4. b/c it is capable of dissolving a variety of substances
5. excess water that literally runoffs on land or other terrains. (You may look up the scientific definition.)
6. Simply, evaporation is the process of which water turns into a gas or liquid due to heat acting on the substance.
7. Condensation has two definitions. I believe the context you're looking for is the process by which gas or water vapor turns into liquid.
8. Transpiration is like, i guess i could call it a process; the precess of the movement of water through a plant and its evaporation through the leaves of the plants, well more specifically, its aerial parts.
9. water is taken up from the roots then released as water vapor through the leaves.
10. They are all significant parts. If there were no precipitation, there wouldn't be the process of evaporation or condensation. Condensation allows liquid to precipitate and rain (precipitation) allows for evaporation. If one of the three elements described is missing, their possibly wouldn't be a water cycle and therefore no life on earth.
Pesticide use can be very harmful beacause too much of them can cause the crops to go bad, and kill bees which help spread pollen and enhance the crops.
Lysozyme which is found in the lysosomes. They function at a relatively low pH and are so because if they functioned at physiological pH they would digest the cell. But in this case, they are in the lysosomes where they are safe and at a lower pH so when the vesicles open they can emit hydrogen ions and the lysozyme to digest the foreign material.
Nucleotides are joined together by covalent bonds between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar in the next nucleotide.
