Behavior is defined as “a predictable response to external stimuli.” Behavioral patterns displayed by animals can be either inborn (fixed) or learned. Fixed behaviors are displayed since birth and initiated in response to simple external stimuli. Learned behaviors are responses based on past experiences of the animal, and allows them behave flexibly to their surroundings.

Chapter 22, Problem 1SQ

Summary Introduction

Concept introduction: Behavior is defined as “a predictable response to external stimuli.” Behavioral patterns displayed by animals can be either inborn (fixed) or learned. Fixed behaviors are displayed since birth and initiated in response to simple external stimuli. Learned behaviors are responses based on past experiences of the animal, and allows them behave flexibly to their surroundings.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer: “Behavior enables animals to respond quickly to changes in their environment”. Therefore, option d. is correct answer.

Explanation of Solution

Reason for the correct statement:

Behavior enables animals to give responses like realizing the presence of predator in the niche, the change in seasons, climate so they migrate or hibernate accordingly, coordinate activities within their community like the bees and the wolves, to find food, water, and shelter and for parental care.

Option d. is given as “enables animals to respond quickly to changes in their environment”. As, “Behavior enables animals to respond quickly to changes in their environment”, option d. is the correct answer

Reasons for the incorrect statements:

Option a. is given as “is seen in vertebrates, but not in invertebrates”.

Behavior is observed in both vertebrates and invertebrates. So, option a. is incorrect.

Option b. is given as “always involves communication”.

Behavior does not involve communication alone. It involves finding basic survival needs like food, water and shelter and also adapt to changing environmental conditions. So option b. is incorrect.

Option c. is given as “enables animals to evolve”.

Behavior has no role in evolution. So, option c. is incorrect.

Hence, options a., b., and c. are incorrect.

Conclusion

Behavior enables animals to react rapidly to changing environment.

There is a species of eagle, which lives in a tropical forest in Brazil. The alula pattern of its wings is determined by a single autosomal gene with four alleles that exhibit an unknown hierarchy of dominance. Genetic testing shows that individuals 1-1, 11-4, 11-7, III-1, and III-4 are each homozygous. How many possible genotypes among checkered eagles in the population?
