Answer: Option A
Explanation:
The hypothesis states that the lizards living in different regions belong to the different food preferences.
No, the hypothesis will be proved correct only when the lizards will be kept in the same condition then their food preferences will be studied.
If their food preference will still be the same then it can be concluded that they reflect parental food preferences.
Else, if they will feed on the food given to them then the hypothesis will be rejected.
Explanation:
Natural selection is the mechanism that is responsible for the evolution of organisms.
In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.
The <em>C. cantonensis </em>is brighter in color whereas the <em>C. multidentata</em> is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore <em>C. cantonensis</em> is more susceptible. The mottled drab species is not easily predated by the species.
The 30 % offsprings of <em>C. cantonensis</em> can survive till the reproductive age whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.
The species with mottled drab color is the result of the differential reproductive rate.
