B. a specific place on a chromosome where a particular gene resides.

A locus (plural loci) in genetics is the position of a gene on a chromosome. Each chromosome carries many genes; humans' estimated 'haploid' protein coding genes are 19,000-20,000, on the 23 different chromosomes. A variant of the similar DNA sequence located at a given locus is called an allele.

zalisa [80]

The correct answer should be D.) Declines in poisonous, non-edible mushroom species in cool climates. Although question B does provide evidence that Global warming could be the cause of the declines, it still doesn't disprove the theory that overharvesting could be the cause as well. Question C could be caused by a number of things, such as deforestation, a local change in climate, removal of agricultural pests, ect. Question A supports the hypothesis that overharvesting is the cause of the decline, instead of disproving it. Hope this helped!
