B and O because of the antibodies in the blood O has none so it's a universal donor and B because it's the type of the blood
Weaker, less evolved living organisms die in relation to survival skills, but the better ones stay.
For artificial selection, people select organisms based on what advantages they have to make them better.
Answer:
Phosphorylation within the nuclear export signal interferes with the function of the signal.
Explanation:
In biochemistry, phosphorylation is the addition of a phosphate group (PO4) to a protein or other molecule. Phosphorylation is a major player in protein regulation mechanisms, preventing protein-catalyzed reaction product from accumulating in the body causing problems.
However, in some cases phosphorylation may cause nuclear accumulation of a protein in the nucleus of the cell. An example of this is the protein shown in the question above. In this case, phosphorylation in the nuclear export signal interferes with the signal function, resulting in protein accumulation in the nucleus.
IT IS POSSIBLE FOR PARTICLES WHICH A PREDOMINANTE POSITIVE VALENCE TO COMBINE WITH PARTICLES OF DISIMILER VALENCE FORM A NEW MOLECULE DISIMILAR FROM EITHER OF HOSTS.
