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.

According to your diagram A comes first. It’s true because if it doesn’t evaporate everything else can’t happen.
The awnsers would be D for the first one and A for the second. Let me know if you want an explanation.
The heat generated by this absorption is emitted as longwave infrared radiation, some of which radiates out into space. The solar radiation (the energy) that passes through earth's atmosphere is either reflected off snow, ice, or other surfaces by the earth's surfaces
Charles Darwin was B. A Naturalist on the Beagle voyage to South America. A naturalist observes and collects plant, animal, rock, and fossil specimens.
