Answer:
The scientist should observe the species in the environment to determine the types of interactions that the two species have. Then, the scientist should transplant each species alone to a new area and simultaneously transplant both species together to see if the single-species transplants die
Explanation:
When two species are obligate mutualists, both species benefit one another in such a way that one cannot survive without the other. Hence, in order to find out if two species are indeed obligate mutualists, they should be transplanted together away from other species on one side, and also transplanted individually on another side.<em> </em>
<em>If they are obligate mutualists, the individual transplant would find it difficult to survive and should die in no time while the transplant done together should survive. All other factors being kept constant. </em>
Answer:
The indigenous groups of individuals in distinct parts of the world possess different skin colors from other groups of individuals. Following are the different kinds of evidence, which supports the idea:
1. The individuals would have moved around the globe, however, they would have still kept their skin color DNA.
2. There also would have been more individuals living all over the globe and the skin color of the individuals would have changed gradually with time.
3. Living at higher altitudes would have resulted in more variation as the amount of exposure would have been different from the individuals moving around the world.
The answer is : They are distantly related so their development is similar. They have different genetic materials.
The most logic answer is B.
