I’m not sure this is right but it might be stemcells ?
Hope this helped and sorry if it’s wrong !!
Answer:
Because they had to make sure the results were consistent.
Explanation:
Answer:
Animals breath out carbon dioxide, plants turn the carbon dioxide into carbon and release fresh oxygen as a result. The carbon goes through the rest of the carbon cycle.
Explanation:
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>
Their reproductive isolation from each other is complete: False
They are unable to produce hybrid offspring upon interbreeding: True
They shared a common ancestor recently in evolutionary time: False
Explanation:
A species known as a group of that organisms which can be potentially interbreed with another one to produce viable, fertile offspring. Prezygotic and postzygotic barriers separated the species from each other. It prevents the mating of viable fertile offspring.
This process happens when groups in that species become reproductively diverge as well as isolated. In the formation of new species postzygotic and Prezygotic barriers play vital role.
