Explanation:
-increases genetic variation
-increases the fitness of a species
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly 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. There are two types:
- somatic: these only occur within certain cells, and arise from environmental factors such as UV light
- hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.
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
.
e.g. sickle cell anemia, a disease caused by a mutation, confers protection against the disease malaria.

Hi lovely,
The answer you're looking for would be Biosphere.
Yeast fermentation produces ethanol and carbon dioxide.
- Fermentation is an anaerobic pathway that breaks down glucose in absence of oxygen.
- Conversely, cellular respiration requires oxygen to break down glucose molecules.
- Fermentation is energetically less efficient than cellular respiration in terms of the generation of energy (ATP).
In conclusion, yeast fermentation produces ethanol and carbon dioxide.
