summary of factors influencing population

The inter-ionic attraction It is the intersection between the ions of the solute at low concentrations. It is not much at low concentrations the inter-ionic cone is very less, but at high concentrations it is appreciabl..

Low ionisation energy Ionisation energy is the amount of energy, which is required to remove the most loosely bound electron(s) from an isolated gaseous atom to form a positive ion. In forming an ionic bond, one atom must form a cation by losing one or more electrons. In general, eleme..

Ecology concerns with the associations and interactions of the organisms and the environment in general. The living place or dwelling place of an organism is called habitat. Within a given habitat there exists variations or micro habitats. In a given habitat we can observe physical (abiotic) enviro..

The mechanism of transmission of characters from the parental generation to the offspring is called heredity. The differences seen among members of a species and their offspring are described as variations. Genetics is the study of heredity, variations and the environmental factors..

>Sex is determined by various factors and in humans on the type of chromosomal fusion Microevolution is evolution on a small scale within a species or single population. It can be due to mutation, migration, genetic drift and natural selection Speciation is the evolutionary proc..

Summary - Asia has 60% of global population and continues to dominate the global population in next 50 years. Some countries in Europe have negative or zero growth of population. In India, U.P is a populous state but density of population ..

Factors Affecting Population - The size and density of a population are affected by various factors. Some of the important ones a..

Natality rate is the rate at which new individuals are added to a particular population by reproduction (birth of young ones or hatching of eggs or germination of seeds/spores..

Mendel postulated that there are certain physical entities called the factors that are responsible for the transmission of characters; these factors are now called gene..

Smallest unit of ecological hierarchy is the organism, while smallest and basic unit of taxonomic hierarchy is species. A group of individuals, having similar structural and functional characters, capable of potential interbreeding is termed as species. In nature all apecies exhibit cooperative and..
