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.
Answer:
Salt water I think. Mostly oceans right?
Explanation:
Answer: Option B
Pigs wallow in the mud to cool themselves down.
Explanation: Pigs' skin contains lots of fats, and fats serves as thermal insulator during cold (low temperatures); unfortunately, this feature turns becomes a disadvantage during heat (high temperatures). Hence, pigs frequently wallows in the mud (or any nearby cool water place) - to reduce their body temperature.
a atmospheric rock is the "answer" sorry just need some points
