Sometimes unique habitats are home to threatened or endangered species. endangered means a particular animal or plant is sufficiently rare that it could easily disappear from indiana. threatened means it is likely to become endangered in the near future. in extreme cases it is possible the animal or plant is so rare it could disappear entirely and become extinct if its numbers become any smaller. the piping plover is an endangered species that can be found on the beaches along shorelines of the great lakes. all but one might be a method to protect the piping plover. a)continue water level manipulation along the major rivers. b)avoid bringing non-native or exotic species into the area. c)limit future commercial, residential, and recreational developments on the coast. d)prohibit people from bringing dogs to the beach where plovers are known to nest and breed.

The diagram below represents a marine food web and a process that can harm the human population. each circle represents an organism and the smaller dots inside them represent a toxic substance. what is being represented and how does it harm the population? the diagram represents biological half-life, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents the process by which different organisms prey upon each other; this can impact the human population by reducing the number of organisms that do not contain the toxin. the diagram represents the way that toxins are metabolized by living organisms, with those at greater trophic levels able to metabolize more efficiently than those at lower levels. this means that those at higher tropic levels are safer for humans to consume compared to the organisms at lower trophic levels.

Many farmers prefer cattle without horns because it is safer for their herds. the allele for no horns (n) is dominant to the allele for the presence of horns (n). a farmer mates a male with horns to a heterozygous female without horns. what is the chance that the offspring will have horns?
