Answer: do you know Spanish?
Explanation:
Answer: MITOCHONDRIA: cell respiration
ENDOPLASMIC RETICULUM: transport &making organelles and proteins
Explanation:
Mitochondria are used for cell respiration, which is the process that gathers oxygen. This oxygen is then burned by the mitochondria and turned into energy.
Smooth ER's are used for making organelles.
Rough ER's are used to make proteins, as well as for transport.
Answer:
The nucleosome is extremely stable.
Explanation:
The nucleosome when formed is extremely stable the histones are positively charged and the DNA wrapped around them are negatively charged, they have to be stable so as to be able to control the processes of replication, repair, transcriptional activities etc
Some processes including epigenetic mechanisms exist to destabilize the nucleosome. This is to help transcriptional machines fain access to the DNA for mRNA production. The nucleosome is so stabilized that it ensures transcriptional activities takes place at the only the right time and can also return back to its norrmal state when not needed.
Some processor that destabilize nucleosome includes
Acetylation: acetylation of some lysine residue on histone bring about destabilization: unwinding of the history from the DNA.
Histone chaperones: this too aids in the destabilization of the nucleosomes.
Topoisomerases activity: this helps in the unwinding of the DNA to allow transcriptional machineries to have access. ETC.
Answer:
plants have a weaker cell and is kind of shaped like a octagon and they feed off water and the whitefish cells act like a human cell so everything is different it takes more for the cell to survive and the cell wall is not stuck in one shape it can change its movement
