Do some research on what it means to make good backups. For example RAID Is Not A Backup, Simple Copies Are Not Backups, Copies On Same Media Are Not Backups, etc. Agreed. I do use backups on the same Media, however this is something which is annoyingly hard to remedy (in my situation at least). The main issues I have had is when a damp cable tipped a microvolt meter and killed the server, luckily I had a backup (which was an exact clone of the corrupted world files).
Owing to their structural differences, eukaryotic and prokaryotic cells do not divide in the same way. Also, the pattern of cell division that transforms eukaryotic stem cells into gametes (sperm cells in males or egg cells in females), termed meiosis, is different from that of the division of somatic cells in the body.
The most basic kind of stem cells are the cells that make up an embryo soon after an egg is fertilized. These stem cells divide over and over, eventually making almost all the different cells in the body. Adult stem cells, in contrast, are fully differentiated.. That means they are what they are and do what they do.hat they have in common is that they have the ability to make other types of cells. No other cell in the body can do that. Some stem cells can renew themselves and become virtually any cell in the body.
