Why the transplantation of tissue from an older embryo of a salamander to a frog tadpole does not form balancers in tadpole snouts, whereas when a young salamander embryo is transplanted, the tadpoles develop balancers. Introduction: The nuclei of early embryos have the capacity to give rise to an entire organism. These cells have the ability to develop into tissues by surrounding the cells as they are not committed, that is, determined. This is known as conditional development. The other type of development is autonomous development. Hypothesis: The cells of the embryo that are committed will form the structure accordingly, even if they are transplanted at an equivalent site.

According to a recent study, 1 out of 50,000 people will be diagnosed with cystic fibrosis. Cystic fibrosis can be caused by a mutant form of the CFTR gene (dominant gene symbol is F and mutant is f). A.

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
