One question that constantly arises, however, is whether autophagic activity in dying cells is the cause of death or is actually an attempt to prevent it. Morphological and histochemical studies have not so far proved a causative relationship between the autophagic process and cell death.
Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
Animals in a social group (of kin) often work cooperatively in order to survive, but when one member perceives itself as a burden for an extended period of time, it may commit self-destructive behavior. [7] This allows its relatives to have a better chance at survival, and if enough close relatives survive, then its genes get indirectly passed ...
The human body contains many types of cells and a human can be killed by the loss of a single tissue in a vital organ [citation needed]. For many short term radiation deaths (3 days to 30 days) the loss of cells forming blood cells ( bone marrow ) and the cells in the digestive system (wall of the intestines ) cause death.
Experts interviewed for the show explain that sometimes the killing of the animal is to prevent it from further attacks on humans; other times, the animal is euthanized in order to retrieve the body of the victim; still others are killed as routine legal procedure, applied to any animal that injures or kills a human, in order to perform a ...
