Question

1. which scenario represents allopatric speciation?

a. two bird populations with different mating calls in neighboring areas
b. two fish groups living in shallow and deep waters of a river
c. plants preferring different pollinators within the same area
d. a group of rodents isolated on an island due to a geographic barrier

1. what is the primary goal of conservation?

a. increase human population growth
b. maximize economic gains
c. preserve biodiversity and preventing extinction
d. promote habitat destruction

1. which is an example of a conservation strategy for endangered species?

a. implementing captive breeding programs
b. introducing invasive species deliberately
c. encouraging habitat destruction
d. promoting overexploitation

Explanation:

1. Allopatric speciation occurs when a population is separated by a geographic barrier. In option d, rodents isolated on an island due to a geographic barrier represent allopatric speciation. Options a and c are examples of sympatric speciation - reproductive isolation within the same area. Option b is a habitat - related separation but not a strong enough geographic barrier for allopatric speciation.
2. The primary goal of conservation is to preserve biodiversity and prevent the extinction of species. Options a, b, and d are contrary to the concept of conservation.
3. Captive - breeding programs are a common conservation strategy for endangered species. Options b, c, and d are harmful to endangered species and go against conservation efforts.

Answer:

1. d. A group of rodents isolated on an island due to a geographic barrier
2. c. Preserve biodiversity and preventing extinction
3. a. Implementing captive breeding programs
