Answer:
C. glycosylation
Explanation:
The maturation-promoting factor (MPF) is a cell cycle checkpoint that stimulates the passage from G2 (prophase) to M phase (metaphase). MPF also determines that DNA replication during the S (synthesis) phase did not produce any mutations. MPF is inactivated by kinase phosphorylation and activated by specific phosphatases capable of dephosphorylating this protein. On the other hand, glycosylation is a posttranslational modification where a carbohydrate (i.e., a glycan) is added to a functional group of another molecule. Many proteins undergo glycosylation, thereby playing a critical role in regulating protein function.
Answer:
b. thrive during the summer, when sunlight increases
Explanation:
Phytoplankton production is highly associated with latitude and season. In polar regions, phytoplankton production is reduced to the summer (and eventually spring) season. In consequence, the zooplankton that eats phytoplankton only can survive during the spring and summer seasons. On the other hand, in tropical areas, there exists a nearly constant phytoplankton production all year round.
