Nanotechnology is a field of producing materials and devices from atoms and molecules.
Explanation:
Nanotechnology is a field that concerned with producing materials and devices from atoms and molecules. A nanometer is one-billionth of a meter in size. Nanotechnology can be used to “recognize” the cells of interest which allows associated drugs to reach diseased tissue without damaging healthy cells. Nanotechnology produces new and faster kinds of computers, more efficient power sources and more effective medical treatments. Main disadvantages include threats to security, privacy, health and the environment. More research must be done in this field to get more benefits from it.

A) <u>Mutation</u> is the original source of variations for plants and other organisms which develops differences among their respective species
Explanation:
Genetic variation leads to the natural differences between each individual and among individuals of a species. The main cause for this variation is due to alleles that cause variations in the composition of genes or the DNA sequences.
A mutation is a genetic variation which leads to the creation of a new allele in a species population. Each variation in the DNA sequence leads to an allele formation and each allele leads to a difference in character or trait between individuals since they are the alternate version of the original genes.
Although genetic variations could be brought about by crossing over, random fertilization, or independent assortment; mutation is the original source because it provides the basic raw material for all the evolutionary changes.
The ozonosphere is another term for the ozone layer, which is within the Earth's stratosphere. The ozone layer is responsible for absorbing most of the sun's ultraviolet (UV) radiation, thanks to its high concentration of ozone that is exclusive to this layer.
