The mode of nutrition in sponges. Concept introduction : All sponges belong to a phylum called porifera. They are simplest animal with cellular level of organization. They have diverged from other animals early in the evolution. Hence, they are called as basal animals. They have a very simple body structure composed of only two layers of cells. In between the two layers, a gelatinous region is present called mesohyl. The exchange of nutrient and waste material take place through diffusion in sponges.

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.
