Your teacher describes a population otwo insect groups vary genetically by two genes. when put together, they were able to reproduce and produce offspring that could also breed. which best describes this insect population? f fish that live in a coral reef. some fish are dark orange (the same color as the coral); other fish are nearly white. human activity has led to the bleaching of the coral reefs, making them very pale in color. over time, the population of fish will be affected. which graph represents the type of selection that you expect to occur? *the insects experienced geographic isolation.*the insects experienced reproductive isolation. *the insects are different species.*the insects are the same species.

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.

Ais the correct answer

Cbecause it is the only one describing a habitat
