What are two factors that affect population size?

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.

Current population size will affect future market demand through prices and supply elasticity. Population changes are slow, and consumption changes are slow. ... A large consumer population and a smaller supply elasticity result in high costs of installation, which are made higher by the state monopoly.

Supply and demand, company financial performance and broad economic trends are three factors that affect the market value of stocks.

Biotic and abiotic factors determine the population size of a species in an ecosystem. ... Biotic factors include the amount of food that is available to that species and the number of organisms that also use that food source.

The actual trends that are observed with atomic size have to do with three factors. These factors are: the number of protons in the nucleus (called the nuclear charge). the number of energy levels holding electrons and the number of electrons in the outer energy level.

Various factors that affect electron affinity are atomic size, nuclear charge and the symmetry of the electronic configuration. Atomic size: With increase in the atomic size, the distance between the nucleus and the incoming electron also increases.

These factors are: the number of protons in the nucleus (called the nuclear charge). the number of energy levels holding electrons and the number of electrons in the outer energy level.

The size, mass, and arrangement of atoms affect the density of a substance.

Pressure and temperature are the two factors that have the greatest affect on density. Mass and volume are the variables we measure to calculate density. Size and shape have no affect on density. Objects that are the same substance always have the same density, regardless of size and shape.

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.

Internal factors that can affect gene expression are hormones, metabolic products and gender.

The amount of memory, the width of its data path, and its access time.More items...

The housing market is influenced by the state of the economy, interest rates, real income and changes in the size of the population. As well as these demand-side factors, house prices will be determined by available supply.

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.

Physical factors that affect population density include water supply, climate, relief (shape of the land), vegetation, soils and availability of natural resources and energy.

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.

There are three main factors that affect the size of the atoms: the nuclear charge of the atom, the shielding effect, and the number of energy levels that hold the electrons.

The margin of error is affected by three factors: confidence level, sample size, and population standard deviation. You should understand how increasing or decreasing any of these factors will affect the margin of error.

Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure.

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.

The size of solute particles, stirring, and temperature, are the three factors that affect the solubility of a solid solute in a solvent.

Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core.

Factors affecting account inherent risk include:Dollar size of the account.Liquidity.Volume of transactions.Complexity of the transactions.New accounting pronouncements.Subjective estimates.

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.

As population size approaches the carrying capacity of the environment, the intensity of density-dependent factors increases. For example, competition for resources, predation, and rates of infection increase with population density and can eventually limit population size.

Carrying capacity is defined as the "maximum population size that an environment can sustain indefinitely." For most species, there are four variables that factor into calculating carrying capacity: food availability, water supply, living space, and environmental conditions..

Abiotic factors that influence aquatic biomes include light availability, depth, stratification, temperature, currents, and tides.

Briefly describe external factors that affect selective attention. External factors are related to the features of stimuli. Other things held constant, the size, intensity, and motion of stimuli appear to be important determinants of attention.

The main factors determining population distribution are : climate, landforms, topography, soil, energy and mineral resources, accessibility like distance from sea coast, natural harbours, navigable rivers or canals, cultural factors, political boundaries, controls on migration and trade, government policies, types of ....

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.

1. Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed.

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..
