Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The climate of a certain area is cold, and snow is found on the ground most of the year. Equal numbers of two populations of rabbits are introduced into this climate by a group of scientists. One of the populations is brown and the other is white. Predict what will happen over several generations.
A
There will be equal numbers of brown and white rabbits
B
There will be more brown rabbits that white rabbits
C
There will be more white rabbits than brown rabbits
D
There is no way to predict what will happen to the rabbit population
Explanation: 

Detailed explanation-1: -Overproduction happens when species reproduce many more offspring than can possibly survive. The world has limited resources. Many species create many more offspring than there are resources like food, water, and living space to support them. This creates a struggle to survive for the offspring.

Detailed explanation-2: -Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet’s history. They can also help scientists control the mosquito populations (and reduce malaria) in these regions.

Detailed explanation-3: -For speciation to occur, two new populations must be formed from one original population, and they must evolve in such a way that it becomes impossible for individuals from the two new populations to interbreed.

Detailed explanation-4: -Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population.
