Why is variation beneficial to a population that is undergoing change?

Yes, it is. If there is variation in a populations, and a sudden catastrophic event occurs, there is more of a chance that some of the individuals in the population will survive, and the population will not die out.

What question did hardy and Weinberg want an answer?
Hardy and Weinberg wanted to answer the question of how genetic variation is maintained in a population over time. They developed the Hardy-Weinberg equilibrium principle, which describes the expected frequencies of alleles in a population that is not undergoing any evolutionary changes.
Do you think evolution on Earth has stopped?
Yes. Anytime a population is undergoing change of allelic frequencies, evolution is occurring.
How do mutations relate to natural selection?
Mutation, a copying error in the replication of DNA, can give rise to variation in an organisms phenotype and if this new phenotype is beneficial to survival and reproductive success ( as little as 1% ) it will be selected naturally against the immediate environment, then if this so selected organism leave many descendents with the same beneficial traits then the populations gene pool will change in allele frequency and you have evolution. ( a 19th century sentence Darwin would be proud of! )
How does mutation affect variation in species?
mutation really doesnt effect a population a mutation can be bad or good mutations can protect you from diseases or it can do something harmful to you like give u a extra body part or make you more vulnerable to diseases
When a substance is undergoing a chance of state the temperature of the substance does not change until the?
change is complete

How is genetic variation related to species chances of becoming extinct?
Little or no variation could lead to failure to adapt to changing conditions. Too much variation would prevent the species from passing on beneficial traits because they would change too rapidly.
How is genetic variation related to a species's chances of becoming extinct?
Little or no variation could lead to failure to adapt to changing conditions. Too much variation would prevent the species from passing on beneficial traits because they would change too rapidly.
Why are mutations importasnt to the modern theory of evolution?
Without beneficial mutations leading to beneficial variation there would be no natural selection on the individual organism, outside of sexual recombination, which would mean no change in allele frequency over time leading to no evolution. Fortunately, that is never the case in nature and mutations lead to variation and adaptive change in the organisms under selection pressure.
Why is it important that variation exists within populations of a species?
Without variation there is nothing to select for against the background of an immediate environment and thus no evolution as alleles, not selected for, would not change over time in this population of organisms. Without variation the environment can change quickly and send your population to extinction if there were no variants that could meet this challenge.

What is the difference between mutation and variation?
variation is difference between genes and trait among individual* organism within population. mutation is change in genetic instruction I hope it helps
What role do mutations play in evolution?
They provide the variation in organisms that other recombination methods do not. A beneficial mutation, leading to a small change in same trait, that is even marginally reproductively successful to the organism that possesses it will be selected for and passed on tho progeny thus changing the organisms population over time, regardless of how small the change. This is evolution, change in populations over time.

How do gene frequencies change when there is no relationship between genetic variation and reproductive success?
Alleles that are neither selected for or against will remain at the same frequency in a population. (This assumes that the population is also large enough to not suffer from variation due to genetic drift.)
What is the difference between absolute variation and relative variation?
relative change is a proprotional change where absolute change is a complete change.........
