Answer:
In a cell, there are two kinds of gradients found, that is, chemical and electrical. The electrical gradient is produced by the net charge of negative and positive charges found across the membrane. The chemical gradient is produced by the concentration of ions across the membrane. In combination, it is called the electrochemical gradient, which in general function in reverse directions.
The procedure where pumping of ions takes place across the membrane via ion pumps against the electrochemical gradient is known as the active transport. This mode of transport sustains the balance of ions across the membranes and is dependent upon energy. The ATP is provided by the metabolic activities of the cell.
Answer:
Blueshift is observed when relatively large lattice spacing is decreased due to radiative dipole interactions between nanoparticles.
Having a psychologist or therapist of the same sex is not among the factors
which work together to produce a successful treatment.
According to the American Psychological Association (APA), there are three
factors which work together to produce a successful treatment and they
include the following:
- Clinical expertise of the medical professional
- Patient's values and culture.
This makes having a medical professional of the same sex the most
appropriate choice.

The answer is B. germline mutation.
The germline mutation is heritable variation in the lineage
of reproductive (germ) cells. Germ cells are cells that give rise to the gametes, so a
mutation in germ cell will be seen in a sperm cell or egg cell but not in a skin cell, for example.
The point mutation is the changes in a single
nucleotide base on the DNA molecule.
Frameshift mutation, due to addition or
deletion of a base, results in the change of reading frame and totally
different translation

cells and is not passed on to the next generation. </span>
