Answer:

The radial velocity curve describes how fast a star is moving in its orbit around a center of mass ( m )

Curve amplitude : This is the maximum value of the radial velocity curve

Radial velocity shape ; The shape of Radial velocity curve is parabolic in nature

Orbital period : Orbital period is the time taken by the star  to make one complete rotation in its orbit

Explanation:

The radial velocity curve describes how fast a star is moving in its orbit around a center of mass ( m ) while Curve amplitude  is the maximum value of the radial velocity curve also The shape of Radial velocity curve is parabolic in nature. and  Orbital period is the time taken by the star  to make one complete rotation in its orbit

How does insulin bind to cells and the mechanism involved in triggering the cells to take in glucose
Lera25 [3.4K]

Explanation:

Once blood glucose levels increase, pancreatic insulin migrates into a fat cell via the blood stream. Insulin then binds in the plasma membrane of the cell to an Insulin Receptor (IR). Through autophosphorylation, phosphate groups are then added to the IR,  causing GLUT4 molecules to come to the cell's surface.
