What are the two factors that affect the growth rate of any population?

There are three factors that determine the size of the confidence interval for a given confidence level. These are: sample size, percentage and population size. The larger your sample, the more sure you can be that their answers truly reflect the population.

Density independent factors, in ecology, refer to any influences on a population's birth or death rates, regardless of the population density. Density independent factors are typically a physical factor of the environment, unrelated to the size of the population in question.

A population of a country can be controlled by war. During the war, there's a high death rate and low birth rate which decreases the population drastically, however post war there will be low death rate and high birth rate which increases the population.

Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration..

Population growth rate is affected by birth rates, death rates, immigration, and emigration.

Such an increase owes to two factors: the real interest rate paid by your investment account, and the overall rate of inflation. When you combine those two factors, you get what's known as the nominal interest rate.

Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration. ... Limiting factors determine the carrying capacity of a population. Recall that when there are no limiting factors, the population grows exponentially.

In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.

Population growth rate is affected by birth rates, death rates, immigration, and emigration.

A limiting factor is any factor that places an upper limit on the size of a population. Limiting factors may be biotic, such as the availability of food, or abiotic, such as access to water. ... Abiotic factors such as temperature, light, and soil can influence a species' ability to survive.

The two factors that affect the rate of weathering are the rock's type and the climate. If a rock is permeable, it weathers easily. The mineral content of the rocks influence how fast it would weather. There are minerals which dissolve easily in particular substances.

The two main flow factors in sediment transport are the settling rate and the boundary layer shear stress 27.

An organism's phenotype results from two basic factors: the expression of an organism's genetic code, or its genotype, and the influence of environmental factors. Both factors may interact, further affecting phenotype.

Several factors encourage, prevent, or limit the growth of microorganisms in foods, the most important are aw, pH, and temperature..

Physical factors that affect microbial growth? Temperature, ultraviolet radiation, and osmotic pressure. Some point between the minimum and maximum temperature. Enzymatic functions of bacteria are at their maximum rate, and growth occurs fastest at this temperature.

Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

There are four primary factors that affect plant growth: light, water, temperature and nutrients.

These four elements affect the plant's growth hormones, making the plant grow more quickly or more slowly.

Changing any of the four can cause the plant stress which stunts or changes growth, or improves growth..

Answer: There are two main factors which affect the density of water, namely, Temperature and Purity.

The two main factors that affect viscosity are temperature and silica content.

Factors That Affect the Rate of Dissolving A: The rate of dissolving is influenced by several factors, including stirring, temperature of solvent, and size of solute particles.

There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.

Density-dependant factors may influence the size of the population by changes in reproduction or survival. ... This in turn led to a decrease in per capita birth rate, a limitation in population growth as a function of population density. Density dependant factors may also affect population mortality and migration.

Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.

Environmental factors do affect a population's growth rate, however. The interaction of the population's natural growth rate and the environment determines the density of the surviving population. The maximum number of individuals that a given environment can support is called the carrying capacity.

The size of the human population, its concentration in particular places, and its pattern of growth are influenced by the physical setting and by many aspects of culture: economics, politics, technology, history, and religion.

Population Growth Rate The two main factors affecting population growth are the birth rate (b) and death rate (d). Population growth may also be affected by people coming into the population from somewhere else (immigration, i) or leaving the population for another area (emigration, e).

Our results suggest that gross national income (GNI); female primary completion rate; agriculture; growth of rural population; and governance indicators, such as political stability, control of corruption, or regulatory quality are variables related to water access, although specific associations depend on the source ....

Population growth rate is affected by birth rates, death rates, immigration, and emigration.

Newton's law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them. Objects with greater mass have a stronger force of gravity between them.

They found that a 1.2% rate of population increase leads to an average of 7 years of schooling while a 3.7% rate of population in- crease leads to an average of 3.7 years of school- ing.

The strength of the force of friction depends on two factors; the type of surfaces involves and how hard the surfaces push together, What is one way you could reduce the friction between two surfaces? Ball bearing are one way of reducing friction between two surfaces.

Exponential growth assumes that environmental factors like food, water supply, space, shelter, disease organisms, predators, weather conditions, and natural disasters do not affect the birth or death rate. As long as birth rate exceeds death rate (even slightly) population size will increase exponentially.

Limiting factors are resources or other factors in the environment that can lower the population growth rate. ... Limiting factors can lower birth rates, increase death rates, or lead to emigration. When organisms face limiting factors, they show logistic growth (S-shaped curve, curve B: Figure below).

Natality, mortality, immigration, and emigration rates apply to every population, including the human population.

The sum of these rates makes up the growth rate of a population..

Population growth rate is affected by birth rates, death rates, immigration, and emigration. If a population is given unlimited amounts of food, moisture, and oxygen, and other environmental factors, it will show exponential growth.

What two factors affect your personal appearance? Your health/physical body, and your clothing.

Demographics can include any statistical factors that influence population growth or decline, but several parameters are particularly important: population size, density, age structure, fecundity (birth rates), mortality (death rates), and sex ratio (Dodge 2006). We introduce each of these in turn.
