1. Biologists can set up an ecosystem in a small, sealed aquarium that continues to function without maintenance for years. Describe the minimum biotic and abiotic components it must contain to remain balanced and stable.

Expert Solution & Answer

Summary Introduction

To determine:

The minimum abiotic and biotic components required to maintain a balanced and stable sealed aquarium for years.

Introduction:

To maintain a balanced and stable sealed aquarium, it has to act like an aquatic ecosystem. It should contain the adequate and required abiotic and biotic components. A sealed aquarium ay be thought of as a mini lake and hence a similar kind of ecosystem needs to be created.

Explanation of Solution

The concept of creating is a sealed aquarium is similar to making a nature aquarium. The major requirements are primary producers, consisting of phytoplankton, algae and diatoms. Consumers such as zooplanktons, small and large fishes are required and decomposer microbes are must. There should be appropriate amount of sunlight or artificial light that can help in photosynthesis along with supply of oxygen and carbon dioxide. An artificial bedrock also needs to be created.

Conclusion

Hence, it may be concluded that, an artificial sealed aquarium needs appropriate abiotic and biotic components.

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…
