Web5 jan. 2013 · Osteoporosis is a disorder in which the bones become unusually porous and brittle and bone density decreases. The condition generally appears in older people, although it occurs in young ones as well. In osteoporosis, the amount of bone resorption is much higher than the amount of bone production. Web28 apr. 2024 · Mitosis Definition. Mitosis is the step in the cell cycle that the newly duplicated DNA is separated, and two new cells are formed. This process is important in single-celled eukaryotes, as it is the process of asexual reproduction. In multi-celled eukaryotes, mitosis is how a single zygote can become an entire organism.
