Explanation:
Answer:
on the surface rapidly
Explanation:
Obsidian glassy texture indicates that the rock formed on the surface rapidly.
Like every other magma, the condition of the environment determines how the magma cools and solidifies.
- When magma cools rapidly, nucleation centers will be difficult to come- by ..
- At nucleation centers, minerals aggregates and grows to form different grain sizes.
- When rapid cooling occurs, not enough time is given for the aggregation around the nucleus.
- This leaves a rock mass that is finely grained.
Answer:
Explanation:
A tRNA with the complementary anticodon is attracted to the ribosome and binds to this codon. The tRNA carries the next amino acid in the polypeptide chain. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids
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.
