what did lyell suggest in the renewal argument for uniformitarianism
natural process starts slow and steady , and the earth is less than 6000 years old
natural process are fast paste and the earth is younger than 6000
natural processes are slow and steady, that the earth is much older than 6000

what did the principle of population state
that food availability, war ,disease limits the size of human population
that food availablity, predators, natural disasters limit the size of human population
that food availability war, climate changes, disease limits the size of human population
the food availability disease, evolutional change , war limits human population
how did malthus provide insight that aristotle was wrong about “individuals in a population were the same species”
instead individual better able to obtain resources were more likely to survive
they do not obtain vital resources to live
over time environmental challenge will boost the more poorly equipped variants
gradually the population would remain the same

what does fitness refer to in species
an organisms contribution to the next generations gene pool
how the organism is in shape
organisms chance in survival
organisms adaption
what is a genotype frequency
number of individuals of one genotype divided by the number of individuals in a population
number of individuals of two or more genotypes multiply by the number of individuals in the population
the number of individuals of multiple genotypes divide by the number of individuals in the population
number of individuals of one genotype added by the number of individuals in the population
what is the hardy-weinberg equilibrium
situation in which allele frequency and genotype frequency do change from one generation to the next
situation in which allele frequency and genotype frequency do changes from one generation to the next
situation in which allele frequency and genotype frequency multiplied from one generation to the next
situation in which allele frequency and genotype frequency divide from one generation to the next
the hardy weinberg equilibrium only occurs in population that
natural selection does occur mutations do not occur, new allele,population isn’t large enough to estimate the change in alleles, non random mating, migrate
natural selection does not occur, mutations do not occur, no new alleles, population is large enough to estimate random changes in alleles, random mating, do not migrate

when does a population violate the assumption of hardy weinberg equilibrium
phenotypes are better adapted to environments than others, mutations introduce new alleles, allele frequency change due to chance, individual remains in closed groups, individuals migrate among populations
phenotypes are not better adapted to the environment than others, mutations does not introduce new alleles, allele frequency does not change due to chance, individual don’t remain in closed groups, individual don’t migrate among populations
phenotypes are better adapting to environment than same species, mutations introduce new allele, allele frequency changes due to chance, don’t remain in closed groups, individual migrate among populations
phenotypes are better adapted to environments than others, mutations does not introduce new alleles, allele frequency changes due to chance,don’t remain in closed groups, individuals migrate among populations
why doesn’t the hardy weinberg equilibrium happen in real population
in real population at least at least one of the requirements are broken
in the real population all of the requirements are met
in the real population only some of the requirements are met
in the real population none of the requirements are met
