3 characteristics of the carbon atom that makes possible the building of variety of biological molecules are:
• Carbon atoms can easily form covalent bonds with nitrogen, hydrogen, oxygen, sulfur and with carbon. The bonds can be single, double or triple between the atoms. This combination of carbon with other elements and with itself results in the formation of huge number of biological molecules.
• The size of carbon atom is very small in comparison to most other atoms. Thus, the bond formed between two carbon atoms is quite short. And the shorter bonds are more stronger than the longer bonds between two atoms, that's why carbon bonds are stable at the different temperatures associated with life.
• Only carbon can form stable four covalent bonds with the other elements, which makes it versatile element to serve as the basic structural component, of the macro-molecules.
At the sea shore there is less water so the sun shines directly in them, deeper. there is more water. so their bodies are more in the water therefore the sun is less in their bodies.
<span>B.) When heated water becomes water vapor and turns from a liquid to a gas, "Evaporation" is Occurring.

Answer:
According to Le Chatelier’s Principle, a stress placed on a system at equilibrium will cause the equilibrium to shift to counteract the stress. For example, a temperature increase in the above reaction will favor the reverse reaction to use the excess heat and form brown NO2 gas. A temperature decrease in the above reaction favors the forward reaction to produce heat and form colorless N2O4 gas.
