The description describes metaphase, so the next step is anaphase
Answer:
b. to amplify the signal
Explanation:
A multi-enzyme phosphorylation cascade is a series of signaling events where one enzyme phosphorylates to another, then this last enzyme acts to phosphorylate another protein and so successively, thereby triggering a chain reaction that leads to the phosphorylation of hundreds or even thousands of proteins. A multi-enzyme phosphorylation cascade is known to increase the number of activated (phosphorylated) proteins at each step of the signaling cascade. Phosphorylation is a posttranslational modification capable of activating proteins during long periods, thereby a phosphorylation cascade also enables the activation of multiple proteins before these proteins become inactive again.
Answer:
I) Presence of nuclear envelope
II) Presence of membrane-bounded organelles
Explanation:
Unlike prokaryotic cells, eukaryotic cells possesses nuclear membrane and membrane-bound organelles. As a result, they undergo mitosis and meiosis.
Examples of organisms with Prokaryotic cell are bacteria, cyanobacteria
Examples of organisms with eukaryotic cells are green plants, fruitfly etc
An acronym for change would be preserve because that means keep
