To compare: The problems posed by swimming and flying and how the animals overcome those problems. Introduction: Swimming is an activity that is carried out in water. As the water provides ample buoyancy, the problem of gravity is not faced. The drag that the water puts on the organism is a cause of problem for the organism. Flying is an activity that is carried out in air. The major problem faced during flying is that gravitational pull prevents the organism to fly. Since air is a reasonably lighter medium, so the issue of friction is not observed.

Summary Introduction

To compare:

The problems posed by swimming and flying and how the animals overcome those problems.

Introduction:

Swimming is an activity that is carried out in water. As the water provides ample buoyancy, the problem of gravity is not faced. The drag that the water puts on the organism is a cause of problem for the organism.

Flying is an activity that is carried out in air. The major problem faced during flying is that gravitational pull prevents the organism to fly. Since air is a reasonably lighter medium, so the issue of friction is not observed.

1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple different routes of administration provides greater insight than just 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: (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 po bioavailability, (f)Fpo absolute ip bioavailability, Fip MAKE SURE ANSWERS HAVE UNITS if appropriate. SHOW ALL WORK, including equation used, variables used and each step to your solution.

2. Drug quantification from plasma is commonly performed by using techniques such as HPLC or LC/MS. However, these methods do have limitations, and investigators may choose to use a radiolabeled analog of a drug instead. Radioligands are molecules that contain radioactive isotopes, commonly 3H or 14C. This technique allows investigators to quantify drug concentration from radiation measurements. The following measurements were made in 250 g rats following oral administration of 18.2 µCi of a 14C-labeled drug of interest: Time (min) Plasma Radiation Levels (µCi/L) 0 0.0 2 9.7 4 19.2 7 25.3 9 37.8 12 39.6 14 45.8 17 48.8 20 52.0 25 56.4 30 59.2 35 60.1 40 61.1 45 62.1 50 62.8 60 63.1 70 62.1 80 60.1 90 57.3 100 55.5 110 53.7 120 52.2 150 48.0 180 45.0 240 39.0 Note that a µCi is a measure of the amount of radioactivity and hence is a measure of the amount of drug present. Given that the oral bioavailability of this drug is known to be essentially 100%, estimate the following from this…
