Answer:
<em>Geographic isolation</em>
Explanation:
Geographic isolation can be described as a term that describes the model of speciation in which a biological population becomes isolated from other members of the population and can no longer have gene flow with them.
The same scenario of gene isolation is occurring in the species of taods which live at the top of the mountains in southern Arizona. This population has become reproductively isolated fro all other species of toads within the mountain range.
Answer – Unbearable Stress
The precipitating factor for a dissociative episode is
usually an unbearable stress. While heavy use of alcohol,
history of head trauma, epilepsy, and major depressive disorder (MDD) have all been associated with dissociative fugue, i<span>ts onset is usually associated
with a stressful life event.</span>
<span>The second step of protein synthesis is translation, which occurs in the cytoplasm and requires ribosomes. A small ribosomal subunit attaches to the bottom of the mRNA strand, and a large ribosomal subunit to the top of the mRNA. Then the synthesis can begin.</span>
Answer:
(A) While not important in the diet of raccoons or striped skunks, ground squirrels are a significant source of food for other waterfowl-nest predators.
Explanation:
According to the passage, some predators of waterfowl nests prey opportunistically on songbird nests. Therefore, some wildlife management procedures directed at waterfowl, such as habitat enhancement or restoration, may also benefit songbirds. However, some procedures such as predator control may not always lead to benefits for the songbirds. For example, some predators of waterfowl nests such as raccoon and striped skunks are not predators of small mammals such as mice and ground squirrels who themselves are predators of songbird nests. So removing the striped skunk and raccoons from the habitat of the waterfowl and songbird nests, may not bring any benefit whatsoever to the songbirds. However, many other predators of waterfowl nests are also predators of squirrels and mice.
