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.

The best explanation as to why water forms beads on leaves with waxy cuticles would be the strong intermolecular forces between water molecules. The correct option would be C.

There are 2 types of molecular forces:

  1. Adhesive force: forces between molecules of different substances
  2. Cohesive force: forces between molecules of the same substance.

When the cohesive force between molecules is greater than the adhesive force, the molecules will cling more to themselves than to the molecules of different substance.

In other words, water forms beads on waxy surface of leaves because the cohesive force holding the water molecules together is stronger than the adhesive force between the water molecules and the waxy surface of the leaves.

Feather color in budgies is determined by two different genes, Y for pigment on the outside of the feather, and B for pigment on
Anvisha [2.4K]

Answer:

The two blue budgies are most likely to be yyBb each

Explanation:

there are 3 different scenarios possible for crossing blue budgies:

1) yyBB crossed with yyBB

this is not possible because it does not allow for the genotype yybb (white budgies)

2) yyBB crossed with yyBb

again, this cross will not yield the genotype yybb required for white budgies as given in the problem statement

3) yyBb crossed with yyBb

which leaves us with this option being most likely the genotype of the parent budgies who will have white budgies as offspring

Hope that answers the question, have a great day!
