Question

What is a natural selection? (1 point)
The creation of new genetic material.
The random change in allele frequencies in a population.
The movement of alleles between populations.
A process by which organisms with preferred traits are more likely to survive and reproduce.
Which of the following represents the difference between intraspecific competition and
interspecific competition? (1 point)
Intraspecific competition occurs between individuals of the same species, while interspecific
competition occurs between individuals of different species.
Intraspecific competition is always beneficial, while interspecific competition is always detrimental.
Intraspecific competition reduces the availability of resources, while interspecific competition
increases the availability of resources.
Intraspecific competition affects the population of a different species, while interspecific competition
affects the population of the same species.
Two populations of frogs living in the same pond but breeding at different times of the year is an
example of which type of reproductive isolation? (1 point)
Temporal isolation
Habitat isolation
Behavioral isolation
Geographic isolation

Answer 1

1. The correct definition of natural selection is: **A process by which organisms with preferred traits are more likely to survive and reproduce.**

2. The difference between intraspecific competition and interspecific competition is represented by: **Intraspecific competition occurs between individuals of the same species, while interspecific competition occurs between individuals of different species.**

3. Two populations of frogs living in the same pond but breeding at different times of the year is an example of: **Temporal isolation.**
