Gas Exchange (4/2010) Basic metabolism of terrestrial organisms: plants take in CO2 and H2O and relseas CH2O and O2 which mammals take in and then give off CO2 and H2O Gas is exchanged though the opening of the stoma between two guard cells of the leaf epidermis.

Affinity chromatography technique is used to separate proteins found in a mixture of solution. Affinity chromatography uses the strong interaction between a given protein and its corresponding molecule. In today’s lab‚ affinity chromatography was used to purify L-lactate dehydrogenase‚ which contains histidine-tagged protein. The histidine- tagged protein forms a strong interaction with the Ni-NTA column due to the presence of nickel ions. Varying concentration of imidazole was added to the column

CASE STUDY Gas and Grouse Introduction The objective of this case study is to investigate the various systemic‚ corporate and ethical issues behind Questar Corporation’s drilling operations on the Pinedale Mesa. Besides that‚ this case study is conducted to determine the value of wildlife species and its balance against the economic interests of Questar Corporation. Furthermore‚ it is also to determine whether Questar is morally obligated to cease its operations on the mesa and whether

are prime examples of the implementation of gas laws. The physics are based on the simple principle that warm air rises in cooler air. Hot air has less mass per unit of volume. The relevant gas law in use is Charless Law‚ which is V1/T1=V2/T2. The law states that raising the temperature (T1) will also increase the volume (V2)‚ in order to keep the equation true. Generally‚ air is heated through the use of propane burners. When ignited‚ the volume of the gas increases but the balloon cannot expand much

OVERALL Questar corporation is an energy company with asset valued at about $4 billion which is the main developer of the gas wells arround the Pinedale Mesa‚ an area that is famous at the gateway to the hunting‚ fishing‚ and hiking treasures. Ocassionally elk‚ mule deer‚ pronghorn antelope and other wild life‚ including the imperiled greater sage grouse‚ descent from their habitats atop the mesa and gingerly make their way around and between the questar wells around Pinedale.

Case: Gas or Grouse? 1. Systemic issues: Questar is a company and it knows that every mining activities in Mesa will affect the ecological environment. But BLM did nothing since Questar had damaged the local environment. And we know many gas companies have special relationship with governments. Corporate issues: Questar has destroyed the environment when the mining operation was begun. Individual issues: The people who live in Pinedale Mesa believe the drilling activity bring numerous

experiment is to identify an unknown proprietary drug using thin-layer chromatography. The unknown’s behavior in thin-layer chromatography will be compared with that of its possible component analgesics. The possible unknowns and their analgesic ingredients will be Anacin (aspirin‚ caffeine)‚ Excedrin (acetaminophen‚ caffeine‚ aspirin)‚ Motrin (ibuprofen)‚ and Tylenol (acetaminophen). Introduction Thin-layer Chromatography(TLC) was the method used to figure out and identify the drug. TLC is done
