Describe an example of a molecule(s) transported by active mediated transport (facilitated diffusion). How do cells communicate with one another? Explain how the plasma membrane helps with this function. Why is a transport protein required to move water through the membrane? Explain. Discu...
1. Water is actually quite simple, but the way how the water molecule is formed gives water its unique properties.2. Water is a liquid at room temperature and has a relatively high frozen point.3. The nutrients in whatever falling into the ocean will quickly become available to other ...

An air mass is a very large volume of air that is relatively consistent in temperature and humidity throughout the mass. Air masses move around the earth, creating varying weather and climate patterns. Air masses differ greatly in their temperature and moisture content, based on where they ...

where C is carbon, H is hydrogen, O is oxygen and each hyphen is a chemical bond between the atoms. For clarity, the bonds of the three hydrogen atoms to the left carbon atom are not shown. The OH (O - H) group on the molecule is what makes it an alcohol. There are four types...
Another type of particles that draw large attention is polymer nanoparticles [44]. These types of nanoparticles (Figure 13) are easily made-mostly from biodegradable polymers and can increase the stability and time of circulation. Moreover, in addition of being non toxic, other advantages of these...
When large molecules cannot be trasnported into a cell by difussion or active pumps, the cell membrane can in essence reach out and engulf a molecule... Learn more about this topic: Endocytosis and Exocytosis Across the Cell Membrane from...
During the extrusion process, a large quantity of water is used to cool the molten nylon. Depending on the manufacturer, this contaminated water may or may not be disposed of properly. After the polyamide fibers are loaded onto bobbins, they are stretched to improve their elasticity and streng...
