The four types of tissue in the human body: A tissue is a group of cells that is from similar embryological origin and is specialized for a particular function. Four types: epithelial, connective, muscle and nervous.

You can remember this by recalling that current flows from anode to cathode in an ordinary diode; well, that is, if you use the trick of assuming that current is hole flow, rather than electron flow, a useful and common convention.
The anode is the electrode where oxidation occurs and electrons are lost. The cathode is where reduction takes place and electrons are gained. These reactions don't occur separately; they must work together in a reduction-oxidation reaction.For this next section, let's assume the electrodes are zinc and copper.o determine the voltage of any cell, subtract the electrode potential of the anode from that of the cathode and you get the electrode potential of the cell, or voltage. Eo cell = Eo cathode-Eo anode. Corrosion is when metal is gradually destroyed through chemical reactions, and it is a real problem in our daily lives.
