What is the main way individual's leave a population?
Individuals can leave a population through either death or emigration. Death results in a permanent loss of individuals from the population, while emigration involves individuals moving out of the population to join another population or habitat.
What is a fixed allele.?
An allele present in all members of a population
In the Hardy Weinberg equation shown below P is the frequency of the dominant allele and q is the recessive allele?
Homozygous recessive genotype
Process where characteristics in a population change over time?
Evolution is the process by which the characteristics of a population change over time through the mechanism of natural selection, genetic drift, gene flow, and mutation. This results in the adaptation of species to their environments and the formation of new species.
Stabilizing selection results in more or less genetic diversity?
Stabilizing selection typically results in less genetic diversity because it selects against extreme phenotypes, narrowing the range of traits present in a population. This leads to the preservation of intermediate phenotypes that are favored by the selective pressures, reducing overall genetic variation.
How do change Genetic equilibrium lead to speciation?
Allele frequency is altered by genetic drift, natural selection, migration, mutation, or nonrandom mating. This results in a change in genetic equilibrium in a population that is evolving. Evolution leads eventually to speciation.
What is migration transition?
Change in the migration pattern in a society that results from industrialization, population growth, and other social and economic changes that also produce the demographic transition.
The size of a population can get larger with no influences from migration if birthrate or death rate .?
The size of a population can get larger with no influences from migration if birthrate is greater than the death rate. This results in a natural increase in population size due to more individuals being born than those dying.
Pitch corresponds to what characteristics of a sound wave?
Pitch corresponds to the frequency of a sound wave. A higher frequency results in a higher pitch, while a lower frequency results in a lower pitch.
What were the results of Hebrews migration?
all the jobs being taken
What is the main way individual's leave a population?
Individuals can leave a population through either death or emigration. Death results in a permanent loss of individuals from the population, while emigration involves individuals moving out of the population to join another population or habitat.
How do you work out stratified sampling?
If a sample of size s is to be taken from a population of size n, then every n/s member of the population is tested. The starting point is chosen at random.If we want to test a 100-strong sample from a population of 2000, we test every 2000/100 = every 20th member. We use random numbers to determine the starting point.
What must change in order for the pitch of a sound change?
The frequency of the sound wave must change in order to change the pitch of a sound. A higher frequency results in a higher pitch, while a lower frequency results in a lower pitch.
How do you choose carrier frequency value?
typically the carrier frequency has to be at least double the signal frequency but in order to get better results you want to choose a frequency that is at least 5 times the highest frequency you are designing for.
What is the main cause of urban migration in the US?
The main causes of urban migration in the United States is economics. Means of supporting oneself sometimes results in moving to where business is thriving.
What is frequency applied to sound waves?
Frequency applied to sound waves refers to the number of cycles or vibrations that occur within a specified time frame. It is measured in Hertz (Hz) and determines the pitch of the sound produced - higher frequency results in higher pitch, while lower frequency results in lower pitch.
The Doppler effect of a passing siren results from an apparent change in?
The Doppler effect of a passing siren results from an apparent change in frequency as the source of the sound moves relative to the observer. This change causes the pitch of the sound to either increase (higher frequency) as the source approaches or decrease (lower frequency) as the source moves away.
