The main difference between the two is perspective. For example, if someone who lived in Norway moved to France, they would have emigrated from Norway and immigrated to France. In history, here is an example of emigration: During the potato famine in Ireland between 1845 and 1849, roughly 1.5 million adults and children emigrated from Ireland ...
Explanation: Gene flow, or the transfer of genes from one population to another, occurs whenever an individual (or group) moves and encounters another individual and genes are exchanged. Gene flow happens when an immature animal leaves its natal group and joins a new group either permanently or for an extended period of time. Gene flow can also ...
The formula for population growth is below: Learn about Euler's number here or here. For example, if we have a population of zebras in 1990 that had 100 individuals, we know the population is growing at a rate of 5%, and we want to know what the population is in the year 2020, we would do the following to solve: =100*e^ (.05*30yrs) **note that ...
Overpopulation led heavy use of resources (including China). War, decrease of resources, pollution, conflicts, sanitary problems Overpopulation cause pollution. Mexico city, for example, is overpopulated and air pollution is an issue. Overpopulation cause traffic problems. When you wait longer with your car, you cause atmospheric pollution.
An explanation, walked through: The Hardy-Weinberg equilibrium is a mathematical relationship of the alleles and genotypes in a population that meets certain characteristics. The relationships are as follow: Alleles: p +q = 1. p = frequency of the dominant allele. q = frequency of the recessive allele. Genotypes: p2 + 2pq+ p2 = 1.
One of the main reason of Genetic drift is MIGRATION. - MIGRATION is simply the process of moving from one place to another. - This causes the removal of a particular type of allele from that particular place. - In terms of Genetic Drift it is defined as the isolation of a group of species ,or genes from one place to another which result in the huge loss of that species or genes from that ...
The sound of the gun is sensed by the ears and a message is sent by the central nervous system to the legs and arms. Muscles contract which allow the runner to explode out of the blocks. The sound of the gun is the stimulus, the athlete starting to run is the response. Video from: Noel Pauller. mrpauller.weebly.com · 6 · Sep 10 2015.
Answer link. He had a series of laws passed During Roosevelt's presidency the breaking up of corportations was made through the passing of many laws that weakened their hegemony. " When Roosevelt became president in 1901 he shifted the Republican Party to a more populist direction by increasing anti-trust prosecutions.
Explanation: Mitosis occurs in all somatic (body) cells. There are four phases of mitosis (PMAT) ~. During prophase, the chromosomes form, and the nuclear envelope and the nucleolus are no longer visible. During metaphase, the spindle fibers attach themselves to the centromeres and the chromosomes line up at the center of the cell.
Dirt and water. Pebbles and water. Cornflakes and milk. Answer link. You can use filtration to separate a mixture of a solid in a liquid or a solid in a gas. Filtration is a separation process in which a mixture is passed through a filter that allows one component to pass through uninhibited but blocks another component from passing through.
