How does natural selection affect variation?
Variation naturally occurs in populations as new traits arise from random mutations. However, through natural selection only those traits that are beneficial to the organism are passed on to the next generation. Any harmful mutations are naturally weeded out.
Why are vestigial structures not removed by natural selection?
Nature selects against only harmful traits
How does natural selection produce adaptaions in a species?
Variant traits that increase the number of offspring become common in a population, causing the overal morphology and behaviour of the population to continuously shift to give the best reproductive chances for any given environment.
Is heater harmful or blower?
Neither should be harmful.
What are the Two harmful things the answer?
Two things that are harmful
Does natural selection lead to helpful or harmful variations that continue through the species?

How does population change as a result of natural selection?
Natural selection is not a thing that acts on populations, it is a tendency for harmful genes to not be passed on (die out) and useful variations to thrive and become common.

Which is a process that eliments harmful alleles from a gene pool?
natural selection
What is a process that eliminated harmful allele from a gene pool?
negative selection.
What is a process that eliminate harmful alleles from a gene pool?
negative selection.
Why does selection act faster against a harmful dominant allele than a harmful recessive allele?
The harmful dominat allele has a better chance of eliminating a population.
Why would there be a environmental problem if the gas from a reaction were allowed to escape into the atmosphere?
This is because gases that evolve o.whenthis happens also oxygen content inthe various spheres will gradually fade offut of chem reactions are highly concentrated and poisonous as well as harmful so when allowed to accumulate it will lead mendels law of survival of the fittest
What is a process the eliminates harmful alleles from a gene pool?
negative selection
why are structures not removed by natural selection?
Vestigial structures do not harm the organism. Nature selects against only harmful traits.
Why is it important to disinfect cleaning equipment such as squeegees?
Harmful bacteria can accumulate on anything used to clean with (sponges may be the worst). If they aren't disinfected, you will just spread the bacteria when you use the equipment.
The process that encourages the passage of benficial genes and discourages the passage of harmful or unfavorable genes from one generation to the next?
Natural selection.
