Tundra ecosystem is cold and sunlight is short. Plants need sunglight and warmth in order to grow, thus plants in tundra are shorter and cloers to the ground since the ground is warmer than the air
Answer:
<h2>
Phosphorylation and dephosphorylation plays an important role in activating or inhibiting different proteins.</h2>
Explanation:
1. When Cdc25 is phosphorylated by M-Cdk, it activates the CdC25. It acts as checkpoint from G1 to S and G2 to M.
So, the correct answer is activates (A).
2. Phosphorylation of condensins by M-Cdk, degrades the condensin and begins the decondensation of chromosomes. That means it inactivates the condensin.
So, the correct answer is Inactivates (I).
3. Phosphorylation of APC/C activates it and then CdC20 can bind to it and then cell will progress through anaphase.
So, the correct answer is Activation (A).
4. Phosphorylation of Ndc80 by Aurora-B leads to binding of NdC80 to kinetochore and recruits the Ska complex at kinetochore.
So the correct answer is activates (A).
So, four-letter string is AIAA.
If you are asking if it is a true or false statement, it is a false statement. A mutation cannot possibly occur during polypeptide production or any protein synthesis or process. However, mutation may occur if the protein or enzyme is involved in any DNA replication or transcription process.
Insoluble fiber does not absorb or dissolve in water. It passes through our digestive system in close to its original form. Insoluble fiber offers many benefits to intestinal health.
They don't require big ones because they're able to keep moving and provide food and energy for themselves while plant feels are not able to do the same, thus giving them lather vacuoles.
