2 4 5
Explanation:
or b d e evolution is not an individual occurrence
Question number 1.
The correct answer is: The insects are the same species.
There is still a lot of discussion in the scientific community on how should we define a biological species, but one of the main points that all scientists agree on is that the members of the same biological species are individuals that can successfully reproduce and leave viable and fertile offspring.
Question number two
The correct answer is : The graph showing directional natural selection.
In the case of the fish species of the coral reef, there are two extremes of the phenotype the dark orange and the pale one.
Before the bleaching of the coral, the dark orange phenotype was better adapted to the environment. But after the bleaching of the coral, the pale phenotype now resembles the coral background more and it is able to hide from the predators better than the dark orange one.
This will result in natural selection favoring the pale phenotype more and working in the direction of this extreme on the graph.
