Corrosion is defined as an attack on a material as a result of chemical, frequently electrochemical reaction, with the surrounding medium. According to this definition, the term corrosion can be applied to all materials, including non-metals. But in practice, the word corrosion is mainly used in conjunction with metallic materials.
An oxidizer is a substance that is not that combustible, but can possibly release oxygen and will contribute to a certain materials' combustion.

What is the significance of corrosion rate and how will you incorporate this in structural design? If the surface area of a more noble metal is doubled what will happen to the corrosion rate when connected to a less noble metal? Explain why.

Roles of the Na+/ K+ pump 1. Maintain the Nat/K+ concentration gradicnt across the plasma membrane. (That's obvious) 2. It plays a role in maintaining the resting membrane potential. Why? 3. The steep electrochemical gradient of Na+ is used in "coupled active transport" (coupled pumps). If the Nat/K+ pump stops, then these Na+ coupled transport mechanisms will also eventually stop. Explain The apical surface of the epithelial cells that line the lumen of the gut contains a symport that used...

Most cancer medications kill rapidly dividing cells, such as those in tumors. Two common side effects of cancer medications are hair loss and digestive tract upsets. Make a hypothesis about why these two side effects are seen in people taking cancer medications, and explain your reasoning. (Hint: The cells on your scalp and those that line your digestive tract are both part of surface tissues called epithelia. Your skin is also an epithelium. Have you ever noticed how you constantly...
