The evolutionary processes which are likely to explain the observed evolutionary changes. The important and unimportant processes in the evolutionary change. Introduction: Anole is the largest and diverse group of lizards found in America. It is the most common organism for the ecological and evolutionary studies. The two species A. carolinensis (Anole) and the A. sagrei compete with each other and are aggressive. The species of anoles have a strong association of height and structure of toe pads, which the lizards use to climb. The researchers found that the habitat of the lizards affected the evolution in the lizards. When the A. sagrei was introduced on the islands the changes were observed. On the islands, which did not support the A. sagrei and only had A. carolinensis , no changes were observed. The researchers then collected the samples of each type and also raised an offspring of lizard in the controlled environment and they researched about the differences in the genetic basis.

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, Fpo

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.) (e)…
