prokaryotic. Prokaryotic cells are usually unicellular‚ while eukaryotic cells can either exist as a single celled organism or be found in multicellular organisms. The unicellular and multicellular organisms are linked to cell size and surface area to volume ratio. The experiment for cell size and diffusion was set to see how and how much water can go to the cells. This movement of water is called Osmosis. Osmosis is the movement of water molecules from an area of low concentration (lots of water) to

Understanding Gas-Condensate Reservoirs How does a company optimize development of a gas-condensate field‚ when depletion leaves valuable condensate fluids in a reservoir and condensate blockage can cause a loss of well productivity? Gas-condensate fields present this puzzle. The first step must be to understand the fluids and how they flow in the reservoir. Li Fan College Station‚ Texas‚ USA Billy W. Harris Wagner & Brown‚ Ltd.

Discuss why hydrogen bonding is essential for life Throughout biochemistry there are many bonds without which life as it is on earth today would not be possible. One of the most important bonds of these is the hydrogen bond‚ a weak chemical bond that is present in essential biological molecules such as water and polypeptides. A hydrogen bond is defined by Campbell and Reece as occurring when a hydrogen atom is covalently bonded to an electronegative atom but attracted to another electronegative

Chemistry 1061: Principles of Chemistry I Gas Laws Gas Laws: Pressure‚ Volume‚ and Temperature Introduction Pressure‚ volume‚ and temperature are properties of gases that reveal their relationships when any one of them is varied. Changing the temperature of a gas may change its volume or pressure‚ but how? What are the mathematical relationships between these properties? Are there limits to them? Scientists have discovered through the study of properties of gases that there is indeed a theoretical
