Answer:
Yes, it is a reasonable conclusion.
Explanation:
The long lasting gas that kept sunlight from penetrating the atmosphere was the key factor that promote a disturbance on the chain food. Without sunlight, plants could not produce their own energy, therefore they could not resist to this environment condition and die. That way, the herbivores could not feed and die as well. Also the carnivore could not survive because their supply of food of herbivores are not alive anymore. This scenario would promote a mass extinction of every dinosaur.
Answer:
The mutation will become more common in offspring and increase the genetic variability in the gene pool.
Explanation:
If the mutation is beneficial to the organism and this organism breeds its offspring may carry this gene, if it´s really beneficial and for example makes an organism to have more access to females the mutation may spread faster.
The only way for a mutation to spread to other organisms is reproduction (eukaryotes)
A mutation may also spread to other organisms in prokaryotes in which bacteria may take plasmids (DNA fragments) from the environment.
