Answer:
1. They indicate convergent evolution.
2. They indicate a very close evolutionary relationship.
Explanation:
Convergent evolution is when two species have similar traits that may have evolved at different times, or "independently." So that's a correct answer.
Having a close evolutionary relationship would be both evolving to fit a specific environment in a same way. Meaning that the same factor may have forced them to evolve the same.
It is true that once glucose, galactose, and fructose enter the absorptive cells, they are transported to the portal vein and then to the liver.

For the pheasant question, it would be the top right graph as this shows an increase, then a further increase in the population of pheasants.
For the population of the world graph, it shows positive exponential growth as it is a large amount of growth within a small time period
