A water reservoir is a natural or artificial lake in which water is stored for human use. The only process that can take water from the atmosphere (vapour) to a water reservoir is
precipitation.
Precipitation is the process in which small water particles collide and join, making bigger water drops that will eventually be too heavy and fall to the ground in a process otherwise known as rain (if the water is in liquid state).

Answer:
adenosine triphosphate (ATP)
Explanation:
Active transport mechanisms require the use of the cell's energy, usually in the form of adenosine triphosphate (ATP).
Answer:
Scientists define density as the mass of a substance per unit volume. The word “per”
signals that thinking about density requires thinking about a relationship. It is the relation
between the mass (or weight) of one unit of a material and the volume of that one unit.
Density cannot be directly perceived or measured. It must be inferred from the
relationship of the mass and volume. However, it can be determined by calculation
which is how many schools teach it. To calculate density, you first measure the weight
and volume of an object precisely, then you divide the mass by the volume (i.e. d=m/v,
density equals mass divided by volume). So for example, the density of water is 1 gram
per cubic centimeter because a volume of 1 cubic centimeter of water has a mass of 1
gram. A substance which has a mass of greater than one gram per cubic centimeter
has a density greater than 1.0 gram per cubic centimeter; a substance which has a
mass of less than one gram per cubic centimeter has a density of less than 1.0 gram
per cubic centimeter.
