Chapter 45, Problem 14PIAT
Summary Introduction
To analyze:
The conclusion that can be drawn from the data given in the question.
Introduction:
The muscle fibers are of three types: slow, fast, and intermediate. In the given experiment, the muscle fibers were categorized as fast and slow muscle fibers only. The absence of the intermediate muscle fibers during the time of the experiment was assumed. In an experiment given below, the biopsies of the gastrocnemius of 14 elite distance runners, 18 trained but nonelite runners, and 19 untrained subjects were obtained. Gastrocnemius is a muscle that forms the major bulk at the calf region present at the back of lower leg. A relationship was established between the muscle-fiber type and their performance, which is shown in the diagram below:

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.

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
