Question
Chapter 39, Problem 1SQ
Summary Introduction
Introduction:
The behavior of an individual animal can be determined by the genetic trait of an individual.
Expert Solution & Answer
Answer to Problem 1SQ
Correct answers:
Genes affect the behavior of individuals by the development of the nervous system, response towards a particular hormone and stimuli. Hence, the correct answer is option d.
Explanation of Solution
Reason for correct answers:
Option d. is given as “all of the above.”
Structure of the nervous system helps in detecting the particular types of stimuli and can modify the response of animals against that stimuli. Hormones work together with the nervous system and influence the behavior of an individual animal. Detection of particular stimuli by an individual animal can affect the genetic behavior of an animal.
Reason for incorrect answer:
Option a. is given as, “influencing the development of nervous systems.”
The nervous system, together with the hormonal system, determines the genetic behavior of an individual. Hence, option a. is incorrect.
Option b. is given as, “affecting how individuals respond to hormones.”
Hormones are the chemical messenger that affects the behavior of the individual. Nervous system and detection of particular stimuli also change the behavior of an individual. Hence, option b. is incorrect.
Option c. is given as. “determining which stimuli can be detected.”
Only a detection of particular stimuli alone cannot affect the genetic behavior of an individual. Hence, the option c. is incorrect.
Hence, the option a., b., and c. are incorrect.
Conclusion
Development of the nervous system, response towards a particular hormone and stimuli can affect the behavior of an individual animal. Thus, the correct option is d.

In a natural population of outbreeding plants, the variance of the total number
of seeds per plant is 16. From the natural population, 20 plants are taken into
the laboratory and developed into separate true-breeding lines by self-
fertilization-with selection for high, low, or medium number of seeds-for 10
generations. The average variance in the tenth generation in each of the 20 sets
is about equal and averages 5.8 across all the sets. Estimate the broad-sense
heritability for seed number in this population. (4 pts)

You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait?

- Kinetics: One-Compartment First-Order Absorption 1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple routes of administration provides greater insight than a single route of administration alone. The following data was collected in 250-g rats following bolus IV, oral (PO), and intraperitoneal (ip) administration. Using this data and set of graphs, determine:(calculate for each variable) (a) k, C0, V, and AUC* for the bolus iv data (b) k, ka, B1, and AUC* for the po data c) k, ka, B1, and AUC* for the ip data (d) relative bioavailability for po vs ip, Fpo/Fip (e)absolute ip bioavailability, Fip (f) absolute po bioavailability, Fpoarrow_forward3. A promising new drug is being evaluated in human trials. Based on preliminary human tests, this drug is most effective when plasma levels exceed 30 mg/L. Measurements from preliminary tests indicate the following human pharmacokinetic parameter values: t1/2,elim = 4.6hr, t1/2,abs = 0.34hr, VD = 0.29 L/kg, Foral = 72%. Based on these parameters, estimate the following if a 49 kg woman were to receive a 1000mg oral dose of this drug: (a) Estimate the plasma concentration of the drug at 1hr, 6 hr, and 20hr after taking the drug ( Concentration estimate) (b) Estimate the time for maximum plasma concentration (tmax). (c) Estimate the maximum plasma concentration (Cmax). (d) Estimate the time at which the plasma level first rises above 30 mg/L. (Note this is a trial and error problem where you must guess a time, plug it into the concentration equation, and determine if it is close to 30 mg/L. Hint: based on part (a) it should be apparent that the answer is less than 1hr.)

For instance, if you like to drink soda, you might substitute skim milk or water for some of the soft drinks you consumed. List the item you wish to replace with the new item and what you hope to accomplish with that substitution. Be sure to choose foods you know that you'd enjoy and you consider more "healthful." If you feel your diet is already balanced, describe how you accomplish your balanced intake and when you began eating this way.arrow_forward
