The answer would be osteoporosis
Osteoporosis comes from word osteo- which mean bones and -porosis which means "pore". The term is used to describe a decrease in bone density which makes them seems like having multiple pores. It is found more in the old patient because the bone formation is decreased.
The cell cycle involves the growth, replication, and division of a eukaryotic cell. Mitosis most directly plays a role in the division of a cell's nucleus.
Mitosis is the process that takes place in the somatic cells or the body cells, where the diploid cells divides to yield two diploid daughter cells. The process occurs in five stages which includes; interphase, prophase, metaphase, anaphase and telophase.
<span>It may be difficult for ecologists to determine the size of a bird population if that population migrates to different locations throughout the year. During migration, some birds may split off from the group and not return, others may die, and still others may join. Therefore, the bird population will be in constant flux. It is hard to know, when the birds return to their prior location, if the population consists of the same group of birds (in addition to deaths and births) or whether it has grown or shrank through other means. However, to estimate the size, an ecologist can track a migratory flock through several years, counting each year to get a general sense of the population size. Additionally, given one measurement, an ecologist could consider the average lifespan and birth rates of the population to extrapolate the size of the population in subsequent years.</span>

The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
