Saccharides are the monomers which are combined to form carbohydrates.
Depending on the type of carbohydrate, the monomer components can be monosaccharides, disaccharide, polysaccharide, etc.
E.g: Sucrose is a carbohydrate (specifically a dissacharide) that is made of glucose and fructose monosaccharides.
Another example is cellulose, which is a carbohydrate (specifically a polysaccharide) that is made of beta glucose monosaccharide components combined together.

4. fossilized plants or air bubbles ( probably the plants tho)
5. increased
6. the green house effect occurs naturally, it is being polluted both naturally and unnaturally, the unnatural pollution is contaminating our 'greenhouse" and that is horrible.<span />
Velocity can vary as long there is specific direction (displacement)
Speed has no direction therefore change in speed is not necessary the velocity...
Velocity is also in a specified direction
