The basis of prion diseases is another. Yes, you can really tear a muscle, this is not fun. But, if you also consider the microbes that live in and on our bodies as part of "us" then they might not die and could exist in the environment indefinitely. After the brain is injured, some cells die but others start working to repair the damage.
This function is probably less affected by that cell cake that you are eating right now. Biologists used to think that new brain cells only developed very early in life when the brain was forming. An example for this is that there are two kinds of bats, big ones mega bats and small ones micro bats.
With enough alcohol or over a long time, cells can die. Robert Hooke first identified cells by looking at thin slices of cork. Well, there are mutations that you get from your mother and father and some mutations that may happen to your DNA during your life.
Difference between a zygote and an immature sex cell? Humans begin as a single cell when the sperm and the egg fuse during fertilization to form a zygote. These are formed by the process of meiosis, which can turn a diploid cell into four haploid gametes.
In this system, male or female develops based on the ration between X chromosomes and the numbers of Autosomes sets. What are the differences between somatic cells and egg cells? How many pairs of autosomal chromosomes are in a human somatic cell?
Mitosis- Cell division involving body cells. From there, the zygote will undergo mitosis to create more identical cells, and eventually, these stem cells will undergo differentiation to create different types of somatic cells.
Some cells die after a few minutes like brain cells , some can be recovered after 24 hours like skin cells. There is a lot of research going on to figure out how to enhance this natural regeneration to treat diseases that cause specific nerves in the brain to degenerate.
They may have all kinds of other features some of which may exist in terrestrial cells but maybe not together and some features that we have never seen before, even if they are from earth-like planets. If you consider the bacteria that live in the body as part of them, those bacterial cells can live and grow for weeks.
