Cellulitis: Cellulitis is a common skin infection caused by bacteria. Causes Staphylococcus and streptococcus bacteria are the most common causes of cellulitis. The skin normally has many types of bacteria living on it. When there is a break in the skin‚ however‚ bacteria can enter the body and cause infection and inflammation. The skin tissues in the infected area become red‚ hot‚ irritated‚ and painful. Risk factors for cellulitis include: • Cracks or peeling skin between the

Photosynthesis: Plant cells vs. Solar Cells Chevon Allen 01/23/2010 SCI-115 Professor Garcia Photosynthesis and the semiconductor-based solar cell are very similar process with different ways of reaching the same goal. In photosynthesis‚ plant cells harness the solar energy of the sun with carbon dioxide to transform water molecules into hydrogen‚ oxygen‚ and electrons. Just like photosynthesis‚ Semi conductor based solar cells harness the solar energy of the sun for the same purposes

Every cell in the body goes through a life cycle. Cells grow and divide to replace cells that are lost because of normal wear and tear or injury to them. All cells grow and die at different rates. The cell cycle can be divided into three periods: interphase‚ the mitotic phase‚ and cytokinesis. During interphase‚ the cell grows‚ accumulating nutrients needed for mitosis‚ preparing it for cell division and duplicating its DNA. During the mitotic phase‚ the cell splits itself into two distinct daughter

Animal cells do not have a cell wall. Instead of a cell wall‚ the plasma membrane (usually called cell membrane when discussing animal cells) is the outer boundary of animal cells. Animal tissues therefore require either external or internal support from some kind of skeleton. Frameworks of rigid cellulose fibrils thicken and strengthen the cell walls of higher plants. Plasmodesmata that connect the protoplasts of higher plant cells do not have a counterpart in the animal cell model. During telophase

renewable energy sources‚ fuel cell technology has received great attention as an alternative to the conventional way of getting energy due to its high efficiency‚ clean operation and cost efficient supply of power demanded by the consumers. Proton exchange membrane (PEM) fuel cells technology plays a leading role for many applications when comparing with other competitive types of fuel cells. The world is in high demand for clean alternative fuel source and PEM fuel cells could be that change with a

of the cell increases enormously during the action potential. Comte Whitney Electricity is vital for neural function and communication. The semi-permeable membrane and presence of charged particles in solution (ions)‚ enables the cell to have control of an electric potential. The cell The concentrations of Na+ and K+ ions upon either side of a cell’s membrane are not equal. In order for the equilibrium to be restored‚ sodium will attempt to enter the cell‚ whilst potassium will exit the cell. It is

Evolution of Eukaryotic Cells from Prokaryotic Cells DNA- Deoxyribonucleic acid (DNA)‚ a self-replicating material present in nearly all living organisms‚ is the acid that carries genetic information. RNA- Ribonucleic acid (RNA)‚ is an acid that is present in all living cells‚ it’s main role is to act as messenger and carry instructions from DNA fro controlling the synthesis of proteins. What are Eukaryotic Cells and Eukaryotic Organisms? A eukaryotic cell is a cell that contains complex

Cell Phone Policy Implementation The cell phone policy I would create will not be broad for its usage. I will also put the responsibility into the users hand and will monitor it monthly. I would begin by including members of management‚ human resources‚ technology support‚ general staff and legal department. Discuss the current cell phone environment to determine the need of cell phones. That will create a list of eligible employees for either smartphones for data usage and applications or just
