A newly discovered structure in a marine invertebrate is a gland, which is able to release hormone or hormones. Introduction: Generally, all the animal phyla consist of hormone systems secreting hormone released into the bloodstream to target distant organs to regulate specific physiological function. It is always important to know the true function of a structure present in an organism. When a new structure is discovered, which has not been studied before, there are studies done to know its true nature. To know that it is a gland secreting a hormone, experimental studies can be done to validate the hypothesis.

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
