What else can I help you with?
What statement about microevolution and macroevolution is true?
Described by the definition for evolution. Evolution is the change in allele frequency over time in a population of organisms.The prefered terms are evolution ( instead of microevolution ) and speciation ( instead of macroevolution ).
Species drift to form a new species?
I think you mean genetic drift. Genetic drift is not strong enough in itself to cause speciation generally. Genetic drift is merely a sampling error in allele frequency change due to random events.
What is a process through which new species can arise?
Natural selection that leads to a great enough change in allele frequency over time in a population of organisms, evolution, and helped by environmental changes to create sub-populations of these organisms that can no longer breed among themselves and then are accounted new species.
How does the theory of evolution account for a new species?
Evolution explains changes in allele frequencies over time. As these changes in allele frequencies build up over time, a population can no longer be considered to be the same species it once was. Depending on generation lengths, these changes can take days or millions of years. When these times lengths are extremely long, it is hard to determine when exactly you would say one example is species A while another is species B; however, we have observed speciation (put "observed instances of speciation" into google) and have many other evidences that speciation occurs. For example, ERVs, biogeographical distribution of species, computational genomics and proteomics, vestigial genes and structures, ring species, and more.
How can genetic mutations support macro-evolution?
Mutations in an individuals germ line can be passed into progeny and if these mutations are beneficial then the allele frequency in the individuals population can change which is evolution. Over time and with many beneficial mutations against a favorable environment a population, or populations, most often geographically isolated, can change alleles so much that the two split populations can no longer interbreed and you have a new species; macro-evolution.
How does the frequency of a wave change as its wave length changes?
You can see how the frequency of a wave changes as its wavelength changes by using the formula Velocity= wavelength x frequencyIf for example we are talking about the speed of light (Which does change) and the wavelength is reduced, then the frequency has to increase in order to balance out to the speed of light.Another way to view it is like this:The frequency of a wave changes with the wavelength by what happens to the wavelength. For instance, if the wavelength is doubled, the frequency is halved, and vise versa.
Does an increase in wavelength result in higher frequency?
no, as the wavelengths become longer, they also become less frequent.the longer the wavelength, the lower the frequency. the shorter the wavelength, the higher the frequency===========================The product of (wavelength) x (frequency) never changes. So if either one changes,then the other one must change in exactly the opposite direction, in order to keeptheir product constant.(That product is the speed of the wave.)
What happens to the frequency as the electromagnetic wave gets longer?
the frequency reduces in value. The longer the wavelength the lower the frequency.
What statement about microevolution and macroevolution is true?
Described by the definition for evolution. Evolution is the change in allele frequency over time in a population of organisms.The prefered terms are evolution ( instead of microevolution ) and speciation ( instead of macroevolution ).
What is genetic drift and when might it occur?
Genetic drift is a random change in the frequency of alleles in a population over generations. It occurs in small populations where chance events can lead to certain alleles becoming more or less common simply due to random sampling.
In what way does varying the length of a string change the vibration?
Varying the length of a string changes its vibration frequency. A shorter string vibrates at a higher frequency while a longer string vibrates at a lower frequency. This relationship is described by the formula: frequency is inversely proportional to the length of the string.
Species drift to form a new species?
I think you mean genetic drift. Genetic drift is not strong enough in itself to cause speciation generally. Genetic drift is merely a sampling error in allele frequency change due to random events.
Do changes in the size of plants population have an effect on humans?
Yes, the more plants, the longer it takes to plant your garden.
Will a wavelength be shorter or longer the slower the object vibrates?
The wavelength will be longer if the object vibrates slower. Wavelength is inversely proportional to frequency; as frequency decreases, wavelength increases.
What is a process through which new species can arise?
Natural selection that leads to a great enough change in allele frequency over time in a population of organisms, evolution, and helped by environmental changes to create sub-populations of these organisms that can no longer breed among themselves and then are accounted new species.
Does longer wavelength mean higher frequency?
No. Longer wavelength means lower frequency.When you multiply wavelength by frequency, the product is always the same.
What frequency has a longer wave length 550KZ 152MHz 800MHz?
a frequency is inversely proportional related to the wavelength meaning that a higher frequency has a shorter wavelength. Therefore, the signal of 550 KHz has the longest wavelength.
