Ionic compounds are compounds that are formed together by a cation and an anion. A cation is an ion with a positive charge. For example, Na+ and Ca2+. An ion has a negative charge, like Cl- and OH-. There is a greater chance of forming an ionic compound when they have a great difference in electronegativity, the ability to attract electrons toward itself. In the periodic table, elements that are opposite to each other, more likely found in opposite sides, would be more apt to form an ionic compound. Example would be NaCl and CaCl2 or Ca(OH)2.
a short microscopic hairlike vibrating structure found in large numbers on the surface of certain cells.
Explanation:
either causing currents in the surrounding fluid, or, in some protozoans and other small organisms, providing propulsion.
<span>oxidizing substance removes electrons from another substance, which are then added to itself, the oxidizing substance becomes “reduced” (more negative). And because it “accepts” electrons .</span>
All organisms share certain characteristics of life, for example, all living things are made of cells and they must reproduce to make the next generation. Without these characteristics, there is no life.
