Answer:
Apoptosis does not involve:
c. lysis of the cell
Explanation:
Apoptosis is a programmed cell death that occurs under normal physiological conditions and in a controlled manner. Normally seen in cell turnover, embryogenesis, also involved in processes of immune, nervous and endocrine systems.
The main morphological and biochemical changes seen during the apoptosis are the fragmentation of DNA by endonucleases, nuclear, chromatin and cytoplasmatic condensation, apoptotic bodies formation (membrane bound-vesicles form of cell parts) and the phagocytosis (digestion) of those bodies by the scavenger cells.
Apoptosis is regulated by cell- signaling pathways, the caspases, a family of cysteine proteases, are the ones involved in the process.
In the process there is no lysis of the cell as this could lead to a inflammatory response (just happens in necrosis) which would affect contiguous cells, and will involve immune cells. In apoptosis there is just a membrane blebbing, but it does not loss its integrity.
The answer is false. It is because the way the food manufacturers abide food safety guidelines or how they manufacture food will affect a person's taste buds. Obsolete means out of date-- which, will not happen to our taste buds as it does not involve in how the manufacturers dealt with the food and makes our taste buds turn to out of date or have it less developed.
