Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Some students are observing the behavior of a male bird in the schoolyard. Which of the following behaviors might increase the probability of reproductive success?
A
Made a chirping sound
B
Hopped along a tree branch
C
Flew from a tree to the ground
D
Flew away when a cat appeared
Explanation: 

Detailed explanation-1: -When a male is calling for a female bird it makes a special sound ( chirping sound ) to attract its mate within the vicinity and that way the probability of a reproductive success will increase.

Detailed explanation-2: -Examples of animal behaviors that affect the probability of plant reproduction could include transferring pollen or seeds, and creating conditions for seed germination and growth.

Detailed explanation-3: -Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. In many instances, the embryo is isolated within the female, which limits predation on the young. Internal fertilization also increases the likelihood of fertilization by a specific male.

Detailed explanation-4: -To increase the probability of successful reproduction, there are specialized plant structures such as brightly colored petals to attract potential pollinators and extended stamens that require animals to brush against the plants in order to receive the nectar.
