The right answer is Regulating protein agents.
The regulating protein agents they are talking about is certainly the cyclin, especially cyclin B.
Cyclins have no enzymatic activity, they are regulatory proteins necessary for Cdk to be enzymatically active.
The activation of the Cyclin B / Cdk1 stock is the result of a series of complex and interdependent reactions:
When replication is complete, the Cdc25 phosphatase is no longer sequestered in the cytoplasm and passes into the nucleus, and at the end of the G2 phase, the Cdc phosphatase is activated, probably by phosphorylation by the Polo kinase. Cdc 25 then acts to remove the two phosphates inhibitors Cyclin B / Cdk 1 (after that, there is a process of self-activation).
Cyclin B / Cdk 1 complexes, once activated, allow entry into mitosis. For this, they intervene by triggering a number of phenomena that take place at the beginning of mitosis, that is to say in prophase.
Answer: Like the unicellular organisms that came before them, multicellular organisms developed when conditions were ideal for their development. The rise of multicellular organisms allowed for Earth to develop, or evolve, a wide range of life forms.
Explanation:
Asexual reproduction occurs by cell division during mitosis to produce two or more genetically identical offspring. Sexual reproduction occurs by the release of haploid gametes (e.g., sperm and egg cells) that fuse to produce a zygote with genetic characteristics contributed by both of the parent organisms.
