The correct answer is: If generation 3 had flock distributions similar to those shown in the graph below.
After the change in food, the beak phenotype changes in order to adapt. So, if fruit is removed, the phenotype of birds’ beaks should change according to the change in environment. The graph below shows that there is no change, so it wouldn’t support the hypothesis that food changes beak types.
I’m not an expert but I’d say B
A.)Well–developed vascular system
Vascular plants help maintain the water cycle. The property of these plants
enables them to carry out this function is their well-developed vascular system.
These type of plants are more evolved and developed than nonvascular plants
because of its specialized characteristics like xylem, which is a tissue that
is responsible for its framework and not only that, it is also has a greater mechanism
for water transference. Another is phloem, which is responsible for food
conduction.
