Answer:
Somatic cells helps in healing and repairing damaged cells
Explanation:
Somatic cell division plays an important role in division of body cells. They help in healing and repairing the damaged cells. cell division is of two types, Mitosis and meiosis. Mitosis replicates and results in two identical daughter nuclei (genetically identical). Apart from these, they also act as adult stem cells which plays a major role in healing the damaged cells or repair the damaged cells. somatic cells are found all over your body except the germ cells.
Benefits of cell division in somatic cells:
- If you get hurt and eventually your blood will stop oozing out and get healed by the mitotic cell division found in the somatic regions of your body.
- Animals like lizards when get hurt, they get their cells automatically repaired by their somatic cells.
These are few important benefits other than the identical copies that are obtained by cell division.
Life is found almost everywhere on Earth, but it is not distributed evenly around the planet. Different species are found in different areas; some species have overlapping ranges, others do not. Each species has a set of environmental conditions within which it can best survive and reproduce. Not surprisingly, those conditions are the ones for which it is best adapted. Many different physical, abiotic (non- living) factors influence where species live, including temperature, humidity, soil chemistry, pH, salinity and oxygen levels.
Natural selection refers to the phenomenon by which the species in a population possessing the tendency to get adapted in a condition enhance in numbers in comparison to those who exhibit fewer adaptation capacities over a number of generations.
In other words, it can be stated as the non-random and differential development of distinct genotypes function to sustain favorable variant and to eradicate less favorable variants. Some of the conditions are required for the process of natural selection to take place.
These are heredity, reproduction, variation in individual characters, and variation in the fitness of organisms among the members of the population. If the conditions are met, then the phenomenon of natural selection occurs by default.
