Answer:
The magnitude of the magnetic field is 0.156 T.
Explanation:
Given that,
Speed of a proton, 
Radius of the circular path, r = 0.2 m
When the proton enters in the circular path, the centripetal force is balanced by the magnetic force such that :

q is the charge on proton
Here, 

So, the magnitude of the magnetic field is 0.156 T. Hence, this is the required solution.
a. cell shape- It is cell shape because not only are the other 3 nonsensical, the cytoskeleton is for the framework and movement of a cell.
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
