Natural Selection and Cell Signaling answers

what assumption is made when using the hardy weinnburg equation for calculating changes in allele frequency in a population

the population size is large

what is an outcome of natural selection

evolution

dogs are descended from the grey wolf by selective breeding and are thought to be first domesticated 30,000 years ago. what is the result of this selective breeding

dogs have a variety of phenotypes

how does overuse of antibiotics make them less effective

it increases the number of bacteria better adapted for survival

what is a result of natural selection

a decrease in the frequency of certain characteristics

what is the reason antibiotics are not used to treat the strains of viruses that cause influenza

viruses lack metabolism

which statement best describes how evolution occurs

natural selection decreases the frequency of unfavorable characteristics

what can be deduced from this graph

bacteria with beneficial adaptations survive and pass on their genes

what effect does this have on the evolution of antibiotic resistance in these strains of S. aureus

slower evolution, as the antibiotic bacteria resistance gene from other species will not be accepted

what is the name of the process that was used to produce modern corn

selective breeding

which factors would favour evolution by natural selection

variation within a species

which process results in decreased variation

natural selection

natural selection can operate in different ways. what is the effect of disruptive selection?

it eliminates individuals with intermediate forms of a characteristic

which is an example of natural selection

development of antibiotic resistance in bacteria

what is required for natural selection to occur

advantageous characteristics, genetic variation

what activates a tyrosine kinase pathway in a cell following binding to a receptor

insulin
