Explanation:

ABCDECDEFG

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.

The rock below is in Whistler, Canada. What type of weathering is illustrated here?
MArishka [77]
Weathering is the process by which rocks are broken down into smaller particles as a result of physical and chemical changes that are occurring in them. There are three major types of weathering these are: physical, chemical and biological weathering. 
For the question given above, the type of weathering that is occurring in the picture of the given rock is PHYSICAL WEATHERING.
Physical weathering is the type of weathering in which the affected rock is changed in size and shape by means of some agents. The broken particles are usually of the same composition as the parent rock. The agents of physical weathering include: ice, plant roots, animal activities, abrasion and exfoliation. Physically weathered rocks are usually round in shape as a result of the abrasion process which they have undergone.<span />

A research biologist is studying cells from a new organism recently discovered in the Brazilian rain forest. She determines that
scoray [572]

Answer:

(2⁵)²: 1024 combinations

Explanation:

In this case, the chromosome haploid number (n) of the target species is equal to 10, and therefore its diploid number (2n) is equal to 5 (i.e., somatic cells in the target species contain 5 pairs of chromosomes). That means that one individual can produce 2⁵ or 32 different gametic combinations. Moreover, the number of possible combinations that emerge from paring different gametes (sexual reproduction) can be calculated as (32)² = 1024 combinations.
