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.
Answer: nucleotide A will bind to nucleotide T during DNA replication.
Explanation:
In DNA replication, Adenine(A) pairs up with its complementary base Thymine(T). The DNA polymerase which is an enzyme ensures that the nucleotide with base T binds to the base A of parental nucleotide.
Not a because a is a catalyst , not b because they do always need a catalyst , not d because catalyst are not required so it’s either c or e
The distance from the Sun allows for the right amount of light absorption, allows the right intensity of heat, and the gravitational pull of the sun on the earth keeps it from going out into outer space.
Hope this helped :)
