Answer:
Toucans disperse seeds of key forest species such as juçara palms by eating the fruit and defecating the seeds in new locations, sometimes more than a kilometer away. If there are no toucans, is the genetic diversity of palms likely to increase or decrease within forest fragments (and why)?
The genetic diversity of palm will totally decrease as a result of absence of Toucans dispersal of palms seeds which would not allow the seeds to be randomly grown anywhere. Dispersal has great impact on biodiversity of fruits because it enables the distribution of seeds to be grown everywhere
Explanation:
d. Mutations
Mutations are a natural
phenomenon that are alterations or slight modifications that occurs in the DNA.
It actually is typical for these modifications to occur in most DNA in our chromosomes.
Though the changes both intrinsically and extrinsically can only be the result
of such need, insignificant or have an insidious effect. It can’t be avoided
and it usually happens every time cells undergoes mitosis and meiosis. Further,
most of these modifications in the copied cells are good. Lastly, the mutation
process happens in the basic structure that shapes every cell and every
creature so it just a natural phenomenon, mostly.
