Answer:
It activates Cdc25, which in turn activates more M-Cdk
Explanation:
Cyclin are enzymes that regulate cell cycle progression by the activation of cyclin-dependent kinases (CDKs). These cyclins have no enzymatic activity on their own but they can activate Cdks by binding and phosphorylating them. CDKs can be activated by phosphorylation of activating sites and/or dephosphorylation of inactivation sites. Moreover, M-phase cyclins are cyclins that form M-CDK complexes in order to modulate the cell's entry into mitosis. Cdc25 is a phosphatase involved in the eukaryotic cell cycle which is well-known to regulate the entry into and progression during S (DNA Synthesis) phase and mitosis. In this regard, it has been shown that mitotic phosphorylation of Cdc25 by M-Cdks increases its intrinsic phosphatase activity, thereby Cdc25 is able to remove inhibitory phosphates from M-Cdk and, consequently, activate more M-Cdks.
Answer:
Jack
Explanation:
Biological organisms tend to undergo anatomical changes as they transition into their adult stage. In the next 5 years, as Jack transitions into adulthood, he will likely grow taller and stronger, and will undergo neurological and hormonal changes (changes of the brain and body chemistry).
Overall, Sam can be said to be the one to "change the most" during the next 5 years when compared to someone who's is already an adult, or something inorganic and somewhat durable like a signpost.
(D) Lymphatic system
(I think lol)
One of the Lymphatic systems major jobs is to collect extra lymph fluid from body tissues and return it back to the blood.
