigated‚ the net reproductive rate‚ the results of the experiment support that higher densities result in less successful reproduction

    or less than the volume of water it displaces. The second objective of the experiment was to produce a value for water density. It was expected that when additional mass was added to a floating vessel‚ it would displace more fluid and the increasing submerged volume of water could be measured‚ and a value for water density could be calculated using the equation . The density of pure water was assumed to measure 1000 kg/m³ at 4°C however it was also assumed that the tap water used in the experiment

    environmental issues and economic performance and population density Executive summary The main goal with the report was to analyse the relationship from 16 different countries on how‚ if any‚ CO2 emission per capita is getting affected by population density and GDP per capita by using descriptive statistics and regression. The conclusion is that CO2 emission per capita is affected by changes in GDP per capita and that population density has no significant relation to CO2 emission per capita.
