A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa.
Wolves are large, predatory canids once common throughout North America, Europe, Africa and Asia, now living mostly in remote wilderness. They are the largest living members of the canid family, which also includes foxes and coyotes.Wolves are the ancestors of all domestic dogs.There are two species of wolves in North America. The smaller species is the red wolf, Canis rufus, which has shorter, redder fur than the gray wolf. The gray wolf, Canis lupus, has thicker fur which is more gray or golden, and is larger than the red wolf.olves are large, predatory canids once common throughout North America, Europe, Africa and Asia, now living mostly in remote wilderness.

A study of pig mtDNA sequences by Greger Larson and colleagues in Science establishes that domesticated pigs originated in multiple geographic locations from different ancient wild boar populations.hey also argue that the structure of the data exclude the alternative hypothesis, that European wild boars are largely derived from feral populations of pigs with origins elsewhere. Additional pigs from other regions appear to provide evidence of several other domestication events in other areas.
