Behavior is the capacity of an organism to learn through experience. Behavioral ecology is study of how natural selection shapes the behavior of an organism. Behavioral traits are influenced by an organism’s environment. Some environmentally-induced variations in behavior occur due to epigenetic effects.

Summary Introduction

Concept introduction: Behavior is the capacity of an organism to learn through experience. Behavioral ecology is study of how natural selection shapes the behavior of an organism. Behavioral traits are influenced by an organism’s environment. Some environmentally-induced variations in behavior occur due to epigenetic effects.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer: Genes affect the behavior of individuals by influencing the development of nervous system, affecting the kinds of hormones in individuals, and determining which stimuli can be detected. Option d. is given as “all of the above”. Hence, option d. is the correct answer.

Explanation of Solution

Reason for the correct statement:

Studies of behavioral differences within a species or among related species can shed light on the proximate causes of a behavior and the ultimate causes that favored the behavior.

Option d. is given as “all of the above”. Behavior starts with genes that influence the development and the activity of the nervous and endocrine systems. Behavior is often a triggered response to a stimulus. This also affects the hormones in the individuals. Hence, option d. is the correct answer.

Reasons for the incorrect statements:

Option a. is given as “influencing the development of nervous system”. This is not the only factor that is affected by the genes. Hence, option a. is incorrect.

Option b. is given as “affecting the kinds of hormones in individuals”. This is not the only factor that is affected by the genes. Hence, option b. is incorrect.

Option c. is given as “determining the stimuli can be detected.” This is not the only factor that is affected by the genes. Hence, option c. is incorrect.

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

Conclusion

Genes affect the behavior of individuals by various factors such as influencing the development of nervous system, affecting the kinds of hormones in individuals, and determining which stimuli can be detected.

The metabolic pathway below is used for the production of the purine nucleotides adenosine monophosphate (AMP) and guanosine monophosphate (GMP) in eukaryotic cells. Assume each arrow represents a reaction catalyzed by a different enzyme. Using the principles of feedback inhibition, propose a regulatory scheme for this pathway that ensures an adequate supply of both AMP and GMP, and prevents the buildup of Intermediates A through G when supplies of both AMP and GMP are adequate.
