What cells are responsible for healing? Beyond the stem cell, three other types of cells are critical to the process of tissue repair: fibroblasts, endothelial cells and macrophages. In most wounds, complete replacement of wounded tissue to its original, unharmed state is impossible. Do immunosuppressants slow healing? The principal drugs that can slow wound healing […]

What is the relationship between absorbance and concentration?
What is the relationship between absorbance and concentration? One factor that influences the absorbance of a sample is the concentration (c). The expectation would be that, as the concentration goes up, more radiation is absorbed and the absorbance goes up. Therefore, the absorbance is directly proportional to the concentration. How do you calculate absorbance from […]
What is the first step in any design process?
What is the first step in any design process? Discovery is the first step of the design process, where teams work together to develop an understanding of the problem they are trying to solve, and define the path they will take to explore solutions. It culminates in the communication of a vision – a concise […]

Can electrons travel through air?
Can electrons travel through air? In order to create an electrical current, electrons must be ripped off of the air molecules so that they are free to move and form a current. Rather, air displays a complex relationship between the applied voltage and the resulting electrical current traveling through the air. Can current flow in […]
How do genes influence traits?
How do genes influence traits? Genes (say: jeenz) play an important role in determining physical traits — how we look —and lots of other stuff about us. They carry information that makes you who you are and what you look like: curly or straight hair, long or short legs, even how you might smile or […]
