Chapter 19, Problem 4DAA
Summary Introduction
To explain: The reason for the rise in CO2 at the far right of the graph.
Concept introduction: Carbon dioxide is a colorless gas that consists of a carbon atom, which is covalently double-bonded to two oxygen atoms. It is an important trace of the Earth’s atmosphere. The concentrations of the carbon dioxide and oxygen in the Earth’s atmosphere have varied during the early period to the present day.

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.

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?

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_forward
- 3. 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_forwardWhich single food item contained you ate for the 3 days with the most sodium?arrow_forward
