Consider the status of the black-footed ferret. what is the most logical contributing factor to its endangered status? a) the exponential growth of ferret predator populations. b) human encroachment that has greatly reduced the prairie dog populations. c) the growing habitat range of the prairie dog populations throughout the united states. eliminate d) climatic change that has significantly modified the climate of the central united states.

The most logical contributing factor for the endangered status of black-footed ferret is Human encroachment. Farmers and ranchers (with government assistance) eliminated many prairie dogs because their underground complexes were destructive to fields. This led to decrease in the prairie dog populations, the primary prey of black-footed ferret.

b) human encroachment that has greatly reduced the prairie dog populations

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
