The northern red-legged frog, or Rana aurora, is found along the western coast from British Columbia to Northern California. The
ir typical breeding season lasts from January to March. The foothill yellow-legged frog, or Rana boylii, is found along the western coast from northern Oregon to central California. Their typical breeding season lasts from April to July. What mechanism might keep Rana aurora and Rana boylii from mating? A) anatomical isolation
B) temporal isolation
C) geographic isolation
D) behavioral isolation
<span> <span>Temporal isolation is a type of reproductive isolation, which could be prezygotic or postzygotic. Temporal isolation is prezygotic reproductive isolation since it occurs before fertilization and zygote production. Temporal isolation is result of temporal differences in breeding. In this example, the breeding season of Rana aurora lasts from January to March while the breeding season of Rana boylii lasts from April to July. So, these two breeding seasons do not coincide and these species could not mate.</span></span>
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

A disaccharide is formed by two monosaccharides through a condensation reaction. The Hydrogen of one of monosaccharide pairs with the hydroxide (OH) of another monosaccharide. Whe this happens H2O is formed The water molecule is then removed leaving the functional groups of the two monosaccharides able to bond with each other.
None. There's no such thing as "short term climate change". By definition, climate change is a long term. Short term changes are "weather", which has a great many causes. Hope this helps :)
