Through the phosphorylation, Cdks signal the cell that it is ready to pass into the next stage of the cell cycle. As their name suggests, Cyclin-Dependent protein Kinases are dependent on cyclins, another class or regulatory proteins. Cyclins bind to Cdks, activating the Cdks to phosphorylate other molecules.

The Inconsistencies of the data are led to further investigations conclude about data that are inconsistent with the current, scientific understanding of amphibian reproduction
Option B
<h3><u>Explanation:</u></h3>
Class amphibia is one of the classes under the phylum chordata. This class has typical reproductive features. They are the animals that can live in both land and water, and a few are exclusively aquatic. But they essentially need water for the fertilization process. This is because they generally undergo external fertilization and the females lay eggs beside the water body. The males eject the sperms in water which swim through the water into the eggs and fertilize them.
This is the days old theory regarding the amphibia fertilization. But if some new theory comes up someday, that readily don't exclude this theory. The new theory has to pass through several tests and various further investigations where it's seen if the new theory explains most of the amphibia reproduction or not. Then it can be approved along side with the old theory.
