The correct answer is speciation.
Speciation is the term that describes the evolutionary process causing populations to evolve into different species. There are four different types of speciation: allopatric, peripatric, parapatric and sympatric. In this case, the process described is an allopatric speciation, the most common of these four types. Allopatric speciation happens when populations are geographically separated, an event that obstructs the gene flow. Since the gene flow stops, the populations evolve in response to the different environments that they live in.
<span>This is continuous aerobic activity. While regular aerobic activity can incorporate rest periods, this style of activity does not. Activities such as walking, slow jogging, stair climbing, and swimming can all fit this definition, because they can be done without rest for long periods.</span>

This is so simple. Read your lesson. If you cheat like this you'll never get through the rest of the course.
Explanation:
Rainforest cover only 2 % of the total surface area of the Earth but in spite of that about 50 % of plants and animals that live on the Earth live there.
By definition rainforests are forests that recieve high amounts of rainfall so you can actually find rainforests in Alaska for example (other examples: Canada, Asia, Africa, Latin and South-America)
About 1/4 of natural medicines are found in rainforests. 70 % or more of the plants that are used to treat cancer are found only in tropical rainforest on the planet.
Trees in tropical rainforests are so dense that it takes approximately 10 min for the rainfall to reach the ground from canopy.
Answer:
Whales are mammals and do not have gills, so they cannot take the dissolved oxygen that is in the water and turn in into a oxygen that they can breath.
