What must happen to water in order for its dissolved minerals to be deposited?¿
Nitella [24]

Explanation:

The water must be cooled. Cooling water means the kinetic energy of the water molecule is reduced. Bombardment with the solute molecules reduces. In addition, The inter-molecular spaces between the water molecules reduce and therefore the number of solutes that can be accommodated in the inter-molecular spaces reduces. This is how saturation point is reached. Therefore as you coll the solution, the solute molecule precipitate from the water.

DNA sometimes has chemical groups attached, called methyl groups, that affect gene expression. Suppose that, during each hour, f
ira [324]

Answer:

f = m - u

Explanation:

DNA methylation is an important epigenetic modification associated with the regulation of gene expression. As such, the analysis of DNA methylation marks and the dynamics of this process may shed light on the genes that are being expressed at a given time in a given cell type/tissue. In the example above described, f is defined as the fraction of the DNA molecule that is methylated after one (1) hour, whose value can be estimated by subtracting u fraction (i.e., fraction of methylated locations that become unmethylated) from m fraction (i.e., fraction of unmethylated locations that become methylated).

In consequence, the equation is

f = m - u
