Duplications involve the production of one or multiple copies of a specified region of the genetic code
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly condensed and wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.
Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell. During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes.
Duplications involve the production of one or multiple copies of a specified region of the genetic code.
Like other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations are maintained within cells, as they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring a protective advantage.

Answer:c) glucose
Explanation: The complete balanced chemical equation is C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy.
The equation above represents cellular respiration. During respiration, one molecule of glucose (C6H12O6) is broken down in the presence of six molecules of oxygen (O2) to produce six molecules of carbon dioxide (6CO2), six molecules of water (6H2O) and energy (ATP).
Answer: the glucose is a weird circle thing and a french fry is a food.
Explanation: not really understanding the question here...
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide in the process of respiration, which is then used in photosynthesis. While water is broken down to form oxygen in photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. ATP is manufactured as a result of several processes including fermentation, respiration and photosynthesis.
Answer: Characteristics: The fins are supported by rays, as the name indicates. In contrast to the cartilaginous fish they have a rigid skeleton. The swim bladder is also a unique feature of most ray-finned fish, enabling them to maintain buoyancy as they move up or down in the water.
