In order for speciation to occur, population within a species must be isolated by their reproductive systems, to produce an organism completely different from what they started out with.
Answer:
Yes
Explanation:
Humans are good at it transferring energy from place to place.
Answer:
A good model organism should be able to be easily maintain in the laboratory, be fast growing, with a fast generation time and be as closely related to humans as possible.
Explanation:
The attributes that should be looked for in the selection of good model organism for investigating the impact of toxins in humans include:
- Easy maintenance: The easier the maintenance of the organism, the better for both the research and the researcher. More can be achieved with less effort as opposed to high maintenance animals.
- Fast generation time: They should be able to grow and reproduce quickly so as not to prolong the experiment for too long. The lower the regeneration time, the shorter the time required to obtain adequate data for the research.
- Genetical similarity to humans: A good model organism for humans related study must share some similarities with humans at the genetic level. The more the genetic similarity, the more applicable the outcome of the research on humans.
<em>Hence, a good model organism should be able to be easily maintained in the laboratory, be fast-growing with a fast generation time, and be as closely related to humans as possible.</em>
