Electrolytic cell is the type of a cell in which current drive a non-spontaneous redox reaction. Redox reactions are reactions in which the oxidation number of the reactants are changed. To change oxidation number, electrons must either be added to or removed from the reactants. However, to observe the law of conservation of mass, all the electrons removed from one reactant or atom must be added to another one, therefore, the number of species lost by one substance is equal to the number of electrons gained by the other.
Lactate is produced by fermentation
There are two main types of research, which could be classified as manipulation and observation. Both types are fundamental in research.
<h3>Empirical research and evolution</h3>
Evolution is the subdiscipline in biology that studies how organisms change to adapt to challenging environmental conditions.
Empirical research refers to any scientific investigation in which conclusions are drawn from empirical evidence.
This type of research (empirical research) is based on observation of the natural world and experimental procedures.

Cell differentiation
each and every cell in your body has the same DNA. there are about 220 different types of cells in the human body and they are all different because of gene promoters and other factors that limit the production of proteins.
Answer:
a. can produce many exact copies of segments of DNA
Explanation:
PCR refers to polymerase chain reaction that replicates a gene or a DNA segment into multiple copies. For the purpose, primers, the sample DNA template to be amplified, nucleotide monomers and the heat-tolerant DNA polymerase enzyme (<em>Taq </em>polymerase) are mixed.
The heating of the mixture leads to the denaturation of the sample DNA. The mixture is cooled down to allow annealing of the primers to the DNA template which is then amplified by the enzyme <em>Taq</em> DNA polymerase. The reaction mixture is heated to allow denaturation of all the DNA molecules which in turn serve as a template and the process is repeated for several rounds according to the requirement of the copies of the sample DNA.
